To reduce the risk associated with keeping our eyes open throughout the day evolution has provided a useful protective layer, the Conjunctiva. On top of its role as a protective barrier the conjunctiva is also important in the production of tears and the maintenance of homeostasis in the eyes.
In this module we'll first explore the healthy conjunctiva and its various layers and glands. Next we will turn to conjunctivitis which is the proper medical term for that nearly ubiquitous illness "pink eye." There are many different types of conjunctivitis so we will take special care to distinguish between the causes, appearance, and treatment of each.
Without our conjunctiva we'd be at constant risk of damaging our eyes during the simple act of looking at things. Let's take a deeper look at how this defender keeps our eyes in working condition.
