Project Description Heading link
This project aims to condense an existing setup used to observe the microvascular rheology in real time of patients undergoing hemodialysis due to renal failure. Ophthalmologists are interested in observing the changes of the microvascular rheology in real time as the patient undergoes the procedure by means of a high powered capillaroscopy system called a CapiScope. The current setup being used involves the patient being seated while their head would rest onto a slit lamp system. The CapiScope is mounted on a moveable arm which is positioned to observe the erythrocyte movement occurring in the conjunctiva of the patient’s eye. The issues with this system stem from the lack ofportability as well as the shakinessin recorded videoswhich result froma combination of an unsteady head and the natural, random vibrations that occur in the eyecalled micro saccades. A modular goggle setup offers a solution to these two issues by reducing the size of the entire setup and keeping the camera in sync with the head’s movements. To combat the issue of the micro saccades, a simple paper cutout was used as a fixation point for the userthat greatly improved eye stability through experimental methods. By creating this modular goggle setup, improvements in stability were observed, portability was achieved, and the existing configuration was simplified to a much more cost effective solution.
