“…The oculomotor parasympathetic axons are located superficially on the medial side of CN III, subsequently if the neuropathy initiates in this location it is likely that only the parasympathetic component will be affected. The clinical signs were unilateral in all dogs in this study, similar to the reported canine cases of idiopathic facial neuropathy but different to trigeminal neuropathy . There are several cases published of unilateral idiopathic trigeminal neuropathy in dogs, however the majority are bilaterally affected .…”

“…The mean recovery time of motor function was 5 weeks in the present study, similar to other idiopathic cranial neuropathies; however, a third of the cases affected with CN III motor dysfunction (4/11 dogs) in our study showed no signs of improvement. This finding differs from trigeminal neuropathy where the motor function recovered in all cases; but similar to facial neuropathy, where resolution of clinical signs was only seen in half of the affected dogs . Some degree of mydriasis persisted in all cases in our study; however, almost a quarter of patients recovered partial CN III parasympathetic function.…”

Ophthalmoplegia/ophthalmoparesis (internal, external, or both) has been reported in dogs secondary to neoplasia affecting the oculomotor nerve and is usually given a poor prognosis. The purpose of this retrospective study was to describe the clinical findings, magnetic resonance imaging (MRI) findings, management, outcome, and follow-up in a group of canine cases with idiopathic oculomotor neuropathy. Inclusion criteria included cases with ophthalmoplegia/ophthalmoparesis (internal, external or both) as sole neuroophthalmologic signs, complete ophthalmic and neurologic examination, head MRI, and a minimum follow-up period of 1 year. Dogs with progressive neurological signs not related to oculomotor neuropathy were excluded. Fourteen cases met the inclusion criteria. All cases were unilaterally affected. Magnetic resonance imaging showed equivocal enlargement of the oculomotor nerve in three cases, mild enlargement in five, and marked enlargement in six. Contrast enhancement was present in 12 cases, being marked in six. When present, the contrast enhancement was focal in eight cases and diffuse in four. The median follow-up time was 25 months. External ophthalmoparesis improved in seven cases, five cases under no treatment and two under systemic corticosteroid therapy. The clinical signs in the other seven cases remained unchanged. Idiopathic oculomotor neuropathy should be included as a differential diagnosis in dogs presenting with unilateral ophthalmoplegia/ophthalmoparesis (internal, external, or both) with the absence of other neurologic and ophthalmic signs, and with the MRI findings restricted to the oculomotor nerve. Idiopathic oculomotor neuropathy has a good prognosis as the clinical signs do not deteriorate and they can improve without treatment.

“…PVD combined with facial nerve deficits was presumably induced by idiopathic conditions in the current study population. In other studies similar findings of concurrent facial nerve palsy with idiopathic vestibular syndrome were described and different hypotheses were discussed (Garosi et al 2001, Jeandel et al 2016. Underlying inner ear disease could possibly not be detected using MRI if lesions were very small (Garosi et al 2001) or early stages of inflammatory disease might also be overlooked (Jeandel et al 2016).…”

Objectives To determine whether the neurological examination correctly distinguishes between central and peripheral vestibular lesions in dogs. Materials and Methods Retrospective study on dogs with vestibular disease presenting to two referral clinics in Germany. Results Ninety‐three dogs were included; neurological examination suggested central vestibular disease in 62 and a peripheral lesion in 31. MRI diagnosis was central vestibular disease in 68 dogs and peripheral in 25. Of the 62 dogs with a lesion localisation diagnosed as central vestibular by neurological exam, 61 were correctly identified (98.4%). Twenty‐four of the 31 dogs diagnosed with a peripheral lesion by neurological exam had a consistent lesion on MRI (77.4%). Clinical Significance The neurological examination is efficient at identifying lesions in the central vestibular system but less so for peripheral lesions. Therefore it is prudent to recommend imaging in dogs that show signs of peripheral vestibular syndrome but do not rapidly respond to treatment.

Facial and vestibular neuropathy of unknown origin in 16 dogs

Abstract: Facial and vestibular neuropathy of unknown origin shares similarities with idiopathic facial paralysis. The prognosis for return of normal facial and vestibular function is guarded and there may be relapse after recovery.
