To evaluate the long-term changes in retinochoroidal structure and perfusion status in highly myopic eyes following ICL V4c implantation, using ultra-widefield swept-source optical coherence tomography angiography (UWF-SS-OCTA) combined with a three-dimensional modelling algorithm. Prospective cohort study. Sixty-six highly myopic patients (132 eyes) underwent ICL V4c implantation surgery and completed one year of follow-up. Retinal and choroidal parameters, including retinal thickness (RT), capillary plexus density, foveal avascular zone (FAZ), retinal curvature, choroidal thickness (CT), and three-dimensional choroidal vascularity index (3D-CVI), were measured preoperatively and at multiple postoperative time points using UWF-SS-OCTA integrated with advanced 3D analytic techniques. Repeated measures mixed-effects models were applied to compare the pre- and postoperative parameters and test the correlations between parameters. The surgical outcomes are satisfactory with a stable safety profile and no major complications. RT and retinal vascular density exhibited transient changes in one month postoperatively, and gradually recovered (p < 0.05). Choroidal parameters, including CT and 3D-CVI, demonstrated a progressive and sustained postoperative increase across the 1-year follow-up, with the most pronounced changes observed in the foveal and perifoveal zones (p < 0.001). Factors of surgical duration and axial length showed significant correlation to the retinochoroidal responses (p < 0.05). Our analysis based on UWF-SS-OCTA demonstrated that ICL implantation can cause the recoverable changes of retinal structure and perfusion status, and the sustained remodeling of choroidal vascular conditions one year postoperatively in high myopia. Trial registration number : ChiCTR2500108664, registered at the Chinese Medical Research Registry. ICL implantation is an effective intraocular refractive procedure for high myopia, but its impact on retinochoroidal structure and perfusion remains incompletely understood. Conventional assessments of retinochoroidal parameters have predominantly relied on two-dimensional measurements. This study provides 3D evaluation of retinochoroidal structure and perfusion using UWF-SS-OCTA combined with AI-based reconstruction, enabling more comprehensive assessment of postoperative changes. ICL implantation induces transient retinal alterations but sustained increases in choroidal thickness and vascularity, suggesting long-term choroidal remodeling in highly myopic eyes.

AIM: To compare the accuracy of manual marking versus an image-guided system for toric implantable collamer lens (TICL) implantation and evaluate the short-term postoperative rotational stability of TICL and corneal surgically induced astigmatism vector (SIA). METHODS: Retrospective analysis was conducted on eyes with TICL alignment achieved through manual marking (n=75) or VERION image-guided system-assisted marking (n=83). Each group was further classified into horizontal and vertical subgroups based on implant orientation. Additionally, patients were categorized into superior and temporal incision subgroups according to the position of main corneal incision. The misalignment and rotational stability of TICL were analyzed using slit-lamp anterior segment photography. Surgical predictability, efficacy, safety, and corneal SIA were also evaluated. RESULTS: In general, the TICL implantation with manual and digital image-guided systems all achieved robust predictability, efficacy, and safety. The misalignment of TICL was comparable between the manual and VERION groups (0.16°±3.97° vs 0.52°±5.59°, P=0.633), while a significant difference was observed in the absolute misalignment of TICL between the two groups (3.02°±2.55° vs 4.28°±3.61°, P=0.043). There were no significant differences in the distribution of TICL misalignment between the manual and VERION groups or between horizontal and vertical implant orientation groups (P>0.05). Furthermore, different orientations of TICL placement did not show statistically significant differences in rotational stability (P=0.46). Statistically significant differences were found in anterior corneal SIA between the manual and VERION groups (0.46±0.27 vs 0.33±0.21 D, P=0.001), especially for superior incision position (0.60±0.27 vs 0.35±0.23 D, P<0.0001). The anterior SIA exhibited a significant difference between superior and temporal incisions in the manual group (0.60±0.27 vs 0.35±0.20 D, P<0.0001). CONCLUSION: Compared with the conventional manual marking method, this study indicates that the digital image-guided system with VERION is safe and effective in TICL implantation. The digital system offers the advantage of minimizing corneal SIA compared to the manual method.

