bleb-infection
A bleb-infection is an infection that develops in or around a surgically created fluid reservoir on the surface of the eye that helps lower eye pressure. This thin, elevated area of tissue can become a route for bacteria to enter the eye, producing local inflammation or, in more serious cases, spreading inward to cause a severe internal infection. Early signs often include redness, pain, discharge, a cloudy or inflamed appearance of the surgical area, or a sudden drop in vision. Infections can remain on the surface but may progress to deeper, sight-threatening problems if not treated quickly. Risk factors include a thin or leaking surgical reservoir, trauma to the area, use of certain medications during surgery that thin the tissue, and poor eyelid hygiene. Diagnosis relies on a careful eye exam and sometimes taking samples to identify the organism responsible. Treatment is urgent and typically involves intensive antibiotic eye drops, and in more severe cases antibiotic injections or surgical repair. Preventing these infections involves good wound care, prompt repair of leaks, regular follow-up visits, and seeking immediate attention if symptoms develop, because quick action can protect vision.
