Background: Cataract is defined as opacity within the clear lens inside the eye that reduces the amount of incoming light and results in deterioration of vision. Hence; the present study was conducted for assessing intraocular pathologies detected by preoperative B-Scan ultrasound examination in patients having dense cataracts. Materials & methods: A total of 100 patients were enrolled. Data pertaining to socio-demographic and other clinical correlates were collected using pre designed structured performa attached. The procedure was explained briefly to the patient for their co-operation. B-scan ocular examination was done using ultrasound machine. If any posterior pathology was detected during basic screening, it was centered on the right side of the echogram to achieve greatest resolution. On follow-up of the patients after cataract extraction surgery, the efficiency of B-Scan ultrasonography was done by comparing the diagnosis post-operatively when fundus was visible clinically by both direct and indirect ophthalmoscope. Results: Bilateral involvement occurred in 2 percent of the cases. Senile cataract was seen in 70 percent of the cases. Traumatic cataract was present in 10 percent of the cases. B Scan findings showed normal appearance in 60 percent of the patients while it showed abnormalities in 40 percent of the patients. Posterior vitreous detachment and vitreous degeneration were present in 12 percent and 15 percent of the patients respectively. Posterior vitreous detachment + Vitreous haemorrhage were seen in 8 patients. Overall sensitivity and specificity of B Scan was 97.5 percent and 100 percent respectively. Conclusion: B Scan is a magnificent tool in detecting intraocular pathologies in patients having dense cataracts.
