Purpose:
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.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
