The oculomotor nucleus, located in the midbrain, can be affected if the blood supply to the midbrain is decreased. 6 Patients may also present with nausea, vertigo, and other cranial nerve or neurologic deficits. [aafp.org]

There may be associated symptoms such as ptosis, eye pain (with or without eye movement), headache and nausea. Signs/examination Check for ptosis, which is often the first sign of weakness. [patient.info]

· Vertigo and nausea: They are partly due to diplopia, and partly due to false orientation. · Secondary angle of deviation is more than the primary deviation. · Restriction of ocular movements in the direction of action of paralyzed muscle. · Compensatory [thamburaj.com]

The term 'Diplopia' is derived from the Greek; diplous meaning double and ops meaning eye. Diplopia causes significant difficulty with depth perception and orientation of objects. [thamburaj.com]

Diplopia was relieved by performing surgery in both the affected eye (right medial rectus resection) and the healthy eye (left lateral rectus muscle recession). [jeos.eg.net]

Diplopia may be a complication after refractive surgery. Ocular lesions, including diplopia, can be amongst the presenting features of Creutzfeldt-Jakob disease (CJD), especially new variant CJD [ 4 ]. [patient.info]

A few key points once more: The oculomotor palsy is characterized by unilateral ptosis and an eye that is down and out. Pupil dilation suggests compression, possibly by berry aneurysm. [eyes.gp-surgery.com]

Other patterns of weakness cannot occur with nuclear lesions, such as III nerve palsy with unilateral ptosis or unilateral mydriasis. [neuroophthalmology.ca]
