Abstract Details


Ocular motor apraxia (OMA), is a rare entity described by Cogan in 1952. (1) Before his report, many of these patients were referred from pediatricians in their early life with a presumed diagnosis of cortical blindness. (2) These patients have absent or defective horizontal voluntary saccade movements, while vertical saccade movements were normal. Furthermore, they had intact random horizontal movements, and intact both vertical and horizontal pursuits. (1) the purpose of this presentation is to review and refresh memories of the ophthalmologist regarding this rare entity

This is a formal video presentation of five patients with the diagnosis Of childhood blindness. these patients were proven after full ocular and orthoptic assessment and investigations to have normal vision confirmed by their follow up and normal visual development later in life, one patient was also found to have ataxia and may fall in to the category of ataxia oculomotor apraxia group.


Oculomotor apraxia can be congenital or acquired. It is idiopathic in most of the cases, with some exceptional familial reports. (4) It may also be an isolated condition, but can be associated with structural brain abnormalities (e.g. cerebellar hypoplasia, agenesis of the corpus callosum), neurodegenerative disorders (e.g. ataxia telangiectasia, Gaucher’s disease), perinatal comorbidities (e.g. hypoxia, cerebral palsy, hydrocephalus), or acquired diseases (e.g. herpes encephalitis, posterior fossa tumor, or ischaemia). (3) In this presentation we are describing five cases of oculomotor apraxia who presented to different healthcare institutes in Riyadh, Saudi Arabia during the period 2014 /2017


Oculomotor apraxia is a rare entity that is not well understood, patients with this diagnosed are hard to evaluate especially if present early in life, and can be wrongly diagnose with blindness, regular ophthalmologist may be un-aware of this entity and misdiagnosis will enforce parents stress, awareness of this disease among the ophthalmologist is recommended
