Central corneal thickness in patients with normal-tension glaucoma
Konareva-Kostianeva MI; Atanassov MAFolia Medica 2007; 49: 36-41
PURPOSE: To compare the central corneal thickness of eyes with proved normal-tension glaucoma with that of eyes without glaucoma. DESIGN: A prospective study. METHODS: The study included 30 consecutive patients with normal-tension glaucoma (60 eyes, group I), and 30 age- and gender-matched non-glaucoma patients (60 eyes, group II). Central corneal thickness was measured using an ultrasonic pachymeter (Pach IV, Accutome). The mean central corneal thickness of normal-tension glaucoma patients and controls were compared using independent samples t-test. RESULTS: The mean (± SD) central corneal thickness of normal-tension glaucoma and non-glaucoma patients was 517.4 ± 19.2 μm and 549.0 ± 39.4 μm , respectively. There was a significant difference in this parameter between the groups (P < 0.001). The mean intraocular pressure was higher in glaucomatous eyes (17.1 ± 2.3 vs. 16.3 ± 1.4 mmHg, P = 0.028). The visual acuity in normal-tension glaucoma eyes was lower than that in controls, but the difference failed to reach statistical significance (P = 0.069). CONCLUSIONS: The results indicate that corneas of patients with normal-tension glaucoma are thinner than those of non-glaucoma patients.
