Filter by:This is a research study on Mindfulness-Based Cognitive Therapy for visual symptoms (MBCT-vision), to treat patients with debilitating symptoms of visual snow (VS) and is associated visual symptoms, severe light sensitivity (i.e. photophobia) and migrainous visual aura. Participants will receive an intervention of an 8-week MBCT course modified for visual symptoms, which will involve 8 weeks of once weekly group sessions and home practice between sessions.
The purpose of this project is to provide a new framework for diagnosing and monitoring treatment of light sensitivity and headache by objective measurement of facial features, pupil responses, retinal electrical responses and autonomic nerve responses to light.
Photophobia is a common and disabling symptom in patient with dry eye syndrome. The aim of this study is tried to better understand this complain analyzing brain activation during a luminous stimulation to highlight modification of cortical activation.
Development of a new mass spectrometry-based biomarker for the early and sensitive diagnosis of Cystinosis disease from the blood
After a head injury, many people find that exposure to light causes them increased discomfort. By measuring how the pupil in the eye constricts to flashes of red and blue light, this study will investigate whether this phenomenon is due to a change in the eye's sensitivity to light.
The purpose of this study is to determine if a special coating, applied to the surface of glasses can reduce the frequency and severity of migraine headaches in children and adolescents. This study is being conducted by researchers at Primary Children's Medical Center, The John Moran Eye Center, and the University of Utah Department of Electrical Engineering. The investigators have determined that a specific frequency of light is particularly bothersome to migraine patients. The coating they've developed is designed to block this frequency of light. Very few treatments are approved for the treatment of childhood migraine. The investigators hope that these glasses will provide a safe way to improve headaches in children.
Pupillary dilation induced by mydriatic agents during Retinopathy of Prematurity exams can persist for hours. Despite regular use of eye protection for mydriatic-induced light sensitivity for infants, children and adults, eye protection after mydriasis has not been addressed in neonates. This study examines the use of eye patches to protect the dilated pupil from light exposure and their impact on vital signs and pain scores. prevents tachycardia, tachypnea and discomfort in neonates after ROP screening.
Approximately 9% of men and 18% of women suffer from migraine headaches. Almost all migraine sufferers report light sensitivity during a headache. Some people with migraine report that light can trigger their migraines and some people with migraine are light sensitive all of the time. The investigators have recently determined that certain colors of light are more likely to trigger migraines than other colors. In this study the investigators want to know if people who wear glasses that block these colors of light will have fewer migraine headaches.
The purpose of the study is to show the efficacy of a single dose of PRO-513 for treating subjects suffering moderate pain form a migraine attack, with or without aura. The study is also intended to show the effectiveness of PRO-513 for associated symptoms of nausea, photophobia, and phonophobia due to a migraine attack.
