Ocular surface infections refer to infections that affect the front part of the eye, including the cornea and the conjunctiva. These infections can be caused by bacteria, viruses, fungi, or parasites, and may affect one or both eyes.

​

The most common of ocular surface infections are:*

 

Conjunctivitis (Pink Eye): an inflammation of the conjunctiva, often caused by a bacterial or viral infection. It can result in redness, itching, tearing, and discharge. 

 

Bacterial Keratitis: An infection of the cornea that can cause pain, redness, light sensitivity, and blurry vision. It is often associated with contact lens wear and requires immediate treatment to prevent vision loss.

 

Viral Keratitis: Commonly caused by the herpes simplex virus (HSV), this type of keratitis can lead to pain, redness, and eye irritation. It can cause recurrent infections if not managed properly.

 

Fungal Keratitis: This is a rare but serious eye infection caused by fungi, often from injury involving plant material or prolonged contact lens use. Symptoms include eye pain, redness, and blurred vision.

 

Blepharitis: A common inflammation of the eyelids that causes redness, swelling, and irritation. It occurs when the oil glands at the base of the eyelashes become clogged, leading to discomfort and crusting around the eyelashes. Blepharitis can be chronic and is often associated with dry eyes or skin conditions like rosacea.
