AIM: To assess the choroidal structural alterations after intravitreal injection of aflibercept in neovascular age-related macular degeneration (nAMD). METHODS: Fifty eyes with treatment-naïve nAMD were evaluated at baseline, 3rd, and 12th month. Fifty eyes of 50 healthy subjects were also included as controls. Choroidal thickness (CT) was measured in the subfoveal region. Total circumscribed choroidal area (CA), luminal area (LA), stromal area (SA), and choroidal vascularity index (CVI) was calculated using Image J. RESULTS: At baseline, subfoveal CT was increased in nAMD patients compared to controls (P=0.321). Eyes with nAMD had a significantly increased total circumscribed CA and SA (P=0.041, 0.005, respectively). The CVI was decreased (P=0.038). In the 3rd month, the subfoveal CT, LA, and CVI revealed a decrease (P=0.005, P=0.039, 0.043, respectively). In the 12th month, subfoveal CT, LA, and CVI were decreased in comparison to baseline measures (P<0.001, 0.006, 0.010, respectively). CONCLUSION: Significant structural alterations are found after intravitreal aflibercept treatment during the 12-month follow-up, in particular at the third month, in eyes with nAMD.

Purpose: To report the visual and anatomic outcomes in treatment-naïve neovascular age-related macular degeneration (nAMD) patients treated with aflibercept under a standardized Treat and Extend (T&E) protocol for up to 3 years of follow-up in “real-life” practice. Methods: This retrospective, observational, multicenter study included patients with treatment-naïve nAMD and at least 12 months of follow-up. T&E regimen adjustment was initiated after loading phase. At each visit best-corrected visual acuity (BCVA) and optical coherence tomography parameters were performed. Results: One hundred and thirty-six eyes of 115patients had at least 1 year of follow-up with 114 and 82 eyes completing at least 2 and 3 years of follow-up, respectively (mean follow-up duration: 2.7 ± 1.3 years). Mean age was 78.6 ± 8.6 years old and 52% were women. Mean BCVA increased from 60.6 ± 18.7 letters at diagnosis to 66.9 ± 16.2 letters at 1 year (+6.3 letters, p = 0.003) and remained stable throughout the follow-up period (63.1 ± 20.3 letters (+2.5, p = 0.1) and 64.0 ± 20.1 letters (+3.4, p = 0.27) at 2 and 3 years, respectively). The mean central retinal thickness decreased significantly from 358.2 ± 87.9 µm at baseline to 302 ± 71.7 µm at 12 months and maintained stable after 36 months of follow-up (297.1 ± 76 µm, p < 0.0001). Mean number of injections was 6.6 ± 2.2, 4.8 ± 1.9, and 5.6 ± 1.7 at 1, 2, and 3 years, respectively. Mean cumulative number of 16.4 ± 5.6 injections after 3 years. Mean treatment interval was 6.8 ± 2.5 weeks at 1 year. Eight-week and 12-week treatment interval were achieved in 59.5% and 19.1%, 65.8%, and 36.8% and 69.5% and 41.5% at 1, 2, and 3 years, respectively. Conclusions: Our study demonstrated that intravitreal injections of aflibercept initiated under a standardized T&E for patients with treatment-naïve nAMD allow for significant visual improvement at 12 months, which was maintained over a 3-year follow-up period.

