Symptoms and Causes of Eye Infection

 

There are a number of different symptoms that you might experience if you have an eye infection. They range from looking unsightly to being irritating. They can include:

  • Red eyes
  • Watery eyes
  • Itchy eyes
  • Swollen eyelids
  • Discharge from the eye

Something simple, like a small particle might be the cause of your eye irritation, for example. However, it might not necessarily lead to an infection. If you're aware that something has entered your eye, you could remove it carefully, perhaps by washing it out with an eye wash solution.

What if you have any of the symptoms listed and don't know what has caused them though? If you're in any doubt, don't take chances with your eyes. It's best to get advice from a healthcare professional or optician as soon as you can.

Causes of eye infections

Broadly speaking, there are 3 main causes of eye infections:

  • bacteria
  • viruses
  • allergy

They can all invade your eye or the area around your eye. A number of different conditions can result. Let's have a look at some possibilities: 

Infective conjunctivitis

This is quite a common condition where the conjunctiva becomes inflamed. This is the thin, clear film covering of the whites of your eyes and the inside of the eyelids. You eye will look red and may itch or be swollen and there is sometimes a sticky coating that forms on your eyelashes. Various bacteria and viruses can be the cause.

Mostly infective conjunctivitis clears up with treatment. It’s not usually serious, but it can be spread to other people. So, if you have conjunctivitis, wash your hands if you touch your eyes and don't share towels or pillows. 

Stye

A stye looks like a small pink or red bump on your eyelid. It is usually caused by an infection of the eyelid. A stye can look inaesthetic, feel sore and be annoying, but it can easily be treated. 

Corneal infections

The cornea is the tissue at the front of your eye. A corneal ulcer is an open sore in the outer layer of the cornea which is most commonly caused by an infection with bacteria, viruses, fungi or a parasite. Symptoms include red or bloodshot, itchy and watery eyes to enter the wound causing symptoms like redness, swelling and pain. Fungal keratitis can occur if your eye has been damaged by plant material. For example, if a twig or branch scratches the cornea, a fungus can be introduced into your eye, causing an infection.

Another corneal infection called acanthamoeba keratitis is known to affect contact lens wearers. This is actually caused by a parasite entering the eye and can be a serious sight-threatening infection. Contact lens wearers need to be very careful about the purity and source of their lens cleaning solutions to help prevent this problem. 

Treatment for eye infections

Eyes, as we all know, are delicate structures. So if you have any of the symptoms listed try not to rub your eye or touch it if at all possible as rubbing your eyes can make symptoms worse

 

Always read the label.
