Comparison of Visual Acuity, Refractive Status, Intraocular Pressure, Central Corneal Thickness, RNFL Thickness and Disc Changes Between Patients with Primary Open Angle Glaucoma and Primary Angle Closure Glaucoma - A Retrospective Observational Study

Abstract

Aim and objective: To compare visual acuity, refractive status, intraocular pressure, central corneal thickness, RNFL thickness and disc changes between patients with primary open angle glaucoma and primary angle closure glaucoma Materials and methods: A retrospective study conducted over a period of 6 months with a sample size of 172 eyes from 100 patients. Various parameters including Pachymetry, IOP and gonioscopy were performed. Result: POAG is more in prevalence in the age group of 45- 60 and more in males than females. In general, POAG groups were predominantly myopic and have a thinner central corneal thickness average 534±24.6µm and leading to effects in Intraocular pressure. PACG is more prevalent among males than females in contrary to our reference and it is common in the age group 40-60yrs. PACG’s were more predominantly Hyperopic and having thicker CCT on an average of 544±25.7 µm. Conclusion: This study concludes that more rapid glaucomatous changes is seen in the patients with POAG than PACG. These patients should be screened carefully and provided more diagnostic and preventive management.
