METHOD AND APPARATUS FOR DIAGNOSING AND MONITORING EYE DISEASE

摘要

Embodiments of the present invention provide method and apparatus for diagnosing and monitoring eye disease such as, for example, glaucoma. In particular, embodiments of the present invention analyze OCT scans of a retina to determine one or more of the following measures for diagnosing and monitoring glaucomatous retinal nerve fiber layer ("NFL") change: an NFL thickness; a ratio of NFL thickness in a vertical quadrant (superior and inferior quadrants in an OCT scan are combined in a vertical average) and a horizontal quadrant (nasal and temporal quadrants in the OCT scan are combined in a horizontal average); and an NFL signal ratio ("NSR") of a sum of signal strengths in a predetermined portion of the NFL and a sum of signal strengths in a predetermined region below a retina-pigment epithelium ("RPE") interface.
