Delayed-onset streptococcus pyogenes endophthalmitis following Ahmed glaucoma valve implantation.
BACKGROUND
To report a case of delayed-onset Streptococcus pyogenes endophthalmitis following implantation of an Ahmed glaucoma valve.


METHODS
A 10-year-old patient presented with acute endophthalmitis 1 year after Ahmed glaucoma valve implantation.


METHODS
The conjunctiva and Tenon's capsule over the valve plate had been penetrated by one of the polypropylene fixation sutures. The valve was removed, and pars plana vitrectomy was performed. Vitreous specimens and removal of the discharge over the plate revealed Streptococcus pyogenes.


CONCLUSIONS
This is the first documented case of Streptococcus pyogenes endophthalmitis following Ahmed glaucoma valve implantation. We think the conjunctival buttonhole caused by the polypropylene suture provided an entry site for the infection.
