Abstract

PURPOSE: To study the relationship between central corneal thickness (CCT) and parameters of glaucomatous damage

METHODOLOGY: Participants (n=114 eyes) were classified into three groups; 50 primary open angle glaucoma (POAG), 23 primary angle closure glaucoma (PACG) and 41 normal tension glaucoma (NTG) eyes. Central corneal thickness, intraocular pressure (IOP), cup to disc ratio (CDR), retinal nerve fibre layer (RNFL) thickness, visual field mean deviation (MD) and pattern standard deviation (PSD) were obtained.

RESULTS: CCT had a significant positive correlation with RNFL (p=0.013) thickness in POAG, with IOP (p=0.03) in NTG, with MD (p=0.011) in PACG while significant negative correlation with CDR (p=0.024) in POAG, and with CDR (0.006) and PSD (0.02) in PACG.

CONCLUSION: Eyes with thinner corneas tend to have more advanced glaucomatous damage and required aggressive management. Therefore, CCT should be considered as important factor in early diagnosis and management of glaucoma.
