For those who do not know, conjunctiva is a loose type of connective tissue. There is the bulbar conjunctiva which covers the surface of the eyeball and the palpebral conjunctiva which is actually the inner layer of the eyelid. Conjunctiva meets the cornea at the limbus and it is known for adhering to the sclera rather firmly. Conjunctiva is also responsible for containing the goblet cells and the accessory lacrimal glands. These organs are in charge of keeping the eyes lubricated in a proper manner. Conjunctivitis is one of the most common medical conditions which are associated with the eyes. This medical condition can be characterized as an inflammatory condition of the conjunctiva and in most cases it is usually referred to as pink eye. Conjunctiva is a mucous membrane so it is fairly normal to expect that a large number of different types of infectious agents may adhere to it, mess with the functioning of different mechanisms of defense and ultimately lead to symptoms such as photophobia, irritation, discharge and redness. Conjunctivitis may be triggered by a large number of different agents but the most common ones include allergic, chemical, chlamydial, toxic, parasitic, fungal, bacterial and vital agents. The most common types of conjunctivitis are triggered by viral agents, and they usually occur mostly in spring or late fall. Conjunctivitis may also be classified by the course of the disease or the age of occurrence. Acute conjunctivitis is a fairly common medical condition and it is caused by both viral and bacterial factors in equal proportions. Bacterial conjunctivitis usually occurs during winter or spring, while its viral counterpart occurs more during the hot months of summer. Most cases of conjunctivitis are self limited and are mostly benign, but in some cases they may evolve into much more severe medical conditions which tend to even be sight threatening.
Viral conjunctivitis is often associated with exposure history, minor levels of painful sensations and an acute onset. It is commonly accompanied by a watery discharge and pruritus, while in some cases photophobia and foreign body sensations may occur as well. Chlamydia and herpes simplex can be present in some cases and the same can be said for the follicular conjunctival change and preauricular adenopathy. In most cases, the condition is self limited for periods of time which are no longer than two weeks, but in some cases, several symptoms may be present for up to 6 weeks. The most common treatment methods include saline irrigation and prescription antibiotics.
