Anterior segment ischemia following strabismus surgery
Journal of Pediatric Ophthalmology and Strabismus
|September 1, 1984
Summary
Extensive eye muscle surgery, particularly on three or four muscles, appears safe for healthy patients. Anterior segment ischemia (ASI) risk is low, even with staged procedures, suggesting good outcomes.
Area of Science:
- Ophthalmology
- Surgical Complications
- Oculoplastics
Background:
- Anterior segment ischemia (ASI) is a serious complication following eye muscle surgery.
- ASI risk increases with the number of muscles operated on, especially in patients with thyroid dysfunction.
Observation:
- This study reviewed 34 eyes undergoing three- or four-muscle rectus surgery and 7 eyes with thyroid ophthalmopathy undergoing two- or three-muscle surgery.
- Follow-up ranged from seven months to eleven years.
Findings:
- Clinically significant ASI occurred in only one patient, presenting mildly with no visual loss.
- The overall incidence of ASI in this cohort was notably low.
Implications:
- Surgery on three or four rectus muscles in healthy patients is likely safe if performed in a staged manner.
- This suggests a potentially revised approach to extensive strabismus surgery, prioritizing patient safety and visual outcomes.
