Abstract

Introduction: Intraocular pressure (IOP) is determined by three factors: the rate
of aqueous humor production by the ciliary’s body, the resistances to aqueous out
flow across the trabecular meshwork and the level of episcleral vessel pressure.
IOP 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 C/D ratio in normal
population.
Methods: 200 persons who accompanied the patients referring to Shahid
Mohammadi clinic underwent total eye examination, measure of IOP and C/D
ratio. The obtained data was then subject to Chi-Square test and Pearson
Correlation Coefficient analysis (p<0.05).
Results: In statistical result, IOP>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 C/D 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 C/D
ratio.
Conclusion: Age has an important effect on increasing IOP and C/D ratio in both
eyes, no difference between myopic and non myopic persons in IOP & C/D ratio,
and there is not any effect of myopic on IOP and C/D ratio.
The study suggested familial history of glaucoma has an important effect on
increasing IOP and C/D ration in both eyes.
