초록
A 68-year-old woman presented with a visual field defect in her right eye. The fundus of her right eye showed multiple telangiectatic vessels, retinal hemorrhages, and subretinal exudates in the inferior peripheral retina. Nine months later, the subretinal exudates extended to the fovea despite treatment with laser photocoagulation. Cryotherapy was not possible at the time because of the posterior location of the retinal telangiectatic vessels. She was treated with a combination of photodynamic therapy (PDT) and intravitreal bevacizumab injection: three injections were given at 2-month intervals. After this combined therapy, her right fundus revealed a significant regression of abnormal retinal vessels and subretinal exudates. A fluorescein angiography showed no leakage from the abnormal retinal vessels. At 9 months after the combined therapy, she was able to maintain a stable visual acuity and visual field. This is the first case report that demonstrates the efficacy of the combined treatment of PDT and intravitreal bevacizumab injection in Coats's disease. This combined therapy is a kind of treatment modality for adult Coats’ disease in cases which cryotherapy cannot be employed and are refractory to laser photocoagulation.
Abstract

The fundus of her right eye showed multiple telangiectatic vessels, retinal hemorrhages, and subretinal exudates in the inferior peripheral retina. Nine months later, the subretinal exudates extended to the fovea despite treatment with laser photocoagulation. Cryotherapy was not possible at the time because of the posterior location of the retinal telangiectatic vessels. She was treated with a combination of photodynamic therapy (PDT) and intravitreal bevacizumab injection: three injections were given at 2-month intervals. After this combined therapy, her right fundus revealed a significant regression of abnormal retinal vessels and subretinal exudates. A fluorescein angiography showed no leakage from the abnormal retinal vessels. At 9 months after the combined therapy, she was able to maintain a stable visual acuity and visual field.
