A fluorescein strip containing 10% fluorescein is applied topically to the affected area, without applying pressure on the eye due to the risk of tissue extrusion. The fluorescein is examined with a cobalt blue filter. At this point, the fluorescein appears green in color. Any changes in color or surface of the fluorescence area indicate the presence of corneal leakage. The test is contraindicated in obvious globe rupture, Full-thickness eye laceration, and fluorescein hypersensitivity.
