ABSTRACT
To determine the sensivity and specifity of ocular ultrasonography in detecting vitreoretinal lesion prior to deep vitrectomy in patients with opaque media. The hospital records of patients undergoing deep vitrectomy in a defined period at Shiraz Khalili hospital were reviewed. Sonographic reports given by a sinologist and operation reports given by a vitreoretinal fellowship were compared regarding significant clinical problems in five groups: intraocular foreign bodies, retinal detachment, choroidal detachment, posterior globe rupture, and significant vitreous opacities. From 42 sonographic reports, sensitivity of sonography was 100% for detection of vitreous opacity, posterior globe rupture, and intraocular foreign bodies; 90% for retinal detachment; and 71.4% for choroidal detachment. The specificity of sonography for all of the above mentioned pathologies was over 80% except for determination of significant vitreous opacities that was 71.4%. In this five group of vitreoretinal lesions, sonographic reports were accurate and were reliable for surgical planning and decision making in our setting
