"Diabetic retinopathy" is a condition that affects the eyes of people with diabetes. It happens when high levels of sugar in the blood damage the tiny blood vessels in the eyes, leading to vision problems and potential loss of sight.

However, prior to this research led by the University of Birmingham, published in American Journal of Respiratory and Critical Care Medicine, there had been no published studies assessing the impact of OSA on the progression
of diabetic retinopathy in patients with Type 2 diabetes.
In addition, they recently demonstrated that ADORA2A variants offer significant protection against the development of
diabetic retinopathy in type - 1 diabetes.
The patients were assessed
for diabetic retinopathy using specialist retinal imaging, while OSA was assessed using a home - based, multi-channel cardio - respiratory portable device.
It also found that prolonged delays in initiation may limit the therapeutic effect and that, although uncommon, development of
proliferative diabetic retinopathy still occurs in some eyes undergoing anti-VEGF therapy.
Dr. Rotimi's lab has shown that a polymorphism in the endothelial nitric oxide gene is associated
with diabetic retinopathy in Africans.
The study, published online ahead of print in The Journal of Clinical Investigation, has implications for treating diseases such
as diabetic retinopathy and age - related macular degeneration — the leading causes of vision loss in adults.
«Our study presents an unexpected finding that the connections between cells in the retinal blood vessels contain unusual, long - chain lipids that may keep vessels from leaking, possibly preventing
diabetic retinopathy from occurring,» said Julia Busik, lead author of the study and a physiology professor.
The Academy has released a new animated public service announcement to help educate people about the importance of regular exams and common eye diseases
including diabetic retinopathy.
Harris et al. [2] also provided evidence of the presence of retinal hypoxia in the early stages of diabetes by showing that contrast sensitivity was improved when patients with
early diabetic retinopathy were made hyperoxic.
Lead author of the study is physiology professor Julia Busik and she says: «Our study presents an unexpected finding that the connections between cells in the retinal blood vessels contain unusual, long - chain lipids that may keep vessels from leaking, possibly
preventing diabetic retinopathy from occurring.»
There are some pilot studies going on right now using near infrared light to
treat diabetic retinopathy where they're literally shining the near infrared light right into the eye.
Researchers compared how well IDx - DR
detected diabetic retinopathy in more than 800 U.S. patients with diagnoses made by three human specialists.
«We were surprised to find so many similarities between these two diseases, but most striking was that some of these common signatures are shared with other conditions
like diabetic retinopathy and age - related macular degeneration,» said William A. Beltran, senior author on the study, an associate professor of ophthalmology in Penn Vet's Department of Clinical Sciences and Advanced Medicine and director of the Division of Experimental Retinal Therapies.
Meanwhile, the study also showed that patients who received treatment for OSA using a machine connected to a face mask that delivers pressure to prevent the blockage of the airways during sleep had a lower risk of developing
advanced diabetic retinopathy compared to patients who did not receive the treatment.
Dr Tahrani added: «We can conclude from this study that OSA is an independent predictor for the progression to moderate or
severe diabetic retinopathy in patients with Type 2 diabetes.
The longitudinal study found that at a follow - up appointment, on average 43 months later, the patients with OSA (18.4 %) were more likely to develop moderate to severe
diabetic retinopathy compared to those without OSA (6.1 %).
Further evidence of hypoxia is suggested by the increases in vascular endothelial growth factor (VEGF) expression in patients with diabetic retinopathy [3 — 5] and retinopathy of prematurity (ROP)[6], because VEGF is known to be a hypoxia - inducible gene [7,8].
Additionally, they may reduce inflammatory eye disease and
even diabetic retinopathy, or damage to the eye due to living with diabetes.
In the new study, Lucentis was compared to scatter laser therapy (or panretinal photocoagulation), which has been the standard treatment for proliferative
diabetic retinopathy since the 1970s.
As better treatments for
diabetic retinopathy emerge, it's important to remember that an early diagnosis is the first step to getting treatment and saving your sight.
Competitions that are currently under way include one sponsored by the California Healthcare Foundation on
identifying diabetic retinopathy in eye images and using U.S. Forest Service data to predict types of tree cover for a given location.
«However, more importantly, we have shown that patients with OSA and Type 2 diabetes, compared to those with diabetes only, are at increased risk of developing advanced
diabetic retinopathy over a period of three years and seven months.»
Corresponding Author Doctor Abd Tahrani, of the University of Birmingham's Institute of Metabolism and Systems Research, said: «Despite improvements in glucose, blood pressure and lipid levels,
diabetic retinopathy remains very common.
The initial application to
diabetic retinopathy shows proof - of - principle in a very important disease, but the approach can be adapted to other powerful drugs and diseases where localized activity is needed.»
This follow - up study demonstrated that eyes with predominantly
peripheral diabetic retinopathy lesions during the initial study had more than a three-fold increased risk of retinopathy progression.
New Orleans — Patients with age - related macular degeneration or
diabetic retinopathy who used a mobile application to test their vision at home got comparable results to in - office vision testing, according to research presented today at AAO 2017, the 121st Annual Meeting of the American Academy of Ophthalmology.
Studies suggest that lutein and zeaxanthin help to protect photoreceptors from oxidative stress9.These caroteoids are highly recommended for not only the prevention of age - related macular degeneration, but also to protect
against diabetic retinopathy.
• Refractive errors • Cataracts • Optic neuritis, an inflammation of the optic nerve • Retinal diseases, such as a retinal tear or detachment • Macular degeneration • Glaucoma • Conjunctivitis • Diabetic eye problems, such
as diabetic retinopathy and diabetic macular edema
An unexpected finding was that many of the innate immunity pathways that were active in the late stages of these inherited blinding diseases were the same as those that are associated with more common vision disorders
including diabetic retinopathy and age - related macular degeneration, or AMD.
«Our results show that normalized blood glucose levels alone are not sufficient to fully
treat diabetic retinopathy,» said Dr. Alice Ly (PROT), lead author of the study.
Google research scientist Lily Peng, a physician, led a team that developed a machine learning algorithm to diagnose a patient's risk of
diabetic retinopathy from a retinal scan.
FDA APPROVES FIRST AI - POWERED RETINOPATHY APP: The US Food and Drug Administration (FDA) greenlit the marketing of IDx - DR, the first medical device that uses artificial intelligence (AI) to
detect diabetic retinopathy — a leading cause of blindness among people with diabetes.
