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.
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).
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.
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.
眼眶肿瘤、颈动脉海绵窦瘘及其他眼眶阻塞性病变患者可出现巩膜表层血管扩张。作为一种特发现象，巩膜表层血管扩张可能与继发性开角型青光眼有关。
我们报告一例59岁患者，有继发性开角型青光眼病史及巩膜表层血管扩张5年（拉迪厄斯-马梅内综合征）。
在这些患者中，巩膜表层血管压力升高，因此施莱姆管的房水流出减少。这导致眼压升高和继发性青光眼。
这种情况下的治疗选择包括降低眼压的药物治疗或显微手术窦切开术，以降低从施莱姆管到巩膜表层血管的压力梯度。
