Purpose: This study is done to evaluate the role of B-Scan in patients with corneal opacity, bullous keratopathy and anterior staphyloma. For knowing status of posterior segment in cases of traumatic hypheama, in case of dislocation of lens, in cases of occlusiopupillae, cataract and leukocoria via B Scan. For assessing cases of vitreous haemorrhagefor diagnosing retinal detachment and intra ocular tumour. For accurate localization of intraocular foreign bodies. Materials and Method: This is prospective study of 50 cases of patients with posterior segment abnormalities on B-Scan. Ultrasonic tissue density is known by focusing an echo on screen and then gradually decreasing sensitivity control till that echo disappear.Mobiliy of ultrasound abnormality is tested by asking the patient to move eyes while the probe is held stationary. Results: Cases with Corneal Opacity showed RD, VH, Dislocated IOL, Endophthalmitis and CD.Cases of Anterior Staphyloma showed VH with RD and RD. Cases of Traumativ Hyphema showed VH, VH with PVD, VH with PVD with Aphakia and FB in vitreous cavity. Cases of Occlusio Pupillae showed VH and Endophthalmitis. Conclusion: As utilized in ophthalmology, ultrasound both complement and surpasses the capabilities of other diagnostic technique in the evaluation of abnormalities, particularly those produced by ocular and orbital tumours,vitreous hemorrhage, trauma and foreign bodies.
