Diagnostic medical device for stabilized image perception of retinal blood vessels using entoptic phenomena

Blog Article

A diagnostic medical tool is described that allows patients to non-invasively observe, describe and document their own retinal blood vessels using the Purkinje vascular entoptic test.We envision key applications of the Purkinje retinal Xbox Series X image stabilization (PRIS) device in monitoring of diabetic retinopathy and cost-effective assessment of retinal visual acuity.To optimize our PRIS principle, we have developed a benchtop device with interchangeable light modules.The modular design is intended to provide maximum flexibility for determining appropriate PRIS Kone Kettle stimulation parameters.In self-tests, we found that a pleasant entoptic perception occurs when a green luminous light spot (approx.

525 nm) moves on a circular path.The challenging part is to derive an objective diagnosis from a subjective phenomenon.
