Glaucoma valve implants have been observed to cause scleral indentatio
n and flattering. The authors report the case of a 79-year-old woman w
ho had previously undergone glaucoma valve implantation, and who subse
quently developed chorioretinal folds that corresponded to the implant
in location and configuration. Accumulation of fluid behind the impla
nt, as documented by B-scan ultrasonography, appeared to result in the
observed scleral an chorioretinal charges. The authors conclude that
chorioretinal folds can result following glaucoma valve implantation.
