An apparatus and method for comparing entoptically observed corpuscles with computer simulated images of corpuscle-like particles without requiring the observer to view more than one screen. Also disclosed are an apparatus and method for determining and documenting the size of the foveal avascular zone (FAZ). And an apparatus and method are disclosed for determining changes in the observer's leukocyte characteristics due to blue light flicker stimulation.

Apparatus and method for determining characteristics of a human retina

An eyedrop delivery system for administering eyedrops to at least one eye of a user, wherein the system comprises a fluid reservoir for holding a supply of eyedrop fluid, a tube for conducting eyedrop fluid from the fluid reservoir to at least one eye of the user, the tube comprising at least one distal end portion terminating adjacent the at least one eye of the user, fluid driving apparatus for continuously urging eyedrop fluid from the fluid reservoir through the tube toward the at least one distal end portion of the tube, and fluid control apparatus for successively (1) permitting eyedrop fluid to flow freely through the tube so that the eyedrop fluid can begin to exit the at least one distal end portion of the tube, (2) interfering with the flow of eyedrop fluid through the tube so as to prohibit any further eyedrop fluid from exiting the at least one distal end portion of the tube, and so as to cause the eyedrop fluid leaving the at least one distal end portion of the tube to exit the at least one distal end portion of the tube as a discrete eyedrop, and (3) withdrawing the fluid remaining in the tube away from the at least one distal end portion of the tube so that the distal-most portion of the fluid is disposed within, and is substantially engulfed by, the tube, whereby the distal-most portion of the fluid can create a super-saturated vapor condition at that point in the tube.
