Corneal opacity is a disorder of the cornea, the transparent structure on the front of the eyeball, which can cause serious vision problems. Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina and may cause the cornea to appear white or clouded over.
There are many causes of corneal opacity. In some cases, your doctor can recommend a treatment that will reverse the opacity and lessen your chance of needing additional treatment, such as surgery.
Infection, injury, or inflammation of the eye are the most common causes of corneal opacity.
The following factors increase your chance of developing corneal opacity. If you have any of these risk factors, tell your doctor:
If you experience any of these symptoms, do not assume it is due to corneal opacity. These symptoms may be caused by other health conditions as well. If you experience any one of the following, see your eye doctor immediately:
Vision decrease or loss
Pain in the eye or feeling like there is “something in your eye”
Eye redness or light sensitivity
Area on the eye that appears cloudy, milky, or is not completely transparent
Your doctor will ask about your symptoms and medical history, including illnesses and injuries, and perform a physical exam.
To prepare for a comprehensive eye exam, your doctor may put drops in your eyes to numb them and to dilate the pupils. Your doctor will use a slit lamp (specialized microscope) to focus a high powered beam of light into your eye to examine the cornea and other structures in your eye.
Talk with your doctor about the best treatment plan for you. Treatments vary depending on the most likely cause of the scarring and how severe the scarring is. Treatments may include:
Eye drops containing antibiotics, steroids, or both
In some cases, scar tissue may be removed surgically. The surgery may be performed using a laser, called phototherapeutic keratectomy (PTK), if the scarring is close to the corneal surface.
In more severe cases, a
may be necessary.
To help reduce your chance of developing corneal opacity, take the following steps:
Take care to avoid injuring the eye. Wear eye protection during any potentially dangerous activity. Make sure the safety goggles are worn tight against the face, otherwise a foreign body can fly up under the goggles and injure the eye.
Take proper care of contact lenses, and follow your doctor’s recommendations regarding wear and cleaning.
See your doctor immediately if you suspect you have an eye infection, including conjunctivitis (pink eye), if you injured your eye, or if you develop any pain or change in vision.
