Cataract - congenital
Unlike most cataracts, which occur with aging, congenital cataracts are present at birth.
Congenital cataracts are rare. In most people, no cause can be found.
Congenital cataracts often occur as part of the following birth defects:
Congenital cataracts most often look different than other forms of cataract.
Symptoms may include:
To diagnose congenital cataract, the infant should have a complete eye exam by an ophthalmologist. The infant may also need to be examined by a pediatrician who is experienced in treating inherited disorders. Blood tests or x-rays may also be needed.
If congenital cataracts are mild and do not affect vision, they may not need to be treated, especially if they are in both eyes.
Moderate to severe cataracts that affect vision, or a cataract that is in only 1 eye, will need to be treated with cataract removal surgery. In most (noncongenital) cataract surgeries, an artificial intraocular lens (IOL) is inserted into the eye. The use of IOLs in infants is controversial. Without an IOL, the infant will need to wear a contact lens.
Patching to force the child to use the weaker eye is often needed to prevent amblyopia.
The infant may also need to be treated for the inherited disorder that is causing the cataracts.
Removing a congenital cataract is usually a safe, effective procedure. The child will need follow-up for vision rehabilitation. Most infants have some level of "lazy eye" (amblyopia) before the surgery and will need to use patching.
With cataract surgery there is a very slight risk of:
Infants who have surgery for congenital cataracts are likely to develop another type of cataract, which may need further surgery or laser treatment.
Many of the diseases that are associated with congenital cataract can also affect other organs.
Call for an urgent appointment with your baby's health care provider if:
If you have a family history of inheritable disorders that could cause congenital cataracts, consider seeking genetic counseling.
