The Sickle Eye Project: Prevalence of visual impairment due to sickle cell retinopathy and maculopathy in the United Kingdom

The Sickle Eye Project is looking for anyone with Sickle Cell Disease, to help us improve their eye care and vision-related quality of life. The study is open to all Sickle Cell patients regardless if they have been experiencing issues with vision or not. Participation involves completing two brief questionnaires and having eye tests and scans that are quick, painless and routine in the NHS. 

View our leaflet with more information.
