Abstract: The present study aimed to study the effectiveness of B scan in assessing the posterior segment in patients with ocular trauma, so that further treatment plan can be decided and prognosis can be improved. The study was conducted as a cross-sectional study at tertiary care centre during the study period of 1 year on 42 patients presenting with history of ocular trauma. Patients were subjected to detailed history and ocular examination followed by B scan ultrasonography for ruling out posterior segment pathology. Mean age of 42.7±20.2 years and 45.2% patients belonged to 41 to 60 years of age. About 54.8% cases were females. About 50% cases had one or the other posterior segment finding. Retinal detachment followed by vitreous hemorrhage were the most common findings, observed in 19% and 11.9% cases respectively. Avulsion of optic nerve was the least common finding (2.4%). B scan ultrasonography plays an important role in management of patients with ocular trauma for the detection of hidden posterior segment lesions. B scan must be performed routinely in all the cases of ocular trauma for early diagnosis and appropriate management of each case and to reduce the ocular morbidities.
