Abstract

Objective : To study the details of posterior segment lesions by A-B scan ultrasonography (USG) in presence of opaque media. Methods: 623 eyes of 500 outdoor and indoor ophthalmic patients having opaque media were subjected to A-B vector scan USG to evaluate underlying posterior segment disorders. 16 eyes had corneal opacities, 1 hypopyon, 3 hyphaema, 7 pupillary membranes, 14 vitreous opacities and 582 had lenticular opacities. Results: on A-B scan USG, 7 eyes had vitreous hemorrhage, 2 asteroid hyalosis, 13 vitreous membranes, 9 posterior vitreous detachment, 11 retinal detachment with PVR, 2 choroidal detachment, 1 choroidal rupture, 3 sub retinal hemorrhages,1 endophthalmitis, 4 IOFB’s, 1 phthisis bulbi, 1 retinoblastorma, 1 malignant melanoma, 1 nucleus drop, 3 IOL’s drop, While 563 eyes were found normal. Conclusion: Vector A-B scan is a valuable tool in evaluating posterior segment disorders in ascertaining prognosis as well as dictates effective and proper norms of management.
