PURPOSE: This study aimed to investigate the effect of bevacizumab on pigment epithelial detachment (PED) in occult choroidal neovascularization (CNV) in patients with age-related macular degeneration (AMD) and to determine predictive factors. METHODS: 73 eyes of patients with AMD and PED due to CNV with subretinal and/or intraretinal fluid were assessed. Patients were treated with 1.25 mg of intravitreal bevacizumab. RESULTS: After 30.6 weeks, the mean visual acuity (VA) increased from 0.53 to 0.49 logMAR (p=0.170). The mean PED height decreased from 354.4 μm to 277.4 μm (p=0.004). Although 53.4% of the eyes showed a reduction in PED, this did not correlate with a significant change in VA. Predictive factors were a high baseline PED and VA <0.32. CONCLUSION: Half of the patients showed PED flattening. Especially in patients with distinctive PED, a response to intravitreal bevacizumab may be expected. This therapy can stabilize VA, but PED flattening does not essentially correlate with an increase in VA.
