Epiretinal Membrane
This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.
Epiretinal membranes (ERM) consist of an abnormal growth of tissue across the retina and are present about 6% of people aged 50 and over. They can cause symptoms of distortion (straight lines appearing bent) or blurred vision. Management options include observation if asymptomatic, or surgery to peel the membrane if symptomatic. Limited data exists regarding how to identify patients who are most likely to benefit from surgery.
We propose to measure the effects on distortion (using D chart), visual acuity and vision-related quality of life (using a validated vision-related quality of life questionnaire) of ERM surgery. This will allow us to investigate whether pre-operative D chart score can predict subsequent improvement in quality of life following surgery. We hope the results will help patients and VR surgeons decide whether or not to proceed with ERM surgery.
The study will be a prospective case series consisting of patients with symptomatic epiretinal membranes who choose to have epiretinal membrane surgery. The study participants will get standard care with the additional administration of a quality of life questionnaire and measurement of distortion (using a D-chart) at 3 different time points (pre-op, and post-op at 26 and 52 weeks). Recruitment will be in Glasgow, with a possibility of other sites being added on at a later stage.
Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.
