Is there any treatment for CRAO?
There are a number of therapies that has been used in the treatment of CRAO in the past. These include carbogen inhalation, acetazolamide infusion, ocular massage and paracentesis, as well as various vasodilators such as intravenous glyceryl trinitrate.
What does CRAO mean in medical terms?
When one of the vessels that carry blood to your eye’s retina gets blocked, it can cause you to lose your eyesight. This problem often happens suddenly and without any pain. This is called a central retinal artery occlusion (CRAO).
Is a CRAO a stroke?
Central retinal artery occlusion (CRAO) is a form of acute ischemic stroke that causes severe visual loss and is a harbinger of further cerebrovascular and cardiovascular events.
How is CRAO diagnosed?
A CRAO diagnosis is based on recognizing its clinical features from the patient history and ocular examination. CRAO presents as sudden nonpainful visual loss in one eye, with a Snellen VA of counting fingers or worse in 74% of patients. Ocular findings are based upon fundoscopy, fluorescein angiography, and OCT.
Is CRAO reversible?
Unfortunately, there is no clinically proven treatment for CRAO. Several therapies may be used including: Hyperventilation—inhaling carbogen, a mixture of 95% oxygen and 5% carbon dioxide, to attempt to dilate the retinal arteries and cause the clot to dislodge.
What causes lack of blood flow to eye?
An eye stroke, also known as retinal artery occlusion, is caused by a clot, or narrowing of the retina’s blood vessels. The retina’s blood flow is interrupted and, if left untreated, can result in permanent damage to the retina and loss of sight.
Why edema occurs in CRAO?
Cystoid macular edema arises due to the breakdown of the blood-retinal barrier causing accumulation of fluid within the retina, specifically between the inner nuclear and outer plexiform layers, resulting in a “flower petal” appearance [7, 8].
