PURPOSE To determine the morphometric parameters of filtration blebs of a valved aqueous humor drainage device. MATERIALS AND METHODS Orbital magnetic resonances imaging (MRI) was taken after implantation of an Ahmed valve (FP7 model). Outcomes of the analysis were intraocular pressure (IOP) and the bleb's morphometric analysis (volume, height, major and minor axis). Associations between IOP ...

PURPOSE To present the long-term results of Ahmed glaucoma valve (AGV) implantation. METHODS Consecutive case series of 94 eyes with AGV implantation over 7 years. Temporary tube ligation with C3F8 gas fill was used in high-risk eyes (group G&L) and compared with standard implantation in both phakic (group A) and pseudophakic/aphakic eyes (group B). Success was intraocular pressure (IOP) of 6...
