STUDY OF ROLE OF B-SCAN ULTRASOUND IN OCULAR PATHOLOGY

Background: B-scan ultrasonography (Brightness modulation scan) is a pivotal two-dimensional imaging modality for assessing abnormalities in the posterior segment of the eye, especially when direct or indirect ophthalmoscopy is hindered by opaque media. This study aims to evaluate the role of B-scan ultrasound in diagnosing various ocular conditions and its utility in treatment planning and follow-up. A cross- Materials and Methods: sectional study was conducted in the Radiology Department from June 2023 to December 2023, after obtaining Institutional Ethics Committee approval. A total of 110 patients, meeting the inclusion and exclusion criteria, were enrolled. All ultrasonography procedures were performed using a standard machine equipped with a 7.5–10 MHz high-frequency probe by an experienced radiologist. The majority of patients (55.45%) were aged between 40 and 60 years, wit Results: h a higher prevalence in males. Among the patients with dense cataracts (n=85), B-scan ultrasound revealed normal ndings in 91.76% of cases, while 8.23% demonstrated posterior segment pathology. The most common intraocular pathology identied was vitreous hemorrhage (12.72%), followed by retinal detachment (4.54%) and vitreous degeneration & asteroid hyalosis (3.63% each). The sensitivity and specicity of B-scan ultrasonography in detecting posterior segment pathology were 95.24% and 98.91%, respectively. B-scan ultrasonography is a valuable tool for evaluating the posterior segment Conclusion: in the presence of opaque ocular media and plays a critical role in preoperative planning. It is particularly benecial in cases of dense cataract and diabetic retinopathy, where it should be routinely employed to detect conditions like vitreous hemorrhage and asteroid hyalosis. B-scan ultrasonography should be the rst-line screening modality for posterior segment lesions.
