New method detects diabetes and prediabetes by analyzing the eye

According to a new study, presented at the annual meeting of the European Association for the Study of Diabetes (EASD), it is possible to predict type 2 diabetes or the condition of “prediabetes” by analyzing the lens in the eye.

The study was conducted by Mitra Tavakoli, of the Medical School of the University of Exeter. According to Tavakoli, it is possible to predict who will develop type 2 diabetes or prediabetes by measuring the level of autofluorescence in the eye lens.

This method could help with the delay of diabetes diagnosis: from the onset of type 2 diabetes to the diagnosis, in fact, it can take several years and this can make less fruitful medical interventions to prevent complications.

The same researcher has used a newly developed biomicroscope that performs a deep scan of the eye to assess possible states of advanced glycation products (AGE). The increase in these products contributes to the development of various diseases and complications of diabetes, including retinopathy and neuropathy.

This new microscope uses a blue light beam and performs a non-invasive analysis. “The results of this preliminary study showed that the autofluorescence of the lenses is significantly higher in patients with prediabetes and type 2 diabetes. The level of AGE products was related to blood sugar levels,” says Tavakoli.
