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. [1]
A seidel test detects more subtle or partially self-sealing open-globe injuries. Fluorescein dye is applied to the eye's surface to detect leakage of clear fluid originating from the wound using a Wood's lamp or blue light. [4] This test is avoided in obvious globe injury. [1]
Corneal perforation can be diagnosed by using the Seidel test. Any aqueous leakage is revealed during the Seidel test confirms corneal perforation. A fluorescence strip is wiped over the wound. If the clear aqueous humor from the eye runs through the yellow stain, the patient tests positive for corneal perforation.
