Evaluation of ultrasound B-scan in a tertiary eye care centre in Central India

: To evaluate the B-scan findings in tertiary eye care Retina Clinic in relevance to clinical management and to find out the visual potential in anterior segment pathology. We are tertiary eye care centre in Central India and do get referral from other centres as well as in house referral to Retina OPD. In present retrospective study, we evaluated 192 eyes of 181 patients, above 16yrs of age. All the B-scan were done by Quantel ABSOLU 15 MHz probe in supine position. A total of 192 patients were evaluated by B-scan. We have divided total 192 eyes in two groups 1 & 2, Cataract & Non-cataract groups respectively, for ease of understanding the indication of B-scan. Among total 192 eyes, 111 eyes (57.81%) were included in Group 1 & rest 81 eyes (42.18%) fall in Group 2. In group 1, the indications for B-scan were Mature Cataract. In group 2, the most common indication was Vitreous haemorrhage- 28Cases (34.56%), followed by post-surgical trauma- 17cases (20.98%), Corneal Opacity- 13 cases (16.04%), & Inflammatory- 10cases (12.34%). The remaining 13 cases (4 cases of Asteroid hyalosis, 3 cases of Disc coloboma, and 2 cases each of Optic Nerve Head Drusen, Microphthalmos & Intraocular foreign body) were grouped as miscellaneous -16.04%. B-scan is an important non-invasive and economical tool for posterior segment evaluation. We also noted very important observation that among 13 Corneal Opacity patients, 9 patients were having attached retina with normal sonic appearance of posterior segment which signifies the visual potential in these cases which are often overlooked.
