OBJECTIVE: The purpose of this study is to show how sonography can reveal pathology of the eye and to highlight its usefulness as a simple and cost-effective tool in investigating eye symptoms. CONCLUSION: The cystic nature of the eye, its superficial location, and high-frequency transducers make it possible to clearly show normal anatomy and pathology such as tumors, retinal detachment, vitreous hemorrhage, foreign bodies, and vascular malformations. Sonography is useful as a treatment follow-up technique because it has no adverse effects. Sonography is well tolerated by patients and relatively easy to perform for those familiar with real-time sonography.
