AbstractOuter retinal tubulations (ORT) are a relatively new finding characterizing outer retinal atrophy. The main aim of the present study was to describe ORT development in advanced age-related macular degeneration (AMD) and to assess its relationship with disease’s severity. Patients with advanced AMD characterized either by macular neovascularization or geographic atrophy, showing signs of outer retinal disruption or retinal pigment epithelium atrophy on structural optical coherence tomography (OCT) at the inclusion examination were prospectively recruited. All the patients underwent complete ophthalmologic evaluation, structural OCT scans and fundus autofluorescence imaging. The planned follow-up was of 3-years. Main outcome measures were ORT prevalence, mechanism of ORT formation, mean time needed for complete ORT formation, best-corrected visual acuity (BCVA), definitely decreased autofluorescence (DDAF) area, questionably decreased autofluorescence (QDAF) area, retinal layer thickness, foveal sparing, number of intravitreal injections. We also assessed the possible role of external limiting membrane (ELM) and Müller cells in ORT pathogenesis. Seventy eyes (70 patients) were included; 43 showed dry AMD evolving to geographic atrophy, while 27 displayed the features of wet AMD. Baseline BCVA was 0.5 ± 0.5 LogMAR, decreasing to 0.9 ± 0.5 LogMAR at the 3-year follow-up (p < 0.01). We detected completely formed ORT in 26/70 eyes (37%), subdivided as follows: 20 eyes (77%) wet AMD and 6 eyes (23%) dry AMD (p < 0.01). ORT took 18 ± 8 months (range 3–35 months) to develop fully. We described the steps leading to ORT development, characterized by progressive involvement of, and damage to the photoreceptors, the ELM and the RPE. Eyes displaying ORT were associated with a smaller QDAF area, less retinal layers damage and lower rate of foveal sparing than eyes free of ORT (p < 0.01). We also described pigment accumulations simulating ORT, which were detected in 16/70 eyes (23%), associated with a greater loss of foveal sparing, increased DDAF area and smaller QDAF area at the 3-year follow-up (p < 0.01). In conclusion, this study provided a description of the steps leading to ORT development in AMD. ELM and Müller cells showed a role in ORT pathogenesis. Furthermore, we described a subtype of pigment hypertrophy mimicking ORT, evaluating its clinical utility.

Background: Age-related macular degeneration (AMD) is the leading cause of blindness and can be classified into two types called atrophic AMD (dry AMD) and neovascular AMD (wet AMD). Dry AMD is characterized by cellular degeneration of the retinal pigment epithelium, choriocapillaris, and photoreceptors. Wet AMD is characterized by the invasion of abnormal vessels from the choroid. Although anti-vascular endothelial growth factor (VEGF) therapy has a potent therapeutic effect against the disease, there is a possibility of chorio-retinal atrophy and adverse systemic events due to long-term robust VEGF antagonism. We focused on hypoxia-inducible factor (HIF) regulation of VEGF transcription, and report the suppressive effects of HIF inhibition against ocular phenotypes in animal models. Many of the known HIF inhibitors are categorized as anti-cancer drugs, and their systemic side effects are cause for concern in clinical use. In this study, we explored food ingredients that have HIF inhibitory effects and verified their effects in an animal model of AMD. Methods: Food ingredients were screened using a luciferase assay. C57BL6/J mice were administered the Garcinia cambogia extract (Garcinia extract) and hydroxycitric acid (HCA). Choroidal neovascularization (CNV) was induced by laser irradiation. Results: Garcinia extract and HCA showed inhibitory effects on HIF in the luciferase assay. The laser CNV model mice showed significant reduction of CNV volume by administering Garcinia extract and HCA. Conclusions: Garcinia extract and HCA showed therapeutic effects in a murine AMD model.

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.

Choroidal thickness measurement results of 124 patients (210 eyes) with age-related macular degeneration (AMD) obtained by enhanced depth imaging of spectral domain optical coherence tomography (EDI-OCT) are presented. There were no significant differences in choroidal thickness between patients with dry and wet AMD forms and healthy people of the same age group (р = 0.67; р = 0.26). A statistically significant choroidal thinning in patients with late AMD stages as compared to each of healthy people and dry and wet AMD patients was found (р < 0.0001).

Background/aimsTo monitor treatment-naïve patients with wet age-related macular degeneration (wet AMD) receiving intravitreal aflibercept (IVT-AFL) in France.MethodsRAINBOW (Real life use of intravitreal Aflibercept In FraNce - oBservatiOnal study in Wet age-related macular degeneration) is an ongoing, observational, retrospective and prospective 4-year study to assess visual (primary), anatomical and safety outcomes following IVT-AFL treatment in wet AMD patients. We report the interim 12-month outcomes in patients who have already been enrolled.ResultsSafety data were analysed from 586 patients (safety analysis set); and effectiveness data were analysed from 502 patients with at least one follow-up (full-analysis set) and from 353 patients with visual acuity data at baseline and month 12. The mean (SD) best-corrected visual acuity (BCVA) was 56.7 (18.2) letters and the mean (SD) central retinal thickness (CRT) was 395.6 (140.5)µm at baseline. Most patients (76.9%) received a loading dose (first three injections within 90 days). The mean (SD) number of IVT-AFL injections over 12 months was 6.0 (2.1) and 6.6 (1.8) (patients who received a loading dose). The mean (SD) change in BCVA was 5.5 (15.0) letters and 6.8 (14.5) letters (patients who received a loading dose) at month 12 (p<0.001 vs baseline). The mean (SD) CRT reduction was –108.7 (146.8)µm and –116.4 (150.4)µm (loading dose) at month 12 (p<0.001 vs baseline). Overall, 118 (20.1%) patients experienced at least one treatment-emergent adverse event (TEAE), 1.2% experienced ocular TEAEs and 3.9% experienced serious AEs.ConclusionThis 12-month interim analysis showed that IVT-AFL was associated with sustained improvements in a real-world setting. The RAINBOW results are consistent with the VIEW clinical studies.Trial registration numberNCT02279537 Pre-results.

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 purpose of this article is to examine the efficacy of macular hole repair in eyes with coexisting dry age-related macular degeneration (AMD). Methods: A retrospective analysis was performed of charts of 25 patients (27 eyes) diagnosed with mild to moderate dry AMD who underwent macular hole repair via 25-gauge pars plana vitrectomy between 2014 and 2016. Data of interest included anatomic failure rates, complication rates, and best-corrected visual acuity (BCVA) preoperatively, and at 1 month, 3 months, 6 months, and 12 months postoperatively. When available, data at each patient’s most recent visit were also analyzed. Results: Macular hole repair resulted in a statistically significant ( P < .05) visual improvement postoperatively, with BCVA increasing from 20/141 preoperatively to 20/33 1 year postoperatively. Mean BCVA at most recent visit was 20/41. Mean duration of follow-up was 13 months (range, 1-39 months). One of 27 (3.7%) macular holes failed to close after vitrectomy. One of 27 eyes (3.7%) progressed from dry to wet AMD. Four of 27 additional eyes (18.5%) were noted to have worsening of their AMD on exam over the course of follow-up. Conclusions: Macular hole repair in patients with coexisting dry AMD leads to a significant improvement in visual performance and has a low risk of failure or complication.
