Purpose: The purpose of this study was to investigate the patients’ demographic characteristics, predisposing factors, clinical features, surgical interventions and intra-operative findings for patients with rhegmatogenous retinal detachment(RRD) who were hospitalized and operated at Kasr Al Aini hospital, over a time interval of 6 months. Patients and Methods: This is a prospective observational analytical epidemiological study that includedpatients with 1ry RRD who were admitted for surgical intervention at Kasr Al-Aini Teaching Hospital, CairoUniversity in a time period of 6 months starting from March 2013 to September 2013. The patients were selected from the outpatient Ophthalmology Clinic of Kasr Al-Aini Hospital. The primary outcome measures were the predisposing factors for the RRD (blunt trauma, myopia, previous cataract surgery, family history of RRD), and the clinical features of RRD (quadrants affected, macula on/off, number, types, location of breaks, presence and distribution of lattice, signs of posterior vitreous detachment(PVD) and presence and grading of proliferative vitreoretinopathy(PVR). The secondary outcome measures were the patients’ demographic data. Results: Sixty five (65 eyes) patients were included of which 19 eyes (29.2%) had total RRD.The patients' age ranged from 3 to 80 years of age with a mean value of 45.65± 18.56 years.The study included 40 males (61.5%) and 25 females (38.5%) with a female to male ratio of 1:1.6. Twenty-two eyes (33.8%) had high myopia (> -6 D), 15 eyes (23.1%) were aphakic/pseudophakic, and 13 eyes (20%) with a history of blunt trauma.The macula was attached only in 3 cases (4.6%).The size of the breaks ranged from 0.25 to 4 clock hours with a mean of 1.15±0.96,16 patients showed horse shoe tears, 16 patients showed holes, 3 patients showed giant tears, 4 patients showeddialysis , 2 patients showed slit shaped tears.In 24 (36.9%) patients in our study there was no breaks detected pre-operatively.Forty-four eyes (67.7%) had PVR-A, 11 eyes (16.9%) had PVR-B, and 10 eyes (15.4%) had PVR-C.Pars planavitrectomy (PPV) was done for 57 eyes (87.7%), of which 29 eyes had undergone phaco-vitrectomy (50.9%). Scleral buckling was done for 6 eyes (9.2%), and pneumatic retinopexy was done for 2 eyes (3.1%). Conclusion: This study showed that high myopia,peripheral retinal degenerations,pseudophakia/ aphakia, blunt ocular trauma and history of RD in the other eye, in a descending order were the main risk factors predisposing to RRD.
