Purpose. To evaluate the effect of smoking on the outcome of antivascular endothelial growth factor (VEGF) therapy in patients with neovascular age-related macular degeneration (nAMD). Methods. This retrospective case-control study included 64 eyes in 59 patients with treatment-naïve nAMD. Smoking habits were obtained from hospital records and patient recall. The patients were divided into ever-smokers and never-smokers. The patients were treated with ranibizumab or aflibercept for at least 1 year. Outcome measures were best-corrected visual acuity (BCVA), central retinal thickness (CRT) at the fovea, subfoveal choroidal thickness (SCT), and number of injections received. Results. There were no statistically significant differences in BCVA, CRT, or SCT changes between ever-smokers and never-smokers. The number of injections received was significantly higher in ever-smokers with a history of heavy smokers (never-smokers vs. heavy smokers: 5.3 ± 2.6/year vs. 7.3 ± 2.5/year; P=0.048 and mild smokers vs. heavy smokers: 5.2 ± 2.5/year vs. 7.3 ± 2.5/year; P=0.043). There was no significant difference in the baseline CRT or presence of atrophic retinal pigment epithelium in the fellow eyes of patients with nAMD according to smoking status; however, the baseline CRT in eyes with nAMD was significantly thinner in ever-smokers than in never-smokers (P=0.02). Conclusion. The anti-VEGF therapy was frequently required in nAMD patients with a history of heavy smoking. Heavy smoking could cause poor therapeutic response in nAMD patients.

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.

ObjectiveTo compare the visual outcomes of intravitreal antivascular endothelial growth factor (anti-VEGF) injections in neovascular age-related macular degeneration (nAMD), diabetic macular oedema (DMO) and retinal vein occlusion (RVO) in a real-world setting.Methods and analysisRetrospective analysis of data from the Tasmanian Ophthalmic Biobank database. The median change in best-corrected visual acuity (BCVA) between baseline and 12 months post initiating intravitreal anti-VEGF treatment were compared between the three diseases. Final BCVA, central macular thickness (CMT), cumulative number of injections and overall predictors of change in BCVA and CMT were also determined.ResultsAt 12 months, change in BCVA was significantly different between nAMD, DMO and RVO cohorts (p=0.032), with lower median change for DMO (2 letters, range −5 to 20) than for RVO (11 letters, range −20 to 35). Likewise, CMT change was significantly different between the three cohorts (p=0.022), with a smaller reduction in CMT in DMO (−54 µm, range −482 to 50) than RVO patients (−137 µm, range −478 to 43; p=0.033). Total number of injections received (p=0.028) and final BCVA score (p=0.024) were also significantly different between the groups. Baseline BCVA was a negative predictor (p=0.042) and baseline CMT a positive predictor (p<0.001) of outcome. After adjusting for baseline BCVA and CMT, diagnosis of nAMD or RVO was a predictor of visual improvement compared with the DMO.ConclusionsAt the end of 12 months, nAMD and RVO cohorts had the greatest improvement in BCVA, however the final BCVA for DMO was significantly better than for nAMD.

Intravitreal antivascular endothelial growth factor (VEGF) agents are widely used to treat ocular conditions but the benefits and harms of these treatments are uncertain. We conducted a systematic review to compare the effects of aflibercept, bevacizumab and ranibizumab on best-corrected visual acuity (BCVA) changes, quality of life and ocular or systemic adverse events in patients with neovascular age-related macular degeneration (NVAMD), diabetic macular oedema (DME) and central or branch retinal vein occlusion (RVO). We searched published and unpublished literature sources to February 2017 for randomised controlled trials and cohort or modelling studies reporting comparative costs in the USA. Two reviewers extracted data and graded the strength of the evidence using established methods. Of 17 included trials, none reported a clinically important difference (≥ 5 letters) in visual acuity gains between agents. Nine trials provide high-strength evidence of no difference between bevacizumab and ranibizumab for NVAMD. Three trials provide moderate-strength evidence of no difference between bevacizumab and ranibizumab for DME. There was low-strength evidence of similar effects between aflibercept and ranibizumab for NVAMD, aflibercept and bevacizumab for RVO and all three agents for DME. There was insufficient evidence to compare bevacizumab and ranibizumab for RVO. Rates of ocular adverse events were low, and systemic harms were generally similar between groups, although 1 DME trial reported more arterial thrombotic events with ranibizumab versus aflibercept. Overall, no agent had a clear advantage over another for effectiveness or safety. Aflibercept and ranibizumab were significantly less cost-effective than repackaged bevacizumab in two trials.

