Abstract

AIM: To evaluate a possible correlation between central corneal thickness (CCT) and optic disc area in eyes with glaucoma.

METHODS: A cross sectional study of 90 eyes diagnosed to have glaucoma was done. Ocular evaluation with visual acuity testing, baseline IOP, gonioscopy; fundus ,pachymetry, HVF 24’2 and OCT-RNFL was done in all our patients. Correlation between CCT and optic disc area was done. Pearson’s correlation coefficient was calculated to assess the associations between CCT and optic disc area.

RESULTS: The mean CCT was found to be 492µm and mean optic disc area 2.2mm2. 43.6% of patients were male 53.4 %were female. Mean IOP was 17.67 . Pearson’s correlation coefficient was found to be -0.213 between CCT and optic disc area.

CONCLUSION: This study highlights the inverse correlation between CCT and optic disc area. Eyes with larger disc area and thinner cornea were more prone for glaucomatous progression compared to eyes with thicker cornea and smaller optic disc area.
