Eye infections Treatment, Drugs, Causes, Symptoms, and Diagnosis

There are two common types of eye infections, conjunctivitis (also known as pink eye) and styes.  Eye infections can affect one or both eyes and can invade part of the eyeball or the adjacent area including the clear front surface of the eye (cornea) and the thin, moist membrane of the outer eye and inner eyelids (conjunctiva).

Eye infections Symptoms

The symptoms of an eye infection will vary based on the cause and type of infection. Again, the symptoms may range from severe to worse depending on the stage of infection. The most common symptoms of eye infections include the following.

  • Redness
  • Itching
  • Discharge
  • Pain
  • Reduced eyesight
  • Inflammation of the eyelid
  • Scarring of the inner eyelid
  • Pain in the affected eye
  • Sensitivity to light
  • Swelling around the eyes
  • Dry eyes
  • Swollen eyes
  • Dry eyes


Eye infections Causes

Eye infections are caused by bacteria, viruses or fungi. The most prevalent viral, fungal and bacterial causes of eye infections include:

  • Conjunctivitis: These are caused by viruses or bacteria. However, infants can acquire conjunctivitis during birth especially if the mother has a sexually transmitted disease.
  • Stye: Characterized by a bump on the eyelid, stye occurs when a bacteria from the skin gets into the hair follicle of an eyelash
  • Other viral eye infections include ocular herpes that occurs when your eye becomes exposed to the Herpes simplex virus
  • Endophthalmitis: a rare type of eye infection can be caused by mold that penetrates into the eye’s interior. Endophthalmitis is common in tropical regions.


Eye infections Diagnosis

Any time an eye infection is suspected, you should visit the doctor for an eye exam and proper eye infection diagnosis. Do not attempt to self-diagnose your condition as that may delay effective treatment not to mention the possibility of damaging the eye. In case you are wearing contact lenses, you should only wear your eyeglasses until you have visited the doctor for a diagnosis. Once at the hospital or clinic, your doctor will:

  • Start by determining the type of infection so as to prescribe the correct treatment.
  • Take a fluid sample from the affected eye to help identify the type of infection
  • Recommend the type of treatment based on the results of the physical examination


Eye infections Treatment

Treating eye infections involves dealing with the underlying cause. The most common bacterial infections clear up within days, particularly when prescriptions such as eye drops ointments are used early enough. Most viral eye infections go away on their own but for severe cases, an antiviral eye drop may be prescribed. Depending on the underlying cause and severity of infection, the doctor may prescribe:

  • Antiviral medications
  • Antibiotics
  • Steroid eye drops to reduce related inflammation

While you can treat eye infections at home, it is imperative that you get in touch with your doctor immediately if the symptoms become worse, particularly after using the prescribed medications.
