The use of argon laser photocoagulation in a case of vogt coyanagi harada with choroidal neovascular membrane.

In this study, we presented the outcome of the treatment of extrafoveal choroidal neovascular membrane (CNVM) with argon laser photocoagulation in a patient with Vogt-Koyanagi-Harada (VKH) Syndrome. While a 37-year-old female patient was being followed in our clinic for 7 months with the diagnosis of possible VKH syndrome with only ocular findings, the patient was admitted to our clinic with the complaint of blurred vision, bilateral anterior uveitis and was receiving systemic cyclosporine (200 mg/day) treatment. Visual acuity was 0.9 in the right eye and 0.7 in the left eye. In the fundoscopic examination of the right eye, CNVM of approximately 1 optic disc diameter surrounded by hemorrhage was detected in the upper nasal optic disc, and retinal pigment epithelial (RPE) changes were present in the macula. Focal argon laser photocoagulation was applied to the CNVM area. While visual acuity was 0.9 in the right eye at the 3rd month of laser treatment, fundus fluorescein angiography (FFA) showed that the leakage of CNVM disappeared in the area where the focal laser was applied, and RPE atrophy was detected in the same area. KNVM is a rare but serious complication of Vogt Koyanagi-Harada Syndrome. Argon laser photocoagulation may be a useful and effective treatment option for extrafoveal CNVM in these patients.
