Background: Present study investigated the occurrence of cataract in dogs presented to the Teaching Veterinary Clinical Complex (TVCC) and Department of Veterinary Surgery and Radiology under Odisha University of Agriculture and Technology, Bhubaneswar during a period of four months. During the study period, a total number of 3847 canine cases were registered at TVCC, out of which 23 cases registered under the RKVY project for different types of ophthalmic affections. There were only eight canine cataract cases with overall prevalence of 0.2% among total canines presented to TVCC and 34.78% of total canines presented with some sorts of ophthalmic affections. Methods: Menace reflex, pupillary light reflex, maze test, obstacle test, catoptrics test, Schirmer’s tear test (STT), Schiotz tonometry, Slit lamp bio microscopy and fundus examination -using indirect ophthalmoscope (IO) and fundus camera, were carried out in all the cases studied. Result: Occurrence of cataract was higher in Spitz (50%). Males had more incidences (62.5%) of cataract. The ages of the dogs were less than 10 years. B mode ultra-sonographic (USG) examination revealed increased echogenecity of lens in all cataract affected dogs while corneal opacification was found in two cases. Cataract was extracted by phaco-emulsification in three dogs and by small incision cataract surgery (SICS) technique in one dog.

Background: In malaria endemic areas diagnosis of severe malaria by microscopy and immunodiagnostic test is confounded by asymptomatic peripheral blood parasitemia. In such settings, retinal changes by ophthalmoscopy showed some diagnostic utility. Contribution of ophthalmoscopy in diagnosis of severe malaria in children is not well studied in Bangladesh. The aim of this study was to describe the retinal findings in children of cerebral and non-cerebral severe malaria by direct and indirect ophthalmoscope and relate their outcome and to determine the course of changes in the fundus. Methodology: In this prospective observational study 130 consecutive children aged between 6 months to 12 years admitted with confirmed severe Plasmodium falciparum malaria in pediatrics ward of Chittagong Medical College Hospital, Chittagong, Bangladesh were assessed by both direct and indirect ophthalmoscopy during the period of April 2008 to March 2009. Results: Out of 130 patients 80 children had cerebral malaria and of these 49 (61.2%) had some degree of retinopathy; 24 (48%) of 50 with non cerebral severe malaria had retinopathy. Predominant retinal changes were Retinal hemorrhage and Macular whitening each in 53 (40.77%) patients, followed by peripheral whitening, Vessels changes and papilloedema in 50 (38.46%), 40 (30.77%) and 14 (10.78%) patients respectively. With indirect ophthalmoscope as reference, direct ophthalmoscopy had a high sensitivity to detect macular whitening, and papilloedema but was less sensitive to detect peripheral whitening and vessel changes. Patients with retinopathy had more chance to had unfavorable outcome (Death) in comparison to the patients who had not {Odds ratio:1.09 (95% CI:1.017-1.167)}. Most of these retinal changes were transient and resolved gradually as clinical condition improved. Conclusion:Features compatible with malarial retinopathy were commonly found in our children with severe malaria. Ophthalmoscopy is an important clinical tool to aid in diagnosis and prognosis in children. However, indirect ophthalmoscopy provides better information than direct ophthalmoscopy.
