Eye Infections

Eye infections occur when a foreign substance, such as bacteria, viruses, or fungi, enters the eye and causes an infection. These infections can affect various parts of the eye, including the conjunctiva, cornea, sclera, and uvea.

Types of Eye Infections

• Conjunctivitis: Also known as pink eye, this is an infection of the conjunctiva, which is the thin membrane covering the white part of the eye and inside of the eyelids.
• Keratitis: This is an infection of the cornea, which is the clear dome-shaped surface at the front of the eye.
• Endophthalmitis: This is a rare but serious infection that occurs inside the eyeball, usually after surgery or injury.
• Uveitis: This is an inflammation of the uvea, which is the middle layer of the eye, and can be caused by infection or other factors.

Symptoms of Eye Infections

The symptoms of eye infections can vary depending on the type and severity of the infection. Common symptoms include:

• Redness and swelling of the eyes
• Discharge or pus in the eyes
• Itching, burning, or gritty sensation in the eyes
