Rhegmatogenous Retinal Detachment: Causes and Underlying Disorders

To evaluate the underlying causes of rhegmatogenous retinal detachment (RRD) in eyes operated for this reasion. Out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. Fifty-two percents of patients were less than 50 years old and 63.4% of them were male. Twenty-two percents of the eyes were aphakic or pseudophakic and 18% were myopic. Trauma was the cause of detachment in 10% of the eyes. More than one break was found in 70% of the eyes, 80% of which were less than 90 degree apart. Thirty percents of the eyes had only one break, 40% of which were in superotemporal and 30% in inferotemporal quadrant. Macular hole was found in 3.5%, dialysis in 6%, peripheral hole in 3.5%, and retinal tear in 81% of the eyes. In addition, PVR grade C or more was seen in 7.6% of the eyes. The causes, underlying disorders, and location of breaks is comparable with studies from other parts of the world. Evaluation of these parameters in other Iranian ophthalmic centers is suggested.
