Ocular Stroke

by Dr. Sanjay Smith.

What are the symptoms of a stroke in the eye?

The major symptom is a sudden, painless loss or major decrease in vision of the eye.

What is a stroke of the eye?

The technical term is called retinal artery occlusion, or retinal vein occlusion of the eye.   This occurs when an artery or vein of the retina (the most posterior portion of the inner eye) is blocked.  Blood cannot supply the rest of the retina, causing death of tissue and loss of vision.

What are the causes of strokes?

As with strokes of the brain, high blood pressure, high cholesterol, high eye pressure, and hypercoagulation diseases (Lupus) can cause strokes in the eyes.

What can I do to prevent this condition?

To prevent retinal arterial or venous occlusions (strokes), make sure your blood pressure, diabetes, and cholesterol are under control.

If I know someone who has had a stroke, what should they do?

It is very important that they see an ophthalmologist.  They need to be followed to prevent possible glaucoma in the eye.  They also should have blood test to prevent a possible stroke of the other eye.

If you have had loss of vision, or know anyone that has had loss of vision, please see an ophthalmologist as soon as possible.

Ocular Allergy

by Dr. Sanjay Smith.

Allergy Season is Here

Can the eyes have allergies?  The majority of people who suffer from seasonal allergies also have signs and symptoms of ocular allergies or allergic conjunctivitis.

What are the symptoms of Ocular Allergies?  Itching, red, watery eyes are the major symptoms.

Are Ocular Allergies contagious? Ocular Allergies are Not contagious.  The eye may get as red as someone who has” pink eye”, but this is not caused by a virus.

Can allergies be year round?  Yes. The majority of ocular allergies occur during the early spring and late summer/early fall months due to pollen, but allergies can be year round due to animal dander allergy or pollution.  

What are the treatments for ocular allergy?  Your doctor may prescribe you artificial tears to sooth the eye and rinse away the allergens.  Your doctor may also prescribe ‘anti-itch’ eye drops, that inhibit the release of histamine (the agent which causes itching).

Are there home remedies to treat allergy?  Avoiding the allergy is the best treatment.  Washing your hands before touching your face can decrease direct exposure to the eyes.  Also, changing clothes immediately after entering your home can reduce the exposure to pollen that has fallen onto your clothes.  Also showering before bedtime can also reduce your exposure to the pollen that has fallen onto your skin.

Can Allergies cause blindness?   Almost never, but vigorous scratching can decrease vision temporarily, and may cause an abrasion of the cornea.

If you have or know someone who has Ocular Allergy, call your local ophthalmologist for an examination.
