The latest estimates of the World Health Organization (WHO) indicate that there are 161 million visually impaired people worldwide, 37 million of which are blind, with a yearly increase of 1 to 2 million; it means approximately 0.85% of the world population. Another 135 million show visual impairment. This research was performed to determine the frequency of ocular diseases in ophthalmic patients of Urmia Imam Khomeini Hospital. This cross sectional and descriptive study was performed on 500 patients who referred to Imam Khomeini Hospital of Urmia. Samples were selected randomly. Data collected by using questioner and the results were analyzed using SPSS software. 146 (29.2%) right eye, 143 (28.6%) left eye, and 211 (42.2%) both eyes of patients affected by diseases. In this study ocular diseases frequencies were: cataract 104 (20.8%), refractive errors 96 cases (19.2%), conjunctivitis 50 cases (10%), e yelid disease 46 cases (9.2%), pterygium 28 cases (5.6%), glaucoma 13 cases (2.6%), c ornea d isease 12 cases (2.4%), Amblyopia 5 cases (1%), Dry Eye 4 cases(0.8%), Strabismus 2 cases (0.4%). This research was performed to determine the frequency of ocular diseases in low size samples to be incomparable with other researches that were performed to determine the prevalence of ocular diseases in high size samples. We suggest more studies be performed to determine the prevalence of ocular diseases in high size samples.
