Comparative analysis of polypoidal choroidal vasculopathy with and without hemorrhage treated by anti-VEGF monotherapy

Purpose Visual function and treatment response after anti-vascular endothelial growth factor monotherapy were compared between polypoidal choroidal vasculopathy (PCV) with and without hemorrhage. Methods We conducted a retrospective, observational study (mean, 26 months) for 49 eyes of 49 treatment-naive patients with PCV. Patients were classified into PCV with hemorrhage (26 eyes) or without hemorrhage (23 eyes). PCV with massive hemorrhage subgroup has four or more disc-hemorrhagic areas and included five eyes. Results There were no significant differences in patient age, sex, systolic blood pressure, diastolic blood pressure, presence of choroidal vascular hyperpermeability, number of polyps, maximum polyp size, lesion area, and presence of pigment epithelium detachment (PED) between the two groups. Except for the course of PCV-related hemorrhage, treatment number and its response were similar between the groups. Best-corrected visual acuity at the last visit in PCV with hemorrhage was 0.33 ± 0.51 logMAR (20/41) comparable with 0.28 ± 0.41 logMAR (20/38) without hemorrhage at the last visit ( p = 0.944). Maximum polyp size in massive hemorrhagic PCV was significantly larger (314.6 ± 111.4 μm) than that of small hemorrhagic PCV (229.0 ± 119.1 μm; p = 0.037). All PCV with massive hemorrhage was accompanied by large hemorrhagic PED. Conclusion There were no significant differences in the baseline characteristics, treatment intervention, or suppression of disease activity between PCV with and without hemorrhage. Final visual acuity of PCV did not differ with or without hemorrhage. Development of massive hemorrhaging in PCV may be associated with both large polyps and hemorrhagic PED.
