The oculo-kinetic perimetry glaucoma screening test (OKPGST) simplifies testing for glaucoma. Despite its acceptable degree of efficiency and practicability, its usage in sub-Saharan African appears limited.
To evaluate and compare the oculo-kinetic perimetry glaucoma screening chart against automated perimetry and clinical criteria in screening for glaucoma in a sub-Sahara African setting.
In the first stage, the test was conducted on selected eyes with reproducible glaucomatous visual field detects on perimetry with the KOWA AP125 central visual field plotter, and also in their age-matched controls. During the second stage at the rural outreach health posts, patients with clinically diagnosed primary open angle glaucoma (intraocular pressure of > 21mmHg and a cup/disc ratio > 0.5), and their age-matched controls were also screened with the test.
The test was positive in 107 of the 113 eyes with glaucomatous field loss on automated perimetry; and inaccurate in 2 of the 98 control eyes, giving a sensitivity of 94.7%, specificity of 98%, and an efficiency of 96.2%. Among patients with clinically diagnosed glaucoma at the rural health posts, the test was positive in 61 of 65 eyes, while it was inaccurate in 2 of 62 eyes of control patients, giving a sensitivity of 93.8%, specificity 96.8%, and an efficacy of 99.2%.
The oculo-kinetic perimetry glaucoma screening test with the KOWA performed well, using the KOWA automated perimeter as a standard. It is a convenient, rapid, reliable and inexpensive screening tool in diagnosing primary open angle glaucoma in rural health establishments where conventional perimeters are lacking.
眼动视野计青光眼筛查试验（OKPGST）简化了青光眼检测。尽管其具有可接受的效率和实用性，但在撒哈拉以南非洲地区的应用似乎有限。
在撒哈拉以南非洲地区，评估并比较眼动视野计青光眼筛查图表与自动视野计及临床标准在青光眼筛查中的效果。
第一阶段，对使用KOWA AP125中心视野绘图仪进行视野检查时可重复性检测到青光眼性视野缺损的选定眼睛及其年龄匹配的对照进行该试验。第二阶段，在农村外展卫生站，对临床诊断为原发性开角型青光眼（眼压>21mmHg且杯盘比>0.5）的患者及其年龄匹配的对照也进行该试验筛查。
在113只经自动视野计检测有青光眼性视野缺损的眼睛中，该试验107只呈阳性；在98只对照眼中，2只结果不准确，灵敏度为94.7%，特异性为98%，有效率为96.2%。在农村卫生站临床诊断为青光眼的患者中，65只眼中61只试验呈阳性，而在62只对照患者眼中，2只结果不准确，灵敏度为93.8%，特异性为96.8%，有效率为99.2%。
以KOWA自动视野计为标准，使用KOWA进行的眼动视野计青光眼筛查试验表现良好。在缺乏传统视野计的农村医疗机构中，它是一种方便、快速、可靠且廉价的原发性开角型青光眼诊断筛查工具。
