Background: Blindness causes human suffering is economically devastating, and many early deaths. In India cataract has been reported to be responsible for 50-80% of the bilaterally blind in the country. B-Scan ultrasonography is a non-invasive, efficient, reliable and inexpensive diagnostic technique for evaluation of ocular pathology. Hence; the present study was undertaken for accessing the incidence of intraocular pathologies detected by B-Scan ultrasound examination in patients having dense cataracts. Materials & methods: A total of 50 patients diagnosed with dense cataract posted for cataract extraction surgery were included. Complete demographic and clinical data of all the patients was obtained. Before performing ultrasonographic examination, informed consent was obtained from the patients. B scan was carried out in all the patients. Afterwards, all the patients underwent cataract surgery. Postoperative fundus findings were evaluated and sensitivity of B scan was assessed. The data analysis was done by calculating frequency and percentage of different outcomes and were tabulated and analysed by using SPSS software. Results: Normal B Scan findings were seen in 62 percent of the patients. Posterior vitreous detachment was seen in 12 percent of the patients. Vitreous degeneration was seen in 14 percent of the patients. Superior retinal detachment and sub hyaloid haemorrhage was seen in 2 percent of the patients each. Vitreous degeneration was seen in 14 percent of the patients. Overall sensitivity and specificity of B Scan was 100 % and 90.48% respectively. Conclusion: B Scan is immensely helpful in diagnosis and proper evaluation of patients and for planning a surgery. Key words: B Scan, Ultrasound, Cataract
