When Is This Test Needed?

Your healthcare provider may recommend an ocular ultrasound if you have symptoms like sudden vision changes, eye pain, swelling, or if they suspect conditions such as retinal detachment, cataracts, or tumors. It’s also used before certain eye surgeries to assess internal structures.

What to Expect During the Procedure

You’ll lie down with your eyes closed while a gel is applied to your closed eyelids. A handheld device emits sound waves that create images on a screen. The process is painless and typically takes about 15–30 minutes.

Common Uses and Conditions Evaluated

This test helps evaluate conditions like vitreous hemorrhage, glaucoma, diabetic retinopathy, or congenital eye abnormalities. It’s also used to guide procedures such as cataract surgery or retinal detachment repair.

Preparation and Safety

No special preparation is needed, but inform your provider about any medications or conditions that might affect the results. Ultrasound is generally safe and doesn’t involve radiation or invasive procedures.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical significance: Ocular ultrasound is critical for diagnosing and managing eye diseases that may not be visible through other imaging methods like MRI or CT scans. It provides real-time images for accurate assessment and treatment planning.
