Purpose: To determine whether the presenting clinical features of active myopic choroidal neovascularization (CNV), including the presence of fibrosis or atrophy, limit the ultimate visual acuity gains from intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy. Methods: A retrospective analysis of 42 eyes with new-onset subfoveal CNV was performed. Only patients without concurrent age-related macular degeneration and with a spherical equivalent of at least −6.0 diopters were included in the study. All eyes received either intravitreal ranibizumab or bevacizumab injections as the primary treatment on a pro re nata basis for 1 year. Changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were recorded. Results: The mean number of ranibizumab (18 eyes) or bevacizumab (24 eyes) injections was 4.7 ± 0.5 over a mean follow-up time of 12 ± 0.4 months. The mean age of the patients was 62 ± 2.0 years. Based on optical coherence tomography staging at the initiation of treatment for active CNV, 30 had no fibrosis or atrophy (group 1), 5 had fibrotic stage, and 7 had atrophic stage CNV (the latter combined to form group 2). The BCVA for group 1 improved significantly ( P < .02) but worsened for group 2 ( P < .38), a statistically significant difference ( P < .05). The CRT for group 1 also declined significantly more than for group 2 ( P < .014). Conclusion: The presence of fibrosis or atrophy in eyes with active myopic CNV at the initiation of anti-VEGF therapy was associated with limited anatomic outcomes and visual gain.

Abstract Background To compare the outcome of vitrectomy, subretinal tissue plasminogen activator (TPA), and gas with and without subretinal air versus Intravitreal TPA and gas in the treatment of sub macular haemorrhage (SMH) due to Neovascular age related macular degeneration Methods We analysed the notes of 29 cases presented with SMH in the period between 01/2016 and 09/2018 in James Cook University Hospital. Presenting visual acuity (BCVA), size and location of SMH, Procedure done, final BCVA at 6 months and any surgical complications were recorded. 11 Cases (Group 1) received intravitreal TPA (50ug in 0.1 ML), 0.3 ml of pure SF6. 18 cases (Group 2) received 23 G Pars Plana vitrectomy, Subretinal TPA injection (25ug in 0.1 ml), and 20% SF6 gas filling. Group 2 was further divided into 2A (10 patients) who received only subretinal TPA and group 2B (8 patients) who received additional 0.1 ml subretinal air.Results The mean BCVA at presentation was 0.0068 in group 1 and 0.0067 in group 2 (p= 0.8734). The mean postoperative BCVA at six months was 0.31 in group 1 and 0.58 in group 2 (p=0.0015). Subgroup analysis of group 2 didn’t show statistically significant difference in outcome when adding subretinal air to the vitrectomy procedure (p=0.7009).Conclusion Vitrectomy, gas and subretinal TPA has more successful displacement rate and better visual outcome than Intravitreal TPA & Gas alone in treating SMH involving the fovea in AMD. Additional subretinal air doesn't seem to improve the outcome in cases having vitrectcomy.

Aim: to assess the effectiveness and tolerability of anti-VEGF agents, aflibercept (2.0 mg) and ranibizumab (0.5 mg), in the combined treat-ment for wet age-related macular degeneration (AMD) in routine clinical practice.Patients and Methods: 55 patients (65 eyes) with the late stage of wet AMD were divided into two groups. Group 1 included 32 eyes with classic choroidal neovascularization (CNV) and group 2 included 33 eyes with occult CNV. Best-corrected visual acuity (BCVA), intraocular pressure, and retinal nerve fiber layer (RNFL) thickness were measured. These parameters were compared at different time points during the treatment.Results: overall AMD duration (January 2019) was 36 (19; 47) months being 30 (12; 44) months in group 1 and 36 (23; 48) months in group 2 (р>0.05). The first intravitreal administration of an anti-VEGF drug was performed 7.5 (3.5; 9.5) months after AMD diagnosis in group 1 and 7 (3; 11) months after AMD diagnosis in group 2. Significant differences in intragroup intervals were revealed between various follow-up periods. More differences were identified for the intervals between intravitreal administrations in group 2. Baseline and final BCVA during the entire follow-up which was 29.5 (19.5; 38) months in group 1 and 28 (25; 44) months in group 2 demonstrated neither intragroup nor intergroup differences (р>0.05). Conclusion: our management strategy for wet AMD is somewhat different from conventional guidelines. However, it has no significant impact on visual acuity during the follow-up.Keywords: age-related macular degeneration, anti-VEGF drugs, intravitreal administration, IOP level, aflibercept, ranibizumab.For citation: Kuroyedov A.V., Gapon’ko O.V., Gorodnichiy V.V. et al.

