Purpose: To examine the accuracy of non-ophthalmic ultrasonography in detecting intraocular pathology in eyes with opaque media.

Methods: This was a prospective observational study conducted on the eyes with opaque media. The radiologist performed non-ophthalmic ultrasound for detecting intraocular pathology prior to the ophthalmologist's assessment.

Results: Of the 95 eyes of 94 patients enrolled in the study, 14 eyes(14.7%) showed evidence of a posterior segment pathology on the ultrasonogram and all were correctly identified(true positive). One eye was false positive. The underlying conditions were retinal detachment (7 eyes; 7.4%), posterior vitreous detachment (5 eyes; 5.2%), asteroid hyalosis (1 eye; 1.1%), and intraocular foreign body (1 eye; 1.1%). The sensitivity and specificity were 100% (95% CI, 73–100%) and 99% (95% CI, 92–99%).

Conclusions: Non-ophthalmic ultrasound is highly accurate for ruling out and may have a role in diagnosing intraocular pathology in patients presented with opaque media.
