Department of Medicine, South Buffalo Mercy Hospital, University at Buffalo, Buffalo, NY, USA. Convergence eye movements are usually preserved and thus demonstrate intact medial rectus innervation [1]. Differential Diagnosis Nuclear or fascicular third nerve palsy is typically due to midbrain infarction from occlusion of a small penetrating artery from the proximal PCA. Oculomotor nerve palsies, or third nerve palsies , result in weakness of the muscles supplied by the oculomotor nerve, namely the superior rectus, inferior rectus, medial rectus, inferior oblique, and levator palpebrae superioris muscles. (See also Overview of Neuro-ophthalmologic and Cranial Nerve Disorders .) In some cases pontine demyelinative lesions that affect the outputs of the VI nucleus (ie, both the medial longitudinal fasciculus, carrying the projections to the medial rectus subnucleus of III for adduction, and the abducens fascicle) can cause a nonselective gaze palsy that mimics a VI nuclear lesion (79). 3). Clipboard, Search History, and several other advanced features are temporarily unavailable. Increased intracranial pressure . oblique palsy, as covered in Chapter 19. Leigh RJ, Zee DS. In addition, other findings such as vertical gaze evoked nystagmus (most commonly on supraduction) can be seen.

Treatment of symptoms associated with CN VI palsy includes patching, prism, injection of botulinum toxin (Botox) into the medial rectus, or extraocular muscle surgery if the esotropia is longstanding. Sixth cranial nerve palsy refers to dysfunction of the sixth cranial nerve (abducens nerve). This is likely due to the susceptibility of the long-coursing basilar artery and its terminal branches to ischemia [5]. Midbrain infarction presenting with monocular elevation palsy and ptosis: topographic lesion analysis. Tsai TH, Demer JL. Reply to comments on: Acute isolated medial rectus palsy due to infarction as a result of a hypercoagulable state.

A loss of cross-talk between cranial nerve VI and cranial nerve III produces defects in conjugate eye movements that produce gaze. However, during surgery, anomalous posterior insertion of the medial rectus muscle was found, and the Hummelsheim operation was performed to correct the exotropia. Notably, the absence of concomitant neurological signs, such as vertigo, ataxia, sensory symptoms, dysarthria, facial palsy, or pyramidal tract dysfunction, has been shown to be significantly correlated with a more rapid recovery [1, 5]. Eventually, the correct diagnosis was established with cerebral MR imaging. Isolated Medial Rectus Nuclear Palsy as a Rare Presentation of Midbrain Infarction. -.
