Antiangiogenic therapy in Sorsby's fundus dystrophy without a mutation in the TIMP-3 gene

Abstract

Case reportThe case is presented of a 32-year-old man referring to metamorphopsia and blurred vision in both eyes for 3 days. Best corrected visual acuity of 20/32 was found in the right eye and 20/25 in the left eye. Fundus examination revealed the presence of drusen-like deposits, suggestive of Sorsby's fundus dystrophy (SFD) and choroidal neovascularization (CNV) bilaterally. The patient received intravitreal ranibizumab. Visual acuity improved to 20/20 in both eyes at 6-month follow-up, and results of fundus examination showed complete regression of neovascularization. No mutations were found in the TIMP-3 gene. DiscussionThe known mutations in TIMP-3 may not be extended to all patients with SFD. The use of intravitreal ranibizumab may be considered as a therapeutic option in CNV secondary to SFD.
