Dozens of millions of people around the world have sleep apnea. The condition causes several health issues, such as cardiovascular disorders, memory problems, mood conditions, and more. Now, as per a new study, sleep apnea might also cause blindness in patients with diabetes. The new research, carried on by scientists from Taiwan, noted that patients with diabetes present a higher risk of developing diabetic macular edema due to sleep apnea. Diabetic macular edema might eventually cause vision impairment or even blindness. Sleep apnea causes breathing interruptions in people with this sleep disorder. That creates a drop in oxygen levels and unrestful sleep. The lack of oxygen increases the risks of brain issues, hypertension, cardiovascular diseases, and even type 2 diabetes. Accordingly, people with sleep apnea should not ignore the condition and seek treatment as soon as possible. A New Study Concluded That Sleep Apnea Might Cause Blindness In Patients With Diabetes According to the Taiwanese Scientists, sleep apnea triggers increased damage to the blood vessels in the eyes of people with diabetes. Known as diabetic retinopathy, the sleep apnea-triggered condition in people with diabetes might eventually lead to blindness. The scientists reviewed the data collected from the patients diagnosed with diabetic retinopathy from the Taiwanese Chang Gung Memorial Hospital. Overt eight years, the researcher followed the patients. The results of the study revealed that those patients who also had sleep apnea presented worse diabetic macular edema. Now, the researchers hope that the outcomes of the research would increase the awareness of the importance of treating sleep apnea, especially in people with diabetes. "Based on these results, we hope that more medical professionals will approach sleep apnea as a risk factor for diabetic macular edema. This could allow for earlier medical intervention so patients can keep more of their vision and preserve their overall health as much as possible," said Juifan Chiang, the study's leading author.
