History and Objectives: Due to the importance of recognition of the site of retinal tear in the treatment of retinal detachment, this study was performed on patients who had undergone surgical repair for retinal detachment in Fayz hospital of Isfahan during the year 1372.

Materials and Methods: The present research was performed by evaluation of the existing data and sex, age, the disease associated with retinal detachment, type and site of the tear, the status of the lens, history of previous cataract surgery and the associated systemic diseases in this group were evaluated from the patients’ records and statistically analyzed.

Results: In this study 126 eyes belonging to 123 patients, aged 47.7±21 years, were evaluated. The most common age for retinal detachment was 40-70 years. The most important diseases associated with retinal detachment were aphakia: 37 eyes (29%), eye trauma: 24 eyes (19%) and diabetes: 18 eyes (14%). The most common site of tear was supratemporal quadrant i.e. 38 eyes (30%) and horseshoe type retinal tear was the most common type of tear in this group of patients (82 eyes, 65%).

Conclusion: The frequency of site and type of tear was relatively similar with the previous studies, however, aphakia particularly following cataract surgery by the intracapsular and/or complicated extracapsular method is the most common cause of retinal detachment in our country.
