Early surgical alignment for congenital esotropia

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Strabismus Surgery

Background:

• Congenital esotropia is a common form of strabismus in infants.
• Early surgical intervention is often recommended to achieve optimal visual outcomes.
• The precise timing for surgical alignment remains a subject of clinical importance.

Purpose of the Study:

• To investigate the relationship between the age of initial adequate surgical alignment for congenital esotropia and the development of binocularity.
• To determine if there is a critical age threshold for achieving successful binocular vision after surgical correction.

Main Methods:

• A clinical study involving 154 patients with congenital esotropia managed across three countries.
• Personal examination by the author, minimizing examiner bias by withholding prior clinical history.
• Standardized examination methods and devices were used, with 106 patients selected for analysis based on reliable data and confirmed congenital esotropia by age one.

Main Results:

• Sensory testing results showed no statistically significant difference in binocularity outcomes for patients aligned at 6, 12, or 24 months of age.
• Patients whose congenital esotropia was aligned after 24 months of age demonstrated a significantly lower percentage with evidence of binocularity (p < .001).

Conclusions:

• Delayed surgical alignment beyond 24 months of age for congenital esotropia is associated with a significantly reduced likelihood of developing binocular vision.
• These findings underscore the importance of timely surgical intervention in congenital esotropia to maximize the potential for binocular visual function.
