B-SCAN ULTRASOUND

B-scan ultrasound is a safe, non-invasive imaging test that lets your doctor see the inside of the eye when direct view is limited. It uses high-frequency sound waves to create real-time images of the eye and orbit. As a result, it helps detect problems behind the iris and lens, even when media opacity blocks the view.

WHAT THIS SERVICE DOES

This test shows the vitreous, retina, choroid, and optic nerve head. It helps identify retinal detachment, vitreous hemorrhage, tumors, and other posterior segment conditions. Therefore, it guides diagnosis when cataract, corneal opacity, or dense hemorrhage prevents a clear view.

HOW THE TEST IS PERFORMED

First, the clinician places a small amount of gel on the closed eyelid or on the eye with topical drops, depending on the method. Next, a handheld probe sends sound waves into the eye. Then, returning echoes form an image on the screen. The test usually takes a few minutes and requires simple eye movements during scanning.

WHO MAY BENEFIT

B-scan ultrasound helps patients when standard examination cannot visualize the retina clearly. For example, it may be useful in the following cases.

1. Dense cataract blocking the view of the retina
2. Suspected retinal detachment or tear
3. Vitreous hemorrhage or floaters with poor visibility
4. Eye trauma requiring internal assessment
5. Evaluation of intraocular or orbital masses

PATIENT COMFORT AND SAFETY

This test is painless and does not use radiation. Most patients tolerate it well. In addition, the probe does not enter the eye during routine scanning. Patients can return to normal activities immediately after the test.

CLINICAL VALUE

B-scan ultrasound provides critical information when direct visualization is not possible. It supports early detection of serious conditions and helps guide treatment planning. Therefore, it plays an important role in both emergency and routine eye care.
