Cataract is a treatable cause of blindness. A good post-operative outcome can be achieved with appropriate evaluation of unsuspected posterior segment disorders before the surgery by B san Ultrasonography evaluation. This study assess use B- scan ultrasonogram to visualize status of posterior segment of eye glob, hidden disorders and their percentage that affect the prognosis outcome of cataract surgery. A prospective study was done at the radiological department, using B -scan ultrasound examination of 151 patient candidates for cataract surgery, characterized as 128 patient of non-traumatized and 23 patient with a history of trauma for more than one month. Out of 151 patient, there was 38 patient (25.1%) with abnormal posterior segment disorders. In the non-traumatic group, out of 128 patient, there are 23 patients (17.96%) with abnormal posterior segment disorders. In the traumatic group, out of 23 patient, there are 15 patients (65%) of the abnormal posterior segment. The highest posterior segment disorder in non-traumatic cataract was retinal detachment of 10 patient (43.47%) and at traumatic patient of retinal detachment of 5 patient (33.33%) and vitreous body haemorrhage of 5 patient (33.33%). For patients with systemic risk factors as diabetes mellitus and hypertension, the most frequent lesion was vitreous haemorrhage. In conclusion B-scan ultrasonogram is highly valuable, sensitive and specific, and widely available for detection of posterior segment disorders and its recommended to be a routine examination before the cataract surgery.
