Quick answer
Leukoma (leucoma) is a dense, white scar or opacity of the cornea, the transparent front surface of the eye. If it involves the central cornea or pupil area, it can significantly blur vision.
Common causes
- Previous corneal ulcer or infection, including bacterial, fungal, or herpes infection
- Eye trauma or retained foreign body
- Chemical injury or burn
- Prior eye surgery
- Congenital corneal opacity in some children
Symptoms
- Visible white spot on the cornea
- Blurred or reduced vision
- Glare, halos, or light sensitivity
- Sometimes irregular astigmatism from an uneven scar
Treatment depends on cause, depth, and effect on vision
- Treat any active infection or inflammation urgently
- Glasses or rigid/scleral contact lenses may improve vision from scar-induced irregular astigmatism
- Superficial scars may sometimes be treated with procedures such as phototherapeutic keratectomy
- Dense or deep central scars may require corneal transplantation
A new white spot with pain, redness, discharge, light sensitivity, or falling vision is an eye emergency, particularly for contact-lens users. Seek same-day assessment by an ophthalmologist.
