ARN is a fulminant disorder, which if treated early and aggressively gives good results.

Eales' disease is a bilateral recurrent retinal vasculitis disorder and timely treatment with steroid and/or laser photocoagulation result in better visual outcomes.

Purpose:To elucidate the clinical course of diabetic retinopathy (DR) after renal transplantation (RT) in a hospital based cohort.Design:Retrospective study.Materials and Methods:A total of 56 eyes of 28 patients, who had DR and end stage renal disease (ESRD) due to diabetes and had undergone RT, were included in this study. Diagnosis and management of DR was carried out according to early treatment of diabetic retinopathy study (ETDRS) guidelines. DR outcome was defined as worsening if there was >2 step increase in the grade of DR or need for intervention such as laser (macular or pan retinal) or vitreoretinal surgery, improvement for <2 step change while stabilization was defined if DR remained within these two limits.Results:The mean age of the patients were 48.9 years. The mean duration of diabetes in the study group was 12.7 years. The patients were followed-up for a mean period of 52.2 ± 43.6 months. The pre-transplant mean Best corrected visual acuity (BCVA) was 0.4876 log MAR units and post-transplant mean BCVA was 0.4858 (P = 0.05). However, there was a significant visual improvement in first 20 months of renal transplant (P = 0.03). Worsening of DR was noted in 16 (32%) eyes whereas improvement was seen in 4 (8%). However, majority of eyes 30 (60%) had stable retinopathy at the final follow-up.Conclusions:RT stabilized the retinopathy status in the majority of patients although in a minor subset the disease course was unpredictable.

Aim:To evaluate the efficacy of an automated retinal image grading system in diabetic retinopathy (DR) screening.Materials and Methods:Color fundus images of patients of a DR screening project were analyzed for the purpose of the study. For each eye two set of images were acquired, one centerd on the disk and the other centerd on the macula. All images were processed by automated DR screening software (Retmarker). The results were compared to ophthalmologist grading of the same set of photographs.Results:5780 images of 1445 patients were analyzed. Patients were screened into two categories DR or no DR. Image quality was high, medium and low in 71 (4.91%), 1117 (77.30%) and 257 (17.78%) patients respectively. Specificity and sensitivity for detecting DR in the high, medium and low group were (0.59, 0.91); (0.11, 0.95) and (0.93, 0.14).Conclusion:Automated retinal image screening system for DR had a high sensitivity in high and medium quality images. Automated DR grading software's hold promise in future screening programs.

High altitude retinopathy is a condition often seen among mountain climbers or among persons who reach high altitudes rapidly. In this report, we describe a case of a 57 year old healthy gentleman who presented with diminution of vision in both the eyes associated with retinal hemorrhages and the spontaneous resolution of the same.
