A Study of Posterior Segment Evaluation by B-Scan in Hyper Mature Cataract

Purpose: To study the role of B-scans ultrasound in detection of posterior segment pathology in hyper mature cataract cases. Material and method: This study was conducted in Department of Ophthalmology, Chirayu Medical College and Hospital, Bhopal from October 2012 to October 2014.The study included 400 patients of dense cataract evaluated with high resolution 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 1.38:1 (M:F). Loss of vision and redness of eye were the leading symptoms. Posterior staphyloma was seen in 15 (3.52%) cases, Vitreous hemorrhage in 7 (1.64%), Vitreous membrane in 5 (1.20%), Chorioretinal Thickening in 6 (1.41%), and Retinal detachment 4 (0.94%) cases. Out of 400 patients 79 (19.6%) were having ocular and systemic risk factors like hypertension, diabetes, raised IOP, uveitis, myopia. Conclusion: From, the present study it was noted that B-scan is very efficient tool in diagnosing various ocular abnormalities. B-scan can categorize the lesions in the posterior chamber well, depending on the echotexture and anatomy. Preoperative posterior segment evaluation with ultrasound in patients with dense cataract can be used to detect pathologies that may influence the surgical strategy and the postoperative visual outcomes.
