Convolution is the main building block of a convolutional neural network (CNN). We observe that an optimized CNN often has highly correlated filters as number channels increases with depth, reducing expressive power feature representations. propose Tied Block (TBC) shares same thinner filter over equal blocks and produces multiple responses single filter. The concept TBC can also be extended to...

Purpose This study quantified the thickness and depth of the lamina cribrosa (LC) and peripapillary scleral thickness in high-resolution three-dimensional (3D) fluorescent reconstructions of the optic nerve head (ONH) in eyes from donors of African (AD) and European descent (ED). Methods A total of 64 eyes (45 ED, 19 AD) from 51 normal donors were obtained within 6 hours of death and fixed at...

PURPOSE To compare the patterns of retinal ganglion cell damage between primary open-angle glaucoma (POAG) and non-arteritic anterior ischaemic optic neuropathy (NAION). METHODS In total, 35 eyes with unilateral NAION, and 70 age- and average peripapillary retinal nerve fibre layer (RNFL) thickness-matched eyes with POAG, were enrolled as disease groups; 35 unaffected fellow eyes of the NAION...

PURPOSE To evaluate choroidal thickness (CT) in healthy and glaucomatous eyes using Swept Source Optical Coherence Tomography (SS-OCT). METHODS A cross-sectional observational study of 216 eyes of 140 subjects with glaucoma and 106 eyes of 67 healthy subjects enrolled in the Diagnostic Innovations in Glaucoma Study. CT was assessed from wide-field (12×9 mm) SS-OCT scans. The association betwe...

The use of paint thinner and glue to achieve an euphoric state has been associated with serious social and health problems in children and young adults. We present the case of a 21-year-old man with dilated cardiomyopathy occurring following abuse of paint thinner and glue containing toluene as main compound. After cessation of toluene abuse, the patient recovered rapidly and completely. Becaus...

purpose: to compare peripapillary retinal nerve fiber layer (rnfl) thickness among multiple sclerosis (ms) patients with or without a history of optic neuritis (on) and a healthy control group. methods: in this retrospective case-control study, 59 ms patients were recruited from a neurology clinic of imam hossein hospital. of which, 36 patients had at least one episode of on and 23 others had n...

BACKGROUND The purpose of this study was to examine the choroidal thickness of patients with high myopia using enhanced depth imaging optical coherence tomography (EDI-OCT) and compare them with healthy subjects. METHODS We first conducted a cross-sectional study and then performed a meta-analysis to address this issue further. Using enhanced depth imaging optical coherence tomography (EDI-OC...

PURPOSE To characterize central corneal thickness (CCT) in Latinos aged 40 or more years. METHODS A population-based cohort of Latinos from two census tracts in La Puente, California, underwent measurements of CCT and intraocular pressure (IOP). CCT was measured with an ultrasonic pachymeter, and IOP was measured by applanation tonometry. One eye of each of 1699 participants was included in t...

OBJECTIVE This study evaluated whether desiring to lose weight is associated with subsequent changes in social contact with individuals perceived to be thinner or heavier. METHODS Longitudinal data were used to examine associations between desiring to lose weight at baseline and social contact with thinner and heavier individuals across a 1-year follow-up period (N = 9,335, 2013-2014 Gallup N...

INTRODUCTION We aimed to investigate if thinner cortex of the Alzheimer's disease (AD)-signature region was related to clinical progression in patients with subjective cognitive decline (SCD). METHODS We included 302 SCD patients with clinical follow-up (≥1 year) and three-dimensional T1 magnetic resonance imaging. We estimated AD-signature cortical thickness, consisting of nine frontal, pari...