AimTo report long-term outcomes on best-corrected visual acuity (BCVA) and treatment intervals with a treat-and-extend (T&E) regimen in patients with neovascular age-related macular degeneration (nAMD).MethodsThis observational study included treatment-naïve patients with nAMD, treated with aflibercept. A specific T&E protocol without a loading phase and predefined exit criteria was administered. After reaching predefined ‘exit-criteria’, the treatment period was complete, and patients were observed three monthly.ResultsEighty-two patients with a follow-up period of ≥2 years were included. BCVA (mean±SD, ETDRS letters) increased from 51.9±25.2 at baseline to 63.7±17.7 (p<0.0001) at 1 year, 61.7±18.5 (p<0.0001) at 2 years, 62.4±19.5 (p<0.0001, n=61) at 3 years and remained insignificantly higher than baseline at 4 years at 58.5±24.3 (p=0.22). Central subfield thickness (mean±SD, μm) decreased significantly from 387.5±107.6 (p<0.0001) at baseline to 291.9±65.5 (p<0.0001) at 1 year, and remained significantly lower until 4 years at 289.0±59.4 (p<0.0001). Treatment intervals (mean±SD, weeks) could be extended up to 9.3±3.1 weeks at 1 year and remained at 11.2±3.5 weeks at 4 years. Twenty-nine (35%) patients reached exit criteria and continued with three monthly observation only.ConclusionsAfter 4 years of treatment, initial vision gains were maintained with a reasonable treatment burden, even without an initial loading phase. Our results on functional outcomes are comparable with large controlled studies.

Purpose. To evaluate the clinical characteristics and long-term prognosis of pachychoroid neovasculopathy (PCN) when compared with type 1 neovascular age-related macular degeneration (nAMD). Methods. We retrospectively analyzed 30 and 60 patients whose eyes were diagnosed as treatment-naïve PCN or type 1 nAMD, respectively. All subjects were followed up for 5 years. Baseline angiographic characteristics and long-term clinical outcomes were compared between the two groups. Results. PCN group consisted of patients of younger age and represented more choroidal vascular hyperpermeability, polypoidal lesion, and history of central serous chorioretinopathy (CSC) at the time of diagnosis (all p  < 0.01). During the 5-year follow-up period, individuals in the PCN group received significantly fewer injections and reported better visual acuity compared to individuals in the type 1 nAMD group. A progressive decrease in the subfoveal choroidal thickness was observed in the type 1 nAMD group, while the thick choroid was maintained in the PCN group during the 5-year follow-up period. Conclusions. PCN developed in younger patients with a higher propensity of forming polypoidal lesions and a history of CSC. Long-term outcomes revealed that PCN had a thicker choroid and better visual prognosis with fewer number of intravitreal injection than that of type 1 nAMD.

Introduction. The objective of the study is to report 4-year treatment outcome with intravitreal Aflibercept injections for neovascular age-related macular degeneration (nAMD) as first life therapy in real-life. Patients and Methods. This is a prospective, monocenter, observational case series analysis. Data from treatment-naïve patients with nAMD with at least 4 years of follow-up were included in the analysis. Data including age, gender, and visual acuity measured on Early Treatment of Diabetic Retinopathy Study charts (ETDRS) and injection numbers were recorded. Spectral domain optical coherence tomography (SD-OCT) data at baseline, month 3, month 6, month 12, year 2, 3, and 4 were also recorded. Patients were treated with a modified treat and extend (T&E) regimen. Results. Of the 48 eyes with nAMD treated, only 31 eyes were available at the 4-year follow-up. The mean age was 81 ± 8 years. The VA gain was 7.3 ± 12.7 letters at 1 year 6.5 ± 12.5 letters at 2 years, VA gain 5.2 ± 17 letters at 3 years, and 6.2 ± 18.6 letters at 4 years. The reduction of central retinal thickness was 118 ± 187 μm at 4 years. Complete resolution of fluid was obtained in 18/31 eyes. The total number of injections was 5.7 ± 2.0 during the first year, 2.9 ± 2.9 during the second year, 3.5 ± 3.3 during the third year, and 4.0 ± 3.4 during the fourth year. The total number of injections was 16 ± 10.6, ranging from 3 to 52 injections. Ten eyes developed macular atrophy over the 4-year period. Conclusion. The results suggest that good long-term morphological and functional outcome can be achieved using Aflibercept in clinical setting.