The transcription factor interferon regulatory factor 3 (IRF3) initiates type I interferon transcription, which is required for host defense. Here, we identify RAD18 as a central E3 ubiquitin ligase that selectively targets phosphorylated IRF3 (p-IRF3) for autophagic degradation. RAD18 specifically promotes the dissociation of p-IRF3 from the IFNB promoter and in turn terminates its transcriptional activity. Mechanistically, RAD18 binds the p-IRF3 dimer located on the IFNB promoter and triggers K63 polyubiquitylation of p-IRF3 at Lys 193. The ubiquitylated p-IRF3 dimer consequently dissociates from the IFNB promoter, translocates out of the nucleus and undergoes OPTN-mediated autophagic degradation. Rad18fl/fl Lysm-cre mice resist lethal vesicular stomatitis virus infection in vivo due to IFNβ overproduction. In H1N1-infected human macrophages or monocytes from individuals with active systemic lupus erythematosus, RAD18 protein levels negatively correlate with p-IRF3 and IFNB1 mRNA levels. Thus, RAD18 functions as a break to terminate IRF3-driven IFNB1 transcription and may be a potential therapeutic target for RNA virus infection or autoimmune diseases. IRF3 initiates type I IFN transcription, and this is required for host defense. Here, Chen and colleagues show that RAD18 terminates the transcriptional activity of IRF3 and subsequently promotes the autophagic degradation of IRF3.

PurposeThis study aims to conduct a bibliometric analysis of global publications on the application of artificial intelligence (AI) in high myopia (HM).MethodsWe retrieved publications on AI in HM from the Web of Science Core Collection (WoSCC) database, MEDLINE and Chinese Science Citation Database (CSCD) with data up to 2024.

Additionally, we explored research domains and emerging keywords.ResultsA total of 167 relevant publications were included. The first AI-related paper on HM was published in 2017, with a significant surge in 2021, followed by a consistent increase in publication and citation counts over the next 3 years. China emerged as the most productive country, with the most extensive international collaboration. East Asian authors dominated the top 10 most influential authors. Yang, Weihua and Investigative Ophthalmology & Visual Science (IOVS) contributed the most publications among authors and institutions, respectively. Keyword analysis revealed that retinal imaging-related terms remained a consistent research focus, while newly emerging keywords included “automated detection” and “childhood.”ConclusionRecent advancements in AI applications for HM have been significant and are expected to continue. Future research will likely focus on multimodal imaging and improving algorithm accessibility. Our findings offered the first comprehensive overview of global research on AI in HM, thus providing valuable insights for researchers to understand the current status and future trends in this field.

Purposes To evaluate the impact of coronavirus disease 2019 (COVID-19) on postoperative visual acuity, optical quality, and severity of dry eye disease in patients after small incision lenticule extraction (SMILE). Methods This is a retrospective, comparative study. Patients who underwent SMILE were included and divided into two groups according to the period at the eye center of the Second Affiliated Hospital of Zhejiang University. The first group included patients who underwent SMILE before the large-scale COVID-19 pandemic in China (Group 1). The second group comprised patients who underwent SMILE during the pandemic with a confirmed infection of COVID-19 (Group 2). The visual acuity, the severity of dry eye, ocular surface disease index (OSDI), oculus keratography analysis, and individual Zernike coefficients were evaluated and compared between the 2 groups. Results A total of 43 eyes of 23 patients and 45 eyes of 26 patients were included in Groups 1 and 2, respectively. The OSDI score in Group 2 was significantly higher than Group 1 (P<0.01). The corrected distance visual acuity (CDVA, logMAR) at 3 months postoperatively in Group 1 was better than in Group 2 (P<0.001). Despite the improvement over 1 month after the COVID-19 infection, the OSDI score was still higher in Group 2 than in Group 1 (P<0.01). The bulbar and limbal redness were significantly higher in Group 2 than in Group 1 at both 1 month and 3 months (P<0.05), while no significant differences were found in tear breakup time or tear meniscus height. Spherical aberration (SA) at the 4 mm zone was significantly higher in Group 2 than in Group 1 both at 1 month and 3 months (P<0.001), while no significant changes were observed in corneal total higher-order aberrations. No significant correlation was found between the bulbar/limbal redness index and SA. Conclusions COVID-19 infection impaired visual outcomes and aggravated dry eye severity among postoperative SMILE patients.

