CORRELATION OF PERIPHERAL DISPLACEMENT THRESHOLDS AND OPTIC DISC PARAMETERS IN OCULAR HYPERTENSION

Both peripheral displacement thresholds and measurement of optic disc parameters have been advocated in the early diagnosis of glaucoma at t he stage before scotomata are detected on conventional visual field as sessment. The peripheral movement displacement thresholds were measure d in 50 eyes of 50 patients with ocular hypertension and a significant correlation was found with neuroretinal rim areas measured using a co mputerised image system. There was also a significant correlation with optic disc diameter but no correlation with cup-disc ratio. The resul ts support the proposition that measurement of peripheral movement dis placement thresholds may be a useful tool in the detection of early gl aucomatous optic nerve damage.
