Comparison of the oculokinetic perimetry glaucoma screener with two types of visual field analyser.

We compared the accuracy and testing time of a new 26-point central visual field glaucoma screening device, the oculokinetic perimetry (OKP) screener, with the results obtained with the Friedmann field analyser standard program (phase 1) and the Humphrey field analyser 40-point screening program (phase 2). Seventy-three eyes of 73 subjects were tested in phase 1, and 142 eyes of 75 subjects in phase 2. The study population comprised patients with eyes that were ocularly normal and patients with eyes showing early cataract, posterior vitreous detachment, established chronic open-angle glaucoma or ocular hypertension. The OKP glaucoma screener demonstrated a sector concordance rate of 95% in phase 1 and 93% in phase 2. The OKP screener was three to four times more rapid in execution than the standard device. We feel that the OKP glaucoma screener is ideally suited for use by physicians in a family practice setting.
