leukoma

[lü′kō·mə]
(medicine)
A large and dense opacity of the cornea as a result of an ulcer, wound, or inflammation, which presents an appearance of ground glass.

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.

Subgroup 1 included patients with pterygium; subgroup 2 included patients with NV on a donor disc after penetrating keratoplasty; subgroup 3 included patients with other ocular pathology (corneal leucoma after alkali burns, vascularized scars after corneal ulcers, NV after herpetic keratitis, and Stevens-Johnson syndrome or corneal NV of another etiology); and subgroup 4 included patients under preparation for high-risk penetrating keratoplasty (Table 1).
The second most common cause is leucoma accounting for 20.91% (n=192) of total cases (n=918), and is also the most common cause of blindness due to anterior segment lesions accounting for 61.5% (n=192) of the cases.