ObjectiveTo compare the outcomes of trainee-led and specialist-led management of neovascular age-related macular degeneration.DesignProspective multicentre registry-based observational study.SettingOphthalmology training centres in Australia and Europe where both trainee-led and specialist-led models of care coexist.ParticipantsTreatment-naïve eyes with neovascular age-related macular degeneration and at least 12 months follow-up. 726 eyes were included in the study from two centres, 534 receiving trainee-led treatment and 192 specialist-led treatment.InterventionsThe management and outcomes of patients receiving trainee-led care were compared with those receiving specialist-led care.Main outcomes measuresThe primary outcome was the mean change in visual acuity at 12 months from first injection. Outcomes were also presented at 36 months where available.ResultsThe mean age of participants was 79 years and 65% were female. The adjusted change in acuity at 12 months in trainee-led vs specialist-led eyes was +3.2 letters vs +4.1 letters (difference −0.9 letters, 95% CI −3.4 to 1.5, p=0.473). The mean adjusted change in acuity at 36 months was −0.9 letters in trainees vs +0.2 letters for specialists (difference −1.1 letters, 95% CI −5.1 to 2.9, p=0.596). Eyes treated by trainees received fewer injections on average to 36 months (15.0 vs 19.0, p=0.004), although this trend was observed at one centre only.ConclusionsNo significant differences in outcome between eyes managed by trainees and eyes managed by specialists were observed. Appropriately structured trainee-led management of neovascular age-related macular degeneration is a reasonable approach where regulatory and practical considerations allow it.

Objective: To compare the anatomical and functional outcomes of intensive and relaxed intravitreal aflibercept regimen in the management of neovascular age-related macular degeneration. Methods: The medical records of 50 eyes of 50 patients with treatment-naive neovascular age-related macular degeneration, who underwent intravitreal aflibercept therapy in the Retinal Department of University of Health Sciences Okmeydanı Training and Research Hospital (Istanbul, Turkey), were retrospectively reviewed. The demographic features and best-corrected visual acuities at baseline and at 1st-, 2nd-, 3rd-, 4th-, 6th-, 10th- and 12th- months, optical coherence tomography measurements, presence of intraretinal fluid, subretinal fluid and intraocular pressure values were studied. The patients were divided into two groups: intensive (subretinal fluid intolerant) and relaxed (<200 microns subretinal fluid tolerated) intravitreal aflibercept regimens. Results: The change in the mean best-corrected visual acuities from baseline to 12th month was 13.72 ± 33.97 letters in the intensive treatment group and 8.68 ± 27.22 in the relaxed group. There was no statistically significant difference between the groups ( p = 0.566). Similar proportions of both groups achieved ⩾10 letters gain (%48 vs. %40, respectively; p = 0.755) and ⩾10 letters loss (%20 vs. %24, respectively; p = 0.755). The mean central subfield thickness values decreased statistically significantly in both groups ( p < 0.001). There was no statistically significant difference between the groups (442.40 ± 161.32 to 318.0 ± 63.10 vs. 431.64 ± 151.52 to 303.08 ± 140.91, respectively; p = 0.724). The mean total injection numbers were significantly lower in the relaxed group (6.4 ± 1.65 vs. 4.8 ± 1.45, respectively; p = 0.01). Conclusion: Relaxed intravitreal aflibercept regimen has comparable efficiency and safety outcomes at 12 months with intensive intravitreal aflibercept regimen with fewer injections in the management of neovascular age-related macular degeneration.

