What diseases can cause ocular ischemic syndrome?
Those with ocular ischemic syndrome may also present with a history of other systemic diseases including arterial hypertension, diabetes mellitus, coronary artery disease, previous stroke, and hemodialysis. The condition presents with visual loss secondary to hypoperfusion of the eye structures.
How old is too old to have ocular ischemic syndrome?
Those with ocular ischemic syndrome are typically between the ages of 50 and 80 (patients over 65); twice as many men as women are affected. More than 90% of those presenting with the condition have vision loss. Patients may report a dull, radiating ache over the eye and eyebrow. Those with ocular ischemic syndrome may also present with a history of other systemic diseases including arterial hypertension, diabetes mellitus, coronary artery disease, previous stroke, and hemodialysis.
What happens if you have carotid occlusive disease?
If carotid occlusive disease results in ophthalmic artery occlusion, general ocular ischemia may result in retinal neovascularization, rubeosis iridis, cells and flare, iris necrosis, and cataract. The condition leads to neovascularization in various eye tissues due to the ischemia.
What is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye?
Ocular ischemic syndrome. Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye.
What is ophthalmic artery occlusion?
Severe ophthalmic artery occlusion, due to thromboembolism. Surgical interruption of anterior ciliary blood vessels supplying the eye, particularly during extensive strabismus surgery on 3 or more rectus muscles, leading to an anterior segment ischemic syndrome.
Is argon laser effective for ocular ischemic syndrome?
At a later stage, pan-retinal photocoagulation (PRP) with an argon laser appears effective in reducing the neovascular components and their sequelae. The visual prognosis for ocular ischemic syndrome varies from usually poor to fair, depending on speed and effectiveness of the intervention.
Pathophysiology
The most common etiology is severe atherosclerosis-induced carotid stenosis resulting in greater than 90% occlusion of the ipsilateral carotid artery. 2 Studies have shown that at 90% carotid occlusion, perfusion pressure of the ipsilateral central retinal artery is reduced by half.
Clinical Features
Symptoms. The most common symptom of OIS (in 67%-90% of cases) is gradual vision loss that develops over weeks to months. 2 It is important to note that around 30% of eyes with OIS have visual acuity between 20/20 and 20/50 at presentation.
Diagnosis
Carotid imaging. Carotid imaging is the most important modality to support a diagnosis of OIS. Carotid duplex ultrasound (DUS) is the most commonly performed initial diagnostic test, as it is accurate, noninvasive, low cost, and widely available.
Angiographic Findings
Staining of the major retinal vessels (mostly arteries) and their branches at the late phase
Management
Surgical management of carotid artery disease. The definitive treatment for OIS due to stenosis is carotid artery reperfusion surgery by means of carotid artery endarterectomy (CEA) or stenting.
Conclusion
The ophthalmologist may be the first person to recognize carotid artery insufficiency because the signs and symptoms of OIS may manifest before other systemic signs.

What causes ocular ischemic syndrome?
The most common cause is atherosclerosis of the carotid artery, although inflammatory conditions such as giant cell arteritis occasionally can be responsible. Ophthalmic artery obstruction accounts for fewer than 5 percent of cases.#N#It has been shown that blood flow to the eye is relatively unaffected until carotid obstruction exceeds 70 percent. When the obstruction reaches 90 percent—the minimum typically needed to cause the ocular ischemic syndrome —the perfusion pressure within the central retinal artery decreases by 50 percent. Approximately 50 percent of people with the ocular ischemic syndrome have total ipsilateral carotid artery obstruction, and about 10 percent have bilateral total carotid artery obstruction.
What percentage of people have ischemic heart disease?
Fifty percent of patients have ischemic heart disease, about 25 percent have had a previous stroke and about 20 percent have had peripheral arterial disease requiring surgery. The five-year mortality is approximately 40 percent, with cardiac disease being the most common cause of death. 3.
What is the name of the ocular disorder that Kearns and Hollenhorst described

