Thirty patients with ocular hypertension were tested for contrast sensitivity loss. Seventeen were not on treatment, and thirteen were receiving some form of pressure reducing therapy. The contrast sensitivity results of 63% of ocular hypertensive eyes were abnormal (greater than 2 SDs from the age matched norm). Thus it appears that contrast sensitivity can detect early visual loss in patients who have normal visual fields and it is suggested that this test might be used as a criterion for therapy in ocular hypertension. There was no significant difference in the intraocular pressures between patients who gave abnormal contrast sensitivity results and those who did not in the untreated group (p greater than 0.05), suggesting that intraocular pressure level is a poor predictor of optic nerve fibre damage in patients with ocular hypertension.
对30例高眼压症患者进行了对比敏感度损失测试。17例未接受治疗,13例正在接受某种形式的降压治疗。63% 的高眼压症患者的对比敏感度结果异常(比年龄匹配的正常范围高2个标准差以上)。因此,对比敏感度似乎可以检测出视野正常的患者早期视力损失,并且有人建议该测试可作为高眼压症治疗的一个标准。在未治疗组中,对比敏感度结果异常的患者与结果正常的患者之间眼压无显著差异(p大于0.05),这表明眼压水平不是高眼压症患者视神经纤维损伤的良好预测指标。
