Purpose: This article assesses anatomical and visual outcomes after intravitreal antivascular endothelial growth factor (anti-VEGF) treatment in fellow eyes with wet age-related macular degeneration (AMD). Methods: A retrospective chart review was conducted of 349 patients diagnosed with wet AMD between 2005 and 2017 at a single academic institution. Initial diagnosis of unilateral wet AMD and a minimum follow-up time of 1 year after diagnosis were required for inclusion. Individuals were excluded if the initial diagnosis of wet AMD was made at an outside institution, if they had received prior treatment at another institution, or if they had bilateral wet AMD at the time of inclusion. Best-corrected visual acuity, optical coherence tomography (OCT) parameters, and frequency and type of intravitreal anti-VEGF injections were recorded. MedCalc Statistical Software version 17.6 (MedCalc Software) and GraphPad Software (GraphPad Software, Inc) were used for statistical analysis. Results: Of the 349 patients with wet AMD, 192 were included in the study (55%). Of these, 47 (24.5%) developed wet AMD in the fellow eye. The average time to second-eye conversion was 2.6 years, with fellow-eye conversion more likely to occur after 2 years of unilateral disease. On average, patients received 2.16 fewer injections per year in the fellow eye compared with the initially diagnosed eye ( P = .03), and fellow eyes tended to have better OCT results after 12 months of treatment. In addition, compared with ranibizumab and bevacizumab, aflibercept injections appeared to improve visual acuity both in initially diagnosed and fellow eyes. Conclusions: Exudative AMD in the fellow eye has a decreased treatment burden and better visual outcomes compared with the initial eye, which may be attributed to more frequent surveillance and early diagnosis.

Purpose: The aim was to describe baseline characteristics of the fellow eye of patients with neovascular age-related macular degeneration (nAMD). Methods: A pooled, post hoc analysis of patients with nAMD enrolled in the VIEW studies was carried out. The VIEW studies compared intravitreal aflibercept (monthly or every 2 months after 3 monthly injections) with monthly ranibizumab. Baseline choroidal neovascularization (CNV) status of fellow eyes and baseline best-corrected visual acuity (BCVA) and lens status of all eyes were evaluated. Additional analyses evaluated the presence of drusen and pigment in fellow eyes. Results: When comparing both eyes, baseline BCVA was worse in 23.8% of fellow eyes and in 75.2% of study eyes. Lens status of fellow eyes and study eyes was similar. Baseline visual acuity of the study eye and that of the fellow eye were not correlated. Most fellow eyes had signs of early AMD, with 34.6% (n = 843) of fellow eyes having evidence of scarring. Conclusions: In patients in the VIEW studies, most fellow eyes had evidence of AMD, highlighting the importance of examining both eyes, with close follow-up thereafter, in order to detect and treat CNV earlier as needed.

AbstractAge-related macular degeneration (AMD) is a devastating retinal disease that results in irreversible vision loss in the aged population. The complex genetic nature and degree of genetic penetrance require a redefinition of the current therapeutic strategy for AMD. We aimed to investigate the role of modifiers for current anti-VEGF therapy especially for non-responder AMD patients. We recruited 78 wet AMD cases (out of 278 AMD patients) with their socio-demographic and treatment regimen. Serum protein levels were estimated by ELISA in AMD patients. Data pertaining to the number of anti-VEGF injections given (in 1 year) along with clinical images (FFA and OCT) of AMD patients were also included. Visual acuity data (logMAR) for 46 wet AMD cases out of a total of 78 patients were also retrieved to examine the response of anti-VEGF injections in wet AMD cases. Lipid metabolizing genes (LIPC and APOE) have been identified as chief biomarkers for anti-VEGF response in AMD patients. Both genotypes ‘CC’ and ‘GC’ of LIPC have found to be associated with a number of anti-VEGF injections in AMD patients which could influence the expression of B3GALTL,HTRA1, IER3, LIPC and SLC16A8 proteins in patients bearing both genotypes as compared to reference genotype. Elevated levels of APOE were also observed in group 2 wet AMD patients as compared to group 1 suggesting the significance of APOE levels in anti-VEGF response. The genotype of B3GALTL has also been shown to have a significant association with the number of anti-VEGF injections. Moreover, visual acuity of group 1 (≤ 4 anti-VEGF injections/year) AMD patients was found significantly improved after 3 doses of anti-VEGF injections and maintained longitudinally as compared to groups 2 and 3. Lipid metabolising genes may impact the outcome of anti-VEGF AMD treatment.

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.

ObjectiveAge-related macular degeneration (ARMD) is a leading cause of visual impairment. Intravitreal injections of anti-vascular endothelial growth factor (VEGF) are the standard treatment for wet ARMD. There is however, variability in patient responses, suggesting patient-specific factors influencing drug efficacy. We tested whether single nucleotide polymorphisms (SNPs) in genes encoding VEGF pathway members contribute to therapy response.Methods and analysisA retrospective cohort of 281 European wet ARMD patients treated with anti-VEGF was genotyped for 138 tagging SNPs in the VEGF pathway. Per patient, we collected best corrected visual acuity at baseline, after three loading injections and at 12 months. We also registered the injection number and changes in retinal morphology after three loading injections (central foveal thickness (CFT), intraretinal cysts and serous neuroepithelium detachment). Changes in CFT after 3 months were our primary outcome measure. Association of SNPs to response was assessed by binomial logistic regression. Replication was attempted by associating visual acuity changes to genotypes in an independent Japanese cohort.ResultsAssociation with treatment response was detected for seven SNPs, including in FLT4 (rs55667289: OR=0.746, 95% CI 0.63 to 0.88, p=0.0005) and KDR (rs7691507: OR=1.056, 95% CI 1.02 to 1.10, p=0.005; and rs2305945: OR=0.963, 95% CI 0.93 to 1.00, p=0.0472). Only association with rs55667289 in FLT4 survived multiple testing correction. This SNP was unavailable for testing in the replication cohort. Of six SNPs tested for replication, one was significant although not after multiple testing correction.ConclusionIdentifying genetic variants that define treatment response can help to develop individualised therapeutic approaches for wet ARMD patients and may point towards new targets in non-responders.

