Corticosteroids Decrease the Incidence and Activity of Choroidal Neovascularization in Patients with Punctuate Inner Choroidopathy or Multifocal Choroiditis

PURPOSE: To assess the effect of corticosteroids (CS) on choroidal neovascularization (CNV) occurrence and recurrence of activity over 2 years in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC). METHODS: Retrospective longitudinal study. Previous use of CS was analyzed between group without CNV and group with CNV occurrence and recurrence. RESULTS: Thirty-six patients were included. Patients with CNV were less likely to have received CS in the 6 months following PIC or MFC diagnosis (17% versus 65%, p-value = 0.01). Patients with CNV who had a recurrence of neovascular activity were less likely to have received a previous CS therapy (20% versus 78%; odds ratio = 0.08, p-value = 0.005). CONCLUSIONS: This study suggests that patients with PIC and MFC should be treated by CS to prevent CNV development and decrease CNV recurrences.
