Late-Onset Bleb Leaks After Glaucoma Filtering Surgery

Abstract

AQUEOUS leakage from a conjunctival filtering bleb may occur as an early or late complication of glaucoma filtration surgery. If the leakage is left untreated, vision-threatening complications may result, including ocular hypotony and maculopathy, shallowing of the anterior chamber, peripheral anterior synechiae, cataract formation, corneal decompensation, choroidal effusion, suprachoroidal hemorrhage, and endophthalmitis. Although many treatment options have been proposed,^1-15 successful closure of late bleb leaks following glaucoma filtering surgery remains a controversial and challenging management problem.
