Purpose:
To report a case of ocular ischemic syndrome in a diabetic patient.
Methods:
The patient's main complaint was an insidious unilateral decrease in visual acuity of the right eye. This diabetic 60-year-old patient presented numerous vascular risk factors.
Results:
Diagnosis was suspected from the fundus examination and was confirmed on ultrasonic carotid imaging combined with MR angiography showing a significant internal carotid artery stenosis.
Conclusion:
This case should remind clinicians to be cautious when dealing with any asymmetric ophthalmological exam. The diagnosis of ocular ischemic syndrome has to be suspected in case of unilateral retinal ischemia.
