Intravitreal Ranibizumab in a Patient with Choroidal Neovascularization Secondary to Multiple Evanescent White Dot Syndrome

Abstract

To report the effect of a single intravitreal injection of ranibizumab in a patient with choroidal neovascularization (CNV) secondary to multiple evanescent white dot syndrome (MEWDS). A 65-year-old woman with visual acuity (VA) 20/40, mild vitreous inflammation, optic disc edema, and white deep retinal round lesions in the right eye underwent fluorescein angiography, indocyanine green angiography, and optical coherence tomography. The diagnosis of MEWDS with peripapillary CNV was made and a single injection of ranibizumab (0.5 mg) was administered. At the 6-month follow-up visit, the VA in the right eye was 20/20, the CNV completely regressed, and the MEWDS findings disappeared. Intravitreal ranibizumab appears to be a safe and effective treatment option in cases of CNV secondary to MEWDS, resulting in fast resolution of the macular edema and regression of the CNV. On the other hand, it is unclear whether the administration of ranibizumab contributed to a prompt regression of MEWDS.
