Types of Corneal Infections
Infections may be bacterial, viral, fungal or protozoal.
The most prevalent type of keratitis (corneal infection) we come across is bacterial keratitis. It is most frequently encountered when the patient leaves his/her contact lenses on overnight. Falling asleep with your contact lenses on greatly increases the risk of a corneal infection. Thus it is every eye specialist’s recommendation that you remove your contacts daily, keep a regimen of thorough cleaning and rinsing habits, and always keep them in fresh contact solution.
Certain types viruses and fungi can also give rise to corneal infections. Bacteria is present everywhere, even in tap water. It is known that tap water can contain a type of bacteria that may cause corneal infections in those susceptible to it. Contact lens users are more at risk of developing this infection over those that do not use contact lenses. As such, do note that it is never a good idea to keep your contact lenses in tap water, even when your current bottle of contact lens solution has finished.
Corneal infections may or may not be infectious. Non-infectious corneal infections can arise from:
- Eye trauma or injury from scratches or sharp object
- Allergies arising from substances on contact lenses
- Certain chemicals, even those contact lens solutions
- Dry Eyes
Symptoms of a Corneal Infection
Possible symptoms of a corneal infection developing may include:
- Burning Sensation
- Increased sensitivity to light
- Watery Eyes
- Decreased Visual Acuity
- Crusty or discharge from eye
In some cases, location at which the infection takes is actually visible, forming a white spot on the eye. Contact lens users have to watch out for symptoms such as redness and irritation, as it may be a form of infectious keratitis. The depth of the infection directly correlates to how uncomfortable or painful the symptoms get. It is of utmost importance to contact your eye doctor immediately if you are a contacts lens user and experience the above-listed symptoms.
