Dx - optic nerve hyperemia. Blurred vision in left eye for more than a year. Possible causes? Can be from use of Zaditor (ketotifen) for allergies?

Dx - optic nerve hyperemia. Blurred vision in left eye for more than a year. Possible causes? Can be from use of Zaditor (ketotifen) for allergies?

Ophthalmologist: Make sure you see an ophthalmologist for evaluation. You may have congenital blurring of optic disc, disc drusen, hypoplasia, but with the blurred vision, I'd be worried about something different. A year-long history without worsening is not typical of inflammatory optic neuritis. Compression of nerve by tumor? Zaditor™ is not the cause. See an ophthalmologist.

What would cause eye twitching, and blurry vision in one eye only. Happens daily although its worse during allergy season.

What would cause eye twitching, and blurry vision in one eye only. Happens daily although its worse during allergy season.

Stress: Eye twitching and blurry vision are 2 different symptoms that are usually unrelated. Most common cause of twitchy eyes are stress. If you also get clamps in your legs then your parathyroid and calcium should be checked. Blurry vision needs a complete eye exam.

I suffer immensely from allergies. Itchy eyes. Light sensitivity, blurred vision and rapid heart beat. I I don't know what I'm allergic to?

I suffer immensely from allergies. Itchy eyes. Light sensitivity, blurred vision and rapid heart beat. I I don't know what I'm allergic to?

See your doctor: Itchy eyes are a symptom of allergy, and if there are a lot of secretions, this can lead to temporary blurring of vision. But neither light sensitivity nor rapid heart beat are symptoms of an allergic reaction (rapid heart beat only with a severe, life-threatening reaction). You need to see your doctor to get all these symptoms sorted out.

After eating peanut butter, I have burning eyes, throat/eye swelling, low blood pressure, blurred vision. I have eaten it since a child so no allergy

After eating peanut butter, I have burning eyes, throat/eye swelling, low blood pressure, blurred vision. I have eaten it since a child so no allergy

Anaphylaxis?: It appeared that you had suffered shock from the peanut butter. Although most food allergies developed in childhood, they can also occur in adults. Before you touch peanuts again, be sure to get tested by an allergist. In the meanwhile, you need to carry an epineprhine autoinjector (preferably 2) with you until this issue has been clarified.

Doc says I have allergy and dry eye. Constant blurry vision and ghosting. Vision does not improve with drops. With glasses still 20/20. What's wrong?

Doc says I have allergy and dry eye. Constant blurry vision and ghosting. Vision does not improve with drops. With glasses still 20/20. What's wrong?

See eye doctor: Allergic eyes only affect vision occasionally but dry eyes often do. Perhaps your vision is blurred because you need something more than just artificial tear but then I don't understand how you could have 20/20 vision if the vision were indeed blurred until this degree of visual acuity is only present intermittently. Please clarify.

I've had a watery eye, pressure, and blurry vision for 6 mo. My eyedoctor and ENT have no answers. I have chronic sinusitis/allergies. Please help.

I've had a watery eye, pressure, and blurry vision for 6 mo. My eyedoctor and ENT have no answers. I have chronic sinusitis/allergies. Please help.

See an allergist: Your symptoms are consistent with allergic rhinoconjunctivitis / rhinosinusitis or inflammation of your nose, eyes and sinuses due to allergy especially during this season when lots of trees are pollinated. This is a common problem in the us. When medications does not work, you should see an allergist to be evaluated and treated. We are specialized in diagnosing and treating these conditions.

Absolutely: A hyphema is blood in the aqueous fluid in the front of the eye, and can range from minor to very severe.

Medrol: does it cause blurred vision?

Medrol: does it cause blurred vision?

Usually not: Medrol (methylprednisolone) is commonly given in a short term allocation ('dose pack') which will not disturb the vision. If you are taking it chronically, visual blur can occur as the dose increases or decreases but will not be affected after two months of steady (same) dose. Discuss this with the doctor who prescribed the Medrol (methylprednisolone) if you are having some blur.
