Abstract

Purpose : Macular hole is known to cause deterioration of vision, metamorphopsia, and a decline in fixation stability and binocular function. Using “IMO”, a head-mounted perimeter, (CREWT medical systems, inc., Tokyo, Japan) binocular random concurrent visual field analysis of unilateral macular hole patients was conducted in order to investigate credibility factors and functional parameters.

Methods : Fifteen patients with unilateral macular hole but without other ocular diseases causing macular visual sensitivity were included. Binocular visual field analysis was performed with both eyes open. The visual field of each eye was measured separately but concurrently. Fixation loss rate (FL), false-positive rate (FP) and false-negative rate (FN) as credibility factors, and foveal threshold (FT), macular sensitivity (MS), mean deviation (MD) and pattern standard deviation (PSD) as functional parameters of perimetry were examined.

Results : The median FL, FP and FN were 20.5%, 1.94%, 5.14% in affected eyes and 11.5%, 1.16%, 3.64% in fellow eyes respectively. There were no significant statistical differences between the rates in affected and fellow eyes (Wilcoxon rank-sum test, p=0.407, 0.447, 0.584, respectively). The number of cases of eyes with more than 20% fixation loss were 5 in affected eyes only, 1 in the fellow eye only, and 1 in both affected and fellow eyes. The median FT, MS, MD and PSD were, respectively, 28.6dB, -2.26dB, 2.22dB in affected eyes and 29.9dB, -0.937dB, 1.51dB in fellow eyes. FT, MS and MD were significantly lower in affected eyes (Wilcoxon rank-sum test, p=, 0.00407, 0.0256, 0.0287) and PSD was statistically higher in affected eyes (Wilcoxon rank-sum test, p=0.0256).

Conclusions : In binocular random perimetry, the eyes affected with macular hole were divided into low and high fixation loss rates. All of the functional parameters indicated decreased sensitivity in affected eyes. Binocular random visual field tests using IMO may elucidate the condition of eyes with unilateral macular disease under more natural circumstances.
