[Results of early treatment of congenital strabismus]
Insights
Early treatment for congenital esotropia before 2 months old significantly improves binocular vision and reduces risks of manifest latent nystagmus (NML) and dissociated vertical deviation (DVD). This early intervention is key for better visual outcomes in children.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Neuroscience
Context:
- Congenital esotropia is a common condition affecting infant eye alignment.
- Early diagnosis and intervention are crucial for optimal visual development.
- Previous studies highlight the importance of timely treatment but lack specific age-based outcome data.
Purpose:
- To analyze the impact of very early treatment (before 6 weeks) versus later treatment (after 3 months) on visual outcomes in children with esotropia.
- To evaluate the incidence of key ophthalmological conditions, including dissociated vertical deviation (DVD) and manifest latent nystagmus (NML), based on treatment timing.
- To establish evidence-based recommendations for the optimal age of intervention for congenital esotropia.
Summary:
- Thirty-eight children with esotropia were divided into four groups based on treatment age.
- Children treated before 6 weeks (Groups 1 & 2) showed significantly better outcomes: no DVD, one NML, and 11 with binocular vision.
- Children treated after 3 months (Groups 3 & 4) had higher rates of DVD (4 cases) and NML (10 cases), with only 9 achieving binocular vision.
Impact:
- Supports the recommendation for initiating esotropia treatment before 2 months of age.
- Demonstrates a clear correlation between early intervention and improved chances of achieving binocular vision.
- Highlights the potential to reduce the long-term risks of NML and DVD through timely treatment of congenital esotropia.
Abstract:
The authors analyse the results obtained after very early treatment of Esotropia in 38 children. These children were divided into 4 groups according to their age at the time of treatment. At the age of 30 months, they studied binocular vision, manifest latent nystagmus (NML) and dissociated vertical deviation (DVD). In groups 1 and 2, treatment was instituted before the age of 6 weeks (13 children) no DVD was noted, only one NML and 11 children have binocular vision. In groups 3 and 4, treatment was instituted after the age of 3 months (25 children) 4 cases of DVD and 10 of NML are noted, and only 9 children have binocular vision. In case of congenital esotropia, the authors recommend treatment before 2 months old to obtain a possibility of binocular vision and to decrease the risk of NML and DVD.