Purpose: To report the clinical outcomes of intravitreal aflibercept therapy in eyes with refractory and recurrent neovascular age-related macular degeneration (AMD) switched from intravitreal bevacizumab or ranibizumab. Methods: This is a retrospective review of eyes with neovascular AMD switched to intravitreal aflibercept with at least 1 year of follow-up after the switch. All patients had had a minimum of 3 injections of bevacizumab or ranibizumab before the switch. Aflibercept was used in patients considered refractory to bevacizumab (group 1) and in recurrent patients on therapy with ranibizumab due to an institutional policy decision (group 2). Changes in best-corrected visual acuity, fluid on optical coherence tomography (OCT), central retinal thickness (CRT) and the frequency of injections were compared. Results: Eighty-five eyes of 69 patients were analyzed, 39 eyes in group 1 and 46 in group 2. The mean follow-up time was 31.6 months prior to the switch and 14.7 months on treatment with aflibercept. One year after the switch, there was a nonsignificant mean decrease of 2 letters in visual acuity in both groups (group 1: from 58.2 to 55.8 letters, p = 0.086; group 2: from 56.4 to 54.5 letters, p = 0.168), but the mean number of injections per month was significantly lower (from 0.76 to 0.57, p < 0.001). With the switch, 90.6% of the patients showed anatomic improvement with a reduction of fluid on OCT, and both groups presented significant improvement in CRT (group 1: 65.3 µm, p = 0.051; group 2: 91.0 µm, p < 0.001). Conclusion: Aflibercept appears to be a valuable tool for the management of patients with poor responses to other anti-vascular endothelial growth factor drugs. These patients could have anatomic improvement, and the injection intervals could be extended.

Conclusion: Vitrectomy, gas and subretinal TPA has more successful displacement rate and better visual outcome than Intravitreal TPA & Gas alone in treating SMH involving the fovea in age-related macular degeneration. Additional subretinal air doesn’t seem to improve the outcome in cases having vitrectomy.

Abstract Aim of the Work The aim of this work is to compare the response of treatment with ranibizumab in terms of visual acuity in cases of CNV secondary to pathological myopia versus CNV secondary to age-related macular degeneration. Methods This prospective, comparative study included ten eyes newly diagnosed as having CNV secondary to pathological myopia, and 10 eyes newly diagnosed as having subfoveal active CNV secondary to AMD. All patients had 3 monthly intravitreal Injections of 0.50 mg (in 0.05 ml of solution) ranibizumab with monthly evaluation of best corrected visual acuity (BCVA) by Landolt C chart, and also calculated in Logarithm of Minimum Angle of Resolution (Log MAR). Results pretreatment there was no significant difference between the two groups as the mean VA (Log Mar) was 1.31 ± 0.2 in AMD group and 1.17 ± 0.3 in MCNV group of P value = 0.431 and also post three IVI of ranibizumab showed no significant difference between the two groups as the mean VA (Log Mar) was 1.22 ± 0.2 for AMD and 1.22 ± 0.5 for MCNV of P value = 0.635. Conclusion there was no significant difference in BCVA between AMD and MCNV groups after three intravitreal injections of ranibizumab.