What percentage of eyes are affected by panretinal laser photocoagulation?
When iris neovascularization is present and the anterior chamber angle is open, panretinal laser photocoagulation should be considered, as it causes regression of the iris and angle vessels in about 35 percent of eyes.
What is the differential diagnosis of diabetic retinopathy?
The differential diagnosis includes diabetic retinopathy, nonischemic central retinal vein occlusion, parafoveal telangiectasis and radiation retinopathy. Light digital pressure on the globe through the eyelid often produces arterial pulsations in eyes with ocular ischemic syndrome, while this is not the case with the other diseases in the differential diagnosis.
What is anterior chamber flare?
Anterior chamber flare is present in most eyes with iris neovascularization, and there is a mild (1+ to 2+ on a 4+ scale) anterior chamber cellular response in about 20 percent of affected eyes. Keratic precipitates are generally absent.
Is IOP normal with neovascularization?
Despite the fact that the anterior chamber angle is synechially closed in many eyes with iris neovascularization, IOP may be normal, or even decreased, due to poor ciliary body perfusion. When iris neovascularization is present, 90 percent of eyes deteriorate to counting fingers vision or less within a year.
Introduction
Ocular ischemic syndrome (OIS) is a rare, but vision-threatening condition associated with severe carotid artery occlusive disease (stenosis or occlusion) leading to ocular hypoperfusion. Principal symptoms include visual loss, transient visual loss, and ischemic ocular pain. OIS commonly occurs in the elderly with me…
Epidemiology and Pathogenesis
- Ocular ischemic syndrome occurs at a mean age of 65 years, is rare before 50, has no racial predilection. Men are affected twice as often as women likely due to the higher incidence of atherosclerotic disease in males. Bilateral involvement may occur in up to 22% of cases. The degree of stenosis, the presence or absence of collateral vessels, chronicity of carotid artery dis…
Fluorescein Angiogram
- Fluorescein angiography can help to establish the diagnosis of OIS. Particularly characteristic findings are delayed choroidal filling time (most specific angiographic sign) and prolonged arteriovenous (AV) transit time (most sensitive angiographic sign). Overall, a prolonged arteriovenous transit time is seen in 95% of cases, retinal vascular staining in 85%, and delayed …
Imaging Methods For The Evaluation of Carotid Occlusive Disease
- Carotid Duplex Ultrasound
Duplex carotid ultrasonography is the most commonly used non-invasive test and combines B-mode ultrasound and Doppler ultrasound, providing both anatomical imaging of the vessel and flow velocity information. The parameters used to classify severity of stenosis include peak syst… - Color Doppler Imaging of Retrobulbar Vessels
Color Doppler imaging of retrobulbar vessels is a useful adjunct to conventional duplex ultrasound for carotid artery examination. Distal to a hemodynamic significant stenosis, the blood pressure is decreased and the Doppler effect is dampened, causing diminished blood flow velocity. Therefo…
Symptoms
- Overview
As OIS is an ocular manifestation of systemic disease, patients with OIS may initially present with constitutional rather than ocular symptoms. In a review of 42 patients with OIS, only 6 reported developing ocular symptoms as their initial complaint. Additionally, patients may overlook their … - Visual Loss
Decrease in visual acuity in OIS may be severe, with acute or subacute presentation. In a series of 43 patients, at initial presentation, 35% of eyes had a VA of 20/20 to 20/40 and in 35% had vision of counting fingers or worse. Similarly, in 52 patients studied by Sivalingam et al, 43% of the affe…
Signs

Systemic Associations
- Atherosclerosis of the carotid vascular system is the major cause of OIS and may be its initial manifestation. Atherosclerotic plaques are usually located at the site of carotid bifurcation or at the proximal segment of the ICA. However, an intracranial carotid artery stenosis may also lead to OIS. Generally, ≥ 90% stenosis of the ipsilateral carotid arterial system is present in eyes with OI…
Differential Diagnosis
- Diabetic retinopathy and Central Retinal Vein Occlusion (CRVO) are the two most likely conditions to be confused with OIS. A basic differentiating feature is the low retinal artery pressure in eyes with OIS. Table 2lists the clinical and angiographic signs that help to differentiate these three. The differential diagnosis of OIS should also include the hyperviscosity syndromes. Fundus manifest…
Management of Ocular Ischemic Syndrome
- The management of OIS involves a multidisciplinary approach. The aim is threefold, firstly to treat the ocular complications and prevent further damage, secondly to investigate and treat the associated vascular risk factors, and thirdly to perform vascular surgery whenever indicated.
Surgical Treatment
- Carotid Artery Endarterectomy
The landmark North American Symptomatic Carotid Endarterectomy (NASCET) trial demonstrated the superiority of carotid endarterectomy (CEA) and aspirin therapy in preventing stroke compared with aspirin therapy alone for both symptomatic and asymptomatic carotid art… - Carotid Artery Stenting
Endovascular carotid artery stenting (CAS) is a treatment alternative in patients who need CEA. CAS has been used for patients who are considered to be at high-risk for complications after CEA including those with anatomic conditions rendering surgery technically difficult, such as previou…
