Glaucoma detection in color fundus images is a challenging task that requires expertise and years of practice. In this study we exploited the application different Convolutional Neural Networks (CNN) schemes to show influence performance relevant factors like data set size, architecture use transfer learning vs newly defined architectures. We also compared CNN based system with respect human evaluators explored integration collected from clinical history patients. accomplished best using...

To evaluate safety and clinical outcomes of a novel supraciliary device, the CyPass Micro-Stent, for surgical treatment open-angle glaucoma when implanted in conjunction with cataract surgery.Subjects (n=142) underwent combined phacoemulsification, intraocular lens insertion, microstent implantation into space study eyes (n=167). Two analysis cohorts were prespecified based upon medicated baseline pressure (IOP): ≥21 mm Hg (cohort 1, n=65) or <21 2, n=102). Glaucoma medications discontinued...

To determine and compare the retinal nerve fiber layer (RNFL) thickness, mean deviation, visual field index (VFI) in glaucoma cases with progression detected by spectral domain optical coherence tomography, standard automated perimetry (SAP), optic disc stereophotographs.The authors studied 246 eyes of 148 patients prospectively (97 cases, 132 suspects, 17 healthy eyes). SAP fields, tomography (OCT) images, stereophotographs were obtained every 6 to 12 months. Progression was determined OCT...

<h3>Background:</h3> To compare the ability of Glaucoma Progression Analysis (GPA) and Threshold Noiseless Trend (TNT) programs to detect visual-field deterioration. <h3>Methods:</h3> Patients with open-angle glaucoma followed for a minimum 2 years seven reliable visual fields were included. was assessed subjectively by four masked experts, compared GPA TNT results. Each case judged be stable, deteriorated or suspicious deterioration <h3>Results:</h3> A total 56 eyes 42 patients mean 7.8 (SD...

To evaluate the frequency and characteristics of misalignments (MAs) in retinal nerve fiber layer (RNFL) analysis protocol spectral-domain optical coherence tomography (Cirrus) determine factors associated with MAs.Three hundred eyes (162 normal 138 glaucomatous eyes) were included this cross-sectional study. The MAs considered limited when they affected only part scan line, complete (CMA) observed entire line. A subgroup (153 cases) repeated scans was analyzed to compare RNFL thicknesses...
