Background: In recent years, major progress has been made in treating the wet form of age-related macular degeneration (AMD) with anti-vascular endothelial growth factors, which reportedly stabilize and improve vision.

Objectives: To examine the effect of dietary supplementation, as recommended by the Age-Related Eye Disease Study 2 (AREDS2), on the number of anti-vascular endothelial growth factor injections administered to patients with wet AMD.

Methods: A retrospective study was conducted with 57 participants (27 participants in the study group and 30 in the control group) receiving injections of anti-vascular endothelial growth factors. The study group received dietary supplements for at least one year before the treatment was initiated, while the control group did not. Primary outcome was the number of injections a patient received over a 3-year period. Secondary outcomes were central macular thickness and visual acuity.

Results: The average number of injections per patient after 3 years was 21.89 ± 7.85 in the study group and 26.00 ± 5.62 in the control group (P = 0.083). Final visual acuities were 0.45 ± 0.45 and 0.8 ± 0.73 (P = 0.09), and final central macular thicknesses were 288.26 ± 55.38 and 313.12 ± 107.36 (P = 0.38) in the study and control groups, respectively.

Conclusions: The average number of injections after 3 years was lower in the study group, but this difference did not reach statistical significance. No statistically significant difference was found in final visual acuity or central macular thickness between the groups.

The prevalence of choroidal nevi associated with choroidal neovascular membrane (CNV) is estimated to range between 0.58% and 8.6% [1]. The pathogenesis of CNV is not completely understood. Researchers have suggested that damage caused to the choroid capillaries above the nevi affects the overlying retinal pigment epithelium and triggers production of angiogenic factors that, in turn, cause the development of CNV [2,3]. Hypoxia and inflammation may be involved in the process. Data have been inconsistent with both theories [4].

Background: Delayed diagnosis of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) adversely affects visual outcome.

Objectives: To identify factors associated with early detection of CNV in the clinic setting.

Methods: Demographic and clinical data and lesion characteristics were retrospectively collected from 76 consecutive AMD patients who had a history of CNV in one eye and presented with CNV in the second eye. These data were evaluated for association with visual acuity (VA) at the time of presentation.

Results: Better VA was associated with a history of CNV in the fellow eye (P < 0.0001), adherence to follow-up every 4 months (P = 0.015), younger age (P = 0.03), smaller lesion (P < 0.0001), and non-subfoveal location (P = 0.048). VA of the fellow eye did not correlate with VA at presentation with CNV.

Conclusions: These data suggest that patients’ experience of CNV, regardless of VA, facilitates early diagnosis in the fellow eye. Adherence to follow-up in the routine clinic setting also facilitates early detection of CNV.
