Detection of Glaucomatous Visual Fields Using a Newly Developed Device with Retinal Projection Technology.

Abstract

We aimed to investigate the glaucoma-detecting ability of MEOCHECK, a novel and simple visual field measurement device based on retinal projection technology. This retrospective and observational study evaluated 94 glaucomatous eyes of 49 subjects and 31 non-glaucomatous eyes of 23 healthy subjects. We compared MEOCHECK's main output, Score 100, to visual acuity, intraocular pressure, optical coherence tomography-measured parameters (circumpapillary retinal nerve fiber layer thickness [cpRNFLT] and ganglion cell complex thickness [GCCT]), and automated perimetry-measured mean deviation (MD) in glaucomatous eyes. Score 100 showed significant correlations with age, visual acuity, cpRNFLT, GCCT, and MD (r = --0.38, p < 0.001; r = -0.42, p < 0.001; r = 0.65, p < 0.001; r = 0.59, p < 0.001; and r = 0.62, p < 0.001, respectively). Score 100 was statistically significantly lower in early- vs. moderate-stage glaucoma (p = 0.03) and in moderate- vs. severe-stage glaucoma (p = 0.002). A logistic regression analysis indicated that Score 100 could predict the presence of glaucoma, with an area under the receiver operating characteristic curve of 0.89. MEOCHECK, a novel device that uses retinal projection technology, effectively detected glaucomatous visual fields, demonstrating its potential as a reliable tool for glaucoma detection.
