An Improved Monocular Eye Position Sensor

Unmet Need There is a need for very fast eye position sensors. Video systems are still too slow to be used for eye tracking in many demanding ophthalmologic and neurologic applications. Technical Overview Johns Hopkins faculty members, Dr. Boris Gramatikov and Dr. David Guyton, have invented a novel class of technologies for very fast detection of...

Compensating for Polarization Changes Introduced by Components with Retardation in Polarization Sensitive Retinal Scanning Systems

Unmet NeedThe most sensitive part of the human retina, the fovea, changes the polarization state of light when scanned with a low-power polarized beam of light. This produces a particular pattern which can be used for eye tracking or monitoring central fixation. The latter is useful in diagnosing strabismus (cross-sightedness) and amblyopia (“lazy eye”),...

Head-mounted Indirect Ophthalmoscope Camera Using a Smart Device

Unmet NeedFundus imaging is the sub-field referring to the imaging of the eye and other hollow organs. Most current fundus imaging devices are impractical for some patients such as young children and patients who are bedridden. It is also important to note that taking images and/or videos is useful in fundus imaging rather than simply having the medical...
