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 : A tandem automated guided vehicle (AGV) system deals with grouping workstations into some non-overlapping zones , and assigning exactly one AGV to each zone. This paper presents a new non-linear integer mathematical model to group n machines into N loops that minimizes both inter and intra-loop flows simultaneously. Due to computational difficulties of exact methods in solving our pr...

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 ...

AIM To determine the sensitivity and specificity of three newly developed pulse oximeters in the detection of hyperoxaemia, defined as an arterial partial pressure of oxygen (PaO(2)) of > 80 mm Hg. METHODS SpO(2) readings from three oximeters (Agilent Viridia (AgV), Masimo SET (MaS), Nellcor Oxismart (NeO)) were documented in 56 infants (median gestational age at birth 35.5 weeks, range 24-41...

Objective: To describe the management options for exposed silicone Ahmed glaucoma valve (AGV) implant. Methods: This was carried out as a retrospective chart review at a tertiary care eye hospital in Southern India. Medical records of six subjects managed for AGV exposure from 2006 to 2013 were reviewed. Results: All six eyes had explantation of the AGV and 3 of them had reimplantation in a dif...
