Ophthalmoparesis can result from disorders of various parts of the eye and nervous system:
The orbit of the eye, including mechanical restrictions of eye movement, as in Graves disease.
The muscle, as in progressive external ophthalmoplegia or Kearns-Sayre syndrome.
The neuromuscular junction, as in myasthenia gravis.
The relevant cranial nerves (specifically the oculomotor, trochlear, and abducens), as in cavernous sinus syndrome or raised intracranial pressure.
The brainstem nuclei of these nerves, as in certain patterns of brainstem stroke such as Foville's syndrome.
White matter tracts connecting these nuclei, as in internuclear ophthalmoplegia, an occasional finding in multiple sclerosis.
Dorsal midbrain structures, as in Parinaud's syndrome.
Certain parts of the cerebral cortex (including the frontal eye fields), as in stroke.
Toxic envenomation by mambas, taipans, and kraits.
Thiamine deficiency can cause ophthalmoparesis in susceptible persons; this is part of the syndrome called Wernicke encephalopathy. The causal pathway by which this occurs is unknown. Intoxication with certain substances, such as phenytoin, can also cause ophthalmoparesis.
