Purpose. To study the short-term anatomical and functional outcomes in patients with neovascular age-related macular degeneration (nAMD) who were previously treated with conbercept and switched to ranibizumab or bevacizumab due to persistent activity. Methods. This retrospective single-arm study included nAMD patients who were followed up for at least three months after switching from at least 3 monthly intravitreal conbercept injections to bevacizumab or ranibizumab for persistent choroidal neovascularization (CNV) activity. The demographic data, treatments, best-corrected visual acuity (BCVA), central macular thickness (CMT), and the height of pigmented epithelial detachment (PED) before and after switching were recorded and analyzed. Results. A total of 64 eyes of 64 patients were included with a mean follow-up of 9.6 ± 3.0 months. The average number of injections of conbercept was 3.6 ± 0.8 (range, 3–5) before switching. 18 eyes were switched to bevacizumab, and the other 46 eyes were switched to ranibizumab. After switching, mean BCVA slowly improved from 0.73 ± 0.48 to 0.64 ± 0.41 (p=0.0132) at one month after the last intravitreal injection of ranibizumab or bevacizumab during the mean follow-up of 4.4 ± 2.0 months. One month after switching, the mean CMT decreased significantly from 294.9 ± 121.8 μm to 230.9 ± 107.0 μm (p<0.0001) and kept stable during the follow-up. There was a significant reduction of maximum PED height (mPEDH) at the first month after switching (from 384.3 ± 340.3 μm to 287.2 ± 245.2 μm, p=0.0018) and kept stable during the follow-up. The mean PED height at foveal center (cPEDH) showed a regression over time after switching (from 169.3 ± 230.6 μm to 130.5 ± 180.2 μm, p=0.0227) and also kept stable during the follow-up. The proportion of patients with IRF was slightly increased but not statistically significant before switching. After switching, this proportion decreased significantly from 96.9% to 81.3% at one month after the first intravitreal injection of ranibizumab or bevacizumab (p=0.0086). The proportion of patients with SRF did not change significantly before and after switching. The mean decrease of mPEDH and cPEDH at the last follow-up after switching was significantly larger in the IVR subgroup than in the IVB subgroup (p=0.023 and 0.010). Conclusion. Our results indicate that switching from intravitreal conbercept injections to bevacizumab or ranibizumab can lead to significant improvement of CMT, PED, and IRF and slight improvement of BCVA in a short period of time for persistent nAMD patients.

Background: The purpose of this study was to describe early changes in the morphology of pigment epithelium detachments (PED) after an intravitreal injection of Brolucizumab into eyes with macular neovascularization secondary to exudative age-related macular degeneration (e-AMD). Method: We included twelve eyes of 12 patients with PED secondary to e-AMD which were not responding to prior anti-VEGF treatments. An ophthalmic examination and an assessment of PED-horizontal maximal diameter (PED-HMD), PED-maximum high (PED-MH) and macular neovascularization (MNV) flow area (MNV-FA) by the means of structural optical coherence tomography (OCT) and OCT Angiography (OCT-A) were performed at baseline, as well as 1, 7, 14 and 30 days after the injection. Results: The mean age of the population of study was 78.4 (SD ± 4.8). The mean number of previous Ranibizumab or Aflibercept injections was 13 (SD ± 8). At the last follow-up visit, the PED-HMD did not significantly change (p = 0.16; F(DF:1.94, 20,85) = 1.9), the PED-MH showed a significant reduction [p = 0.01; F(DF:1.31, 14.13) = 6.84.] and the MNV-FA did not significantly differ (p = 0.1; F(1.97, 21.67) = 2.54) from baseline. No signs of ocular inflammation were observed during follow-up. Conclusions: A single Brolucizumab injection was able to determine the short-term effects on PEDs’ anatomical features of eyes with an unresponsive e-AMD.

Abstract Background Thousands of phacoemulsification surgeries are performed on eyes with age-related macular degeneration (AMD) complicated by choroidal neovascular membrane (CNV) in the United Kingdom each year. As populations age this number is expected to rise. Controversy over phacoemulsification’s influence on CNV activity limits the information which clinicians and these patients use to decide on surgery. This observational study aims to resolve this controversy by reporting on intravitreal injection (IVI) frequency as a pragmatic marker of CNV activity in a large cohort. Methods A cohort of eyes with AMD complicated by CNV (n = 327) that underwent cataract surgery at a single tertiary centre from 2014 to 2019 were identified. These cases were matched by interval since CNV diagnosis at a specified ‘time zero’ within the follow-up of pseudophakic eyes with AMD (n = 327). Data concerning demographics, visual acuity (VA) and intravitreal injection frequency before and after ‘time zero’/phacoemulsification were collected. Results Following ‘time zero’/phacoemulsification’ the mean reduction in annual IVI frequency was 0.6 injections/year (95% CI 0.4,0.9) and 0.4 injections/year (95% CI 0.1,0.7) in the comparison and phacoemulsification cohorts respectively. The mean VA gain 12 months after phacoemulsification in the intervention cohort was 11.3 (95% CI 9.2,13.4) early treatment of diabetic retinopathy study (ETDRS) letters, with 214 eyes (65.4%) having gained ≥5 ETDRS letters after surgery. Conclusions Phacoemulsification has no clinically significant impact on the activity of pre-existent CNV secondary to AMD. Phacoemulsification should be offered to patients with AMD and cataract that limits vision, regardless of CNV activity.

