Glaucoma is one of the principal causes of blindness in the world1. It is an illness which has an asymptomatic form until advanced stages, thus early diagnosis represents an important objective to achieve with the aim that people who present Glaucoma maintain the best visual acuity throughout life, thereby improving their quality of life. An Artificial Neural Network (ANN) is proposed for the d...

We propose a model, based on a quantum stochastic differential equation QSDE , to describe the scattering of polarized laser light by an atomic gas. The gauge terms in the QSDE account for the direct scattering of the laser light into different field channels. Once the model has been set, we can rigorously derive quantum filtering equations for balanced polarimetry and homodyne detection experi...

Glaucoma is an eye disease that can lead to permanent blindness caused by increased Intraocular Pressure (IOP). There are several methods detect glaucoma, namely Optical Nerve Hypoplasia Stereo Photographs (ONHSPs), Coherence Tomography (OCT), Scanning Laser Polarimetry (SLP), and Confocal Ophthalmoscopy (CSLO). However, these require a lot of money expert supervision. In this paper, glaucoma c...

PURPOSE To determine whether acutely elevated intraocular pressure (IOP) alters peripapillary retinal thickness, retinal nerve fiber layer thickness (RNFLT), or retardance. METHODS Nine adult nonhuman primates were studied while under isoflurane anesthesia. Retinal and RNFLTs were measured by spectral domain optical coherence tomography 30 minutes after IOP was set to 10 mm Hg and 60 minutes ...
