RESUMO
Objective: To determine the usefulness of B-scan ultrasonography and to observe the relative frequency of conditions for which ultrasound B-scan examination was requested in Ophthalmology. Design: A descriptive study. Setting: Department of Ophthalmology, Ziauddin Medical University and Dr Akil Bin Abdul Kadir Welfare Eye Hospital Karachi, Sindh - Pakistan, from February 2002 to March 2005
Methods: We performed 320 B-scans over a period of 3 years. Patients were selected from out patient department. We used "SONOMED" and ALCON ultrasound machines
Results: In the total 320 ultrasounds performed, 102 did not demonstrate any pathology on Bscan ultrasonography. Vitreous disorders were present in 98 patients, 58 showed retinal detachment, 16 showed intraocular tumors and tumor like conditions, 9 patients showed optic nerve lesions and 6 patients showed intraocular foreign bodies. The remaining 31 patients had different types of miscellaneous lesions
Conclusion: Diagnostic ultrasonography has proved to be very helpful method for medical diagnosis in Ophthalmology. Opacities in the vitreous were the commonest problems followed by retinal detachment for which ultrasound was advised. It is also important to correlate B-scan findings to the clinical condition of patient
