Importance: To provide new insights into aflibercept effect in non-naive-treated patients with neovascular age-related macular degeneration. Purpose: To assess the efficacy of intravitreal aflibercept in patients with neovascular age-related macular degeneration without optimal response to previous anti-vascular endothelial growth factor A therapy. Design: Single-arm, multi-centre, prospective study. Participants: Patients ⩾50 years with active neovascular age-related macular degeneration, best-corrected visual acuity between 20/32 and 20/320 with suboptimal response to ranibizumab or bevacizumab. Methods: Aflibercept was administered monthly (3-first months), and bimonthly thereafter until month 8. Anatomical and functional outcomes were assessed. Main outcome measure: Percentage of eyes without intra or subretinal fluid on optical coherence tomography after 3-monthly loading doses of aflibercept. Results: A total of 46 patients were included. At week 12, 45.7% (95% confidence interval: 31.5%–60.1%) of eyes showed no fluid on optical coherence tomography. The mean (standard deviation) best-corrected visual acuity increased from 65.1 (8.3) to 69.6 (8.1) letters (+4.5 (5.8) p < 0.0001) and was stabilized at week 40 as compared to baseline. Mean central macular thickness decreased from 430 (119) µm to 323 (100) µm at week 12 (–107 (90) µm, p < 0.0001) and was reduced at week 40 (–46 (111) µm, p = 0.0056). At week 40, 21.7% (95% confidence interval: 9.8%–33.7%) had no fluid. There was a case of presumed noninfectious endophthalmitis that was successfully managed. Conclusion: Almost half of patients presented no fluid on optical coherence tomography at week 12, and there was a clinically significant improvement in best-corrected visual acuity. At week 40, one in five patients did not show intra or subretinal fluid, central macular thickness decreased and best-corrected visual acuity was stabilized compared to baseline.

Purpose: To assess intra- and subretinal fluid during the loading phase with intravitreal ranibizumab in exudative age-related macular degeneration and to quantify the accuracy of crosshair scan spectral-domain optical coherence tomography with regard to retinal fluid. Methods: This is a retrospective study of 31 treatment-naive patients who received 3 monthly intravitreal ranibizumab injections. Visual acuity and the presence of retinal fluid were assessed at each visit using volume and crosshair scan protocols. Results: Visual acuity improved and central retinal thickness decreased significantly during the loading phase. However, retinal fluid persisted in two thirds of the patients. The accuracy of the crosshair scan to detect fluid was 93%. Conclusions: A substantial proportion of eyes had persistent fluid after 3 months of ranibizumab injections. However, visual improvement was independent of residual fluid. Message: Crosshair scans detect relevant collections of retinal fluid accurately and may be sufficient in daily clinical practice.

Ranibizumab Treatment

Abstract Background: To evaluate the efficacy and safety of two individualized ranibizumab retreatment schemes in neovascular age-related macular degeneration. Methods: Patients (N=671) were randomized (1:1) to receive three initial monthly ranibizumab 0.5 mg injections, then retreatment guided by either best-corrected visual acuity (BCVA) loss (Group I) or BCVA loss and/or signs of disease activity on optical coherence tomography (OCT; Group II). The study was terminated prematurely and the decision to discontinue the study was made by the sponsor. Efficacy analyses were performed on patients who completed 12 months of the originally planned 24-month study. Safety analyses are presented for all safety analyzable patients. Results: Of 671 randomized patients, 305 completed 12 months of the study. For the 12-month completers, baseline mean (standard deviation) BCVA and reading-center evaluated central subfield thickness (CSFT) were comparable [Group I: 60.9 (13.10) letters and 517.7(201.79) µm; Group II: 60.2 (12.21) letters and 515.3 (198.37) µm]. The change from baseline at Month 12 in BCVA was 6.7 (13.48) letters in Group I and 8.3 (13.53) letters in Group II and the change in CSFT was −161.3 (163.48) µm and −175.3 (170.45) µm, respectively. The mean number of ranibizumab injections was 8.2 in Group I and 8.4 in Group II. Conclusion: Ranibizumab treatment resulted in visual and anatomic gains at 12 months for both retreatment strategies, with a trend in favor of OCT-guided vs BCVA loss guided retreatment. No new safety signals were seen. Trial registration: www.ClinicalTrials.gov (NCT01780935).

Introduction: Anti-vascular endothelial growth factor therapy has revolutionized the treatment of wet age-related macular degeneration; however, it is important to monitor actual use of ranibizumab and related treatment outcomes in routine practice.Material and Methods: This was a retrospective, observational study to monitor the 2-year outcomes following ranibizumab treatment for wet age-related macular degeneration in Portugal. Patients treated between January 2009 and December 2009 were retrospectively evaluated. All decisions were made by the treating physician in accordance with their usual routine clinical practice. The primary assessment was mean change in visual acuity score using Early Treatment Diabetic Retinopathy Study or Snellen equivalent.Results: A total of 128 patients with wet age-related macular degeneration were analyzed (mean age 79.4 years; mean visual acuity score 54.2 letters). Mean change in visual acuity score from baseline was –1.6 letters (n = 82) at year one and –5.1 letters (n = 72) at year two. The mean number of ranibizumab injections was 3.8 (year one) and 1.6 (year two). On average, patients attended 8.6 and 5.0 visits and optical coherence tomography was used in 75.0% of patients in year one and in 56.3% of patients in year two, respectively.Discussion: Despite a relatively high number of visits, including monitoring visits and use of optical coherence tomography - guided therapy, few injections were administered and visual acuity was not improved.Conclusion: These findings indicate that as-needed treatment resulted in under-dosing in a real-life setting in Portugal. Such limitations may also be related to increasing numbers of patients, resulting in clinic saturation.

