Abstract

Objectives: Polypoidal choroidal vasculopathy is a common disease in Asia, but it has been less described in the Caucasian population. The aim of this real-life observational study was to describe the diagnostic and therapeutic practices as well as the prognosis in this population. Method: Fifty Caucasian patients with polypoidal choroidal vasculopathy were included in this study. All patients underwent angiography to confirm the diagnosis. Patients were divided into two treatment groups: patients of group 1 only received anti–vascular endothelial growth factor injections and those of group 2 required photodynamic therapy rescue in addition to intravitreal injections in case of suboptimal (anatomically or functionally) response. Clinical (visual acuity, fundus examination), paraclinical (retinal pigment epithelium detachment height and central retinal thickness on optical coherence tomography), and therapeutic (number of intravitreal injections) criteria were analyzed after 24 months. Results: Patient mean age was 73.9 ± 9.1 years, and half of the patients had age-related macular degeneration. In the whole cohort, the initial visual acuity was equivalent to the final visual acuity (59.9 ± 24.0 letters vs 62.5 ± 21.1 letters, p = 0.259). In group 1, the final visual acuity was significantly increased (from 56.9 ± 24.7 letters to 63.4 ± 21.6 letters, p = 0.016), while in group 2, it remained stable (from 61.7 ± 23.4 letters to 61.0 ± 21.4 letters, p = 0.249). The number of intravitreal injections was similar between both groups. Conclusion: In a Caucasian population, polypoidal choroidal vasculopathy seems to have a later onset. A non-standardized management allows stabilizing the functional prognosis. Patients requiring photodynamic therapy rescue have a poorer prognosis.
