详细描述
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 its associated visual symptoms, severe light sensitivity (i.e. photophobia) and migrainous visual aura.
VS is a condition of persistent flickering dots, like that of an out-of-focus analog television screen, affecting the whole visual field. There can be associated visual symptoms such as after-images, and trailing of images. No clinical trials for treatment have been done for VS. Instead, treatment data comes from patient case reports.
Photophobia describes discomfort or pain to light stimulation. Causes include eye surface issues, migraine, or of an unknown trigger, and can be persistent despite optimum management of underlying causes.
Patients with migrainous visual aura may have troublesome visual disturbances despite optimum migraine treatment.
Previous studies have shown that dysfunction in brain pathways contribute to the above conditions.
