A 22-year-old Japanese woman with systemic sarcoidosis had retinal neovascularizations at seven loci with repeated vitreous hemorrhage in her right eye. Oral administration of prednisone was not effective. However, argon laser photocoagulation to the neovascularizations obliterated the neovascular fronds except at the optic nerve head; three months from the treatment, the neovascularization at the optic nerve head regressed spontaneously. No serious complications have occurred, and the vitreous hemorrhage has not recurred for the past two years. From these results, argon laser photocoagulation was thought to be effective for the treatment of retinal neovascularization in sarcoidosis.