Objectives: To report the global burden of age-related macular degeneration (AMD) and associated risk factors between 1990 and 2021 by age, sex, and sociodemographic index (SDI) and to investigate the influence of the COVID-19 pandemic on AMD burden. Methods: Data on disability-adjusted life years (DALYs) of AMD were obtained from the Global Burden of Disease Study 2021. Joinpoint regression determined annual percentage change (APC) and average annual percentage change (AAPC). ARIMA model projected AMD burden trends, with additional analyses for frontier, decomposition, and health inequality. Results: Globally, AMD accounted for 578.02 (95% UI: 401.24-797.57) thousand DALYs in 2021, driven by population growth and aging. Age-standardized DALY rates (ASDRs) fell from 1990 to 2021 (AAPC: -0.69, 95%CI: -0.77 to -0.6), but increased in high-middle and middle SDI regions during the initial two years of the pandemic. ARIMA model forecasts a worldwide decline in ASDRs over the next 29 years. Sex disparities were significant, with women having continuously higher ASDRs, especially from 2019 to 2021. Despite some reduction in health inequality, an inverse SDI-ASDR relationship indicated ongoing socioeconomic disparities. Frontier analysis showed improvement potential across growth stages. Smoking-related AMD burden decreased globally, with a correlation between national ASDRs and PM2.5 levels. Conclusions: ASDRs due to AMD have decreased over the past 32 years, while DALYs have substantially increased. The burden is more heavily tilted toward women, the elderly, and less-developed countries, with COVID-19 further intensifying the situation. Addressing the burden requires focusing on smoking cessation and air quality improvements.

PURPOSE:To investigate the effects of 0.05% Cyclosporine A (CsA) eye drops on visual quality including corneal higher-order aberrations (HOAs) in post-refractive surgery dry eye syndrome (DES) patients. METHODS:This prospective, randomized study involves 52 patients diagnosed with post-refractive surgery DES. The control group (22 eyes) received conventional dry eye therapy (20% deproteinized calf serum, 3% diquafosol tetrasodium eye drops), and the treatment group (30 eyes) received an additional 0.05% CsA. Corneal HOAs, corneal fluorescein staining (CFS), tear break-up time (TBUT), tear meniscus height (TMH), redness index, meibography, Ocular Surface Disease Index (OSDI), and subjective visual quality scores were assessed before and after three months. RESULTS:Both groups showed significant improvements (with no significant differences between groups) in TBUT, redness index, and ODSI. Compared with the control group, corneal HOAs, visual quality subjective scores, and CFS scores improved significantly in the treatment group. For the treatment group, Z(3, 1) and Z(4, -2) over 3 mm zone as well as Z(3, 1), Z(4, -2) and Z(4, -4) term over 5 mm zone showed significant changes after three months of treatment. CONCLUSION:The administration of 0.05% CsA significantly improved tear film stability and reduced corneal HOAs, enhancing visual quality in post-refractive surgery DES patients. KEY MESSAGES:What is known Post-refractive surgery dry eye syndrome (DES) can degrade visual quality due to increased higher-order aberrations (HOAs) and tear film instability. Cyclosporine A (CsA) 0.05% has recognized anti-inflammatory effects and is commonly used to manage various types of DES. What is new The addition of 0.05% CsA to conventional DES treatment significantly improves corneal HOAs and subjective visual quality in post-refractive surgery patients. This study provides quantitative evidence that CsA not only relieves post-refractive DES symptoms but also enhances visual performance through improved tear film stability and optical quality.

