The authors report the clinical course of two cases of autosomal recessive bestrophinopathy (ARB) complicated by choroidal neovascularization (CNV). One patient presenting with a novel BEST1 mutation (c.658 C>T, p.Gln220*) underwent anti-vascular endothelial growth factor therapy. Response to treatment was documented on optical coherence tomography angiography (OCTA). Despite initial response to treatment, recurrent CNV exudation with progressive subretinal fibrosis was observed. In the second patient, the CNV was not treated and spontaneous regression was observed. This report indicates that the clinical course of CNV in ARB may vary considerably, ranging from spontaneous regression to progressive subretinal fibrosis despite intervention.
