목적 : To examine the effects of artificial tear administration on perimetry of primary open-angle glaucoma patients with dry eye.
방법 : A total of 48 patients with primary open-angle glaucoma experienced in automated perimetry with symptoms of dry eye were enrolled in this study. After their pretest visit, they were instructed to use artificial tear four times a day in both eyes for 1 week. After 1 week, patients had visual field testing. Test taking time, reliability parameters (false-positive and false-negative errors) visual field indices and number of depressed points at different probability levels (P<5%, P<2%, P<1%, P<0.5%) in both total and pattern deviation plots were compared using paired T-test.
결과 : We found significant improvement in reliability parameters (false-positive errors from 2.3±2.2 to 2.0±1.9, P=0.02; and false-negative errors from 7.4±6.4 to 4.7±3.6, P=0.01) and visual field indices (MD increased from 5.96±5.61 to 4.58±4.53, P=0.001; PSD from 4.66±2.95 to 4.14±2.77, P=0.04) in the second testing after artificial tear administration. The number of depressed points at probability levels P<1% (P=0.03) and P<0.5% (P=0.04) at total deviation plot and P<2% (P=0.02) and P<0.5% (P=0.009) in pattern deviation plot decreased significantly.
결론 : Artificial tear administration in glaucomatous patients with dry eye seems to improve significantly reliability parameters and visual field indices.