Abstract Background/objectives To investigate the association between optical coherence tomography (OCT) markers of lesion activity and changes in visual acuity (VA) during anti-vascular endothelial growth factor (anti-VEGF) therapy of eyes diagnosed with neovascular age-related macular degeneration (nAMD); and how VA and OCT markers are considered in physicians’ decision to retreat with anti-VEGFs. Subjects/methods Retrospective, non-comparative, non-randomised cohort study involving electronic medical record data collected from 1190 patient eyes with nAMD diagnosis at two sites in the United Kingdom. Two sub-cohorts consisting of 321 and 301 eyes, respectively, were selected for analyses. Results In 321 eyes, absence of IRF or SRF at ≥2 clinic visits resulted in a gain of five ETDRS letters from baseline, compared with two letters gained in eyes with <2 clinic visits with absence of IRF (p = 0.006) or SRF (p = 0.042). Anti-VEGF treatment was administered at 421 clinic visits, and 308 visits were without treatment. Comparing treatment visits with non-treatment visits, the maximum difference in frequency of OCT markers of lesion activity were for intraretinal fluid (IRF; 24% versus 5%) and subretinal fluid (SRF; 32% versus 5%). Pigment epithelial detachment (PED) was reported in 58% of treatment visits compared with 36% in non-treatment visits. VA loss was not a consistent trigger for retreatment as it was present in 63% of injection visits and in 49% of non-injection visits. Conclusions Retreatment decision making is most strongly influenced by the presence of IRF and SRF and less by the presence of PED or VA loss.

Purpose To report the bacillary layer detachment on optical coherence tomography in exudative age-related macular degeneration. Methods Retrospective, observational cases Case descriptions Two cases of exudative age-related macular degeneration, one diagnosed as polypoidal choroidal vasculopathy following exudative age-related macular degeneration and other as wet age-related macular degeneration with choroidal neovascular membrane showed separation of myoid and ellipsoid zones of photoreceptor layer on optical coherence tomography. This is termed as BALAD. Other associated features noted were the presence of subretinal hyperreflective material, submacular hemorrhage and subretinal fluid. Both cases were treated with monthly intravitreal injections of Inj. Ranibizumab (0.5 mg/0.05 ml). Following 3 intravitreal injections at monthly intervals, reattachment of the bacillary layer detachment were noted in case 1 while the bacillary layer detachment persisted in case 2. Conclusion Multimodal imaging using optical coherence tomography in these cases revealed the separation of the bacillary layer following exudative age-related macular degeneration; a finding which is not routinely described in literature.

Purpose Visual outcome in patients with neovascular age-related macular degeneration is variable. We aimed to evaluate for association between socioeconomic status visual acuity in neovascular age-related macular degeneration. Methods A retrospective single-center study of a consecutive group of neovascular age-related macular degeneration patients was performed. Socioeconomic status was determined for each patient based on the 2008 Israeli census. Medical information was extracted from medical records and included visual acuity and optical coherence tomography parameters. Associations between socioeconomic status and clinical outcomes were analyzed. Results A total of 233 patients were included in the analysis. A correlation was found between low baseline visual acuity of the first eye diagnosed with neovascular age-related macular degeneration and low socioeconomic status (r = −0.13, p = 0.049; n = 233). The difference between the visual acuity of the lowest and the highest socioeconomic status categories at baseline was approximately 3 ETDRS lines (p = 0.048). Socioeconomic status and baseline visual acuity of the second eye of the same individual with neovascular age-related macular degeneration were not correlated (r = −0.05, p = 0.95). Socioeconomic status was not associated with the number of anti-vascular endothelial growth factor injections of the first or second eye, or the visual acuity outcome of the first or second eye after 1 year of therapy (p = 0.421, p = 0.9, respectively). Central subfield thickness of the first eye at presentation as measured by spectral-domain optical coherence tomography was associated with socioeconomic status (r = −0.31 p = 0.001). Conclusion Individuals of lower socioeconomic status presented at more advanced stage of the disease when developing neovascular age-related macular degeneration in the first eye but not in the second eye. The research underscores the importance of improving referral patterns and awareness for the lowest socioeconomic status classes.

Purpose: To examine the effect of a long-term nutritional supplementation on age-related macular degeneration progression. Methods: In this prospective, double-blind, placebo-controlled study, 80 patients with intermediate age-related macular degeneration were randomized (2:1) to receive 1 tablet/day of a nutritional supplement containing a mixture of carotenoids, vitamins and omega-3 fatty acids or placebo. Age-related macular degeneration progression assessed by digital fundus photography (primary outcome) and best-corrected visual acuity were evaluated. Differences between arms were tested using chi-square test or Fisher’s exact test. Results: Seventy-four patients completed the follow-up at 24 months (48 in the treated arm and 26 in the placebo arm). An age-related macular degeneration progression was observed in the 2.1% of patients of the treated arm and in the 15.4% of patients in the placebo arm (p = 0.05, Fisher’s exact test). Best-corrected visual acuity data alone were not statistically significant among groups. Conclusion: A clinically meaningful stabilization of intermediate age-related macular degeneration over a period of 2 years may be obtained by treating patients with a mixture of carotenoids, vitamins and omega-3 fatty acids.
