Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Adjustable Suture Strabismus Surgery
Advanced surgical technique allowing fine-tuning of muscle position in the immediate post-operative period while the patient is awake. Provides enhanced precision in achieving optimal eye alignment compared to standard techniques.
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Botulinum Toxin Injection
Targeted injection of botulinum toxin into overactive extraocular muscles to temporarily weaken them and improve eye alignment. Effects typically last 3-4 months and may require repeated treatments.
Additional treatment options
Binocular Vision Training
Computer-assisted and hands-on exercises to improve fusion capacity and depth perception. Programs are customized based on the specific nature of the congenital fibrosis presentation.
physical_therapyEnvironmental Modifications
Adjustments to home and school environments to accommodate visual limitations, including proper lighting, seating positioning, and use of assistive technologies for reading and close work.
lifestyleSerial Orthoptic Assessments
Regular quantitative measurements of ocular motility, alignment, and sensory status to track disease stability and inform timing of surgical intervention. Includes standardized photographic documentation.
