Purpose: To study the role of B-scans ultrasound in detection of posterior segment pathology in cases of senile mature cataract. Material and method: This study was conducted in Department of Ophthalmology, Chirayu Medical College and Hospital, Bhopal from October 2012 to October 2017. The study included 1600 patients of mature cataract evaluated with B-Scan Ultrasonography for posterior segment lesions. Results: The cases were divided according to age ranging from 0-80 years. Male predominance was seen with sex ratio 1.37:1 (M:F). In this study Posterior staphyloma was seen in 62 (3.87%) cases, Vitreous hemorrhage in 28 (1.75%), Vitreous membrane in 30(1.87%), Chorioretinal Thickening in 25 (1.56%), and Retinal detachment 20 (1.12%) cases. Out of 1600 patients 320 (20.1%) were having ocular and systemic risk factors like hypertension, diabetes, increased IOP, uveitis. Conclusion: From, the present study it was noted that B-scan is very efficient tool in diagnosing various ocular abnormalities. Preoperative posterior segment evaluation with ultrasound in patients with hypermature cataract may influence the surgical results and postoperative visual prognosis.
