Insights
Secondary strabismus in children with aphakia is most common when deprivation begins before age two. Esotropia dominates early, shifting to exotropia by age ten.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Strabismus
Context:
- Secondary strabismus is a common complication in children with aphakia.
- Congenital cataracts and perforating eye injuries are primary causes of aphakia in children.
- Understanding the timing and type of strabismus is crucial for effective management.
Purpose:
- To investigate the relationship between the onset of visual deprivation and the development of secondary strabismus in children with aphakia.
- To determine the frequency and polarity (esotropia vs. exotropia) of strabismus based on the age of deprivation onset.
Summary:
- This retrospective study analyzed 131 children with mono- and bilateral aphakia.
- Strabismus frequency was highest in children deprived of vision before age two.
- Esotropia was prevalent in the first two years, while exotropia increased to 80% by the end of the first decade.
Impact:
- Findings highlight the critical early period for visual development and the risk of strabismus in aphakic children.
- Informs early detection and intervention strategies for visual impairment in pediatric aphakia.
- Provides insights into the natural history and evolving patterns of strabismus in this population.
Abstract:
The frequency and polarity of secondary strabismus was related retrospectively to the onset of deprivation in 131 children with mono- and bilateral aphakia after congenital cataract or perforating injury. The frequency was highest in patients up to 2 years of age at the onset of deprivation. From the 3rd year on, it declined to 50% or less. Esotropia was predominant in the first 2 years of life. At the end of the first decade of life exotropia was up to 80%.
