Ocular ischaemic syndrome (OIS) is a relatively uncommon condition. Simultaneous bilateral involvement is even less common and has been reported in only 22% of all cases of OIS. It has variable clinical presentations, of which visual loss and ocular pain are the most common. It is believed to occur when there is a 90% or greater carotid artery obstruction. This syndrome is often associated with a number of systemic diseases including diabetes mellitus, hypertension, coronary artery disease, and cerebrovascular disease. Only occasionally has it been described as a complication of rhinocerebral mucormycosis. We report an unusual case of bilateral OIS secondary to bilateral internal carotid artery thrombosis as a complication of invasive rhinocerebral mucormycosis. In addition, a review of clinical presentation, diagnostic work-up and treatment options for OIS is provided.

Ocular ischemic syndrome, also known as hypoperfusion/ hypotensive retinopathy or as ischemic oculopathy is a rare ocular disease determined by chronic arterial hypoperfusion through central retinal artery, posterior and anterior ciliary arteries. It is bilateral in 20% of the cases. Most often it appears due to severe occlusion of the carotid arteries (ICA, MCA>ECA), described in 1963 by Kearns and Hollenhorst. Occasionally it can be determined by the obstruction of ophtalmic artery or some arterities (Takayasu, giant cell arteritis). The risk factors are: age between 50-80 years, males (M:F = 2:1), arterial hypertension, diabetes, coronary diseases (5% of the cases develop ocular ischemic syndrome), vascular stroke, hemodialysis. The case we present is of an 63 years old man known with primary arterial hypertension, hypercholesterolemia, diabetes type 2 non insulin dependent and diagnosticated with ischemic cerebral stroke and bilateral obstruction of internal carotid arteries in march 2010, who is presenting for visual impairment in both eyes. The imaging investigations show important carotid occlusion and at the ophthalmologic evaluation there are ocular hypertension and rubeosis iridis at the right eye, optic atrophy at both eyes (complete in the right eye and partial in the left eye), with superior altitudinal visual field defect in left eye. The following diagnosis was established: Chronic ocular ischemic syndrome in both eyes with Neovascular glaucoma at the right eye, Anterior ischemic optic neuropathy at the left eye and laser panphotocoagulation at the right eye was started.

Ocular ischaemic syndrome is a progressive and serious vision-threatening condition that is usually associated with carotid artery disease, and poor effective therapeutic options are available. In the present case, a 65-year-old woman was submitted to embolisation of spontaneous carotid-cavernous fistula with complete resolution of initial ophthalmoplaegia and ocular hypertension. Later, ocular ischaemia was detected. Cerebral angiography showed delayed choroidal flush and the patient was admitted for hypervolaemic hypertension therapy and medicated with nimodipine. The ischaemia was reversed and visual function improved.
