Types of Eye Infections
Eye infections are common conditions that can affect various parts of the eye, including the eyelids, conjunctiva, cornea, and other ocular structures. Here are some common types of eye infections:
1. Conjunctivitis (Pink Eye)
Conjunctivitis is the inflammation of the conjunctiva, a thin, transparent layer covering the white part of the eye and the inner surface of the eyelids. It can be caused by viral or bacterial infections, allergies, or irritants. Symptoms include redness, itching, discharge, and swollen eyelids.
Blepharitis is an inflammation of the eyelids, usually caused by bacteria or skin conditions. It can result in red, swollen, and itchy eyelids, along with flaky skin and crusting at the base of the eyelashes.
Keratitis is an infection of the cornea, the clear front surface of the eye. It can be caused by bacteria, viruses, fungi, or parasites, and may result in eye pain, redness, blurred vision, sensitivity to light, and discharge.
4. Stye (Hordeolum)
A stye is a red, painful lump that forms on the eyelid, usually caused by a bacterial infection in an eyelash follicle or oil gland. It can cause swelling, tenderness, and discomfort, and may eventually develop into a pus-filled abscess.
Chalazion is a painless lump or cyst that forms on the eyelid, typically due to a blocked oil gland. It can cause swelling, heaviness, and blurred vision if it presses against the eye.
Endophthalmitis is a severe infection that affects the interior structures of the eye, including the aqueous humor, vitreous humor, and retina. It can occur as a result of trauma, surgery, or the spread of infection from other parts of the body. Symptoms include eye pain, redness, decreased vision, and severe inflammation.
7. Orbital Cellulitis
Orbital cellulitis is an infection of the tissues surrounding the eye, often caused by a bacterial infection that spreads from the sinuses or nearby structures. It can lead to pain, swelling, redness, fever, and limited eye movement.
These are just a few examples of common eye infections. If you experience any symptoms of an eye infection, it is essential to seek prompt medical attention from an eye care professional. They can provide a proper diagnosis and recommend appropriate treatment to manage the infection and prevent any potential complications.
