This study aims to evaluate the utility of High-resolution Ultrasonography in the Evaluation of Posterior Segment Ocular lesions by using Sensitivity and Specificity.Materials and Methods:\u00a0A hospital-based retrospective study enrolled 81 patients in a tertiary care hospital. Clinical and ophthalmological examinations were performed followed by USG of the orbits. B-mode USG was done with a 7.5\u201313 MHz linear probe. The final diagnosis was made by correlating the USG findings with clinical and ophthalmological examinations.Statistical analysis:\u00a0Sensitivity, specificity, the positive predictive value, the negative predictive value, and the accuracy of B-scan USG were compared with the ophthalmological findings by using the Chi-square test.Results:\u00a0Of 81 patients (n=48 males and n=33 females) with a mean age of 38.98 \u00b1 16.48 [SD] years, posterior segment ocular lesions in association with cataracts were found in 27 (33.3%) patients, whereas 14 (51.9%) patients had posterior vitreous detachment (PVD), 10 (37%) patients had retinal detachment (RD), and 1 (3.7%) patient had choroidal detachment (CD). Posterior segment ocular pathologies were found in 17 (21%) patients with blunt ocular injuries, whereas 8 (47.1%) patients had PVD, 4 (23.5%) patients had RD and 4 (23.5%) patients had CD. The ocular USG had a sensitivity of 87.32%, specificity of 80%, and accuracy of 86.42% with a statistically significant difference between the USG findings and the Ophthalmology diagnosis of the posterior segment ocular abnormalities of a\u00a0p-value of 0.0005.Conclusion:\u00a0High-resolution ultrasound is one of the best and an easily available imaging modality for the evaluation of posterior segment ocular pathologies, especially in the presence of opaque ocular media.<\/jats:p>","DOI":"10.15388\/amed.2023.30.2.9","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T04:49:12Z","timestamp":1697604552000},"page":"177-186","source":"Crossref","is-referenced-by-count":2,"title":["Utility of High-Resolution Ultrasonography in the Evaluation of Posterior Segment Ocular Lesions Using Sensitivity and Specificity"],"prefix":"10.15388","volume":"30","author":[{"given":"Deb K.","family":"Boruah","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisy","family":"Vishwakarma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pallavi","family":"Gogoi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Navneet R","family":"Lal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arup","family":"Deuri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"6097","published-online":{"date-parts":[[2023,10,18]]},"reference":[{"key":"ref0","unstructured":"Byrne SF, Green RL.
