A cloudy cornea is a loss of transparency of the cornea.
Corneal opacification; Corneal edema
The cornea makes up the front wall of the eye. It is normally clear. It helps focus the light entering the eye.
Causes of cloudy cornea include:
- Sensitivity to non-infectious bacteria
- Ulcers on the eye
- River blindness
- Swelling due to glaucoma, birth injury, or Fuchs’ dystrophy
- Dryness of the eye due to Sjogren syndrome, vitamin A deficiency, and sometimes after LASIK eye surgery
- Dystrophy (inherited metabolic disease)
- Injruy to the eye, including chemical burns and welding injury
Consult your health care provider. There is no appropriate home care.
Call your health care provider if
Contact your health care provider if:
- The outer surface of the eye appears cloudy
- You have trouble with your vision
Note: It is appropriate to see an ophthalmologist for vision or eye problems. However, your primary health care provider may also be involved if a whole-body (systemic) disease is suspected.
What to expect at your health care provider’s office
Your doctor or nurse will examine your eyes and ask questions about your symptoms and medical history, such as:
- Did the cornea become cloudy quickly, or did it develop slowly?
- When did you first notice this?
- Does it affect both eyes?
- Is there any history of injury to the eye?
- Do you wear contacts?
- Do you have any trouble with your vision?
- If so, what type (blurring, reduced vision, or other) and how much?
Tests may include:
Biopsy of lid tissue
Computer mapping of the cornea (corneal topography)
Schirmer’s test for eye dryness
Special photographs to measure the cells of the cornea
Standard eye exam Ultrasoundto measure corneal thickness
