Abstract Purpose: To study long-term clinical outcomes in patients with submacular hemorrhage (SMH) and/or vitreous hemorrhage (VH) associated with neovascular age-related macular degeneration (nAMD), who received pars plana vitrectomy (PPV) followed by anti-vascular endothelial growth factor (VEGF) therapy.Methods: In this retrospective case series, 25 eyes with SMH and/or VH associated with nAMD were treated by PPV and followed for at least 24 months. When exudative changes were unresolved or recurred after PPV, additional intravitreal anti-VEGF therapy was given. Results:Mean best-corrected visual acuity (BCVA) of all patients improved significantly at 1, 3, 6, 12, 18 and 24 months (P<0.01) post-PPV and at the final visit (P<0.05). Mean BCVA of 13 eyes with anti-VEGF therapy improved significantly at 1 (P<0.05), 3, 6, 12 (P<0.01), 18 and 24 months (P<0.05), while 12 eyes without anti-VEGF therapy improved at 1, 3 and 6 months (P<0.05) only. Average duration from initial PPV to anti-VEGF therapy initiation was 7.54±9.9 months. Five of 13 eyes (38.5%) with anti-VEGF therapy maintained dry macula for more than 1 year after the last injection. Conclusions:　In patients with SMH and VH caused by nAMD, administering intravitreal anti-VEGF therapy when exudative changes are unresolved or recur after PPV maintains improved visual acuity long term.

This retrospective cross-sectional cohort study describes the long-term visual and anatomic outcomes of anti-vascular endothelial growth factor (VEGF) treatment using a treat and extend (TAE) regimen. The cohort consisted of 224 treatment-naïve eyes with age related macular degeneration (NV-AMD) from 202 patients that were treated with anti-VEGF agents bevacizumab, ranibizumab, and aflibercept using a TAE regimen by four physician investigators in a large urban referral center from 2008-2015. Subjects were evaluated for visual acuity, injection frequency and optical coherence tomography (OCT). Over a seven-year follow-up period (mean 3.4 years), an average 20.2 ± 14.7 injections were administered per patient. Visual acuity was 0.70 logMAR (20/100 Snellen) at the first visit and 0.67 logMAR (20/93 Snellen) at the final visit, with 74% of eyes maintaining or gaining more than 2 lines of vision. Longterm, 45.1% of eyes achieved 20/50 or better, while 27.1% were 20/200 or worse. 61.2% received monotherapy with no difference in visual acuity outcomes or injection frequency between the agent used. OCT analysis showed decreased fluid from initial to final follow-up visit: 70.1% to 15.6% with sub-retinal fluid (SRF) and 47.3% to 18.8% with intraretinal fluid (IRF) with no difference between the agent used. This study demonstrates that most patients (74%) improve or maintain visual acuity gains long-term using a TAE model with a significant portion (45.1%) achieving 20/50 or better with sustained treatment.

Purpose: The aim of this study was to determine whether multiple intravitreal injections of anti-vascular endothelial growth factor (VEGF) drugs for age-related macular degeneration (AMD) exacerbate systemic arteriosclerosis, using the cardio-ankle vascular index (CAVI) and intima-media thickness (IMT). Methods: We analyzed the data of 45 AMD patients who received intravitreal injections of anti-VEGF drugs (ranibizumab and/or aflibercept) and underwent systemic evaluations at baseline and after treatment. Reevaluation was conducted at ≥12 months from the initial treatment. Results: The total number of intravitreal injections of overall anti-VEGF drugs was significantly correlated with Δserum cystatin C. The cumulative number of aflibercept injections was identified as an independent protective factor for ΔCAVI. An increase in the cumulative number of intravitreal injections of overall anti-VEGF drugs was identified as a protective factor for Δmean IMT. Conclusion: Repeated intravitreal injections of an anti-VEGF drug for AMD may lead to morphological and functional changes in large arteries.

AimsTo evaluate outcome of anti-vascular endothelial growth factor (VEGF) therapy for the treatment of neovascular age-related macular degeneration (nAMD) in the real-life setting and to compare incidence of ocular serious adverse events (SAE) after injections administered by nurses and physicians.MethodsRetrospective, single-centre study. Medical records of patients receiving anti-VEGF treatment for nAMD between 2008 and 2013 with three-loading-dose regimen were evaluated. Outcome measures were baseline visual acuity (VA), change in VA, number of intravitreal injections, incidence of ocular SAE and patients’ baseline characteristics affecting VA change. In addition, the number of injections per 1000 citizens living in the serving area and per individuals over 65 years old were estimated.Results1349 eyes in 1117 patients received a total of 11 562 intravitreal anti-VEGF injections. Twenty-one per cent of patients received treatment for both eyes. The mean baseline Snellen VA was 0.32. The mean change of VA from baseline was +2, +2 and ±0 Early Treatment Diabetic Retinopathy Study letters and the mean numbers of injections were 5.7, 4.7 and 4.9 at years 1, 2 and 3, respectively. There was a negative correlation between baseline VA and change of VA. Incidence of endophthalmitis was 0.086%. No difference in the incidence of ocular SAE was identified between injections given by nurses or by physicians. The number of intravitreal injections per all citizens was 9 per 1000 inhabitants and 45 per 1000 inhabitants over 65 years.ConclusionThe VA was maintained at the baseline level (±0 letters) with the mean of 15.3 anti-VEGF injections in real-world clinical practice during 3-year follow-up.

Purpose: To identify outpatient treatment patterns of patients with exudative age-related macular degeneration (AMD) who received approved anti–vascular endothelial growth factor (VEGF) therapy, using real-world data from hospitals in Japan. Methods: A hospital claims database was retrospectively reviewed for patients diagnosed with exudative AMD who were treated with anti-VEGF therapy in the outpatient setting between January 2010 and December 2012. Within a treatment period of at least 12 months, the frequency of anti-VEGF injections and AMD-related visits, and time intervals between AMD-related visits and anti-VEGF injections were captured for patients who had neither cataracts nor glaucoma. “Loading dose regimen” was defined as the first 2 or 3 monthly doses and “PRN maintenance regimen” (where PRN=pro re nata) was defined as the entire period of time after the loading doses had been administered. Results: Claims data were collected from a total of 219 patients from 13 of 126 hospitals: 217 treated with ranibizumab (8 received pegaptanib as well), 2 with aflibercept. Of these, 68 patients were treated for at least 12 months (all with ranibizumab PRN), and 29 had neither cataracts nor glaucoma and were included in the treatment pattern analysis. These 29 patients received a mean of 3.8 injections in the first 12 months and another 2.5 injections in the second 12 months of treatment. The average number of all outpatient visits was 16.1 in the first 12 months and 13.7 in the second 12 months, and an average of 11.6 days elapsed between injections and the previous outpatient monitoring visits using a PRN schedule. Conclusion: In a real-world setting in Japan, anti-VEGF PRN injections are administered less frequently than in clinical trials, and with time between monitoring and re-injection visits. Nonetheless, patients still visit the hospital frequently, which can significantly burden patients, caregivers, and healthcare providers.
