Abstract

Myasthenia Gravis is an organ-specific autoimmune disorder generaly thought to be caused by an antibody-mediated attack against the skeletal muscle nicotinic acetylcholine receptor (AChR) at the neuromuscular junction. Not infrequently there may be other diseases accompanying myasthenia, that can give different neuro-ophtalmological manifestations or neurological syndromes with autoimmune substrate. By these autoimmmune diseases we note:Autoimmune thyroiditis, Systemic lupus erythematous, Dermatomyositis, i.e. The extraocular muscle weakness is present at 90% of myastenia patients. While anti-AChR are detectable in the majority of patients with generalized myasthenia, at patients with ocular myasthenia these antibodies are nearly undetectable. On the another hand, epidemiological, clinical and immunoserological studies, suggests that the ocular myasthenia and generalized myasthenia are two separate disorders. Both Myasthenia Gravis forms could be associated with other autoimmune disturbances with ocular impact, for example such as Autoimmune thyroiditis Ophtalmopathy.
