Blebophthalmos: proptosis due to a massive bleb following implant surgery in refractory paediatric glaucoma.

A 5-year-old boy with failed combined trabeculotomy and trabeculectomy underwent Ahmed glaucoma valve (AGV) implantation and presented 5 weeks postoperatively, with sudden onset proptosis downward displacement of the globe, limited extraocular movements and displacement of tube from anterior chamber. CT scan of the orbits showed a large cystic bleb with posterior dislocation of the implant and was explanted. In vitro testing of implant for fluid flow characteristics revealed a dysfunctional valve with anterior leak, which could have possibly lead to anterior and inferior fluid accumulation resulting in displacement of implant, a probable cause for this rare complication.

Comparison of the New Low-Cost Nonvalved Glaucoma Drainage Device with Ahmed Glaucoma Valve in Refractory Pediatric Glaucoma in Indian Eyes.

Purpose: To compare outcomes of a nonvalved glaucoma drainage device (the Aurolab aqueous drainage device [AADI] with a valved glaucoma drainage device (the Ahmed glaucoma valve [AGV]) in refractory pediatric glaucoma.

Design: Retrospective interventional case series.

Participants: One hundred sixteen eyes of 97 children with refractory pediatric glaucoma.

Intermediate Term Outcomes of Early Posttrabeculectomy Bleb Leaks Managed by Large Diameter Soft Bandage Contact Lens.

Purpose: To study the outcomes of large diameter soft bandage contact lens (BCL) in managing early trabeculectomy bleb leak.

Materials And Methods: Of 972 eyes that underwent fornix-based trabeculectomy between 2011 and 2015, 19 eyes with bleb leak with at least 1 year follow-up were eligible. Bleb leak was conservatively managed using large diameter BCL (≥15.
