Idiopathic dilated episcleral vessels (Radius-Maumenee syndrome): case report.

Radius-Maumenee syndrome comprises idiopathic dilated episcleral vessels that are usually associated with glaucoma. The case described herein is of a male patient, 69 years old, with chronic dilation of the episcleral vessels and glaucoma in his left eye, with no history of systemic disease. Visual acuity and fundoscopy were normal in both eyes. Tonometry measured 14 mmHg in the right eye and 25 mmHg in the left. Computed tomography angiography (CTA) was negative for carotid-cavernous fistula. The intraocular pressure of the left eye decreased to 20 mmHg with clinical treatment without regression of episcleral venous dilation. Trabeculectomy normalized the intraocular pressure and reduced the vessels. There was choroidal effusion on day 16 of the postoperative period, which resolved with corticosteroids. Although choroidal effusion can occur, the efficacy of trabeculectomy in controlling glaucoma and the reduction of episcleral vessels are clearly demonstrated.
