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

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

Ophthalmologist : Make sure you see an ophthalmologist for evaluation.

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. ...Read more

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. ...Read more

Can lorazepam or celexa cause eye irritation besides blurred vision?

Can lorazepam or celexa cause eye irritation besides blurred vision?

Eye irritation: I do not think either of those medicines could cause eye irritation. But what do you mean by that? Is the eye red, does it itch? This time of year, if both eyes are bothered, seasonal allergies would be a likely cause of this symptom. ...Read more
