Ocular disability--WHO grade 2 in persons affected with leprosy.

Leprosy remains to be a leading cause of peripheral neuropathy and disability. In recent years under Leprosy control programme more stress is being laid on disability assessment. This study was aimed to find prevalence of grade of Ocular disability among persons affected with leprosy (PAL) according to WHO disability grading scale and to find Ocular contributors to grade 2 disability in PAL. A cross sectional study was carried out in tertiary care hospital in Lucknow, Uttar Pradesh. About 302 PAL were interviewed and their eyes clinically examined during 2 years. Data was analysed in percentages, x2 test, Anova. Ocular disability was found in 39.40% persons affected with leprosy (PAL). Of 604 eyes, 13.07% had grade 1 disability and 19.86% had grade 2 disabilities. Bilateral disability was more common than unilateral disability. Ocular disability was more common in PAL with more than one year of leprosy and even higher in those staying in leprasoria (p = 0.012). The most common cause of ocular grade 2 disabilities was corneal involvement (14.23% PAL). Cataract was found to be the most common cause of visual disability (although it is not caused by leprosy). Screening for ocular disability should be incorporated as a routine protocol in PAL to reduce the severity of Ocular disability. Early diagnosis and prompt preventive measure is essential to reduce the burden of visual impairment and blindness in PALthus bringing down the load of grade 2 disability due to leprosy in the society which in itself is an indicator of leprosy control.

Retinal profile: a clinical indicator of severity in dengue fever in a suburban Indian environment.

PURPOSE: To study the retinal changes in subjects suffering from dengue fever and check if these changes can be taken as sufficient indicator of severity and progression of the disease. PATIENTS/METHODS: A detailed history was recorded of 118 patients on whom ocular examination, including direct ophthalmoscopy, indirect ophthalmoscopy and coloured fundus photography, was performed. RESULTS: Forty-seven percent of patients were found to have posterior segment abnormalities. Retinal vein dilatation or tortuosity was the most common finding followed by changes in the optic disc (8.4% of patients) and background haemorrhage (6.7% of patients). With increasing severity of thrombocytopenia, the proportion of patients with retinal abnormalities increased. In patients with grade I thrombocytopenia, no fundal abnormality was found. In those with grade II thrombocytopenia, fundal abnormality was found in 13.63% patients, whereas in the grade III category it was 27.90%. CONCLUSIONS: Severity of thrombocytopenia had a significant association with retinal abnormalities. Occurrence of fundus changes increases with an increase in severity of thrombocytopenia. Fundus changes were found in all patients with grade IV thrombocytopenia.