The current treatment of neovascular age-related macular degeneration (nAMD) generates an excessive care pressure in the public health system. The search for a satisfactory treatment regimen, whose anatomical and functional stability may be achieved, is a challenge and a goal to be reached. We analyzed the outcomes in a patient cohort under fixed regimen treatment with intravitreal aflibercept (IVA). A retrospective study, with at least 1-year follow-up, in consecutive treated unselected naïve patients was carried out. Standard protocol was performed and evaluated at baseline, month 4 (after loading dose, LD), and month 12 (after fixed bimonthly regimen). One hundred six patients (123 eyes) aged 80.3 ± 7.7 years were included, receiving 6.8 ± 0.7 IVA. Visual acuity gain after LD was 5.5 ± 12.0 letters ( p < 0.0001 ). At month 12, 23 eyes (18.7%) gained ≥15 letters and 58 (47.1%) had best-corrected visual acuity ≥20/40 (70 letters). The improvement in visual acuity was lower in patients with polypoidal choroidal vasculopathy (+4.9 ± 18.1 letters; p = 0.2544) and somewhat higher in patients with retinal angiomatous proliferation (+5.4 ± 12.3 letters; p = 0.0373 ). Dry macula was present in only 9.8% of cohort at baseline vs. 69.7% at month 12 ( p < 0.0001 ). Atrophy was the most observed complication and related to the elderly patients. The average of follow-up visits was 3 ± 0.5. Functional and anatomical improvement were observed with IVA in a fixed bimonthly regimen treatment after LD, with results maintained up to one year with a good compliance. The fixed bimonthly regimen optimized patient management and logistic issues.

Purpose: This article describes eyes that achieved extended remission of neovascular age-related macular degeneration (NVAMD) following acute endophthalmitis. Methods: Adults who presented to the Duke Eye Center with acute endophthalmitis over a 9-year period and had at least 3 months of follow-up were identified. A retrospective review of medical records was performed to collect clinical data including demographic information, examination findings, etiology, treatment, and outcomes. Results: A total of 133 eyes of 130 patients with endophthalmitis were identified. Of these, 15 eyes of 14 patients (11.3%) were receiving intravitreal antivascular endothelial growth factor (anti-VEGF) injections for NVAMD. Six of these 15 eyes (40%) did not require an anti-VEGF injection after endophthalmitis for a mean of 36.2 months. Endophthalmitis was injection-related in 5 of 6 eyes (83%) and Baerveldt glaucoma drainage device–related in 1 of 6 eyes (17%). Two of the 6 (33%) had culture-proven infectious endophthalmitis, whereas 4 of 6 (67%) had culture-negative endophthalmitis. Five of 6 eyes have required no anti-VEGF therapy to date; the remaining eye restarted intravitreal aflibercept therapy 9.3 months after endophthalmitis. Conclusions: Acute endophthalmitis may be associated with reduced activity of choroidal neovascularization in a subset of eyes with NVAMD.

The aim of the present study was to determine the efficacy and safety of intravitreal brolucizumab therapy for neovascular age-related macular degeneration (AMD) in the real-world setting. The REBA study (real-world experience with brolucizumab in wet AMD) was a retrospective, observational, multicentric study that included 78 consecutive patients (105 eyes), with neovascular AMD, who received brolucizumab therapy. Both treatment-naive and switch-therapy patients were included. Switch therapy was based either on fluid recurrence, fluid recalcitrance, or inability to extend beyond q4/q6. All relevant data were collected. The primary outcome measure was change in best-corrected visual acuity (BCVA) over time. Secondary outcome measures included determination of change in central subfield thickness (CST) and complications. The mean baseline BCVA was 49.4 ± 5.4 letters and 40 ± 3.2 letters, and corresponding mean BCVA gain was +11.9 ± 3.9 letters (p = 0.011) and +10.4 ± 4.8 letters (p = 0.014) in the treatment-naive and switch-therapy groups, respectively. The change in CST was significantly decreased in the treatment-naive (p = 0.021) and the switch-therapy (p = 0.013) groups. The mean follow-up was 10.4 months in both groups. One patient in the switch-therapy group developed vascular occlusion and another a macular hole after the fifth brolucizumab injection. Both patients recovered uneventfully. In conclusion, patients showed a very good anatomical and functional response to brolucizumab therapy in the real world, regardless of prior treatment status, until the end of the follow-up period. Two significant untoward events were noted.