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.

AbstractThere is a lack of treatment aimed at the regression of reticular pseudodrusen (RPD) secondary to age-related macular degeneration (AMD). The aim of this prospective, pilot study is to evaluate the safety and short-term efficacy of subthreshold laser treatment (SLT) in patients affected by RPD secondary to dry AMD (dAMD). Twenty eyes of 20 patients (mean age 78.4 ± 6.8 years) with RPD secondary to dAMD were prospectively enrolled. All patients were treated in an extrafoveal area of 1.27 mm2 using end-point management yellow subthreshold laser and followed for 3 months. Best-corrected visual acuity was 0.140 ± 0.09 LogMAR at the baseline and no changes were observed during the follow-up (p = 0.232). No significant worsening was disclosed before and after the treatment analyzing the macular sensitivity of the treated area (p = 0.152). No topical and/or systemic side effects were disclosed during the 3-month follow-up. The distribution among the RPD stages changed after the treatment (p < 0.001). In detail, in the treated area, we observed a significant increase in the number of Stage 1 RPD during the follow-up (p = 0.002), associated with a significant decrease of Stage 3 RPD (p = 0.020). Outer nuclear layer (ONL) thickness analysis showed a significant increase after the treatment associated with RPD regression (p = 0.001). End-point management SLT appears a safe treatment for RPD secondary to dAMD, showing short-term safety outcomes. Our results suggest that SLT could be effective in inducing a RPD regression in terms of RPD stage and ONL thickening.

Purpose: To compare the response to ranibizumab between patients with typical neovascular age-related macular degeneration (tAMD) and those with polypoidal choroidal vasculopathy (PCV), and to determine the predictors for the outcomes. Methods: Fifty-nine eyes from 59 consecutive patients (tAMD: 27 eyes, PCV: 32 eyes) were treated with three monthly ranibizumab injections followed by as-needed retreatment. Best-corrected visual acuity (BCVA) and morphological parameters were evaluated over 24 months of follow-up. Results: The mean BCVA in tAMD and PCV patients was significantly improved at 3 months (-0.22 and -0.09 logMAR units, respectively). The improvement in BCVA was sustained up to 24 months in tAMD (p = 0.01) but not in PCV patients. The significant predictor for good response to ranibizumab in tAMD patients was the improvement of BCVA at 3 months, whereas that in PCV patients was the anatomical resolution at 3 months. Conclusions: Ranibizumab is an effective therapy for tAMD and PCV over 24 months. The predictors for good outcome might be different between tAMD and PCV.

Purpose: To investigate the limited response to aflibercept after switching to aflibercept in neovascular age-related macular degeneration (AMD). Methods: This retrospective study included 70 eyes with neovascular AMD that were initially treated with ranibizumab and then switched to aflibercept. The incidence and timing of the limited response to aflibercept were identified and visual outcome was compared between eyes with and without limited response. In addition, factors predictive of limited response were analyzed. Results: A limited response to aflibercept was noted in approximately 1/5 of the patients who underwent switching to aflibercept in neovascular AMD. Switching to aflibercept was performed at a mean of 16.2 ± 12.7 months after diagnosis. During the mean 34.7 months of follow-up after switching, limited response was noted in 15 eyes (21.4%) at a mean of 22.0 ± 13.9 months after switching. The degree of reduction in visual acuity was mean logMAR 0.34 ± 0.41 in eyes with limited response and mean 0.06 ± 0.20 in eyes without (p = 0.002). In addition, the duration between the diagnosis and the switching was shorter (p = 0.012), and the number of ranibizumab injections before switching was lower (p = 0.016) in eyes with limited response than in eyes without. Conclusions: Patients who showed limited response to aflibercept after switching to aflibercept showed a worse visual outcome. The probability of having a limited response is higher when the switching is performed earlier.

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.

Intravitreal ranibizumab therapy is widely used in treatment of subfoveal choroidal neovascularisation (CNV) in age-related macular degeneration. We wanted to study the effect of intravitreal ranibizumab therapy in peripapillary CNV. A prospective recording of treatment outcomes in twelve eyes (12 patients) with peripapillary CNV with intravitreal injections of ranibizumab was performed. The patients received a series of 3 injections 4–6 weeks apart, and then a new ophthalmic examination was made including OCT and further therapy was given if the peripapillary CNV was still active. Nine patients had idiopathic peripapillary CNV, and in 3 patients it was associated to age-related macular degeneration. Followup had to be at least 6 months. The mean follow-up time was 15.9 (range 9–27) months and the mean number of injections 6.2 (3–10). In 10 patients treatment had resulted in an inactivation of the peripapillary CNV, but 3 of them had reactivation, while 2 patients had no inactivation. Currently, 5 patients are continuous to receive treatment. VA improved in 10 patients. Intravitreal ranibizumab therapy appears to be effective in patients with peripapillary CNV, but in some cases there is repeated reactivation or continuous activity of the peripapillary CNV.
