Summary
Strabismus surgery rarely causes serious complications, but scleral perforation risk is ~1%. This case highlights a rare globe rupture during superior rectus recession due to extreme scleral thinning.
Area of Science:
- Ophthalmology
- Ophthalmic Surgery
Background:
- Strabismus surgery aims to correct eye alignment.
- Scleral perforation is a known, though uncommon, risk (~1%) during strabismus procedures, typically without severe outcomes.
Observation:
- A patient undergoing superior rectus muscle recession for strabismus experienced sudden globe rupture.
- This was attributed to an unidentifiable, localized region of extreme scleral thinning near the muscle insertion site.
Findings:
- The globe rupture represents a severe, previously unreported complication of strabismus surgery.
- Risk factors for perforation include myopia and recession procedures, but this case involved extreme thinning.
Implications:
- Highlights the potential for catastrophic complications even in routine ophthalmic procedures.
- Suggests the need for heightened awareness and potentially modified surgical techniques in cases with suspected scleral thinning.
