A cloudy cornea is a loss of transparency of the cornea.
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)
- Injury to the eye, including chemical burns and welding injury
Consult your health care provider. There is no appropriate home care.
When to Contact a Medical Professional
Contact your health care provider if:
- The outer surface of the eye appears cloudy
- You have trouble with your vision
Note: You will need to see an ophthalmologist for vision or eye problems. However, your primary health care provider may also be involved if the problem could be due to a whole-body (systemic) disease.
What to Expect at Your Office Visit
The health care provider will examine your eyes and ask about your medical history. The two main questions will be if your vision is affected and if you have seen a spot on the front of your eye.
Other questions may include:
- When did you first notice this?
- Does it affect both eyes?
- DO you have trouble with your vision?
- Is it constant or intermittent?
- Do you wear contact lenses?
- Is there any history of injury to the eye?
- Has there been any discomfort? If so, is there anything that helps?
