Patients with glaucoma had slightly thinner corneas compared with healthy controls, according to a study. The difference was weakly significant when left eyes were compared.
The case-control study in Ghana analyzed 253 patients with primary open-angle glaucoma and 253 subjects without glaucoma who were matched for age and gender.
Central corneal thickness (CCT) was measured with ultrasonic pachymetry.
Mean CCT of the right eye was 524.28 µm in glaucomatous patients and 530 µm in controls. The difference was not significant. Mean CCT of the left eye was 524.7 µm in glaucomatous patients and 531.06 µm in controls (P = .05).
No correlation was observed between cup-to-disc ratio and CCT as an indicator of severity of glaucoma.
