摘要
本文对55例视网膜中央动脉阻塞的病因、临床表现和视力预后进行了分析。现将结果报如下:
The pathogenesis and visual prognosis in 55 cases of central retinalartery occlusion (CRAO) were analysed. Included were 30 males and 25females. Their average age was 45.5 years of whom, 56.36% (51/55) wereCRAO, 38.18% (21/55) were BRAO, and 5.46% (3/55) were cilioretinal arteryocclusion. The time of following ranged from one month to 19 years(mean, 4 years and 3 months). 27 patients of this group had hypertensionand 32 patients had retinal arteriosclerosis. The patients generally presen-ted presymptom before blockage of the central retinal artery. The pre-valence rate of blindness was 70.59% in CRAO, 11.76% in BRAO. The visualprognosis appears to correlate with the duration of visual impairment. Thevisual acuity apparently improved in the cases examined and treatedWithin 4 hours duration of visual loss.
