PREDICTIVE AND DIAGNOSTIC SCREENING TEST FOR GLAUCOMA

这项研究的目标是记录和描述 伴有青光眼的视网膜神经纤维层的出现 视野损失；并确定这样的可靠性和价值 变化，单独和结合各种光盘的外观 参数，作为识别已经具有视觉的个体的一种手段 视野损失，并预测哪些眼部高血压患者最终将 发展场损。正常对照组、眼部高血压患者和患者 随着青光眼视野丧失的确立，将前瞻性地进行追踪， 反复检查，并拍摄他们的椎间盘和神经纤维层。 这些照片将以蒙面、随机、受控的方式阅读 以及测试的敏感性和特异性，在时间关系中 最终导致青光眼视野丧失，已确定。

The objectives of this study are to document and describe alterations in the appearance of the retinal nerve fiber layer that accompany glaucomatous visual field loss; and to determine the reliability and value of such changes, alone and in combination with the appearance of a variety of disc parameters, as a means of identifying individuals already having visual field loss, and predicting which ocular hypertensives will eventually develop field loss. Normal controls, ocular hypertensives, and patients with established glaucomatous field loss will be followed prospectively, repeatedly examined, and their disc and nerve fiber layer photographed. These photographs will be read in masked, randomized, controlled fashion and the sensitivity and specificity of the test, in temporal relationship to the eventual onset of glaucomatous field loss, determined.
