Early Onset Cataracts

Top 10 Things to Know About Pediatric Cataracts

Posted on

Pediatric cataracts present a unique set of challenges that differentiate them from cataracts in adults. Dr Courtney Kraus, a specialist in pediatric anterior segment diseases at the Wilmer Eye Institute at Johns Hopkins, recently sat down with Ophthalmology 360 to discuss insights into this specialized field. Presented here are 10 key insights to equip ophthalmologists with essential knowledge about pediatric cataract:

  1. Unique Signs and Symptoms

Children can’t communicate visual troubles verbally. Early-onset cataracts are often detected through newborn exams or visits to pediatricians.

Parents may observe a white pupil, contrasting with the typical red reflex.

  1. Diverse Risk Factors

Pediatric cataracts can result from various causes, including genetic predisposition, familial inheritance, or secondary to systemic conditions acquired later in childhood.

Preventive measures include trauma prevention and maternal vaccination against rubella.

  1. Diagnostic Challenges

In pre-verbal children, clinical exams play a crucial role in diagnosis.

Tools like a retina scope aid in assessing the extent and location of the cataract within the visual axis.

  1. Complexities in Treatment

Unlike adults, children are still growing, making cataract removal a delicate decision.

Surgery affects a child’s ability to focus on near objects, necessitating post-operative adjustments.

  1. Genetic Factors

Familial hereditary cataracts can be passed down with an autosomal dominant inheritance pattern.

Collaboration with ocular and pediatric geneticists aids in understanding syndromic conditions associated with cataracts.

  1. Range of Treatment Options

Treatment choices are determined by factors like size, location, density, and laterality of the cataract.

Non-surgical interventions such as glasses, patching, and dilating eye drops are also employed.

  1. Potential Complications

Glaucoma is a significant concern following pediatric cataract surgery. Timing of surgery plays a crucial role in minimizing this risk.

While all surgery carries inherent risks, complications like infections and retinal detachments are rare in the context of pediatric cataracts.

  1. Age Influences Prognosis

The age at diagnosis impacts surgical planning and risk assessment for complications like glaucoma.

Visual development is particularly critical in the first seven years of life, emphasizing the importance of early intervention.

  1. Long-term Implications

Intervention during the critical period of visual development is crucial for preventing irreversible amblyopia (lazy eye).

Even with optimized surgical outcomes, children with traumatic cataracts may still experience a preference for the non-involved eye.

  1. Collaborative Care is Key

Successful management of pediatric cataracts often involves an interdisciplinary team.

Collaboration with geneticists, pediatric anesthesiologists, and pediatricians is essential, especially in cases involving other health conditions or syndromes.

In managing pediatric cataracts, a holistic approach that considers the child’s growth, individual characteristics, and potential genetic factors is vital. This comprehensive care ensures the best possible outcomes for these young patients.
