All cases aged 3 months-90 years, the average age was (32.43±19.60) years, and the most common age group was 36-60 years. The ocular trauma occurred mostly in January with 71 cases (10.26%). On average, there were (57.67±6.33) patients per month. The main occupation of ocular trauma was farmer which included 210 cases (30.35%).
