对40例57眼原发性慢性闭角型青光眼(PCACG)和正常对照组30例60眼,进行了房水荧光素浓度曲线的测定。结果显示,PCACG房角关闭≥:180°组,房水荧光素下降率比对照组减少30.21%,所致视功能损害为青光眼早期和中期改变。而房角关闭≥270°组,房水荧光素下降率比对照组减少58.95%,所致视功能损害主要是青光眼晚期改变。证明PCACG房角关闭范围越大,房水荧光素下降率越低,眼压越高,视功能损害也就越严重。 Forty-seven eyes of 40 eyes with chronic angle-closure glaucoma (PCACG) and 60 eyes of 30 normal controls were enrolled in this study. Fluorescein concentration curve was measured. The results showed that the rate of fluorescein in aqueous humor decreased by 30.21% in PCACG group than that in the control group (180 ° group). The damage of visual function was the change of early and middle glaucoma. The room angle closed ≥ 270 ° group, the aqueous fluorescein decreased rate of 58.95% reduction compared with the control group, resulting in visual impairment mainly in the late glaucoma. Proof PCACG angle off the larger the room, the lower the rate of aqueous fluorescein, the higher the intraocular pressure, visual function impairment is also more serious.
