Aims: To emphasize that ocular ischemic syndrome (OIS) is a rare but threatening condition. It is a consequence of occlusion or dissection of internal carotid artery (ICA).
Methods: A 66-year-old caucasian male presented in the emergency room with painful vision loss in his right eye and mild neurological symptoms. He was diagnosed ocular ischemic syndrome (OIS) in ICA and ophthalmic artery occlusion due to right ICA dissection.
Conclusions: It is very important to know and be able to recognise OIS as it may often be misdiagnosed or treated as a different entity. Patients with ICA occlusion and OIS must be treated as soon as possible by a stroke unit team to resolve ICA occlusion/dissection and by the ophthalmologist to prevent further ocular related complications.
