BACKGROUND B- scan is ideal and accurate for evaluating ocular and extra ocular structures especially for small tumours of less than 3mm in size and fine detachments of layers. The main objective of this study is to evaluate the usefulness of high resolution B-mode ultrasonography in ocular and extra ocular lesions of eye in correlation with clinical and ophthalmological investigations. MATERIALS AND METHODS All patients referred to the Department of Radio-Diagnosis who are suspected to have ocular and extra ocular lesions in a period of 2 years from November 2014 to October 2016 were scanned using standard ultrasonography with 7-12 Mhz linear array transducer in real time along with colour doppler when required. RESULTS 50 cases presented with suspected ocular and extra ocular lesions of eye were evaluated with B-mode ultrasonography. Retinal detachment was seen in 12 patients, posterior vitreous detachment in 10, vitreous haemorrhage in 7, choroid retinal thickening in 6, vitreous floaters in 3, choroidal detachment in 3, retinoblastoma in 2, foreign body in posterior segment in 1, subluxated lens in posterior segment in 2, optic nerve thickening in 1, mucocele in 1, extra ocular muscle thickening in 1. CONCLUSION High resolution B-mode ultrasonography helps in diagnosing several pathologies of eye with accuracy, high clarity and high predictive value.
