A primary screening tool for diabetic retinopathy and other high-prevalent retinal diseases

The eye fundus is a window to the early diagnosis and evaluation of many diseases, one of which is diabetic retinopathy (DR). Diabetes mellitus (DM) has a significant impact on both health and society, and affects over 8% of the population. DR is one of the more severe complications related to DM, and early diagnosis can help reduce the rate of blindness.


  • Earlier DR diagnosis, and other high-prevalent retinal diseases, by bringing the Open Retinoscope to medical clinics. This new examination tool allows for a better and easier observation of the eye fundus than conventional ophthalmological devices.

Problem to Solve

DR is one of the leading causes of blindness in society. The potential benefits of earlier DR diagnosis could prevent the disease from progressing while it still remains asymptomatic. Regular checks of the eye fundus are therefore crucial in diabetic patients. On the other hand, patients with other high-prevalent retinal diseases, as retinal detachment, retinal haemorrhages, papilledema, or age-related macular degeneration, would benefit of an earlier diagnosis of their diseases.

Given the above, there is an urgent need to develop innovative technologies to solve the limitations of current eye fundus examination devices and avoid late diagnosis of these diseases.


The Open Retinoscope is a new device that allows clinicians to examine the retina easier and with much bigger field of vision than with any direct ophthalmoscope. It´s a primary screening tool for DR and other high-prevalent retinal diseases, and can be connected to any type of smartphone to take photos and videos, which can be shared with other health professionals.

Level of Innovation

The Open Retinoscope is portable, affordable and easy to use. It has its own light source, which allows clinicians to examine the retina freely. A functional prototype has already been developed and tested with promising results.
