My name's Dr. Alan Watson. I'm an ophthalmologist, in St. Joseph, Missouri, and we're here today to talk about eye problems. It depends on what's causing the eye to be red. The white of the eye can become red or injected from allergy. That's typically the cause in the spring and the fall when a lot of the trees are pollinating in the spring, or in the fall it's generally goldenrod and ragweed, and they elaborate pollen which flies through the air, contacts the eye. The eye is a encounters that offending pollen, and in in allergic individuals will mount an immune response; trying to clear that irritant from the eye which causes tearing, redness of the eye. The redness is generally the eye eye's attempt to bring in more blood cells to deal with they perceive the threat or the irritant to be. And so, to get rid of a redness of the eye from allergy, typically, topical antihistamines are used such as Patanol. There's antihistamines that also, there's a a mast cell stabilizer that prevents the mast cells where the histamine is stored, and it it stabilizes that molecule so that the mass cell does not break up and release the histamines in the first place. And drugs that are mast cell stabilizers are like Alamast. Patanol also has a mass cell stabilization feature. Some red eye may just be from dry eye and that's treated with a ocular lubricant. Some red eyes are just from an eye infection, and that's treated with a topical antibiotic for bacterial infections of the lining of the eye or conjunctivitis. This has been Dr. Alan Watson, Ophthalmologist, at St. Joseph, Missouri, discussing different eye problems, and the treatment of different eye problems with you.
