What is eye occlusion therapy?
What is occlusion therapy? Occlusion therapy, also called patching, occlusion or penalisation it is a treatment for amblyopia (reduced vision) known sometimes as lazy eye. It is not a treatment for squint/strabismus (an eye which turns) but may be used in children who have squints which are causing amblyopia.
What does occlusion in the eye mean?
Central retinal artery occlusion is the blockage of blood to the retina of one eye. It usually causes sudden loss of eyesight in one eye. You are higher risk if you are older or have high blood pressure, glaucoma, or diabetes.
Can retinal occlusion be cured?
Because the blocked veins cannot be unblocked, there is no cure for CRVO. Many people regain some vision even without treatment. However, even if vision does return, it rarely returns to normal.
How is occlusion treated?
For occlusions caused by blood clots, initial treatment might focus on dissolving the clot using medications. The doctors at St. Joseph's Heart & Vascular Institute may prescribe blood thinning medications to prevent future clots. Blood thinning medications also can help prevent occlusions in people at risk.

Laser treatment to prevent the growth of new, abnormal blood vessels that leads to glaucoma.
What causes an ocular occlusion?
Symptoms and Causes Retinal vein occlusion happens when a blood clot blocks the vein. Sometimes it happens because the veins of the eye are too narrow. It is more likely to occur in people with diabetes, and possibly high blood pressure, high cholesterol levels, or other health problems that affect blood flow.
Can you recover from retinal artery occlusion?
Unfortunately, the retina is very sensitive to ischemia and animal models have demonstrated irreparable damage occurs after 105 minutes of occlusion. Thus, the vision loss is often permanent with only mild visual recovery.
How can I increase blood flow to my eyes?
Exercise regularly The eyes need oxygen to stay healthy and comfortable. Growing scientific evidence suggests that aerobic exercise can increase crucial oxygen supplies to the optic nerve and lower pressure in the eye.
Can occlusion be reversed?
Since retinal vein occlusion cannot be reversed, treatment focuses on protecting your remaining vision. Action and advice to prevent further attacks can also be taken. Treatments include eye massages, glaucoma medication, injections, laser therapy and laser surgery.
How long does retinal vein occlusion last?
New research shows that a treatment for retinal vein occlusion yields long-lasting vision gains, with visual acuity remaining significantly above baseline at five years. However, many patients require ongoing treatment.
What causes lack of blood flow to the 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.
Is retinal vein occlusion permanent?

How do you know if you have a retinal vein occlusion?
Symptoms of a retinal vein occlusion can include: Pain in the eye from increased eye pressure brought about by secondary glaucoma. Blurred vision. Loss of side vision. Visual distortions. Symptoms that worsen in hours or days.
What causes blurry vision in the central vision?
Often, the blockage is associated with swelling of the retina in the central, or “macular” region (macular edema), which can cause blurring of the central vision .
What happens if your eye has only one vein?
The eye has only one vein with multiple branches, and when that vein or one of the branches is blocked , blood flow backs up and stagnates. Without regular blood flow, the cells in the retina may start to die. A retinal vein occlusion will impair sight in the affected eye and can eventually cause permanent damage.
What causes blurry vision?
Eye Stroke. Retinal Vein Occlusion. Glaucoma Treatment. Your retina is a thin layer of tissue that lines the back of your eyeball. It turns light into signals to the brain, which interprets them as sight. When a vein in the retina becomes blocked, it’s called retinal vein occlusion. This can give you blurry vision or even sudden permanent blindness ...
What is the test for retinal blockage?
They'll put drops in your eyes to open up your pupils. They’ll use a tool called an ophthalmoscope to check your retina for signs of blockage or bleeding. Your doctor may also order a test called a fluorescein angiography.

Most people’s eyesight will get better after a few months. But some may not see any improvements. Prevention. Usually, an underlying medical condition brings on a retinal vein occlusion. So it’s important to keep your blood pressure, cholesterol, and blood sugar under control.
Can a doctor see if you have a vein occlusion?
You may get drops to dilate your pupils and then a machine scans your eyes with rays of light to make a detailed image of your retina. There’s no cure for retinal vein occlusion.
Can a blood clot cause bleeding in the eye?
That raises pressure inside your eye, which can cause bleeding, swelling, and fluid leaks. Retinal vein occlusions can harm your eye in minutes. Usually, a blood clot blocks the vein. Sometimes, a nearby artery can be a problem. In the retina, arteries and veins cross over each other.

What causes blurred vision and loss of vision?
Blood and fluid leaking into the macula cause swelling, a condition called macular edema, which causes blurring and/or loss of vision. Neovascularization: RVO can cause the retina to develop new, abnormal blood vessels, a condition called neovascularization.
Why is blood flow blocked in the retina?
When the flow of blood from the retina is blocked, it is often because a blot clot is blocking the retinal vein. This condition is called retinal vein occlusion (RVO). Nerve cells need a constant supply of blood to deliver oxygen and nutrients. Blood vessels provide this supply.
What happens when a retinal vein is blocked?
When a retinal vein is blocked, it cannot drain blood from the retina. This leads to hemorrhages (bleeding) and leakage of fluid from the blocked blood vessels.

How does oxygen help the retina?
Carbon dioxide-oxygen. You breathe in a mixture of carbon dioxide and oxygen to increase blood flow to the retina. It also widens the arteries. Paracentesis. A specialist uses a small needle to remove a few drops of fluid from the front of your eye. This reduces pressure, which may increase blood flow in the retina.
Why is my vision blurry?

Symptoms
The most common symptom of branch retinal vein occlusion (BRVO) is vision loss or blurry vision in part or all of one eye. It can happen suddenly or become worse over several hours or days. Sometimes, you can lose all vision suddenly.
Who is at risk for BRVO?
Branch retinal vein occlusion (BRVO) usually happens in people who are aged 50 and older.
Diagnosis
Your ophthalmologist will widen (dilate) your pupils with eye drops and check your retina.
Treatment
With branch retinal vein occlusion (BRVO), vision usually worsens due to swelling of the macula. The main goal of treatment is to dry up the retina. In most cases, medication or laser help reduce fluid and swelling.
