Inadvertent Filtering Bleb
- Wound leak under sealed overlying conjunctiva.
- May occur, particularly following cataract surgery using limbal or scleral incision techniques complicated with wound dehiscence.
- May be asymptomatic
- Tearing due to wound leaking
- Decreased vision
- Subconjunctival microcysts or bleb
- Wound gape
- Seidel test (+)
- Corneal folds
- Shallow anterior chamber
- May be complicated by hyphema, endophthalmitis, choroidal effusion, choroidal folds or papilledema.
- No treatment necessary if asymptomatic and no further risks or complications observed.
- Surgical repair by wound resuturing or bleb excision may be considered in cases with:
- Large, cystic thin-walled bleb
- Persistent hypotony
- Poor tissue apposition
- Iris prolapse
