To investigate the performance of the simultaneous interocular brightness sense test in patients with ocular hypertension and primary open angle glaucoma (POAG).
Brightness matches were obtained for an age-matched control sample and for patients with ocular hypertension and POAG. In addition, for the patients with POAG, visual field defects were quantified and a risk factor count was established for those with ocular hypertension.
Nineteen patients with ocular hypertension, 20 patients with POAG, and 61 age-matched controls participated in the study.
Seven patients with ocular hypertension exhibited brightness perception asymmetry outside normal limits for age-matched controls. Of these, six were at high risk of having glaucoma develop and only one of the remaining 12 was found to be at similar risk. All 20 patients with established POAG had results outside the normal limits for a test sensitivity of 100%. Three control observers had abnormal results, giving a test specificity of 95%.
The simultaneous interocular brightness sense test is quick and simple to perform and is suitable for a wide age range of patients. It warrants further assessment as a means of screening for ocular hypertension and glaucoma.
研究双眼同时亮度感觉测试在高眼压症患者和原发性开角型青光眼（POAG）患者中的表现。
获取年龄匹配的对照样本以及高眼压症患者和POAG患者的亮度匹配结果。此外，对于POAG患者，对视野缺损进行量化，并为高眼压症患者建立危险因素计数。
19例高眼压症患者、20例POAG患者和61例年龄匹配的对照者参与了该研究。
7例高眼压症患者表现出超出年龄匹配对照正常范围的亮度感知不对称。其中，6例有患青光眼的高风险，其余12例中仅1例被发现有类似风险。所有20例确诊的POAG患者的测试结果均超出正常范围，测试灵敏度为100%。3名对照观察者结果异常，测试特异性为95%。
双眼同时亮度感觉测试操作快速简便，适用于广泛年龄范围的患者。作为一种筛查高眼压症和青光眼的方法，它值得进一步评估。
