Leukoma

corneal walleye, cicatricial changes in the cornea that more or less impair its transparency and penetrability by light.

Leukoma results from severe inflammations accompanied by severe injury to the corneal tissue or by ulceration (in gonorrhea, trachoma, tuberculosis, syphilis). It may also be a consequence of direct injury to the eye. Less commonly, it is congenital (inflammation during intrauterine development). The affected cornea acquires a characteristic whitish color, and visual acuity is diminished. Treatment involves the use of drugs (Dionin, mercuric ointment), physical therapy (diathermy, electrophoresis with potassium iodide), resorptive agents, tissue therapy, and keratoplasty.

leukoma

Dense, white, corneal opacity caused by scar tissue. A localized leukoma appears as a whitish scar surrounded by normal cornea. A generalized leukoma involves the entire cornea, which appears white, often with blood vessels coursing over its surface. Visual impairment depends on the location and extent of the leukoma. If the opacity is faint, it is called a nebula. Note: also spelt leucoma. See hyperacuity; corneal ulcer.