IntroductionGlaucoma, a leading cause of irreversible blindness, is characterized by optic neuropathy and retinopathy, with primary open-angle glaucoma (POAG) being the most prevalent form. The primary pathogenic mechanism of POAG involves elevated intraocular pressure caused by chronic fibrosis of the trabecular meshwork (TM). Autophagy, a critical process for maintaining cellular homeostasis, has been implicated in fibrosis across various organs. However, its precise role in the fibrosis associated with POAG pathogenesis remains unclear. This study investigates the involvement of autophagy in TM fibrosis and explores its potential impact on POAG development, aiming to provide insights into new therapeutic targets.MethodsTo assess autophagy activity and its relationship with fibrosis, we analyzed TM tissues from POAG patients and healthy donors. Autophagic activity in human TM tissues was measured through immunohistochemical analyses. An in vitro aging model using chronic H2O2 treatment was established to investigate the change of fibrosis in TM cells. Additionally, we used dexamethasone-treated TM cells as a POAG model to explore the role of autophagy in fibrotic progression. The involvement of the TGF-β2/Smad signaling pathway was investigated through western blot analysis and quantitative real-time PCR.ResultsThis study reveals increased autophagic activity in tissues from POAG patients and an age-related upregulation of autophagy in healthy human TM tissues. In the H2O2-induced aging model, TM cells displayed both elevated autophagic activity and fibrosis. Further investigation showed that enhanced autophagy activity promoted fibrotic progression via activation of the TGF-β2/Smad signaling pathway. Similarly, in the dexamethasone-treated TM cell model, autophagy was found to exacerbate fibrosis, aligning with observations in the aging model.DiscussionIn this study, we uncover the interplay between autophagy and the TGF-β2/Smad pathway in the pathogenesis of POAG. We observed increased autophagic activity in TM tissues from POAG patients and in TM tissues of aging healthy individuals. In human primary TM cells, we confirmed that autophagy becomes activated in the context of cellular senescence and the development of POAG, which further facilitates fibrotic progression via the TGF-β2/Smad signaling pathway. These findings underscore the important role of autophagy in POAG pathogenesis and confirm senescence as a pivotal risk factor.

To compare clinical outcomes of trifocal intraocular lens in patients with and without prior history of laser in situ keratomileusis (LASIK). A retrospective study included patients who underwent bilateral cataract surgery and PanOptix trifocal intraocular lens (IOLs) implantation. Patients were grouped: Group A for patients with history of LASIK and Group B for patients without history of LASIK. Postoperative outcome measures comprised distance, intermediate, and near visual acuity, manifest refraction, defocus curve, contrast sensitivity, visual quality, patient satisfaction, and the rate of spectacle independence. A total of 288 eyes (144 patients) were included: 132 eyes in Group A and 156 eyes in Group B. At 6 months post-surgery, patients of both groups achieved a continuous satisfying visual acuity from 33 cm to distance. 73

Purpose:To evaluate and compare the effect of femtosecond laser-assisted cataract surgery on corneal astigmatism in post-LASIK eyes and virgin eyes. Patients and Methods:Patients who underwent femtosecond laser-assisted cataract surgery were included in the study and categorized into two groups: Group A, consisting of patients with post-LASIK eyes, and Group B, consisting of patients with virgin eyes. Visual acuity, corneal astigmatism, and surgically induced astigmatism (SIA) were evaluated. Additionally, the correlation between SIA and preoperative corneal astigmatism, mean corneal curvature, and central corneal thickness was also analyzed. Results:A total of 168 eyes were enrolled in this study, with 62 eyes in Group A and 106 eyes in Group B. Significant differences in corneal astigmatism and SIA were observed between the two groups in the early postoperative period following cataract surgery (P<0.05). However, there was no significant difference at 6 months postoperatively (P>0.05). Corneal astigmatism demonstrated an against-The-rule shift in both groups postoperatively. No significant correlation was identified between SIA and preoperative corneal astigmatism, corneal curvature or corneal thickness. Additionally, there was no significant difference observed between the two groups in terms of uncorrected distance visual acuity (UDVA) at 6 months postoperatively. Conclusion:The effect of femtosecond laser-assisted cataract surgery on corneal astigmatism in post-LASIK eyes and virgin eyes was different in the early postoperative period. However, there was no significant difference at 6 months postoperatively. The post-LASIK eyes exhibited a delayed recovery compared to the virgin eyes.

