PURPOSE:To compare RNFL thickness in patients with ocular hypertension with that of controls. AIM: To study the role of SD-OCT in ocular hypertension. METHODS: 25 eyes of 15 patients with ocular hypertension and 25 eyes of 15 normal subjects seen in Regional Institute of Ophthalmology, Gandhi Medical College Bhopal were included in this prospective study conducted in the academic session of the year 2012 to 2013. Informed consent was obtained from all patients and controls. Ocular hypertensive eyes were defined as an IOP reading greater than 21 mmHg on at least two separate occasions, normal optic disc, visual fields and normal open angles. The control was selected from general OPD and staff of RIO. Control subjects were included if they had an IOP measurements less than 21 mmHg on at least two separate occasions, absence of glaucomatous optic nerve head, normal visual fields and no family history of glaucoma or other risk factors. Age and sex matched controls were included in the study. CONCLUSION: OCT can be useful adjuvant in ocular hypertensive patients for measurement of structural loss which precedes functional loss alerting ophthalmologist to start early treatment especially in presence of risk factor and contributes to quality of life. SD-OCT could determine significant differences between ocular hypertensive patients and healthy subjects in RNFL thickness measurement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
