Masked bilateral superior oblique paresis
Journal of Pediatric Ophthalmology and Strabismus
|March 1, 1981
Summary
Masked bilateral superior oblique paresis was found in 9% of cases and often unsuspected. Bilaterality should be presumed in all superior oblique paresis cases until proven otherwise.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
- Strabismus
Background:
- Superior oblique paresis (SOP) is a common cause of vertical strabismus.
- Diagnosis can be challenging, especially in its masked or atypical presentations.
Observation:
- A significant proportion of patients (9 out of 57) presented with unsuspected masked bilateral superior oblique paresis.
- Contralateral inferior oblique overaction was a key finding in these cases.
Findings:
- Masked bilateral superior oblique paresis is more prevalent than previously recognized.
- The presence of superior oblique paresis warrants a high index of suspicion for bilaterality.
Implications:
- Clinical examination protocols should be adapted to systematically detect bilateral SOP.
- Early and accurate diagnosis of bilateral SOP is crucial for effective management and preventing long-term visual disturbances.
