Objective:To observe the changes of macular microvessels in patients with retinal vein occlusion (RVO) and macular edema (ME) after intravitreal injection of aflibercept (IVA), and analyze its correlation with best corrected visual acuity (BCVA).Methods:A retrospective case study. Thirty patients (30 eyes) with monocular RVO with ME (RVO-ME) who were diagnosed in the clinical examination of Tianjin Eye Hospital from April 2019 to February 2020 were included in the study. Among them, there were 12 males (12 eyes) and 18 females(18 eyes); the average age was 54.30±13.17 years. The average course of disease was3.43±1.97 months. Both eyes were examined by BCVA and optical coherence tomography (OCTA). The on-demand injection was adopted after the first injection in IVA treatment regimen. The macular area 6 mm×6 mm in both eyes was scanned with an OCTA instrument, and the area of the foveal avascular area (FAZ), FAZ circumference (PERIM), and out-of-roundness were measured at baseline and 1, 3, and 6 months after treatment. Index (AI), blood flow density within 300 μm width of FAZ (FD-300), foveal retinal thickness (CMT), superficial retinal capillary plexus (SCP), deep retinal capillary plexus (DCP) blood flow density. The paired t test was used to compare the quantitative parameters of the affected eye and the contralateral healthy eye at baseline; the changes of the quantitative parameters at baseline and 1, 3, and 6 months after treatment were analyzed by repeated measures analysis of variance. Pearson correlation analysis was used to analyze the correlation between BCVA, retinal perfusion, and macular blood supply parameters at 6 months after IVA treatment. Results:At baseline, compared with the contralateral healthy eye, the FAZ area ( t=-4.091), PERIM ( t=-5.098) and AI ( t=-9.093) of the RVO-ME eye were enlarged, and FD-300 ( t=7.237) and overall SCP and DCP blood flow density ( t=8.735, 9.897) decreased, the difference was statistically significant ( P<0.001). Six months after treatment, the BCVA of RVO-ME eyes was significantly increased, CMT decreased, FAZ area expanded, and AI decreased ( t=8.566, 16.739, -6.469, 9.719; P<0.001), the difference was statistically significant. There was no significant change in the blood flow density of FD-300 and overall SCP and DCP, and the difference was not statistically significant ( t=1.017, 1.197, 0.987; P>0.05). Compared with baseline, the FAZ area of RVO-ME eyes gradually expanded at 3 and 6 months after treatment, and the difference was statistically significant ( F=21.979, P<0.001). Correlation analysis results showed that BCVA at 6 months after treatment was positively correlated with the overall SCP and DCP blood flow density at baseline and 6 months after treatment ( r=-0.538, -0.484, -0.879, -0.854; P<0.05). There was a negative correlation with the area of FAZ 6 months after treatment ( r=0.544, P=0.001). The number of ME recurrences was negatively correlated with BCVA and overall SCP and DCP blood flow density 6 months after treatment ( r=0.604, -0.462, -0.528; P<0.05), it was positively correlated with FAZ area ( r=0.379, P=0.043). Conclusion:Within 6 months of IVA treatment in RVO-ME eyes, ME is significantly reduced and visual acuity is improved; SCP blood flow density decreases, and FAZ area expands.
Objective:To observe the outcome of posterior staphyloma (PS) marginal retinal photocoagulation in pars plana vitrectomy (PPV) for high myopia macular hole retinal detachment eyes accompanied with PS.Methods:From January 2017 to June 2019, 49 patients (49 eyes) with high myopia macular hole retinal detachment accompanied with PS who were undergone PPV operation from Tianjin Eye Hospital were included in this study. There were 13 males (13 eyes) and 36 females (36 eyes). All patients underwent best corrected visual acuities (BCVA) and optical coherence tomography examinations. The standard logarithmic visual acuity chart was used for BCVA examination, and the visual acuity was converted to minimum resolution angle in logarithmic (logMAR) when recorded. The patients were randomly divided into two groups according to surgical options: conventional PPV with internal limiting membrane (ILM) peeling (group A, 24 eyes), PS marginal retinal photocoagulation in PPV with ILM peeling (group A, 25 eyes). The mean preoperative logMAR BCVA of group A and B were 1.87±0.28 and 1.80±0.37, the difference was not statistically significant ( t=0.604, P=0.551). The patients in the group A received 23G PPV, triamcinolone acetonide staining during the operation, the epiretinal membrane was peeled off, indocyanine green assisted staining, the posterior macular ILM was peeled off, and the peripheral retina was examined in detail during the operation. Areas with retinal degeneration were reinforced by laser photocoagulation, and the subretinal fluid was drained through the macular hole and filled with silicone oil. The eyes of the group B were subjected to retinal photocoagulation for 2 to 3 rows at the edge of the PS in addition to the usual surgical procedures. The average follow-up time was 8.34±3.21 months. Surgical outcome were estimated by the average number of operation, retinal reattachment rate, macular hole closure rate and BCVA. The χ2 test or Fisher exact probability was used to compare the count data. Independent sample t test was used to compare the measurement data. Results:Retinal reattachment was obtained in 17 eyes (70.8%, 17/24) and 24 eyes (96.0%, 24/25) in group A and B after first surgery respectively, the difference was statistically significant ( χ2=3.984, P=0.046). Final retinal reattachment was obtained in all 49 eyes. Final macular hole closure was in 15 eyes (62.5%, 15/24) and 19 eyes (76.0%, 19/25) in group A and B, respectively, the difference was not statistically significant ( χ2=1.051, P=0.305). The mean postoperative logMAR BCVA of group A (1.20±0.47) and B (1.08±0.39) were all improved than preoperative BCVA, the differences were all statistically significant ( t=2.899, 5.327; P=0.001, 0.000), the differences of mean postoperative logMAR BCVA between two groups was not statistically significant ( t=0.675, P=0.506). The mean number of operation of group A (2.63±0.88) was more than group B (2.08±0.28), the difference was statistically significant ( t=3.003, P=0.006). Conclusion:In comparison with conventional PPV, combined PS marginal retinal photocoagulation can improve retinal reattachment rate after first surgery, and reduce the number of reoperations.
