Abstract

The study's goal is to assess central corneal thickness in individuals with normal-tension glaucoma, primary open-angle glaucoma, and ocular hypertension. The current study aims to calculate the CCT in individuals with normal-tension glaucoma, primary open angle glaucoma, ocular hypertension, and healthy individuals. to research how glaucoma patients' central corneal thickness affects their diagnosis and care. Materials And Methods: This prospective observational study was collected from patients of normal tension Glaucoma, primary open-angle glaucoma, & ocular hypertension presenting to the Ophthalmology Department, Narayana Medical College and Hospital, Nellore from December 2021 to December 2022. This study was carried out after approval from the institute’s ethical committee and taking written consent from the patients. All the samples were collected and values documented. The sample size of the present study was 100 patients. Results: Patients with glaucoma were categorized using the corrected IOP for CCT. NTG patients were reclassified as POAG patients in 22.7% of cases, and OHT patients were reclassified as Normal in 25% of cases. According to this study, we concluded that OHT patients have significantly higher CCT than controls & POAG patients, while normal-tension glaucoma patients have significantly lower CCT than controls & POAG patients. Conclusion: This randomized comparative study led us to the conclusion that, while OHT patients' CCT was significantly higher than that of controls and POAG patients', normal-tension glaucoma patients' CCT was significantly lower. There is no statistically significant difference between patients with primary open angles and controls.
