What is it?
A small probe with gel is placed on the closed eyelid and moved gently while you look in different directions. The sound waves show whether the retina is attached, whether there is blood or a tumour, and whether a foreign body is present.
When a B-scan is needed
- Vitreous haemorrhage
- Dense cataract before surgery, to check the retina
- Eye injury
- Suspected tumour inside the eye
How the test is done
- Test
Gel on the closed eyelid; painless; about 10 minutes.
- Result
The doctor explains the result the same visit.
