摘　　要：目的探讨青光眼与视网膜缺血性疾病间的关系。方法回顾因眼底疾病就诊，同时发现青光眼的患者7例，分析其导致眼底缺血的病因。结果就诊时眼底病诊断为视网膜静脉阻塞4例，缺血性视神经病变者2例，低灌注视网膜病变1例。经颅多普勒超声检查显示均无明显颈内、颈总动脉阻塞。双眼眼动脉血流速度无明显差异。结论青光眼高眼压可导致眼压与睫状后动脉压、视网膜中央动脉压的平衡失调，导致眼部血流灌注不足，出现缺血性视神经视网膜病变。因此，当患者发生缺血性视神经视网膜病变时，不可忽视青光眼的可能。Objective To investigate the relationship between glaucoma and retinal ischemic diseases. Methods Review 7 cases of retinal ischemic diseases, in which we also diagnosed as glaucoma. Analyze the causes of ischemia. Results In the 7 cases, 4 were retinal vein obstruction, 2 were ischemic optic neuropathy, and 1 was hypoperfusion retinopathy. Transcranial Doppler ultrasonography exhibited no obvious occlusion in internal and common carotid artery. There was no significant difference in blood velocity between the ophthalmic arteries. Conclusions Intraocular hypertension causes disequilibrium among intraocular pressure, the blood pressure of posterior ciliary arteries and central retinal arteries. Subsequently, ocular perfusion decreases and ischemic optic neuropathy and retinopathy turn out. Therefore, when ischemic optic neuropathy and retinopathy occurring, probability of glaucoma cannot be ignored.