Purpose: This article studies visual outcome and frequency of antivascular endothelial growth factor (anti-VEGF) injections continued in patients with neovascular age-related macular degeneration (AMD) who had an earlier vitrectomy for postinjection endophthalmitis. Methods: A retrospective interventional study was conducted reviewing our database for patients with a diagnosis of endophthalmitis in the course of anti-VEGF injections. Endophthalmitis diagnosis was made on clinical examination of pain, rapid decrease in visual acuity (VA), conjunctival hyperemia, hypopyon, and vitritis. In all eyes, core vitrectomy with intravitreal antibiotics was performed. Spectral-domain optical coherence tomography was performed monthly before and after surgery during follow-up. Anti-VEGF injections were continued after surgery in all cases. Results: Eight eyes with postinjection endophthalmitis were included. Mean VA immediately before endophthalmitis was 20/50 Snellen with a mean of 19 intravitreal anti-VEGF injections ( P = .45). At time of endophthalmitis diagnosis, mean VA was 20/1000 (range, 20/2000-20/200). Mean time from injection to when the patient noted first symptoms was 4.3 days (range, 1-8 days). Mean time from first symptoms to surgery was 12 hours (range, 2.5-26 hours). Final mean VA at the end of follow-up (range, 12-84 months) did not statistically differ from VA at the visit immediately before endophthalmitis diagnosis ( P = .69). Mean frequency of injections after vitrectomy did not significantly differ from the presurgical course of treatment ( P =.97). Conclusions: Anti-VEGF treatment might be continued after vitrectomy for endophthalmitis and results in satisfactory anatomical and visual outcome. Surgery did not influence the frequency of anti-VEGF injections for neovascular AMD.

Background: We aimed to evaluate the comparative efficacy and safety of anti–vascular endothelial growth factor (anti-VEGF) monotherapy to identify its utilization and prioritization in patients with neovascular age-related macular degeneration (nAMD).Methods: Eligible studies included randomized controlled trials comparing the recommended anti-VEGF agents (ranibizumab, bevacizumab, aflibercept, brolucizumab, and conbercept) under various therapeutic regimens. Outcomes of interest included the mean change in best-corrected visual acuity (BCVA), serious adverse events, the proportion of patients who gained ≥15 letters or lost &lt;15 letters in BCVA, the mean change in central retinal thickness, and the number of injections within 12 months.Results: Twenty-seven trials including 10,484 participants and eighteen treatments were identified in the network meta-analysis. The aflibercept 2 mg bimonthly, ranibizumab 0.5 mg T&amp;E, and brolucizumab 6 mg q12w/q8w regimens had better visual efficacy. Brolucizumab had absolute superiority in anatomical outcomes and a relative advantage of safety, as well as good performance of aflibercept 2 mg T&amp;E. The proactive regimens had slightly better efficacy but a slightly increased number of injections versus the reactive regimen. Bevacizumab had a statistically non-significant trend toward a lower degree of efficacy and safety.Conclusion: The visual efficacy of four individual anti-VEGF drugs is comparable. Several statistically significant differences were observed considering special anti-VEGF regimens, suggesting that brolucizumab 6 mg q12w/q8w, aflibercept 2 mg bimonthly or T&amp;E, and ranibizumab 0.5 mg T&amp;E are the ideal anti-VEGF regimens for nAMD patients. In the current landscape, based on the premise of equivalent efficacy and safety, the optimal choice of anti-VEGF monotherapies seems mandatory to obtain maximal benefit.
