摘要
以正常人99眼和青光眼患者146眼为研究对象,用Humphrey视野计的黄斑光阈值程序进行研究.结果:早期青光眼与正常人相比黄斑敏感性有明显下降,且随病情进展黄斑光阈值更进一步降低.青光眼各象限黄斑光阈值与正常人相比均明显下降,青光眼黄斑光阈值上方的敏感性明显低于下方结果表明早期无视野缺损的青光眼的黄斑光阈值升高是视神经节细胞功能紊乱的表现之一利用这一特点可以发现更为早期的青光眼,对可疑青光眼患者进行黄斑光阈值的检查,将提高青光眼的早期诊断率.
Both normal subjects and glaucoma patients contributed respectively 30 eyes serving as our research objects, which were studied through the macular threshold program of Humphrey Field Analyzer. As a result, the macular sensitivity was significantly low in the early-glaucoma patients when compared with the normal subjects and the macular threshold dropped further with the ongoing of the disease; the macular thresholds of glaucoma at any stage, in contrast to that of the normal, were all markedly low, with the superior sensitivity being lower than the inferior one. The result showed that the rising macular threshold of early glaucoma without visual field defect is one of the signs for the cell function disorder at the optic ganglion, with which the glaucoma can be detected at a much earlier stage. Therefore the macular threshold examination of the suspicious can facilitate an early diagnostic rate of glaucoma.
