Eye Infections: Causes, Types And Treatments

Bacterias and fungi are constantly attacking the human body, and this also means that these same infections are attacking both the interior and surface of the eye. The result is an infectious eye disease, which can be classified in two different ways. The first way eye care professionals classify an infectious eye disease is to determine which part of the eye is infected. The second way is to determine the cause of the eye infection. Once this has been determined, a treatment plan can be implemented.

Causes and Types

Eye Infections

Perhaps one of the most common eye infections is conjunctivitis, or pinkeye. This eye infection can be caused by a bacterial, fungal, or even viral infection, and bacterial conjunctivitis is most common in young children. The infection effects the inner corner of the eye and the inner eye lid causing it to become inflamed. The infection is spread most often by the transfer of bacteria from dirty hands or other surfaces that are frequently touched.

Other causes and types of eye infections include,

  • OHS, or ocular histoplasmosis syndrome is a fungal infection that occurs in the lungs and can eventually appear in the retina of the eye. The symptoms of this disease mimic those of macular degeneration and is the leading cause of blindness in young American adults.
  • Sexually transmitted diseases can also cause eye infections. Chlamydia, gonorrhea, and herpes can all be spread to the eye, most commonly from rubbing the eye area after touching an infected part of the body.
  • Shingles, which are highly contagious to those who have not yet had chickenpox, is a viral infection that tends to effect older adults. The viral infection is spread easily to the eyes, usually after first touching an infected sore.
  • Bacterial keratitis is a common cause of conjunctivitis. This infection is caused by the bacteria that is commonly found in mouths, noses, and on hands. It is usually spread to the eye by rubbing, and usually does not penetrate into the inner eye.


Luckily, most cases of conjunctivitis cure themselves in only a few days, but other eye infections require hypothyroidism and eyelash loss treatment.

Stubborn and repeat cases of conjunctivitis are usually given a general antibiotic to help kill the infection, while other infections may need a certain antibiotic. Anti viral medications are often used to treat herpes infections in the eye, along with infections caused by other sexually transmitted diseases. Unfortunately, the only way to treat an eye infection caused by histoplasma (OHS) is with laser cauterization. This procedure often needs to be performed several times before the fungal infection is gone. There is currently no known way to repair any damage to the eye by the infection.

Sometimes the best treatment for an eye infection is to prevent an eye infection from occurring. Carefully washing hands before touching the eye area can dramatically reduce the risk of contracting an eye infection. Other preventive steps can include refraining from sharing makeup, to not sharing a towel or a pillow.

Practicing safe sexual practices can also dramatically reduce a person’s risk for developing an eye infection. This also includes proper hand washing after sexual intercourse, and refraining from touching the eye area. Regular screenings for a sexual disease can also help to prevent any eye infections from forming.

An eye infection is not an inevitable occurrence, it can be easily prevented. Proper hygiene is one of the most important factors when trying to eyelash mites treatment or trying to avoid an eye infection. Most eye infections are bacterial and can be easily treated, but the health of the eye is too important to risk. Once the eye has been damaged, it can not be repaired or replaced, it is gone forever.
