Background Antibodies to a muscle-specific receptor tyrosine kinase (MuSK) have been found in approximately 40% of patients with generalized myasthenia gravis who are seronegative for the antiacetylcholine receptor antibody. Many of the patients with anti-MuSK antibodies have prominent oculobulbar symptoms or weakness of the neck and respiratory muscles, but patients with ocular myasthenia have not been described.
Objective To report a case of ocular myasthenia due to anti-MuSK antibodies.
Patient A young woman with ocular myasthenia and antibodies to MuSK.
Results Anti-MuSK antibody was detected by radioimmunoassay using highly purified MuSK recombinant antigen.
Conclusion Ocular myasthenia gravis is a presentation of the anti-MuSK antibody syndrome.
