To describe a divergence insufficiency in a young woman.
Methods
Case report.
Results
A 38-year-old woman presented with a episode of homonymus horizontal diplopia at distance. She was orthophoric at near but had esotropia at distance. Neurological evaluation was normal but multiple demyelinating lesions were shown in the magnetic resonance scan, with increased intrathecal Ig G production. Double vision improved after corticosteroid mega-doses.
Conclusions
An acute onset of diplopia due to divergence insufficiency in a young adult may be associated with a demyelinating disorder.
