Reproducing Glaucoma-like Elevated SRTs: by Desensitizing a Healthy Human Retina using Half-field and Localized Photobleaching

Glaucoma impacts vision by affecting visual processing at the retinal ganglion cell level. To recreate its impact on visual processing, photobleaching has been proposed to reversibly and temporarily induce glaucoma-like saccadic reaction time. It has been established that photobleaching elevates the threshold detection levels of visual stimuli...

Contactless Heat Measurement System for Retinal Coagulation: Design and Evaluation

Introduction: Current heat measurement systems for retinal coagulation are insufficient to demonstrate the safety of intraocular diathermy instruments. Therefore, this paper aims to design and test a novel coagulation heat measurement system that attempts to infer direct retinal tissue temperature using contactless thermal measurements. Methods:...

Vitreous Wipe: A new test prototype

Retinal detachment occurs when liquid slips behind the retina and does not allow the latter to lay flat on the posterior region of the eye. It alters the vision of the patient, hence requiring surgery to be corrected. In some cases, retinal detachment can occur after the retina has been treated for other pathologies. <br/>Indeed, more than 20%...

An Automated System for the Detection and Classification of Retinal Changes Due to Red Lesions in Longitudinal Fundus Images

People with diabetes mellitus need annual screening to check for the development of diabetic retinopathy. Tracking small retinal changes due to early diabetic retinopathy lesions in longitudinal fundus image sets is challenging due to intra- and inter-visit variability in illumination and image quality, the required high registration accuracy...

Development of a Retinal Eye Tracker for 3D Optical Coherence Tomography

Several eye diseases appear in the posterior part of the eye, i.e. the retina or fundus. Retinal images therefore provide valuable information to identify eye diseases. Optical Coherence Tomography (OCT) is a 3D imaging technique that can image the retina with a resolution and depth penetration that can not be achieved by any other non-invasive...