CD3ζ is part of the T cell receptor (TCR)/CD3 complex that plays a critical role in antigen recognition and subsequent T cell activation. Understanding the mechanisms that regulate CD3ζ can provide new insights into the T cell-mediated immune responses. However, it is challenging to deliver exogenous genes into T cells for functional and mechanistic analyses. To this end, we established a non-T cell transfection system based on HEK293FT cells to screen for candidate regulatory proteins. The transfection was optimized using relatively high confluent cultures and the transfection reagent PolyJet™. Pervanadate (PV) treatment sustained tyrosine phosphorylation of CD3ζ, and facilitated the subsequent activation-dependent ubiquitination by E3 ligase Cbl-b in the HEK293FT system. Lck and Zap70 kinases enhanced the levels of phosphorylated CD3ζ in the presence of PV. We compared the effects of E3 ligases and the corresponding adaptor proteins on activation-dependent ubiquitination of CD3ζ in the PV-stimulated cells, and found that Cbl-b was most effective. Taken together, we have demonstrated that a non-T cell transfection system based on PV-treated HEK293FT cells could effectively mimic CD3ζ phosphorylation and ubiquitination and is a promising model for studying the role of CD3ζ signaling in T cell activation.

Purpose To evaluate the effects of clear corneal incision (CCI) location and morphology on corneal surgically induced astigmatism (SIA) and higher-order aberrations (HOAs) in patients receiving implantable collamer lens (ICL V4c) implantation.Methods This retrospective study classified right eyes that underwent ICL implantation into two groups based on temporal or superior CCI. The Pentacam HR analyzer was used to measure the corneal astigmatism and HOAs. Analysis of the clear corneal incision (CCI) morphology, including incision width (Angle-W), incision length (IL), incision angles (Angle-En/Ex), and distance from the incision to corneal apex (Dis-En/Ex), was conducted using anterior segment optical coherence tomography (AS-OCT).Results There were 75 eyes in the temporal CCI group and 47 eyes in the superior CCI group. Both groups showed satisfactory safety and efficacy postoperatively. In the temporal CCI group, Dis-En and Dis-Ex were considerably longer, whereas the superior CCI group displayed a significantly wider Angle-W. The anterior and posterior corneal SIA were comparable in both groups. Anterior corneal SIA was significantly correlated to Dis-En and Dis-Ex in the superior CCI group. Superior CCI caused a notable rise in corneal Z (3, 3), while temporal CCI led to increased Z (3, 1). CCI morphology was correlated to corneal Z (4, -4) and Z (4, 4) in the superior CCI group.Conclusion CCI locations caused slight variations in postoperative corneal SIA and HOAs following ICL implantation. Optimal postoperative visual outcomes may be better achieved with a CCI design featuring an increased distance from the corneal centroid and a decreased Angle-W.

