Abstract

Aims and Objectives: To assess the diagnostic value of B - Scan ultrasonography in evaluation of posterior segment disorders of eye and correlate the results with clinical diagnosis.
Material and Methods: A descriptive cross-sectional study of ultrasound B-scan was performed on 170 eligible eyes of 136 patients.
Results: Maximum 72 (52.94%) cases belong to 51-70 age group. 86/136 (63.24%) were males and 50/136 (36.77%) were females. 148 (87.05%) cases presented with opaque media and 22(12.94%) with clear media. 52 (30.59%) patients had a history of trauma and 34 (25%) subjects presented for issue of blindness certificate. Most common final diagnosis was retinal detachment in 42 (24.70%) eyes, posterior vitreous detachment in 35 (20.6%) eyes, vitreous haemorrhage in 32 (18.82%) eyes, globe tear in 8 (4.70%) eyes, dislocated lens in vitreous in 8 (4.70%) eyes, asteroid hyalosis in 8 (4.70%) eyes, phthisis bulbi in 7 (4.11%) eyes, dislocated PCIOL in 6 (3.52%), endophthalmitis in 5 (2.94%) eyes, s/p scleral buckling in 5 (2.94%), retinoblastoma in 4 (2.35%) eyes, persistent hyperplastic primary vitreous in 3 (1.76%) eyes, retinochoroidal coloboma in 2 (1.17%) eyes, silicon oil vitreous in 2 (1.17%) eyes, and 1 (0.58%) eye each with metallic intraocular foreign body with endophthalmitis with occult scleral perforation, choroidal detachment and optic disc drusen.
Conclusions: Ultrasound confirmed the provisional diagnosis in 50 eyes (29.41%) and supplemented or subclassified the diagnosis in 119 eyes (70%). Depending upon the clinical findings and B-scan these patients were either intervened surgically or a more complete diagnosis could be documented after B-scan.
