Bottom Line

Salzmann nodular degeneration causes raised gray-white bumps on the cornea. It can blur vision, cause glare, or feel like something is in the eye.

Salzmann nodular degeneration is a slow corneal surface disease. It causes raised bluish gray or whitish nodules on the clear front window of the eye 1.

Some people have no symptoms. Others notice blur, glare, dryness, or a foreign-body feeling when nodules change the smooth corneal shape.

Treatment starts with surface comfort and dry eye care. Larger or vision-changing nodules may need superficial keratectomy or laser smoothing 2.

Symptoms

Symptoms can be mild or very bothersome:

  • Blurred vision. The cornea surface becomes irregular.
  • Glare or starbursts. Light bends unevenly through the cornea.
  • Foreign-body feeling. A raised area can irritate the lid.
  • Dryness. Dry eye and lid disease may overlap.
  • Changing prescription. Glasses may stop working well.

Salzmann nodular degeneration is usually slow and noninflammatory 1.

Treatment

Treatment starts with the eye surface:

  • Lubricating drops. These reduce friction.
  • Lid and dry eye care. Treating inflammation may reduce irritation.
  • Specialty contact lenses. Scleral lenses may help selected patients.
  • Superficial keratectomy. The surgeon removes raised tissue from the cornea surface.
  • Laser smoothing. A cornea laser may smooth remaining irregularity.

Phototherapeutic keratectomy has been studied for Salzmann nodular degeneration, but recurrence can happen 4.

Living With Salzmann Nodules

Many people are watched if vision is stable and symptoms are mild. Follow-up matters when nodules are near the center of vision.

Tell your doctor if glare, blur, or prescription changes affect driving or reading. Treat dry eye and eyelid disease even if surgery is not needed.