Abstract Pterygium is a common ocular disease with a high recurrence rate, characterized by hyperplasia of subconjunctival fibrovascular tissue. Autophagy, an important process to maintain cellular homeostasis, participates in the pathogenic fibrosis of different organs. However, the exact role of autophagy in pterygium pathogenesis remains unknown. Here, we found that autophagic activity was decreased in human pterygium tissues compared with adjacent normal conjunctival tissues. The in vitro model of fibrosis was successfully established using human primary conjunctival fibroblasts (ConFB) treated with transforming growth factor-β1 (TGF-β1), evidenced by increased fibrotic level and strong proliferative and invasive capabilities. The autophagic activity was suppressed during TGF-β1- or ultraviolet-induced fibrosis of ConFB. Activating autophagy dramatically retarded the fibrotic progress of ConFB, while blocking autophagy exacerbated this process. Furthermore, SQSTM1, the main cargo receptor of selective autophagy, was found to significantly promote the fibrosis of ConFB through activating the PKCι–NF-κB signaling pathway. Knockdown of SQSTM1, PKCι, or p65 in ConFB delayed TGF-β1-induced fibrosis. Overexpression of SQSTM1 drastically abrogated the inhibitory effect of rapamycin or serum starvation on TGF-β1-induced fibrosis. Collectively, our data suggested that autophagy impairment of human ConFB facilitates fibrosis via activating the SQSTM1–PKCι–NF-κB signaling cascades. This work was contributory to elucidating the mechanism of autophagy underlying pterygium occurrence.

In the past few years, graphene-based nanocomposites are a hot topic in the fields of materials and chemistry owing to their unique features. We describe a facile melt blending method for preparing polypropylene/graphene nanocomposites in this article. The first stage involved grafting graphene onto chlorinated PP using the Friedel–Crafts reaction. The second stage involved the use of the resulting PP grafted graphene (PPG) as fillers in a melt blend with commercial PP. After being grafted with an organic PP chain, graphene becomes lipophilic; consequently, the PPG can be dispersed well within the PP matrix while retaining excellent interface adhesion. As a result, the thermostability, mechanical performance, and electrical conductivity of PP were significantly improved through the addition of PPG fillers. Additionally, with 10 wt% of PPG fillers (equivalent to 5 wt% graphene sheets), the conductivity approaches 6.8 S m−1. As a result of this research, a new method for producing high-performance PP has been developed.

Artificial intelligence (AI) technology is promising in the field of healthcare. With the developments of big data and image-based analysis, AI shows potential value in ophthalmology applications. Recently, machine learning and deep learning algorithms have made significant progress. Emerging evidence has demonstrated the capability of AI in the diagnosis and management of anterior segment diseases. In this review, we provide an overview of AI applications and potential future applications in anterior segment diseases, focusing on cornea, refractive surgery, cataract, anterior chamber angle detection, and refractive error prediction.

Secretion of melatonin, a natural hormone whose receptors are present in the ciliary epithelium, displays diurnal variation in the aqueous humor (AH), potentially contributing to the regulation of intraocular pressure. This study aimed to determine the effects of melatonin on AH secretion in porcine ciliary epithelium. The addition of 100 µM melatonin to both sides of the epithelium significantly increased the short-circuit current (Isc) by ~40%. Stromal administration alone had no effect on the Isc, but aqueous application triggered a 40% increase in Isc, similar to that of bilateral application without additive effect. Pre-treatment with niflumic acid abolished melatonin-induced Isc stimulation. More importantly, melatonin stimulated the fluid secretion across the intact ciliary epithelium by ~80% and elicited a sustained increase (~50–60%) in gap junctional permeability between pigmented ciliary epithelial (PE) cells and non-pigmented ciliary epithelial (NPE) cells. The expression of MT3 receptor was found to be >10-fold higher than that of MT1 and MT2 in porcine ciliary epithelium. Aqueous pre-treatment with MT1/MT2 antagonist luzindole failed to inhibit the melatonin-induced Isc response, while MT3 antagonist prazosin pre-treatment abolished the Isc stimulation. We conclude that melatonin facilitates Cl− and fluid movement from PE to NPE cells, thereby stimulating AH secretion via NPE-cell MT3 receptors.

