Abstract

Objective: Neuro-ophthalmological abnormalities (blindness, miosis, mydriasis, anisocoria, Horner’s syndrome, strabismus and nystagmus) appear frequently in dogs and cats admitted with neurological disease. This study reports the incidence of neuro-ophthalmological abnormalities in 99 dogs and 15 cats with neurological disease, along with correlation with the commonest final diagnoses. Methods: The study population consisted of dogs and cats admitted with neurologic signs and at least one neuroophthalmological sign. Inclusion criteria were history, clinical and neurological examination, neuroanatomic and aetiologic diagnosis. Descriptive statistics were used. Results: The most frequent presenting complaints were head tilt (22/99) and paresis/paralysis (22/99) in dogs and head tilt (3/15) and ataxia (3/15) in cats. The most common neuroophthalmological abnormalities were strabismus (55/99) in dogs and anisocoria (7/15) in cats. The localization of lesions was found to be multifocal (38/99), and focal, in the vestibular system (37/99) in dogs, whilst in cats it was solely multifocal (6/15). An aetiologic diagnosis was reached only in 48 dogs and 10 cats; the former were mainly diagnosed with distemper encephalitis (10/48) and congenital hydrocephalus (6/48) and the latter mostly with encephalitis (5/10). Statement: Neuro-ophthalmological abnormalities may be misinterpreted by concurrent extra-neural, ocular signs or stress reflex reactions that may hamper diagnosis. Consequently, neuro-ophthalmological examination and correlation with neurological signs is important for the neuroanatomic diagnosis, severity assessment and prognosis of the respected diseases. As shown, neuroophthalmological cases reached a 18.24% of the total neurologic case load admitted during a five-year period; therefore, represent a significant number of cases, which should not be ignored.
