Abstract

Purpose: To describe the clinical characteristics and visual outcomes of neovascular age-related macular degeneration (NV-AMD) patients with irregular pigment epithelium detachment (PED) and non-resolving subretinal fluid (SRF) despite continuous monthly injections of anti-vascular endothelial growth factor (VEGF). Methods: This is a retrospective case series, including NV-AMD patients treated in a tertiary academic practice. Inclusion criteria were NV-AMD diagnosis, with irregular PED, and non-resolving SRF treated with continuous monthly anti-VEGF intravitreal injections. Data collection included best corrected visual acuity (BCVA), central macular thickness (CMT), sub-foveal choroidal thickness (SFCT), and type and location of PED as seen on optical coherence tomography (OCT). Results: A total of 738 patients with NV-AMD underwent anti-VEGF injections during the follow-up period and 20 eyes of 19 patients (14 females and 5 males) met the inclusion criteria. Average age was 81.7 ± 6.6 years, mean follow-up time was 32.1 ± 23.5 months, and mean number of injections was 31.3 ± 24.2. Mean VA was 0.26 ± 0.21 logMAR (Snellen 20/36) at baseline versus 0.20 ± 0.23 logMAR (Snellen 20/32) at the end of the follow-up (P = 0.28). All eyes presented with sub-foveal, type 1 macular neovascularization (MNV). Average sub-foveal choroidal thickness changed from 189.70 ± 68.46 μm at baseline to 169.00 ± 63.06 μm (P < 0.001) at last follow-up. Conclusion: Patients with type 1 NV-AMD, irregular PED, and non-resolving SRF and under continuous treatment of monthly anti-VEGF injections may maintain good visual acuity after long period of time.
