Summary
Background Dilated episcleral vessels may be observed in patients with orbital tumors, carotid-cavernous-sinus fistula and other orbital obstructive lesions. As an idiopathic phenomenon dilated episcleral vessels may be associated with secondary open-angle glaucoma.
Patient We report on a 59-year-old patient with a history of secondary open-angle glaucoma and dilated episcleral vessels for 5 years (Radius-Maumenee syndrome).
Results In these patients, the pressure of the episcleral vessels is elevated and therefore the outflow from Schlemm's Canal is reduced. This leads to elevated intraocular pressure and secondary glaucoma.
Conclusion Treatment options in this condition include medication to lower the intraocular pressure or microsurgical sinusotomy to reduce the pressure-gradient from Schlemm's Canal to the episcleral vessels.
