Active clinical trials for "Photophobia"

The purpose of this mechanistic study is to examine light sensitivity (melatonin suppression) in people with bipolar depression I, and compare it to healthy controls. This is not a treatment study.

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.

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.

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.
