In the majority of cases pink eye develops as a consequence of viral infection. Adenovirus is the leading infectious agent responsible for this type of conjunctivitis. Viral conjunctivitis is frequently reported in late fall and early spring.

Photophobia or increased sensitivity to light my also occur. Before the conjunctiva gets inflamed, a patient may experience 'cold like' symptoms such as sinus congestion and runny nose.

There are many bacteria capable of causing bacterial conjunctivitis. Staphylococci and Streptococci are only some bacterial strains reported to cause pink eye in humans.

This infection develops rapidly and soon after being contaminated, the affected eye gets inflamed. There is eye pain, swelling of both eyelids, itchy sensation and redness of the entire conjunctiva. Depending on the bacteria, there is also various amount of discharge of different color (yellow, green etc.). If present in large amounts, discharge may cause sticking of the eyelids during the night which simply cannot be opened in the morning. Under these circumstances one should apply a warm washcloth to the eyes and gently remove the discharge.

Bacterial conjunctivitis is treated with antibacterial ointments and tear drops or the combination of the two. Once prescribed with eye drops or eye ointment, patients are not supposed to share these because this may lead to further spread of the infection. Bacterial conjunctivitis can be additionally spread after sharing towels contaminates with the eye discharge.

To sum up, any inflammation of the conjunctive must be reported. A well experience ophthalmologist will confirmed or rule out viral or bacterial conjunctivitis and prescribe appropriate treatment. Do not try to treat the condition on your own, because this may cause serious complications.
