03/12/2021The use of artificial intelligence and deep learning in medical diagnostics is growing rapidly. Ubotica’s neural network is based on deep learning and detects the presence of diabetic retinopathy in retinal images. Dr. Holger Pfeifer talks about the project successes, and reveals the obstacles researchers must continue to overcome in adopting deep learning systems.
03/12/2021Damage to the retina due to diabetes is now considered the most common cause of blindness in adults. This makes early detection of so-called diabetic retinopathy all the more important. But for diabetics living in poorer areas of the cities in India, there is a lack of adequate ophthalmological care. Therefore, the University Hospital Bonn has launched a smartphone-based telemedicine DR screening.
11/11/2021Diabetic retinopathy (DR), a complication of the retina brought about by diabetes, is one of the most frequent reasons for vision loss in European adults between 25 and 60 years of age. When detected early, treatment can effectively reduce or prevent vision loss. To date however, national screening programs have been available in only a few countries and even then, they are costly.
21/10/2021A new brain implant based on intracortical microelectrodes can allow a blind person to see shapes and letters. New research by the Miguel Hernández Univresity shows that the implantation of this micro device in the human brain can be done safely, and that the direct stimulation of the cerebral cortex produces visual perceptions with a much higher resolution than had been achieved until now.
11/10/2021Neuroscientists discovered a novel, non-invasive imaging-based method to investigate the visual sensory thalamus, an important structure of the human brain and point of origin of visual difficulties in diseases such as dyslexia and glaucoma. The new method could provide an in-depth understanding of visual sensory processing in both health and disease in the near future.
07/10/2021In geographic atrophy, a late form of age-related macular degeneration (AMD), reading ability is closely related to the altered retinal structure. This has been demonstrated by researchers from the Department of Ophthalmology at the University Hospital Bonn with colleagues at the National Eye Institute and the University of Utah.
28/09/2021For the first time ever, the intention of a continuous movement was able to be read out from non-invasive brain signals at TU Graz. This success enables more natural and non-invasive control of neuroprostheses to be carried out in real time.
08/09/2021Scientists from Nanyang Technological University, Singapore (NTU Singapore), in collaboration with clinicians at Tan Tock Seng Hospital (TTSH) in Singapore have developed a novel method that uses artificial intelligence (AI) to screen for glaucoma, a group of eye diseases that can cause vision loss and blindness through damage to the optic nerve at the back of the eye.
22/03/2021Alzheimer's disease is still incurable, but if detected early enough, countermeasures can improve treatment and slow the progression. Unfortunately, there is still no reliable early detection test at this juncture. This might soon change thanks to a non-invasive spectroscopy of the retina.
03/02/2020Regenerative medicine aims to replace damage in the body with functional tissue and restore normal function. The first defense for large defects are implants made of hydrogels, designed to promote cell growth. They need their own blood supply, which is a problem when it comes to larger implants because you cannot regulate where and how the blood vessels grow - until now.
04/11/2019Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.
02/01/2019Diabetes mellitus or simply diabetes has become very common and is often described as a lifestyle disease. More and more people are suffering from this chronic metabolic disorder. Next to established diagnostic procedures, digital retinal screening has shown to be successful - a promising technique that will also play an important role in the diagnosis of other diseases in the future.
19/12/2018Continuous monitoring is an essential process with every disease. In the case of eye disorders, frequent retina measurements can facilitate early detection of deterioration to quickly initiate intervention. This calls for comprehensive care settings, easy ways to take measurements and prompt results. However, in reality, this is rarely the case.
