Participants are wanted for a study into the association between vision impairment and sleep, health, and wellbeing. The researchers are keen to identify the effects of different conditions including aniridia.

Many people with aniridia experience sleep issues which may be related to having hypoplasia, and other anomalies such as with the pineal and pituitary glands.

Sleep and biological daily (circadian) rhythms are essential to maintaining the healthy balance and functioning of the mind and body. Our master internal circadian clock coordinates our body’s daily physiological and behavioural cycles to the Earth’s solar day. This includes daytime alertness and sleep timing, to synchronization of changes in hormone secretion, to fluctuations in mood and cognitive ability.

The researchers are based in Oxford and want to hear from people with visual impairments from around the UK.

Find out more about the research and take the survey that forms its first part. Make sure you highlight that you have aniridia in your answers.