BackgroundTo describe 10-year trends in visual outcomes, anatomical outcomes and treatment burden of patients receiving antivascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (nAMD).MethodsRetrospective cohort study of treatment-naïve, first-affected eyes with nAMD started on ranibizumab before January 1, 2009. The primary outcome was time to best-corrected visual acuity (BCVA) falling ≤35 ETDRS letters after initiating anti-VEGF therapy. Secondary outcomes included time to BCVA reaching ≥70 letters, proportion of eyes with BCVA ≥70 and ≤35 letters in 10 years, mean trend of BCVA and central retinal thickness over 10 years, and mean number of injections.ResultsFor our cohort of 103 patients, Kaplan-Meier analyses demonstrated median time to BCVA reaching ≤35 and ≥70 letters were 37.8 (95% CI 22.2 to 65.1) and 8.3 (95% CI 4.8 to 20.9) months after commencing anti-VEGF therapy, respectively. At the final follow-up, BCVA was ≤35 letters and ≥70 letters in 41.1% and 21%, respectively, in first-affected eyes, while this was the case for 5.4% and 48.2%, respectively, in a patient’s better-seeing eye. Mean injection number was 37.0±24.2 per eye and 53.6±30.1 at patient level (63.1% of patients required injections in both eyes).ConclusionsThe chronicity of nAMD disease and its management highlights the importance of long-term visual prognosis. Our analyses suggest that one in five patients will retain good vision (BCVA ≥70 ETDRS letters) in the first-affected eye at 10 years after starting anti-VEGF treatment; yet, one in two patients will have good vision in their better-seeing eye. Moreover, our data suggest that early treatment of nAMD is associated with better visual outcomes.

PurposeThe safety and efficacy of X-82, an orally administered inhibitor of vascular endothelial growth factor (VEGF) and platelet-derived growth factor, was investigated for treatment of wet age-related macular degeneration (AMD) in a phase II clinical trial.MethodsThis phase II, randomised, double-masked, placebo-controlled trial enrolled subjects with a prior diagnosis of exudative AMD having received at least two intravitreal injections of anti-VEGF therapy. Subjects were randomised equally into four groups that received either daily 50mg, 100mg or 200mg dosages of X-82 or a placebo tablet. At each 4-week interval visit for 52 weeks, subjects were to be assessed to determine if rescue treatment was needed with anti-VEGF therapy.Results157 patients were enrolled. Due to gastrointestinal and hepatobiliary adverse events and the fulfilment of the primary endpoint, the trial was stopped prematurely after a second interim analysis. The primary endpoint of non-inferiority of visual acuity compared with placebo was demonstrated in all groups receiving X-82 (p<0.001). There was a dose-dependent trend in the number of injections over a 52-week period, with the 50 mg (n=40), 100 mg (n=39), 200 mg (n=39) and placebo (n=39) group requiring 6.7, 6.0, 4.7 and 8.1 injections, respectively.ConclusionsX-82 oral therapy in combination with pro re nata anti-VEGF injections showed non-inferiority in visual acuity outcomes while achieving a dose-dependent decrease in the number of anti-VEGF injections compared with placebo. Given the limited tolerability and safety issues observed, X-82 does not have a sufficient benefit to risk profile in treatment of patients with AMD.

Background/AimsNeovascular age-related macular degeneration (nAMD) is frequently bilateral, and previous reports on ‘fellow eyes’ have assumed sequential treatment after a period of treatment of the first eye only. The aim of our study was to analyse baseline characteristics and visual acuity (VA) outcomes of fellow eye involvement with nAMD, specifically differentiating between sequential and non-sequential (due to macular scarring in the first eye) antivascular endothelial growth factor treatment and timelines for fellow eye involvement.MethodsRetrospective, electronic medical record database study of the Moorfields AMD database of 6265 patients/120 286 single entries with data extracted between 21 October 2008 and 9 August 2018. The data set for analysis consisted of 1180 sequential, 807 non-sequential and 3410 unilateral eyes.ResultsMean VA (ETDRS letters±SD) of sequentially treated fellow eyes at baseline was significantly higher (63±13), VA gain over 2 years lower (0.37±14) and proportion of eyes with good VA (≥70 letters) higher (46%) than the respective first eyes (baseline VA 54±16, VA gain at 2 years 5.6±15, percentage of eyes with good VA 39%). Non-sequential fellow eyes showed baseline characteristics and VA outcomes similar to first eyes. Fellow eye involvement rate was 32% at 2 years, and median time interval to fellow eye involvement was 71 (IQR: 27–147) weeks.ConclusionThis report shows that sequentially treated nAMD fellow eyes have better baseline and final VA than non-sequentially treated eyes after 2 years of treatment. Sequentially treated eyes also had a greater proportion with good VA after 2 years.

Age-related macular degeneration (AMD) is the most common cause of permanent visual loss in persons over 65 years of age in developed countries. Currently, intravitreal vascular endothelial growth factor (VEGF) inhibitors are the mainstay of the treatment for patients with wet AMD. Despite significant improvements in visual acuity since the beginning of these therapies, challenges in the treatment of wet AMD are still present. Therefore, there are ongoing researches such as sustained-release anti-VEGF therapy, novel generation anti-VEGF agents, viral vectors to modify genetic transcription, and combination therapies. In this review, it is aimed to discuss these emerging therapies.
