How can you tell the difference between pink eye and allergies?

My eyes have been pink for three days straight. I'm allergic to a lot of things (pollens, foods, medications), but usually the pink goes away eventually. Antihistimines have no affect, and my eyes don't itch. It's been three days straight and I'm seeing the doctor today. I wondering if anyone else had any insights for me.

How can you tell the difference between pink eye and allergies?
I think it's allergies. With pink eye, it usually makes your eye filled with puss and very hard to open. Here's some info from wikipedia also. Good luck at the doctor's!





Conjunctivitis symptoms and signs are relatively non-specific. Even after biomicrosopy, laboratory tests are often necessary if proof of aetiology is needed.





Prominent itch and pale watery swelling (edema) of the conjunctiva or eyelids suggests allergy.





A purulent discharge strongly suggests bacterial cause, unless there is known exposure to toxins. Infection with Neisseria gonorrhoeae should be suspected if the discharge is particularly thick and copious.





A diffuse, less 'injected' conjunctivitis (looking pink rather than red) suggests a viral cause, especially if numerous follicles are present on the lower tarsal conjunctiva on biomicroscopy.





Scarring of the tarsal conjunctiva suggests trachoma, especially if seen in endemic areas, if the scarring is linear (von Arlt's line), or if there is also corneal vascularisation.





Clinical tests for lagophthalmos, dry eye (Schirmer test) and unstable tear film may help distinguish the various types of dry eye.





Other symptoms including pain, blurring of vision and photophobia should not be prominent in conjunctivitis. Fluctuating blurring is common, due to tearing and mucoid discharge. Mild photophobia is common. However, if any of these symptoms are prominent, it is important to exclude other diseases such as glaucoma, uveitis, keratitis and even meningitis or carotico-cavernous fistula.

Reply:When you have pink eye you get a lot of drainage from the infected eye. Maybe it's neither pink eye or allergies...go to a doctor. Your vision is too important to fool around with.
