Mindfulness Based Cognitive Therapy Modified for Visual Symptoms (MBCT-vision) — MBCT-vision  

Photophobia Clinical Trial

Official title: Mindfulness Based Cognitive Therapy Modified for Visual Symptoms: MBCT-vision

Status Completed

Clinical Trial Summary

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.

Clinical Trial Description

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. Mindfulness-Based Cognitive Therapy is a treatment that combines evidence-based approaches of Mindfulness-Based Stress Reduction and Cognitive Behavioural Therapy (CBT). MBCT is an established 8-week programme designed to develop skills of mindfulness and CBT strategies in individuals, through weekly small-group sessions and structured daily practice between sessions. Studies on MBCT and mindfulness-based interventions have shown improvements in psychological resilience; physical health including immune function; and neural changes associated with psychological wellbeing. The investigators propose that MBCT, modified to incorporate aspects relevant to persistent and distressing visual symptoms (MBCT-vision), can improve these debilitating symptoms by modifying dysfunctional neural pathways and equip patients with skills that promote psychological resilience and improve coping with residual symptoms. For this study, the investigators will assess the use of MBCT-vision in patients with visual snow or associated visual symptoms, migrainous visual aura or photophobia. This will be the first study of a mindfulness-based intervention in this population. ;
