Bleb-related infections are potentially catastrophic complications of filtration surgery.
Early recognition and management are key to bleb survival and preservation of vision.
1. DEFINITIONS
The two types of bleb-related infections are blebitis and bleb-associated endophthalmitis.
Blebitis is a term used to describe an isolated bleb infection. This is characterized by
varying degrees of localized conjunctival hyperemia, associated with a mucopurulent infil-
trate identified within the bleb or within the peri-bleb area, giving the appearance of a
“white on red” conjunctiva. Blebitis may be associated with mild to moderate inflam-
mation of the anterior segment, but typically there is no vitritis. It has been suggested
that blebitis may represent a prodromal event of endophthalmitis or a limited form of
endophthalmitis (1).
