Summary
Idiopathic dermatomyositis can cause rare ocular motility disturbances, mimicking internuclear ophthalmoplegia. Early diagnosis and corticotherapy led to a favorable outcome in this case.
Area of Science:
- Neurology
- Ophthalmology
- Rheumatology
Background:
- Idiopathic dermatomyositis is a rare idiopathic inflammatory myopathy.
- Ocular muscle involvement is an uncommon manifestation of dermatomyositis.
Observation:
- A 60-year-old woman presented with diplopia and an ocular motility disturbance that mimicked internuclear ophthalmoplegia.
Findings:
- Diagnosis of idiopathic dermatomyositis was confirmed through clinical, biological, electrophysiological, and histological data.
- The patient experienced a favorable outcome with corticotherapy.
Implications:
- This case highlights the importance of considering dermatomyositis in patients with unexplained ocular motility disorders.
- Exclusion of other autoimmune disorders, such as myasthenia gravis, is crucial for accurate diagnosis and management.
