One year outcomes of eyes with polypoidal choroidal vasculopathy with ≥20/40 visual acuity treated with anti-vascular endothelial growth factor agents

PURPOSE: To report the 12 months outcomes of treatment naïve polypoidal choroidal vasculopathy (PCV) in patients with ≥20/40 Snellen's best-corrected visual acuity (BCVA). METHODS: This was a retrospective study including eyes treated with monotherapy of anti-vascular endothelial growth factors (VEGF) agents (bevacizumab, ranibizumab, aflibercept, and ziv-aflibercept) on a pro-re-nata (PRN) protocol. Photodynamic therapy using verteporfin (vPDT) was used as rescue therapy. The primary study objective was change in BCVA at 12 months. Secondary objectives included change in optical coherence tomography parameters: central macular thickness (CMT) and pigment epithelial detachment (PED) height, the mean number of injections, and treatment-free interval at 12 months. RESULTS: A total of 18 eyes of 18 patients (7 males, 11 females) were included. The mean age was 58.0 ± 12.0 years. BCVA at baseline and 12 months were 0.16 ± 0.08 (Snellen equivalent 20/30) and 0.15 ± 0.15 logarithm of the minimum angle of resolution (20/30), respectively. Twelve (66.6%) eyes either improved or maintained BCVA. Mean (±standard deviation [SD]) CMT at baseline and 12 months were 188.2 ± 61.1 μ and 161.7 ± 47.4 μ (P = 0.15), respectively. PED height improved to 236.4 ± 208.7 μ at 12 months (P = 0.05). The mean (±SD) number of injections was 3.28 ± 1.96 with a treatment-free period of 6.83 ± 3.63 months. Three eyes required vPDT (4 treatment sessions; mean: 1.33) as a rescue therapy through 12 months. CONCLUSION: PRN anti-VEGF monotherapy in real-life situations for the treatment of naïve PCV eyes with good visual acuity (≥20/40) achieves maintenance or improvement of visual acuity through 12 months follow-up.
