It is used as a screening test for many corneal disorders including corneal post-trauma, corneal perforation and corneal degeneration. NameThe Seidel Test is named after the German Ophthalmologist Erich Seidel (1882–1948). PrecautionsDo not apply pressure on the eye during the test due to the risk of tissue extrusion. ProcedureA fluorescein strip containing 10% fluorescein is applied topically to the affected area and 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. Results of the testIf the fluorescein strip turns pale upon application to the corneal surface, the person tests positive for the corneal deformity he/ she is being tested for. The change in the color of the fluorescein strip is due to dilution of fluorescein caused by the aqueous leakage in the cornea. See also
