ABSTRACT
Retinal detachment denotes separation of the sensory retina from the underlying retinal pigment epithelium. The most common type of retinal determent is the rhegmatogenous retinal detachment. Scleral buckling is the most well-known and effective surgical technique. To evaluate the characteristics of patients with rhegmatogenous retinal detachment, predisposing factors and surgical results of scleral buckling at eye center of Qazvin University of Medical Sciences. This was a descriptive analytical study carried out on existing data of 118 patients with clinical diagnosis of rhegmatogenous retinal detachment with minimum follow up of 3 months in 2004. All patients were examined using SLM and indirect ophthalmoscopy. Data on demographic characteristics and surgical outcomes were collected and further analyzed, statistically. Success in scleral buckling procedure was defined as attachment of retina by a single procedure and failure in cases with need for more than one course of action. A total of 118 eyes from 118 patients [76 males and 42 females] aged 12-81 with a mean age of 53.75+ 17.4 were studied. The mean follow up duration was 11.5 months. Success rate of operation in patients with PVR A and B was 96% and with PVR A.B. and C1 pre-operation 92.2%. Extent of detachment, longer duration of retinal detachment, aging, and PVR c1 were shown to have adverse effects on results of surgery. Scleral buckling is an appropriate surgical procedure to correct rhegmatogenous retinal detachment however, many factors such as extent of retinal detachment PVR c1, aging, and longer duration of retinal detachment influence the success rate of operation

Diabetes mellitus has several ophthalmic complications among those the retinal complication is considered to be the main cause of poor sight or loss of vision. To evaluate and determine the prevalence of diabetic retinopathy and also the factors influencing the progression of disease.This cross sectional study was conducted at Bouali medical center [Qazvin] in a period between the years 2000-2001 in which 188 eyes from 94 patients with type one and type two diabetes were selected for the study. The patients underwent complete eye examination including indirect, three mirrors contact lens and +90 funduscopy lens. The results of examinations and the risk factors were recorded in an information form. The data were analyzed using t-test, X[2] and odd's ratio. Among the patients [57 females and 37 males] 24 had type 1 [juvenile type] and 70 had type 2 diabetes [adult type]. Nineteen male patients [51.4%] and 30 female patients [52.6%] had diabetic retinopathy [OR= 0.95]. The mean age of the cases with retinopathy was 62.08 +/- 14.17 years and for those without retinopathy 47.31 +/- 12.9 years. The mean duration of diabetes with retinopathy was 109.27 months whereas in those without retinopathy it was 53. 96 months [P=0.0001]. The mean preprandial blood glucose concentrations in the first and second groups were 280.43 and 156.84 mg/dl, respectively. Retinopathy change was found in 49 patients [51.1%] in whom 65.3% showed non proliferative diabetic retinopathy [NPDR] and 34.7% with a proliferative diabetic retinopathy [PDR]. Prolong Diabetes, age and hyperglycemia are the main causes of retinopathy. So the cooperation of internist in referring diabetic patients to ophthalmologists is recommended
