Retinopathy risk factors among diabetics in a tertiary care military hospital

To determine the frequency and risk factors for severity of retinopathy in diabetic patients referred to a tertiary military hospital. Cross-sectional study. Armed Forces Institute of Ophthalmology, Rawalpindi from Jun 2008 to Dec 2009. Diabetic patients aged 40 to 79, referred for suspected diabetic retinopathy [DR] on fundoscopy from medical outpatient clinic of Military Hospital Rawalpindi were randomly included in the study. Participants underwent a standardized interview and examination Retinopathy was assessed through dilated pupils, and graded into absent retinopathy, mild to moderate, or advanced. Presence of clinically significant macular edema [CSME] was also recorded. To evaluate the simultaneous effect of significant risk factors on the different stages of DR, multivariate regression analysis was carried out. Out of five hundred and ten patients, DR was confirmed in 63% cases with advanced retinopathy in 21.3%. In univariate analysis, duration of diabetes, fasting blood glucose, and presence of oedema were significantly associated with retinopathy [P<0.005] On multivariate analysis, however, only duration of diabetes [Odds Ratio 6.15 for 5 to 10 years and 38.29 for more than 10 years] and macular oedema [OR 6.617 95% CI 3.95-11.07] remained significant. CSME was present in 173 [33%] patients and its frequency increased with the severity of DR [P<0.001]. The frequency of DR among military personnel and their dependants was high with strong association to duration of diabetes. This underscores the importance of regular retinal detect DR in the early stages and timely intervention to prevent diabetes related blindness

Intralenticular foreign body with a clear lens

Intraocular foreign bodies [IOFBs] are not uncommon in patients of penetrating ocular trauma but intralenticular foreign bodies are rarely seen. Penetrating ocular injuries are observed more commonly in young men. Intralenticular foreign bodies cause visually significant cataract in almost all cases. We report here a case of a young soldier with intralenticular foreign body of about 1.5 mm in size sparing the visual axis and only causing focal cataractous changes. The foreign body remained innocuous for about 3 months of follow-up not causing any progressive cataract, glaucoma or uveitis. The foreign body was removed, lens aspiration was done and posterior chamber intraocular lens was implanted, as patient could not be followed on long-term basis. The vision was restored to normally within 2 months
