ASSESSMENT OF CORRELATION BETWEEN INTRA OCULAR PRESSURE AND MYOPIA AT TERTIARY CARE HOSPITAL

Objective: To detect correlation between intra ocular pressure and myopia at tertiary care hospital. Material and methods: This cross sectional study was conducted at Department of Ophthalmology, Bahawal Victoria Hospital, Bahawalpur from March 2018 to September 2018 over the period of 6 months. Total 500 patients with myopia having age 7-35 years either male or female attending ophthalmology outpatient department were included in this study and correlation between intra ocular pressure and degree of myopia was assessed. Results: Total 500 patients with myopia were selected for this study. Out of 500 myopic patients, 224 (44.8%) patients were male and 276 (55.2%) patients were female. Total 21 (4.2%) patients belonged to age group 7-10 years followed by 47 (9.4%) patients to age group 11-15 years, 143 (28.6%) patients to age group 16-20 years, 137 (27.4%) patients to age group 21-25 years, 122 (24.4%) patients to age group to 26-30 years and 30 (6%) patients to age group 31-35 years. Mean intra ocular pressure was 15mmhg, mean radius of corneal curvature was 44.12D, mean anterior chamber depth was 3.55mm, mean lens thickness was 3.56mm. Conclusion: Results of present study showed that most of the patients with myopia were between 16-20 years. Females were more victim of myopia as compared to males. Correlation between degree of myopia and intra ocular pressure was not detected. But anterior chamber depth, lens thickness, vitreous chamber depth and axial length were statistically very significant with amount of myopia. Keywords: Myopia, IOP, corneal curvature, glaucom