AIM: To report the safety, efficacy, and accuracy of small-incision lenticule extraction (SMILE) or femtosecond-assisted laser in situ keratomileusis (FS-LASIK) for the correction of myopia or myopic astigmatism in patients with deep corneal opacity denoted by anterior segment optical coherence tomography (AS-OCT). METHODS: Four patients with monocular corneal opacity (3 due to mechanical injury, 1 due to a firecracker wound) were recruited and treated with refractive surgery (3 for SMILE, 1 for FS-LASIK combined with limbal relaxing incision (LRI). Preoperative ocular manifestations, surgical details, postoperative visual outcomes, corneal opacity parameters, and corneal topography were analyzed. RESULTS: Preoperatively, spherical diopter ranged from -3.0 D to -4.75 D with cylinder ranging from -0.75 to -5.0 D, and corrected distance visual acuity (CDVA) ranging from 20/25 to 20/20. One eye’s corneal opacity was located in the central zone and three were in the mid-peripheral optical zone. Three patients underwent uneventful SMILE in both eyes, whilst one patient underwent FS-LASIK for high astigmatism in both eyes and LRI in the right eye. CDVA of the eye with corneal opacity ranged from 20/22 to 20/20 one to six weeks postoperatively. Two patients achieved better CDVA and no patients lost Snellen lines. The postoperative diopter was within ±0.75 D for all eyes. Significant edema existed above the corneal opacity in one eye and dissipated soon. No eccentric corneal topography or morphological anomaly of the corneal cap or flap was observed. CONCLUSION: The cases demonstrate that SMILE or FS-LASIK is safe and effective to treat myopic astigmatism combined with deep corneal opacity lesions after comprehensive preoperative evaluation and appropriate candidate selection. FS-LASIK combined with LRI is also sufficient for correcting high astigmatism due to corneal scarring.

At present, corneal refractive surgery is mainly divided into three categories: superficial corneal refractive surgery, lamellar corneal refractive surgery and femtosecond laser lens extraction, all of which are widely used in the correction of refractive errors. Although most patients obtain ideal uncorrected distance visual acuity after surgery, the increase of higher-order aberrations often leads to complications such as glare, ghosting, and decreased night vision. There are many factors that influence higher-order aberrations in corneal refractive surgery. This review summarized the types of corneal refractive surgery and the influencing factors of higher-order aberrations during corneal refractive surgery including corneal flap/cap, degree of correction, optical zone diameter, optical zone eccentricity, and different excimer laser ablation modes.

Uveitis is a common ocular disease and may cause serious damage of visual function. The pathogenesis of uveitis is closely related to its autoimmune response. The Th1 cells and Th17 cells were identified to play a key role in the occurrence of autoimmune uveitis and experimental autoimmune uveitis, whilst the Th17 cells were found to be closely associated with disease recurrence. The regulatory T cells (Tregs) were found to be involved in the regression of inflammation. The dysfunction and ratio of Tregs were the major causes for persistence and recurrence of uveitis. Th17 cells and Tregs can also interconvert with each other under certain conditions. Regulating the Th17/Tregs balance might be a potential novel approach to alleviating inflammation and hence providing the treatment for uveitis.

铁死亡是近年发现的一种新型细胞死亡方式,与过去已知细胞死亡方式有明显差异.铁死亡的机制为在细胞铁过载基础上发生的谷胱甘肽过氧化物酶(GPX)失活和细胞内致死性脂质过氧化物累积,电镜下可以观察到细胞膜破裂,线粒体嵴减少,线粒体外膜皱缩破裂等变化.目前研究发现眼科许多疾病涉及氧化还原稳态破坏、GPX失活、铁代谢紊乱、脂质过氧化物累积等铁死亡相关过程,提示铁死亡在常见眼科疾病中发挥了重要作用.本文主要围绕铁死亡机制以及铁死亡在角膜损伤、白内障、青光眼、年龄相关性黄斑变性和糖尿病视网膜病变中的作用进行综述,有助于进一步梳理常见眼科疾病的病理机制,加深对眼科疾病的理解,为眼科疾病的防治提供新思路.
