Summary
Chiari I malformation can cause isolated esotropia. Neurosurgical decompression resolved esotropia in two patients, while strabismus surgery offered temporary alignment, highlighting the need for individualized treatment strategies.
Area of Science:
- Ophthalmology
- Neurology
- Neurosurgery
Background:
- Chiari I malformation is a hindbrain anomaly.
- Isolated comitant esotropia can be a presenting sign.
Observation:
- Four patients with isolated esotropia were diagnosed with Chiari I malformation.
- Two patients underwent successful neurosurgical decompression with complete esotropia resolution.
- Two patients underwent strabismus surgery with variable and potentially temporary outcomes.
Findings:
- Neurosurgical decompression appears effective for esotropia associated with Chiari I malformation.
- Strabismus surgery may provide only temporary ocular alignment in these cases.
Implications:
- Management decisions for esotropia in Chiari I malformation require a case-by-case approach.
- Early neurosurgical intervention may be crucial for sustained esotropia correction.
