J Sheikh Zayed Med Coll Jan ;2(1):140-3.

Background: Ophthatamic ultrasonography is a useful diagnostic tool for intraocular evaluation. Objectives: The objective of this study was to detect and characterize the ocular and orbital tumors with the help of B-scan ultrasound. Patients & Methods: This was a prospective descriptive study conducted in Sheikh Zayed Medical College/ Hospital, Rahim Yar Khan, for a period of two years from January 2009. Contact B- scan methodology with 7.5 MHZ linear probe was used in which probe was directly placed on closed eyelids. Scanning was performed in longitudinal as well as transverse planes and with eye movements in all directions. 51 consecutive patients of either sex and age were examined, referred from different ophthalmology centers and clinics having clinical suspicion of orbital masses. Results: Total 51 cases were examined, 27 (53%) were males and 24 (47%) were females. Right eye was involved in 51% cases, left was in 43% cases and both eyes were involved in 6% cases. Out of 51 cases, 88% cases were diagnosed to be extra ocular orbital tumors and 12% were intra ocular tumors. Among all tumor types, pseudo tumor was commonest variety and was 26%. Conclusion: Ultrasonography of eyes (B-scan) is non invasive, relatively cheaper and easily available method to diagnose orbital tumors.