Aim: To compare surgical parameters and visual outcomes of coaxial microincision cataract surgery (MICS) with standard phacoemulsification. Methods: A prospective randomized study was conducted on 60 eyes of 60 patients with age-related uncomplicated cataract who underwent: standard phacoemulsification surgery (30 eyes) i.e., Group 1, or coaxial MICS (30 eyes) i.e., Group 2. Intraoperative parameters were mean effective phacoemulsification power (EPP), effective phacoemulsification time (EPT), and total volume of balanced salt solution (BSS) used. Best-corrected visual acuity (BCVA) and surgically induced astigmatism (SIA) were evaluated pre- and postoperatively. Results: Mean BCVA at 6 weeks was 0.04 ± 0.07 in Group 1 and 0.05 ± 0.08 in Group 2. No significant difference was observed in SIA between the two groups. Mean EPT was 29.80 ± 3.67 seconds in Group 1 and 31.93 ± 4.08 seconds in Group 2. The mean total EPP in Group 1 was 35.77 ± 5.17%, whereas it was 33.70 ± 3.05% in Group 2. There was a significant statistical difference between mean EPP and EPT in the two groups. Mean total BSS volume used in Group 1 was 128.83 ± 19.81 ml, whereas it was 139.33 ± 13.57 ml in Group 2. Conclusion: Although EPT and BSS volume used were significantly higher in coaxial MICS, the postoperative results of the two techniques were comparable.

Previous studies based on clinical trial data have demonstrated that greater fluctuations in retinal thickness during the course of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (nAMD) is associated with poorer visual acuity outcomes. However, it was unclear whether similar findings would be observed in real-world clinical settings. This study aimed to evaluate the association between retinal thickness variability and visual outcomes in eyes receiving anti-VEGF therapy for nAMD using pro re nata treatment regimen. A total of 64 eyes which received intravitreal anti-VEGF therapy (bevacizumab, ranibizumab or aflibercept) for the treatment of nAMD were evaluated. Variability in spectral-domain optical coherence tomography (OCT) central subfield thickness (CST) was calculated from the standard deviation (SD) values of all follow-up visits after three loading doses from month 3 to month 24. Eyes were divided into quartiles based on the OCT CST variability values and the mean best-corrected visual acuity values at 2 years were compared. At baseline, the mean ± SD logMAR visual acuity and CST were 0.59 ± 0.39 and 364 ± 113 µm, respectively. A significant correlation was found between CST variability and visual acuity at 2 years (Spearman’s ρ = 0.54, p < 0.0001), indicating that eyes with lower CST variability had better visual acuity at 2 years. Eyes with the least CST variability were associated with the highest mean visual acuity improvement at 2 years (quartile 1: +9.7 letters, quartile 2: +1.1 letters, quartile 3: −2.5 letters, quartile 4: −9.5 letters; p = 0.018). No significant difference in the number of anti-VEGF injections was found between the four CST variability quartile groups (p = 0.21). These findings showed that eyes undergoing anti-VEGF therapy for nAMD with more stable OCT CST variability during the follow-up period were associated with better visual outcomes. Clinicians should consider adopting treatment strategies to reduce CST variability during the treatment course for nAMD.

Purpose. Intravitreal antivascular endothelial growth factor (anti-VEGF) therapy has been widely used for the treatment of neovascularization (NV) secondary to age-related macular degeneration (AMD). This study aimed to compare the efficacy among different subtypes of neovascular age-related macular degeneration (nAMD). Methods. PubMed, Embase, and the Cochrane Library were searched for eligible studies. We performed meta-analysis using Review Manager 5.3 and Stata/SE 12.0. Results. A total of 24 studies met our inclusion criteria and were included in the systematic review. At 3 months, the mean logarithm of the minimum angle of resolution (logMAR) improvements were −0.09, −0.18, and −0.23 for type 1, 2, and 3, respectively, while the mean macular thickness (MT) changes were −104.83, −130.76, and −196.29 μm. At 12 months, the mean changes in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters were 6.38, 8.12, and 9.37, while the MT decrease was 126.51, 126.52, and 139.85 μm, respectively. However, statistically significant difference was only found between type 1 and 3 in vision improvement, both in the short term (p=0.0002) and long term (p=0.01). Conclusions. The reactivity to VEGF inhibitors varied among different subtypes of nAMD. The efficacy of intravitreal anti-VEGF therapy in type 3 nAMD was statistically better than type 1 when considering vision improvement at 3 and 12 months. Thus, the lesion subtype is a predictor for the treatment outcome which can help guide prognosis.

