Summary
Persistent intractable diplopia after strabismus surgery is rare in adults. Preoperative prism testing can help identify patients at low risk, but its predictive value for postoperative diplopia is limited.
Area of Science:
- Ophthalmology
- Strabismus Surgery
- Diplopia Research
Background:
- Adult strabismus surgery is performed for long-standing, constant deviations.
- Diplopia is a potential complication following strabismus surgery.
Purpose of the Study:
- To determine the incidence of persistent intractable diplopia after strabismus surgery in adults.
- To identify predictive tests for postoperative diplopia.
Main Methods:
- Retrospective review of 424 adult patients undergoing strabismus surgery.
- Preoperative testing with prisms to simulate surgical outcomes was analyzed.
Main Results:
- 0.8% of patients developed persistent intractable diplopia.
- Preoperative diplopia with prisms was associated with increased risk of postoperative diplopia (P<.001).
- Preoperative prism testing showed high sensitivity (100%) but low positive predictive value (2-28%) for postoperative diplopia.
Conclusions:
- Persistent intractable diplopia is a rare complication of adult strabismus surgery.
- Preoperative prism testing can identify patients with minimal risk of diplopia.
- A small group of patients with a definite risk of intractable diplopia may be identified preoperatively.
