<unk>  is the inflammation of the ocular bleb as a result of bacterial infection. It is a possible complication of a trabeculectomy performed to treat glaucoma. The causative pathogens are usually Staphylococcus or Streptococcus bacteria. Trabulectomy creates a point of possible infiltration in the bleb; the prolonged use of anti-metabolites following trabeculectomy increases the risk of bleb infection via cyst formation, epithelial wall thinning and erosion, and goblet cell depletion and decreased mucin production. Membrane deterioration, in conjunction with an inferior location for the bleb, creates a flow pathway for bacterial infiltration through the bleb's aqueous humor. Symptoms of<unk>  include ocular pain, photophobia and loss of vision, intraocular pressure, and fluid discharge. Physical examination may reveal erythema and hyperemia of the affected eye, as well as thinning and whitening of the bleb. The presence of maculopathic purulent infiltrate can also be found upon physical exam. The mainstays of therapy for<unk>  are fortified topical antimicrobial and antibacterial agents, as well as topical corticosteroids. With treatment, the prognosis for<unk>  is good. Without treatment,<unk>  can result in bleb-related endophthalmitis, leading to a much worse prognosis, including permanent vision loss and death.<unk>  is very rare; the incidence in the United States was estimated to be 550 per 100,000 individuals (.55%) from 2007-2011.
