LATE RECURRENCE OF CHOROIDAL NEOVASCULARIZATION IN PATIENTS WITH MULTIFOCAL CHOROIDITIS: CLINICAL SURVEILLANCE IN PERPETUITY

PURPOSE: To report a very late recurrence of choroidal neovascularization (CNV) in elderly patients with noninfectious multifocal choroiditis (MFC). METHODS: Retrospective case series of patients with MFC with confirmed recurrence of CNV. Choroidal neovascularization was diagnosed with multimodal imaging, including optical coherence tomography angiography. Multifocal choroiditis-associated CNV eyes were treated with intravitreal injections of anti-vascular endothelial growth factor medication. RESULTS: Four eyes of three patients were included in our study, with a mean (range) age of 73 years (67-78). The period between the original CNV and the recurrence was 53 years, with a range of 48-60 years. The mean number (range) of injections given after the late recurrence per eye was 7 (5-11). The mean duration (range) of follow-up post-treatment initiation was 93 (40-122) weeks. All eyes improved to 20/30 visual acuity or better at 6 months after initial treatment. CONCLUSION: Patients with MFC are never exempt from recurrent CNV, warranting follow-up in perpetuity. Age-related factors are important to consider which may increase the susceptibility for activating MFC-associated CNV in elderly people. Macular neovascularization could respond to a standard approach to management, in these patients with MFC, by a judicious use of intravitreal injections of anti-vascular endothelial growth factor therapy.
