Abstract: Purpose: Intraocular pressure changes have been, and still is, a topic of discussion. Increasing myopia has been constantly associated with increasing intraocular pressure. Myopia has long been identified as a risk factor for open angle glaucoma because of the changes in optic disc and pressure. Thus, repeated evaluation of all the factors that are related to changes in IOP levels is important. This can help to figure out the risk factors for open angle glaucoma in the form of variables that can be proved to be associated with IOP level changes. In this study, we will evaluate the intraocular pressure levels between moderate and high myopia, also taking age and gender in to account Methods: This is an Observational, hospital-based study conducted on 35 patients presented in the HAH centenary hospital in the period of 2 months at Delhi. Data confidentiality was maintained. The detailed demographic details along with ocular findings, systemic health findings, were collected for analysis. The test used for statistical analysis were Un-paired, 2- tailed, T-test, Two way ANOVA test. The software MS EXCEL was used. Results: The hospital-based study conducted at HAH centenary hospital evaluated 35 myopic patients (70 eyes) in the period of 2 months. Out of 35 patients, 20(57%) were moderate myopic (-3.00D to <-6.00D) and 15(42%) were highly myopic (-6.00D and more). Range of the age being 11- 55years. 20(57%) females and 15(42%) males were present in the sample. Only one patient had IOP level more than 21mmhg and was further examined for glaucoma tests which came out negative. All the evaluated patients had a C/D ratio less than 0.5 Conclusion: No significant association was found between IOP and myopia along with other factors such as age and gender. Small sample size and avoiding various others factors such as ocular biomechanics, corneal thickness, curvature etc. can be the reason for it. Overcoming these limitations can help confirming a conclusion and give results that would be different and convincing. The study needs further research time and evaluation.
