What are Congenital Cataracts?

The term “congenital” refers to something present at birth, while a cataract is a clouding of the lens inside the eye, which normally focuses light for clear vision. Therefore, congenital cataracts are a condition where a baby is born with a cloudy lens in one or both eyes. This cloudiness disrupts the passage of light, affecting the baby’s vision and development.

What Causes Congenital Cataracts?

The reasons for congenital cataracts can vary and fall into two main categories:

• Genetic factors: Inherited mutations in certain genes play a role in some cases.
• Non-genetic factors: These include infections during pregnancy, such as rubella, cytomegalovirus, or toxoplasmosis. Other factors like maternal health issues, premature birth, and exposure to certain medications or toxins during pregnancy can also increase the risk.

Special Lenses for Babies

Unlike adults, babies’ eyes are still developing. Therefore, a special type of intraocular lens (IOL) is used during cataract surgery. These lenses are flexible and can grow with the child’s eye, ensuring proper vision throughout their growth.

Types of Congenital Cataracts

Congenital cataracts can be categorized based on their location and severity:

• Nuclear cataracts: Cloudiness affects the central part of the lens.
• Cortical cataracts: Spoke-like opacities appear in the lens cortex.
• Posterior subcapsular cataracts: Cloudiness occurs behind the lens capsule.
• Total cataracts: The entire lens becomes cloudy, significantly impacting vision.

Treatment for Congenital Cataracts

Early diagnosis and treatment are crucial for preventing permanent vision loss in babies with congenital cataracts. The treatment typically involves surgery to remove the cloudy lens and implant the special IOL. Additional therapies like patching or glasses may be needed to strengthen the developing visual system.

Prevention of Congenital Cataracts

While not always possible, some preventive measures can be taken:
