title: A case of retinitis pigmentosa associated with Coats' syndrome.
abstract: The association of bilateral retinitis pigmentosa with Coats' syndrome is reported. Four lesions of vascular telangiectasis with yellowish exudates were treated by xenon photocoagulation or cryocautery. Seven months later, new vascular changes occurred in another quadrant of the fundus. Since xenon photocoagulation could not be performed because of the patient's aversion to pain, argon laser photocoagulation was used but found ineffective. Cryocautery was necessary to treat the exudation over one quadrant, though xenon photocoagulation was effective in small lesions.
