AimsTo investigate changes in ocular perfusion following three consecutive intravitreal injections with aflibercept for treatment of neovascular age-related macular degeneration (nAMD).MethodsThe study included 20 eyes from 20 Caucasian patients with unilateral nAMD and 20 fellow eyes. All nAMD eyes were treated with standard intravitreal injection of aflibercept (IVA; 2 mg). Measurements of ocular perfusion at the optic nerve head (ONH) and the choroid were performed with laser speckle flowgraphy (LSFG). Measurements were conducted at baseline, 1 week after the first injection, at the time point of the second and third injection as well as 1 month after the third injection.ResultsIn treated eyes, mean blur rate (the main output parameter of LSFG) in the ONH microvasculature and in the choroid was significantly reduced 1 week after the first IVA treatment. The effect persisted throughout the entire follow-up period (p<0.001). No change in ocular perfusion was observed in fellow eyes.ConclusionsIVA for treatment of nAMD leads to a reduction in perfusion of the ONH and the choroid in the treated eye with no apparent effect on the fellow eye.

Purpose. To report long-term visual and anatomical outcomes in eyes with neovascular age-related macular degeneration (nAMD) treated with a treat-and-extend regimen (TER) of intravitreal antivascular endothelial growth factor (anti-VEGF) injections in real-world settings. Methods. Retrospective cohort study of consecutive patients with nAMD treated with a TER of anti-VEGF intravitreal injections by a single retina specialist (GC). Patients with nAMD who had at least one year of follow-up were identified using an electronic database. Best-corrected visual acuity (BCVA), comprehensive ophthalmologic examination, and macular OCT were performed at each visit. Patients received a loading dose of three monthly intravitreal injections and then were treated according to a TER of bevacizumab, ranibizumab, and/or aflibercept. The number of injections, BCVA, and central retinal thickness (CRT) were evaluated during the follow-up period. Results. 180 eyes from 180 patients were included in the study. Mean age was 75 ± 9 (range: 51–96). Mean BCVA was 0.77 ± 0.64 LogMAR at baseline, 0.69 ± 0.58 LogMAR (p=0.0057) after loading phase, 0.64 ± 0.55 LogMAR (p=0.0001) after 6 months of TER, and 0.76 ± 0.71 LogMAR after 6 years of treatment (n = 32 at year 6). CRT decreased significantly after the loading phase (p=0.0002). The mean number of intravitreal injections per year was 7.6 during the first three years of treatment and then decreased to 5.9 during year 4 to 7. Conclusions. This retrospective study of 180 nAMD patients treated with a TER of intravitreal anti-VEGF demonstrates an initial improvement of BCVA after loading phase, followed by long-term visual stabilization for at least six years. These results were obtained with a high number of injections, averaging close to six injections per year during long-term follow-up. In light of the natural evolution of nAMD, these data support the long-term efficacy of this treatment under real-world conditions of heterogeneity of patients and type of anti-VEGF used.

Purpose. To assess real-life anatomical and functional outcomes of switch to bevacizumab in patients undergoing aflibercept intravitreal injections for nAMD. Methods. Retrospective chart review of all patients diagnosed with nAMD and undergoing intravitreal injections of aflibercept who switched to bevacizumab after the resolution XI/1986 of Lombardy Region. Results. Among 128 patients undergoing intravitreal injections, a total of 29 eyes of 29 patients met all inclusion criteria and were included in the statistical analysis. Best corrected visual acuity and central macular thickness did not change significantly ( p > 0.05 ) between baseline, after the loading phase, and at the last follow-up. Conclusion. Switching to bevacizumab has been safe and efficacious in patients responding to the loading phase. According to our results, the restrictions imposed by Lombardy Region did not cause any harm to patients undergoing intravitreal anti-VEGF injections.

Purpose To evaluate the association between subfoveal choroidal thickness and the visual outcome in eyes with type 1 choroidal neovascularization (CNV) due to neovascular age-related macular degeneration (nAMD). Methods This was a retrospective, longitudinal, cross-sectional study including patients diagnosed with nAMD type 1 lesions managed with intravitreal injections of ranibizumab in a PRN strategy during 24 months. Retrospective chart review of patients with type 1 CNV recording the visual acuity, number of intravitreal injections, multimodal imaging data, and follow-up period was performed. Subfoveal choroidal thickness was measured using enhanced depth imaging scans obtained with spectral-domain optical coherence tomography. Results Twenty-five eyes of 21 patients were included. The mean baseline logMAR best-corrected visual acuity was 0.52 (+0.35) (median 0.5; range 0.1-1; interquartile range (IQR) 0.3-0.8) and improved to 0.39 (+0.39) (median 0.4; range 0.1-1; IQR 0.2-0.5) by the end of the follow-up (p = 0.038). Subfoveal choroidal thickness was 202.8 (+60.3) μm (median 218; range 81-285; IQR 146-258). Statistical mixed effects model demonstrated an association between rate of improvement of visual acuity with subfoveal choroidal thickness after 24 months (p<0.001) (95% confidence interval 0.0002-0.0001 logMAR month μm); higher thickness values were correlated with better visual acuity. Conclusions Thicker subfoveal choroid was associated with better visual outcomes in patients with type 1 CNV due to nAMD following a strict PRN regimen with intravitreal ranibizumab at 24 months of follow-up.

SummaryA 50-year-old female was diagnosed with significant peripapillary choroidal neovascularization (PCNV) in the left eye (LE). 12 months after a close follow-up, 4 intravitreal injections with bevacizumab and retinal laser photocoagulation were performed to limit the distribution of the lesion. A year after the primary diagnosis in the LE, a tiny PCNV also developed in the right eye (RE). Simultaneous activity was additionally observed in both peripapillary lesions at the time. At the last follow-up, after 43 months, the best corrected visual acuity in the RE was 0.8, but in the LE it was only 0.2. In total, the LE received 6 intravitreal injections with bevacizumab, while the RE received 3 injections.The case report concludes that early diagnosis and intervention helps maintain visual acuity better in the cases of a small lesion than in developed significant PCNV with intense activity characterised with oedema, hard exudates and haemorrhages.

We report on a case of an unusual activation of one of 2 quiescent, nonexudative choroidal neovascular membranes in a patient treated with anti-VEGF injections for exudative age-related macular degeneration in his fellow eye. After almost 2 years of close observation, one of these membranes became exudative, and anti-VEGF therapy was started. This case illustrates the unpredictability of subclinical neovascularization and confirms the utility of optical coherence tomography angiography in the diagnosis and follow-up of these changes. Patients with an exudative age-related degeneration in one eye should have their fellow eyes monitored meticulously.

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.
