Evaluation of various factors relating to intraocular pressure and CID ratio in patients referring to Shahid Mohammadi Hospital

Introduction: Intraocular pressure (10P) is determined by three factors: the rate of aqueous humor production by the ciliaryʹs body, the resistances to aqueous out flow across the trabecular meshwork and the level of episcleral vessel pressure. 10P varies with a number of factors, including: age, sex, race, systemic disease and diurnal variation. The purpose of this study is measurement of IOP and CID ratio in normal population. Methods: 200 persons who accompanied the patients referring to Shahid Mohammadi clinic underwent total eye examination, measure of IOP and CID ratio. The obtained data was then subject to Chi-Square test and Pearson Correlation Coefficient analysis (p <0.05). Results: In statistical result, 10P> 14 in the left eyes of persons with history of familial glaucoma was more than persons without familial glaucoma (p <0.01). the same result was attained for the right eyes. Also CID ratio was higher in persons with glaucoma familial history (p< 0.01). There was a positive correlation between age and right eye IOP (r=0.37) and left eye IOP (r=0.41) also there was a positive correlation between age and CID ratio. Conclusion: Age has an important effect on increasing IOP and CID ratio in both eyes, no difference between myopic and non myopic persons in IOP & CID ratio, and there is not any effect of myopic on IOP and CID ratio. The study suggested familial history of glaucoma has an important effect on increasing LOP and CID ration in both eyes.
