Optical Coherence Tomography Prognostic Factors in Age-Related Macular Degeneration Patients with Peripapillary Choroidal Neovascularization

Abstract

Purpose: The aim of the study was to investigate the correlation between optical coherence tomography (OCT) findings and visual acuity outcomes after treatment with intravitreal bevacizumab (IVB) injections for age-related macular degeneration (AMD) patients with peripapillary choroidal neovascularization (PPCNV). Methods: The study involved a retrospective case series of consecutive patients diagnosed with PPCNV secondary to AMD. All patients were treated with IVB injections with a follow-up time of 1 year. Data collected included best-corrected visual acuity (BCVA) and automated and manually measured OCT parameters. Results: A total of 68 eyes were diagnosed with PPMV. Of them, 30 eyes of 30 patients aged 84.3 ± 6.9 years of which 63.3% female gender were included. Baseline BCVA was 0.46 ± 0.62 logMAR (Snellen 20/57), average choroidal thickness was 193.2 ± 22 μm, and mean number of IVB injections was 7.2 ± 1.9. After 1 year, BCVA was 0.56 ± 0.78 logMAR (Snellen 20/72) (p = 0.28). Eyes with greater central retinal thickness (r = −0.36, p = 0.05), greater subretinal hyper-reflective material (SHRM) area (r = −0.37, p = 0.05), and greater sub-retinal fluid (SRF) area (r = −0.73, p < 0.001) had a significantly smaller improvement in BCVA. Eyes with pigment epithelium detachment (PED) (0.68 ± 0.90 vs. 0.21 ± 0.12, p = 0.03) had a significantly worse BCVA. Conclusions: Our data suggest that AMD-related PPCNV with greater foveal thickness, PED size, SHRM, and SRF areas have worse final BCVA prognosis.
