235 EYES WIDE SHUT: A CASE OF BILATERAL PTOSIS FOLLOWING STROKE

Abstract

Abstract Background Bilateral ptosis is a rare manifestation of midbrain stroke. It has been reported in case studies only, with no data on incidence rate, and no published case report in Ireland to date. Methods This is a retrospective case study of a man admitted to an acute stroke unit following collapse and unresponsiveness. A review of his medical records and radiological database was conducted. A PUBMED database search was conducted to search for similar cases. Results We present the case of a man who had a witnessed collapse whilst farming and was brought to hospital and presented with a Glasgow Coma Scale of 3. Imaging showed a normal CT Brain. MRI revealed 2cm acute bilateral thalamic and midbrain infarction. Following a brief period in ICU he was transferred to the acute stroke unit for multidisciplinary care. Despite improvements in his medical status and communication efforts, his inability to open his eyes contributed to a persistently low GCS. Neurological assessment revealed bilateral ptosis, fixed dilated pupils and oculomotor paralysis. These symptoms had a profound impact on his stroke recovery, impeding assessments and interventions and engagement in all realms (swallow and communication; mobility and function, cognitive-perceptual) whilst also limiting opportunities for social interaction. Once staff became aware of the ophthalmoplegia, strategies were implemented to optimise his participation and provide opportunities of recovery. Three months post stroke, he began to experience some return of unilateral eye-opening and bilateral horizontal movements (with diplopia) which greatly improved his overall performance. He was then transferred to the rehabilitation unit where he continues to progress. Conclusion Bilateral ptosis post stroke is rare and has a debilitating effect on participation in all aspects of living and interaction with the environment. This presentation has previously been described as “reverse locked-in-syndrome” which accurately represents its impact.
