ClinConnect Summary

Open Angle Glaucoma (OAG) is an eye disease which can lead to irreversible loss of vision caused by damage to the optic nerve at the back of the eye. It is often associated with raised fluid pressure in the eye and treated by lowering this pressure. However, despite treatment, some patients continue to lose vision and it is suspected that other factors are contributing to the optic nerve damage. Among them is Obstructive Sleep Apnoea (OSA), though the link between OAG and OSA is controversial.

This study aims to determine whether the prevalence of OSA is higher in patients with OAG in comp...
