purpose: to compare the efficacy and safety of ahmed glaucoma valve (agv) implantation in the superior versus inferior quadrants. methods: this prospective parallel cohort study was performed on 106 eyes of 106 patients with refractory glaucoma. main outcome measures included intraocular pressure (iop) and rate of complications. other outcome measures included best-corrected visual acuity (bcva...

AIM To review surgical results of the Armenian Eye Care Project's (AECP) efforts in paediatric glaucoma and to identify additional morbidity associated with its initial itinerant nature. METHODS A non-randomised, retrospective historical cohort study of complicated paediatric glaucoma surgeries was performed by the AECP at the Republican Eye Hospital. 38 eyes of 34 paediatric patients underwe...

BACKGROUND To evaluate the efficacy and safety of the Ahmed glaucoma valve (AGV) and the risk factors associated with AGV implantation failure in a population of Chinese patients with refractory glaucoma. METHOD In total, 79 eyes with refractory glaucoma from 79 patients treated in our institution from November 2007 to November 2010 were enrolled in this retrospective study. The demographic d...

Abstract In order to solve the problem of AGV fault detection system’s complexion and low accuracy, a convolutional neural network (CNN) based on status monitoring diagnosis method for automatic guided vehicle (AGV) is proposed. Firstly, vibration signals core components are converted into two-dimensional (2D) images. Secondly, 2D images input convolution training. Finally, trained model used m...

AIM To evaluate the long-term results and complications of ahmed glaucoma valve (AGV) implantation in refractory glaucoma. METHODS A retrospective review of 13 patients (13 eyes) with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 18 months was performed. All patients underwent a complete ophthalmologic examination and intraocular pressure (IOP) measurement ...
