Graded Marginal Recession: A Surgical Technique to Correct Small Angle Vertical Deviations.
Journal of Pediatric Ophthalmology and Strabismus
|March 29, 2016
Summary
This study introduces a new graded marginal recession technique for correcting small vertical strabismus in adults. The method shows promise for effectively treating small deviations and resolving double vision.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Adults with small angle vertical deviations and fusion potential often require surgical correction.
- Existing techniques may not precisely address very small deviations.
Observation:
- A novel graded marginal recession technique was applied to four adult patients with hypertropia (1-5 prism diopters).
- The procedure involved graded recession and tenotomy of vertical rectus muscle poles.
- A surgical nomogram was developed to guide the procedure.
Findings:
- Three out of four patients achieved successful strabismus correction and diplopia resolution.
- One patient experienced a small regression requiring further intervention.
- No complications or induced incomitance were noted in the successfully treated patients.
Implications:
- The graded marginal recession offers a safe and effective surgical option for very small vertical deviations in adults.
- The developed surgical nomogram aids in precise, incremental corrections (<0.5 PD).
- This technique expands the surgical armamentarium for managing subtle strabismus.
