Background:This systematic review and meta-analysis aimed to compare outcomes of 0.01% atropine with orthokeratology (AOK) vs. orthokeratology (OK) alone for slowing the progression of myopia in children. Methods:MEDLINE via PubMed, Embase, Scopus, Web of Science, CENTRAL (Cochrane Central Register of Controlled Trials), Chinese electronic databases of VIP, and Wanfang were searched from inception until 19th August 2024 for randomized controlled trials (RCTs) about the review topic. The primary outcome was a change in axial length (AL) (mm). Secondary outcomes were spherical equivalent refraction (SER) (Diopter), pupil diameter (PD) (mm), amplitude of accommodation (AA) (Diopter), and intraocular pressure (IOP) (mmHg). Results:10 articles corresponding to eight RCTs were included. Meta-analysis found that change in AL was significantly reduced with AOK as compared to OK alone at 6 months (MD: -0.10 95% CI: -0.14, -0.06 I2 = 48%), 12 months (MD: -0.08 95% CI: -0.10, -0.07 I2 = 0%) and 24 months (MD: -0.14 95% CI: -0.19, -0.08 I2 = 0%). Pooled analysis found that AOK did not reduce the progression of SER (MD: 0.06 95% CI: -0.00, 0.12 I2 = 7%) and increased PD (MD: 0.63 95% CI: 0.40, 0.85 I2 = 86%) as compared to OK alone. Pooled analysis also found a tendency of reduced AA with AOK as compared to OK alone but without significant results (MD: -0.45 95% CI: -1.00, 0.10 I2 = 59%). Meta-analysis failed to show a statistically significant difference in change of IOP between AOK and OK (MD: -0.49 95% CI: -1.48, 0.50 I2 = 51%). Conclusions:AOK seems to be more efficacious in slowing the progression of myopia in children as compared to OK alone.

Background & Objective:Several diabetic macular edema (DME) patients are resistant to anti-vascular endothelial growth factors (VEGF) injections and are treated with corticosteroid implants. Dexamethasone implants (DEXI) are popular, but fluocinolone acetonide implants (FACI) are being used as third-line DME therapy, given their convenience and prolonged action. The efficacy of FACI in patients previously treated with DEXI remains understudied. We collated evidence from single-arm studies examining the efficacy and safety of FACI in DME patients treated with DEXI. Methodology:We explored the websites of Embase, PubMed, PubMed CENTRAL, Web of Science, and Scopus up to January 15, 2025. Pre and post-FACI best-corrected visual acuity (BCVA), central retinal thickness (CRT), and intraocular pressure (IOP) were compared. Results:Eight studies with 365 eyes were included. Meta-analysis showed that use of FACI was associated with statistically significant improvement in BCVA (letters) at three months (MD: 5.40 95% CI: 0.13, 10.67 I2= 78%) but not at six months (MD: 5.43 95% CI: 1.79, 12.64 I2=86%), and 12 months (MD: 3.39 95% CI: 3.12, 9.91 I>2=84%). The pooled analysis indicated a statistically significant reduction in CRT after administration of FACI at 3 months (MD: 118.11 95% CI: 211.62, -24.61 I2=93%), six months (MD: 121.79 95% CI: 212.35, -31.24 I2=94%), and 12 months (MD: 108.33 95% CI: 175.47, -41.2 I2=92%). No significant change in IOP was noted at all follow-up intervals. Conclusions:Use of FACI in patients previously treated with DEXI results in anatomical improvement but may be associated with limited visual gain. The use of FACI seems safe without significant change in IOP. Registration: PROSPERO CRD42025635691.

特发性黄斑前膜(IERM)为不明原因的黄斑区视网膜前无血管纤维组织膜形成,对视网膜存在切线及前后方向的牵拉力,能引起视网膜组织扭曲、增厚,是一种临床上常见的导致视力下降及视物变形的黄斑部疾病[1].目前IERM尚无有效的药物治疗,手术剥膜仍是唯一有效的治疗方法.大多数术者习惯性玻璃体腔填充气体,配合患者俯卧位,可以有效顶压眼球后极部,从而有利于减轻黄斑水肿,改善患者的视力[2].但对于高龄、肥胖及基础疾病等全身因素患者,增加了术后俯卧位的风险,给患者的工作、生活带来极大的不便[3].相对于气体填充,平衡液填充不需要俯卧位,对于部分不能耐受俯卧的患者非常有利,但缺少气体的顶压效果,目前是否需要气体填充仍存在争议[4].本研究旨在比较玻璃体切除术联合消毒空气或平衡液填充治疗IERM的疗效,报道如下.

BACKGROUND:Myopic foveoschisis (MF) is a common complication of pathological myopia. A macular hole (MH) usually results from the natural progression of MF and is a common complication of vitrectomy. Vitrectomy combined with residual internal limiting membrane (ILM) covering and autologous blood was effective for closing a secondary MH.CASE SUMMARY:A 52-year-old woman presented to our clinic with a complaint of blurred vision in the right eye for 7 years. Her best corrected visual acuity (BCVA) was 20/100, axial length was 25.79 mm and standard equivalent refractive error was -10.5 dioptres. Preoperative optical coherence tomography revealed foveoschisis in the right eye. Vitrectomy with fovea-sparing ILM peeling was performed. An MH developed and gradually expanded 5 mo after the initial vitrectomy. Vitrectomy with residual ILM covering and autologous blood was performed. The MH closed 3 wk after the second vitrectomy.CONCLUSION:Fovea-sparing ILM peeling can provide residual ILM for the treatment of MH secondary to vitrectomy for MF. Vitrectomy combined with residual ILM covering and autologous blood is effective for closing secondary MH and improving BCVA.

BACKGROUND AND OBJECTIVE:Femtosecond laser-assisted cataract surgery (FLACS) is rapidly gaining popularity due to the improved consistency and predictability for capsulorhexis. This study aimed to investigate the preliminary clinical outcomes of FLACS with a noncontact femtosecond laser system.PATIENTS AND METHODS:This prospective study enrolled 25 eyes in the trial group underwent FLACS (LLS-fs 3D, LENSAR, USA), and 29 eyes in the control group underwent conventional cataract surgery (Stellaris, Bausch & Lomb, USA). The phacoemulsification time, energy, and complications during operation were recorded. Postoperative refraction at 1 day, 1 week, 1 and 3 months, the capsulorhexis size and corneal endothelial density at 1 and 3 months were also measured.RESULTS:Compared to the control group, reduction in phacoemulsification time was 51.5% (P = 0.02), and in overall energy, 65.1% (P = 0.02) in the trial group. In the trial group and the control group, total time of cataract procedure was 10.04 ± 1.37 minutes, 10.52 ± 1.92 minutes, respectively (P = 0.31); the absolute difference between attempted and achieved capsulorhexis diameter at 1 month was 192.9 ± 212.0 µm, 626.9 ± 656.6 µm, respectively (P = 0.04), and at 3 months, 256.6 ± 181.9 µm, 572.1 ± 337.0 µm, respectively (P= 0.03); the absolute difference between attempted and achieved spherical equivalent at 3 months was 0.16 ± 0.16 D, 0.74 ± 0.65 D, respectively (P < 0.01); mean corneal endothelial cell loss at 1 month was 15.6% and 14.2%, respectively (P = 0.77), and at 3 months, 2.9%, 4.2%, respectively (P = 0.50).CONCLUSIONS:With the noncontact femtosecond laser system, FLACS can significantly improve the accuracy and repeatability of capsulorhexis, reduce the phacoemulsification time and overall energy, and enhance the predictability and stability of postoperative refraction.
