Hello! [I’m] Dr Croley and welcome to Case of the Day. Today we’re gonna talk about a case that came in, which is a pretty common problem actually. And we’re gonna discuss what’s commonly known as pink eye or medically called conjunctivitis. So what is pink eye or conjunctivitis? So basically, [it] is an infection of the outer coating of your eye.
That is there’s an outer coating that covers over the white part of your eye that contains the blood vessels. So this white part has all these blood vessels in it and is called the conjunctiva. The white part of your eye is called the sclera. And the coating that goes over the outside of that is called the conjunctiva which has the blood vessels. So the outside coating is infected. And it is very common and can be thoroughly contagious though it’s typically not as contagious as most cases, let’s say a cold because you’re not coughing things into the air with your conjunctivitis obviously.
There are a couple of causes for conjunctivitis. The most common causes are virus typically even what’s called an adenovirus. And so the eye gets red, the blood vessels on the surface of the eye get engorged or red when it becomes infected. Your eye itches; you may have discharge; your eye may water. Usually your vision is not affected too much with conjunctivitis because the cornea, the clear part, is not affected with just plain pink eye or conjunctivitis, so your vision is usually not affected other than if your eye is watering a lot, then that watering will blur your vision ‘cause you don’t have a normal tear film across your cornea. And typically this is a self-limited disease really, just like a common cold is, but a lot of people are uncomfortable and so we do commonly treat this with antibiotic eye drops.
Sometimes with a combination cortisone and an antibiotic eye drop ‘cause the cortisone calms the eye down and makes it more comfortable and this helps especially in people who have a viral conjunctivitis and cuts down on the itching so their eyes are more comfortable and not as red while they have this infection going on. It does not shorten the process necessarily because if it is a virus, obviously an antibiotic is not gonna work. We try not to use too many antibiotics because, which you may have heard through TV and news releases that, if you keep using antibiotics when there’s not even a bacteria there what bacteria are lying around and not really causing any infection get resistant to the antibiotics. So you wanna be able to careful about of use of those.
And so typically if someone has a more purulent discharge, and if the discharge is more cloudy or milky, or yellowish or greenish discharge, then that typically more is a bacteria-caused conjunctivitis. Someone who has a more watery discharge typically has a viral conjunctivitis. So then if you get treated typically you’re on an eye drop four times a day unless there’s something really unusual and pretty quickly the conjunctivitis is resolved. You do need to be careful about sanitation so it is: wash cloths, bath towels – those kinda things you wanna keep away from your family members or anyone else. You don’t wanna get everybody else with the pink eye as well in your house. And so you need to be careful about that and wash your hands and keep your hands other than when you put the drops in your eyes away from your eye and when you do use the medicine, obviously, you want to wash your hands after you put the drop in. And then gently take a Kleenex, dab your eye off and then throw that Kleenex away.
So if you have any questions about what we discussed about pink eye which is a very common eye infection then you always try to contact us through the website. If not may God bless you with healthy eyes and great vision.
