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.
Keywords: Primary open angle glaucoma, Primary angle closure glaucoma, Central corneal thickness, RNFL thickness.
