Abstract
Purpose: To determine the incidence of primary open angle glaucoma in
patients presenting with Retinal vein occlusion in tertiary care hospital.
Study Design and Place of Study: Cross-sectional study.
Place and Duration of Study: Eye Unit II, Institute of Ophthalmology, King
Edward Medical University, Mayo Hospital, Lahore. from January 2016 to
December 2017.
Material and Methods: A sample size of 100 cases was calculated with 95%
confidence level, 5% margin of error. Non-probability consecutive sampling was
done. Adult patients of either gender presenting with retinal vein occlusion (RVO)
diagnosed within a month were included in the study. The demographic
information and Visual Acuity were recorded and a detailed slit lamp
examination, gonioscopy and fundoscopy was carried out. Applanation
tonometry for Intra ocular pressure (IOP) measurement was performed. Central
corneal thickness was measured and the correction factor was applied. If there
was raised Intraocular pressure (> 20 mm Hg), then patient was labeled as
glaucoma. Data was collected and analyzed by SPSS. Data was stratified. Post
stratification, Chi-square was applied.
Results: The mean age was 46.28 ± 15.02 years. On gender basis male were
found more involved as ratio was 1.6: 1. The Mean intraocular pressure was
15.87 ± 4.52 mm Hg. Primary open angle glaucoma was found in 14 (14%) of
patients.
Conclusion: Our Study concluded that the incidence of glaucoma is significant
in patients presenting with Retinal vein occlusion (RVO) in local population.
