Background: Ultrasonography is useful in detecting significant abnormalities in eyes with opaque media like advanced cataracts. This can help in better surgical planning and predicting appropriate prognosis. Objective: To detect posterior segment eye diseases (PSEDs) in advanced cataracts by B- scan ultrasonography. Materials and Methods: One hundred and fifty patients attending in the event of non-visualization of fundus irrespective of age and gender were included in the study. All cases suspected to have orbital lesions, high risk extrusion of intraocular contents and previous history of ocular surgery were excluded from this study. Ultrasonography was done with the contact method. Results: The current study revealed that 17.3% of the patients had PSEDs. These included 6% cases of retinal detachment, 5.3% vitreous haemorrhage, 2.6% optic nerve head cupping, 2% posterior staphyloma and 1.3% posterior vitreous detachment. Conclusion: B-Scan ultrasonography is useful for the detection of hidden PSEDs in advanced cataract, which can help in better surgical planning and providing appropriate prognosis to the patients. Keywords: Advanced cataract, diabetic retinopathy, posterior segment, retinal detachment, vitreous haemorrhage and ultrasonography.
