Lissamine Green Test
What is a lissamine green test?
The test involves a strip of paper containing a special dye (lissamine green) which is diluted with saline, and then carefully dropped into your eye. The unique colour allows specialist to specifically see if you have dry cell patches in your eye.
How is the test carried out?
The test is carried out by your GP, Optometrist (optician) or Ophthalmologist (hospital eye doctor). The specialist will take a strip of paper containing a special dye (lissamine green) and dilute it with saline. This is then carefully dropped into your eye.
After a minute the specialist will shine a light into your eyes, using a slit lamp. The unique colour from the dye allows the specialist to specifically see if you have any dry or damaged cell patches in your eye.
Do I need to prepare for the test?
You do not need to prepare for the test, however, if you wear contact lenses or glasses you will need to remove them first.
How will the test feel?
You should not feel anything when the drops are first put into your eyes. Although some may feel a slight tingling sensation when the dye is first applied. If this does happen to you, after a few moments you should no longer feel uncomfortable.
How long will the test take?
The test is quite quick and should only take a few minutes.
