Different types of eye infections and how to protect yourself

The most common type of infection that affects your eye is conjunctivitis. It is caused by an adenovirus (a kind of common cold virus).


Majority of the viruses, fungi, bacteria and parasites that invade a human body are also capable of attacking the outer and inner surface of your eye. Infectious eye diseases can be differentiated into two categories.

Initially, your eye doctor will focus on the specific part of your eye that is inflamed or infected.

Conjunctivitis, for instance, is an inflammation of the conjunctiva, the membrane of the inner corner and the inner eyelid of the surface of the eye. Other places where you can have inflammation include the eyelid (blepharitis), the liquid inside the eye (vitritis), the cornea (keratitis), the optic nerve (neuroretinitis), the retina and the blood vessels that feed it (chorioretinitis). These are just a few areas. The eyes are an extremely complex organ that has a number of important parts.

In second category, eye infections are classified according to what’s the reason for infection.

For example, an Ocular histoplasmosis syndrome is triggered by a fungus (the condition is called chorioretinitis). It normally attacks the blood supply of the retina, on the inner rear surface of your eye.

The most common type of infection that affects your eye is conjunctivitis. It is caused by an adenovirus (a kind of common cold virus). This kind of infectious conjunctivitis is sometimes termed as pinkeye and is very common among children. Viral conjunctivitis is contagious in nature as it can spread from the eye to hands, which then comes in contact with doorknobs and other surfaces used by people which causes the infection to spread.

Staphylococcus aureus is another bacteria that is a known cause of viral conjunctivitis. Bacterial infections are very common among children and tend to stay for a longer duration in cases of pinkeye.


Infectious conjunctivitis is the major reason behind pinkeye. The reasons that can cause infectious conjunctivitis are numerous and can be classified as viral, fungal and bacterial.

Pink eye, or conjunctivitis. Regular infectious conjunctivitis majorly has viral or bacterial origins. Infants can be infected with conjunctival eye infections (gonococcal and chlamydial conjunctivitis) during birth if their mother has a sexually transmitted disease.
