Summary
Symptomatic cyclotropia, a form of double vision, was identified in patients with complex strabismus. Surgical correction of this cyclotropia effectively resolved the diplopia in most cases.
Area of Science:
- Ophthalmology
- Strabismus Surgery
- Neuro-ophthalmology
Background:
- Diplopia can arise from various ocular conditions, including strabismus and post-surgical complications.
- Prism adaptation is a common method for managing diplopia, but it is not always effective.
- Disruption of fusion is a suspected cause of persistent diplopia in complex cases.
Purpose of the Study:
- To investigate the underlying cause of persistent diplopia in patients with a history of complex ocular conditions.
- To determine if symptomatic cyclotropia, unrelated to oblique muscle dysfunction, is a significant factor in these cases.
- To evaluate the efficacy of surgical correction for cyclotropia in resolving diplopia.
Main Methods:
- A cohort of 15 patients with persistent diplopia was studied.
- Patients had a history of conditions such as scleral buckling, penetrating keratoplasty, or long-standing strabismus.
- Diagnosis involved assessing for cyclotropia unresponsive to prism correction.
Main Results:
- Fifteen patients with complex ocular histories presented with diplopia unresponsive to prisms.
- All patients were found to have significant symptomatic cyclotropia.
- Surgical correction of cyclotropia successfully resolved diplopia in 13 out of 15 patients.
Conclusions:
- Symptomatic cyclotropia is a key cause of persistent diplopia in patients with complex ophthalmic histories.
- Surgical management of cyclotropia offers a viable solution for refractory diplopia.
- This finding highlights the importance of assessing for cyclotropia in challenging strabismus cases.
