Abstract
: Posterior segment evaluation is essential in diagnosing sight-threatening ocular pathologies. However, media opacities such as dense cataracts, corneal opacities, and vitreous hemorrhage often preclude direct visualization. B-scan ultrasonography (Brightness-mode scan) is a valuable imaging tool in such cases, providing real-time, non-invasive cross-sectional images of intraocular structures.This study aimed to evaluate the role of B-scan ultrasonography in diagnosing posterior segment pathologies in patients with opaque ocular media and to correlate ultrasonographic findings with clinical diagnoses.
Materials and Methods: A prospective observational study was conducted on 140 eyes from 100 patients with opaque media at Index Medical College Hospital & Research Centre, Indore, over 12 months. All patients underwent detailed clinical examination followed by B-scan ultrasonography using a 10 MHz probe. Findings were documented and analyzed to determine the prevalence and pattern of posterior segment pathologies.
Results: Of the 140 eyes examined, 63 eyes (45%) showed posterior segment abnormalities. Vitreous disorders were most common (60%), followed by retinal detachment (14.2%) and combined retinal detachment with vitreous hemorrhage (11.6%). B-scan findings supplemented the clinical diagnosis in 70% of eyes and correlated in 27%. In 3% of eyes, B-scan failed to detect optic nerve pathologies due to dense hemorrhage. Lenticular opacity was the most frequent cause of media opacity (68%).
