Abstract: A computer-readable medium includes computer-executable instructions that cause a processing unit of a user device to instruct a user to stand a predetermined distance from the user device, acquire an image of the user, and determine a user interpupillary distance based on the acquired image. The user interpupillary distance indicates a distance between the user's pupils in terms of pixels. The computer-executable instructions further cause the processing unit to determine a current distance between the user and the user device based on the user interpupillary distance, a predetermined interpupillary distance, a width of the acquired image in terms of pixels, and a field of view of the camera. Additionally, the computer-executable instructions cause the processing unit to display the current distance between the user and the user device on a display and display an eye chart when the determined current distance is equal to the predetermined distance.

Abstract: Examples of devices and method for quantifying opacities in an eye are shown. Examples include analysis of still images or video images. In one example a cross section area of opacities within a visual axis are quantified. Opacities in the vitreous of an eye, such as “floaters” can vary in severity from little or no reduction in vision, to bothersome, to high reduction in visual function. It is desirable to be able to quantify a level of severity of visual obstruction within a patient's eye and proceed with a level of treatment to match the condition.

Abstract: Glaucoma is the second most common cause of blindness in the global world. It is a multifactorial disease with several risk factors, of which intraocular pressure (IOP) is the most important. IOP measurements are used for glaucoma diagnosis and patient monitoring. IOP has wide diurnal fluctuation, and is dependent on body posture, so the occasional measurements done by the eye care expert in clinic can be misleading. We provide an implantable sensor, based on microfluidic principles, which in one example has 1 mmHg limit of detection, high sensitivity and excellent reproducibility. This sensor has an optical interface, which enables IOP to be read with, for example, a cell phone camera. The design, fabrication, along with the option of self-monitoring are promising steps toward better patient care and treatment for this devastating disease.
