Modeling techniques are an essential complement to clinical studies of the retina, as they provide access non-measurable parameters throughout network and enable simulation controlled disturbances or pathologies. In this work, we propose development a patient-specific one-dimensional model arterial circulation in retina. Our is based on conservation laws utilizes morphometric velocimetric data ...

purpose: to evaluate the outcomes of internal tamponade using heavy silicone oil in complicated retinal detachment (rd) surgery. methods: in this interventional case series, patients with complicated rd involving the inferior retina were enrolled. inclusion criteria included rd secondary to proliferative vitreoretinopathy (pvr cp6 and/or ca6) involving the inferior retina, inferior or posterior...

Introduction: Age-related macular degeneration (AMD) is one of the major causes of visual loss among the elderly. It causes degeneration of cells in the macula. Early diagnosis can be helpful in preventing blindness. Drusen are the initial symptoms of AMD. Since drusen have a wide variety, locating them in screening images is difficult and time-consuming. An automated digital fundus photography...

Introduction: The aim of the present study was to determine burn intensity in retinal laser photocoagulation based on laser parameters; wavelength, power, beam size and pulse duration, using Optical Coherence Tomography (OCT), fundus camera, physical eye model and computer simulation in a clinical study.Materials and Methods: Participants were 10 adult patients between 50-80 years with prolifer...

Human vision comprises different structures whose physiological functions act as variable for a healthy human vision. Retina plays vital role in vision, hosting cells and neuron ten layers. The perikaryal of these neurons are segregated from neurological processes, forming discrete layers1. inner retina includes ganglion amacrine cells, whereas the outer rod cone photoreceptors. primary photore...