Purpose To evaluate the efficacy of intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents for treatment of neovascular age-related macular degeneration (nAMD) in vitrectomized eyes. Methods The medical records were reviewed of nAMD patients treated with anti-VEGF agents who previously underwent pars plana vitrectomy (PPV). PPV was performed with complete posterior vitreous detachment induction. Results A total of 44 eyes from 44 patients were included. The mean central foveal thickness (CFT) was 478.50 ± 156.93 μm at baseline, 414.25 ± 143.55 μm (86.6% of baseline) at 1 month after first injection (P < 0.001), and 386.75 ± 141.45 μm (80.8% of baseline) after monthly multiple injections (2.30 ± 1.07; range, 1–5) (P < 0.001). The mean logarithm of the minimum angle of resolution best-corrected visual acuity visual acuity (BCVA) was 0.85 ± 0.57 at baseline, 0.86 ± 0.63 after the first injection, and 0.84 ± 0.64 after monthly multiple injections. BCVA improved in 39.5% at 1 month after first injection and 45.2% at 1 month after monthly multiple injections. In the subgroup analysis, CFT of eyes with the posterior capsule decreased significantly to 85.8% and 79.8% of baseline values at 1 month after the first injection and after monthly multiple injections, respectively. CFT of eyes without the posterior capsule decreased to 91.6% and 87.4% of baseline values at 1 month after the first injection and after monthly multiple injections, respectively, without statistical significance. Conclusion Monthly injections of Intravitreal anti-VEGF agents induced favorable anatomical improvement and vision maintenance in vitrectomized eyes with nAMD.

Design: prospective non-randomized experimental longitudinal cohort study. The aim of the study: to evaluate the visual acuity after phacoemulsification in patients with the “wet” form of age-related macular degeneration, treated by intravitreal angiogenesis inhibitor injections. Materials: 48 patients (48 eyes) with the “wet” form of AMD, treated by intravitreal angiogenesis inhibitor injections, and incipient cataract. All eyes in the study had a diagnosis of “wet” AMD and underwent cataract surgery. They were followed for a minimum of two years after the cataract surgery. The mean age of patients was 78.16 ± 5 years. There were 36 female (75 %) and 12 male (25 %) patients. Results: All patients were retrospectively divided into two groups. Group No. 1 consisted of 23 patients — operated within a year of the diagnosis of “wet” AMD, and group No. 2 which consisted of 25 patients who had a diagnosis of “wet” AMD for longer than one year prior to the cataract surgery. The mean preoperative visual acuity in the 1st group was 0.16 ± 0.07 (median 0.15), and in patients of group 2 — 0.23 ± 0.06 (median 0,2). Mean visual acuity immediately before surgery in the 1st group was 0.13 ± 0.04 (median 0.09), in the 2nd group — 0.12 ± 0.04 (median 0,08). After surgery, in the 1st group, mean visual acuity was — 0.28 ± 0.08 (median 0.25), in the 2nd group —0.18 ± 0.07 (median 0,15). The difference between the two groups was statistically significant, p < 0.01, t-test. Statistically significant visual acuity increase after surgery was registered in both groups and was preserved after one and two years, when compared to the data before surgery: for the 1st group — 0.13 and 0.1; for the 2nd group — 0,1 and 0.07, respectively (p < 0,01, Wilcoxon criterion). Conclusions: Phacoemulsification is reasonable for eyes with the “wet” form of age-related macular degeneration. Patients with shorter “wet” AMD duration obtain a higher visual acuity increase after cataract surgery. Statistically significant visual acuity increase after surgery is preserved in the majority of patients during next 2 years of follow-up.
