What complications might congenital cataracts cause?

Because congenital cataracts can significantly impact a child's visual development, early diagnosis and treatment are essential. If left untreated, congenital cataracts can lead to permanent vision impairment or blindness in the affected eye(s).Some additional potential complications associated with congenital cataracts include:

  1. Amblyopia (Lazy Eye): When a cataract occurs in one eye, it can lead to a condition called amblyopia or "lazy eye." The brain may begin to favor the eye with clearer vision, causing the affected eye to weaken and not develop normal visual acuity. Early treatment, such as surgery and patching therapy, can help prevent or address amblyopia.
  1. Strabismus (Crossed Eyes): Untreated congenital cataracts can sometimes lead to misalignment of the eyes, causing one or both eyes to cross or deviate outward. This condition is known as strabismus and may require treatment to correct.
  1. Nystagmus (Involuntary Eye Movements): In some cases, congenital cataracts can lead to nystagmus, which is characterized by rapid, involuntary eye movements. Nystagmus can affect visual stability and clarity.
  1. Glaucoma: Congenital cataracts can sometimes increase the risk of developing glaucoma, a condition characterized by increased intraocular pressure that can damage the optic nerve and lead to vision loss. Regular monitoring is essential to detect and manage glaucoma if it occurs.
  2. Secondary Cataracts: After cataract surgery, particularly in young children, a secondary cataract can develop over time. This is known as posterior capsule opacification (PCO) and can cause vision problems. It is usually treated with a simple laser procedure called YAG laser capsulotomy.
  3. Reduced Depth Perception: Children with congenital cataracts may have reduced depth perception, making activities that require judging distances, such as catching a ball or navigating stairs, more challenging.
