“…7,9,10,15 Carotid artery endarterectomy in OIS leads to an increase of blood flow and improves clinical findings and symptoms after normalization of IOP. 5,[16][17][18][19][20] However, the visual prognosis of these patients remains poor. This is likely due to having endured intraocular ischemia over prolonged periods of time (days), as well as the possible secondary complications from frequent comorbidities such as diabetes and hypertension.…”

Severe carotid stenosis may be associated with uncommon clinical symptoms. We report a case of ocular ischemic syndrome and subsequent rubeosis iridis due to a high-grade carotid stenosis. The patient recovered visual acuity and his normal iris coloring after carotid endarterectomy. Rubeosis iridis may be the only clinical sign associated with severe carotid stenosis, making it mandatory to rule out the presence of carotid narrowing when it is detected. Establishing an early diagnosis is essential to improve quality of life, prognosis, and patients' outcome.

“…Although unilateral carotid artery occlusion is the most common finding in patients with OIS, there have been instances in which bilateral common carotid artery occlusion has been responsible for the onset of OIS [20,21]. Stenotic involvement of intracranial branches of the carotid artery is an extremely rare cause of OIS [22]. Recent advances in stenting and angioplasty have made stenting in intracranial lesions possible [22].…”

“…In cases of intracranial carotid stenosis, early diagnosis and prompt treatment of the affected areas are critical for preserving visual function and reducing risk of cerebral vascular events in patients with OIS [22]. Carotid endarterectomy is a commonly used method to remove stenotic areas of the carotid artery as long as the obstruction is less than 99% [19,23].…”

“…The diagnosis thus relies on the evaluation of a spectrum of symptoms, ophthalmoscopic, angiographic and paraclinical findings (Marx et al. ; Kofoed et al. ), which in our clinical practice includes ocular pneumoplethysmography (OPG) to assess ocular systolic perfusion pressure (Gee ) and motion‐contrast fundus photography to assess macular perfusion velocities (Izhaky et al.…”

Purpose: To assess retinal perfusion in eyes with unilateral ocular ischaemic syndrome (OIS) and to compare with control subjects. Methods: Retrospective case series. Linear blood flow velocities in macular vessels were estimated using motion-contrast fundus photography in eight patients with unilateral OIS (eight OIS eyes, seven fellow eyes) and 12 control subjects. The diagnosis of OIS was supported by carotid artery Doppler ultrasonography and pneumoplethysmographic measurement of ocular systolic perfusion pressure. Results: Macular arterial blood flow velocity (median, range) was 1.8 (1.4-2.7) mm/s in OIS eyes, 4.0 (2.9-5.3) mm/s in fellow eyes (p = 0.016) and 3.8 (2.3-5.1) mm/s in control eyes (p = 0.0004 and p = 0.67 versus OIS and fellow eyes, respectively). Macular venous blood flow velocity was 1.5 (1.0-2.1) mm/s in OIS eyes, 2.6 (2.0-2.9) mm/s in fellow eyes (p = 0.016) and 2.7 (1.8-3.5) mm/s in control eyes (p = 0.0007 and p = 0.64). Arterial velocities were below or equal to the lowest value observed in control subjects (≤2.3 mm/s) in seven of eight eyes with OIS. Visual acuity 0.7 or worse was found in two OIS eyes with arterial velocities below 1.7 mm/s and venous velocities below 1.3 mm/s and together with neovascular glaucoma or polycythemia vera (one eye each). Conclusion: Motion-contrast imaging revealed markedly reduced macular perfusion velocities in OIS eyes compared with unaffected fellow eyes and healthy control eyes. The method appears to provide a clinically meaningful quantitative measure of macular hypoperfusion.
