Technology for vascular health

Detect cardiovascular diseases years in advance – when they are still preventable!

Microcirculation is life

More than 80% of cardiovascular diseases can be prevented if the risk factors are identified and eliminated in time.

But most people don’t know their own cardiovascular risk.

The microcirculation is the functionally crucial endpoint of the cardiovascular system

Despite the importance of the microcirculation to human health, accurate noninvasive measurements have not been possible in the past.

We offer new perspectives for diagnostic care.

Detect cardiovascular disease years in advance when it is still treatable!

Functional vascular changes can be detected using risk markers – long before the first morphological damage becomes apparent.

With our Retinal Vessel Analysis technology, we set the gold standard and are highly recognized in the scientific community.

Our product areas

Our algorithms for static vessel analysis allow a non-invasive and contact-free examination of the morphology of retinal vessels. This is associated with general vascular health and the global state of microcirculation and is therefore an integral part of modern cardiovascular diagnostics .

Our dynamic vessel analysis is a globally unique method for the non-invasive examination of the function and autoregulation of retinal vessels using video sequences. The vascular caliber along the vessels is recorded and analyzed in a time-variant manner on the retina .

With the RCrodent systems, Imedos offers the only commercially available solution for non-contact imaging and fluorescein angiography for the smallest eyes. We provide you with the tools for simple static and dynamic examination of the microcirculation , including on the animal model.

Ophthalmodynamometry

With the IOPstim system, Imedos is the only provider to offer a simple and painless increase in intraocular pressure for research as a prerequisite for the gentle measurement of retinal venous pressure for improved diagnosis of eye diseases such as glaucoma.

Cardiology

In addition to the important and efficient assessment of the cardiovascular risk of your patients, the methods of retinal vascular analysis are also suitable for various applications in clinical routine. For example, there is a discrepancy between standardized risk scores and the occurrence of coronary heart disease in women.

Ophthalmology

Impaired blood flow in the eye is often the cause of the occurrence or progression of many eye diseases. Imedos' technology makes it possible to diagnose these vascular components and then check the effect of a therapy.

Neurology

Pathologies of the microcirculation are associated with diverse clinical pictures in neurology. Therefore, the parameters of Retinal Vessel Analysis are suitable to draw conclusions about the risk of stroke, the severity of cerebral vascular diseases or other neurological diseases such as Alzheimer's disease.

Cardiometabolic prevention

The aim of cardiometabolic prevention is to prevent or delay the development and manifestation of vascular diseases at an early stage. The parameters of retinal vascular analysis offer new possibilities to extend the established gold standards of macrovascular diagnostics through microcirculation.

Nephrology

Recent studies have shown associations between changes in the retinal vessels, arterial hypertension and renal changes. An example of this are results showing the correlation between venous dysregulation and mortality in patients with end-stage chronic renal failure. In these studies, our dynamic vascular analysis represents a novel diagnostic tool for risk stratification.

Hypertensiology

Around 1.3 billion people worldwide suffer from hypertension. However, as this disease is usually asymptomatic in the beginning, a good half of these patients are unaware of their illness and the associated risk. The microvessels of the retina are very sensitive to changes in blood pressure and thus often provide the first clues to development or pre-existing disease.

Our users

"The software is really intuitive and offers clinicians a much greater scope of practice in the care of their patients. Being able to record accurate changes in retinal vessel diameter and link this with a patient's cardiovascular risk profile will make a huge difference in the level of care that we can offer our patients going forward."

"As an ophthalmologist, I had heard about the retinal vascular analysis method many years ago and was familiar with the approach. However, I only realized the comprehensive importance and benefits of the screening tool for assessing vascular health after a dramatic experience in my own family."

"Unfortunately, hypercholesterolemia is a problem that is still far too underestimated by many colleagues today. In addition to routine diagnostics, retinal vascular analysis helps us to identify patients at risk at Jena University Hospital in order to optimize treatment at an early stage and prevent cardiovascular events such as heart attacks and strokes."

“Für die klinische Kreislauf-Forschung ist eine hoch reproduzierbare Messung der Reaktion retinaler Gefäße auf vasoaktive Substanzen von höchster Bedeutung. Mit dem IMEDOS-System steht ein derartiges Messverfahren zur Verfügung, welches sich sowohl zur individualisierten Therapie einzelner Patienten als auch für klinische Studien an Kollektiven mit unterschiedlichen vaskulären Erkrankungen nutzen lässt.”

"As an ophthalmologist, I am often referred patients by cardiologists. They ask me to assess the vascular condition (AV ratio) of their patients in order to consolidate their decision on antihypertensive therapy when the data situation is uncertain. The AV ratio, which previously always had to be estimated subjectively, can be measured with the Imedos device. When I look back at my patient files and compare the measured AV ratio (Imedos) and the estimated AV ratio (me), I realize how well the money for this device was spent."

The dynamic retinal vessel analysis by Imedos has been an instrumental part of our research to understand vascular contributions to cognitive decline in aging and age-related diseases. Considering the fact that eye is the part of the central nervous system that is located outside of the cranium, assessment of dynamic changes in the retinal vasculature in response to photoreceptor stimulation provides a unique approach to directly visualize neurovascular responses in the brain. Our on-going clinical studies and clinical trials in young and aged healthy participants, as well as in participants with age-related diseases, indicate that dynamic retinal vessel analysis may provide an important tool for identifying individuals at risk for vascular cognitive impairment and dementia.

„Through many years of research in cooperation with Imedos, it was possible to progress the methodological development of the technical basis for the vascular analysis of the retina. In particular, the use of electro-optical principles in the Imedos Dynamic Analyzer enables a more patient-friendly provocation of the retinal microcirculation, while at the same time maintaining the quality of the analysis.”

„Intraocular pressure is an important risk factor in ophthalmology. In glaucoma in particular, however, vascular factors such as disorders of vascular autoregulation and reduced blood supply to the optic nerve play an equally important role. These vascular parameters can be examined non-invasively with Dynamic Vessel Analysis.“
