Diabetes and sleep apnoea may lead to vision loss: Study

Patients who suffer from both Type 2 diabetes and obstructive sleep apnoea are at greater risk of losing their vision within a period of four years, a study has found.
Obstructive sleep apnoea (OSA) is a condition where the walls of the throat relax and narrow during sleep, resulting in snoring and interrupting breathing, and it is common in patients with Type 2 diabetes.

Previous studies have shown a link between OSA and diabetic retinopathy.
However, there had been no published studies assessing the impact of OSA on the progression of diabetic retinopathy in patients with Type 2 diabetes.
“Despite improvements in glucose, blood pressure and lipid levels, diabetic retinopathy remains very common,” said Abd Tahrani from the University of Birmingham in the UK.
