Abstract: Fixational eye movement may be analyzed to determine one or more characteristics thereof. Exemplary characteristics include measurements of microsaccade and drift measurement. These measurements may be correlated to a value for a diagnostic indicator for a neurological disorder or disease. These correlations may be used to diagnose, monitor, and prognosticate neurological disorders without administration of traditionally used neurological function tests or analysis of biological samples by which the diagnostic indicators are typically determined.

Abstract: A scanning laser ophthalmoscope and a method of operating a scanning laser ophthalmoscope are disclosed. The scanning laser ophthalmoscope includes a light source, a reflective optical system, an x- and y-coordinate scanner, and a refractive lens. The reflective optical system is configured to direct light emitted from the light source through the refractive lens to a user's eye, and to direct light reflected from the user's eye through the refractive lens to the x- and y-coordinate scanner.
