Fluorescein, a yellow dye, is either injected into the bloodstream through a vein in the hand or arm and/or taken by mouth as a drink.

Preparing for the Test

- Contact lenses must be removed before dilation and the test starts.

- sulfa antibiotics
- any medicines
Also, tell the health care provider if your child has a history of chest or breathing problems or is pregnant or breastfeeding.
During the Test
