Accommodative esotropia during the first year of life
Insights
High hyperopia in infants may indicate accommodative esotropia, a condition where eyes turn inward. Early detection and correction of significant hyperopia are crucial for proper eye alignment in young children.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Strabismus Research
Background:
- Accommodative esotropia is a common form of strabismus in infants and young children.
- It is often associated with uncorrected hyperopia (farsightedness).
Observation:
- Two infants presented with esotropia within their first six months of life.
- Both infants had significant hyperopia (4.50 and 3.50 diopters, respectively).
- Eye alignment was fully corrected with appropriate hyperopic correction.
Findings:
- High degrees of hyperopia (exceeding +3.00 diopters) in infants aged 4-6 months warrant consideration for accommodative esotropia.
- Even small angles of esotropia should be evaluated for an underlying accommodative component when significant hyperopia is present.
Implications:
- Early screening for hyperopia in infants is vital for identifying potential causes of esotropia.
- Prompt refractive correction can lead to complete alignment in cases of infantile accommodative esotropia.
- This highlights the importance of considering refractive error as a primary cause of esotropia in very young children.
Abstract:
Two infants developed accommodative esotropia during their first six months of life. One infant, whose age at onset was 4 1/2 months, had 4.50 diopters of hyperopia. The second infant, whose age at onset was 5 months, had 3.50 diopters of hyperopia. In both infants, the eyes completely aligned with hyperopic correction. Two points are stressed. First, when the amount of hyperopia exceeds +3.00, consideration should be given to an accommodative element as the cause of the esotropia, even if the child is only 4 to 6 months old. Second, even with small angles of esotropia, an accommodative element should be considered, if there is a substantial amount of hyperopia.
