Abstract: An ophthalmologic apparatus includes: an objective lens 18 configured to face a subject's eye E; an illumination optical system 1c configured to irradiate the subject's eye E with illumination light L1; a measurement optical system 1 b configured to take an interference image of corneal reflection light R1, which is a reflection of the illumination light L1, through the objective lens 18; an observation optical system 1a configured to image an anterior segment of the subject's eye E through the objective lens 18; a control unit 2 configured to process information on imaging by the measurement optical system 1b and the observation optical system 1 a; and the control unit 2 configured to simultaneously output, to a single output unit 3, tear film information calculated from the interference image by the measurement optical system 1 b, and information on the anterior segment E imaged by the observation optical system 1a.

Abstract: A medical diagnostic apparatus includes a receiver circuit that receives three-dimensional volumetric data of a subject’s eye, and a processor configured to separate portions of the three-dimensional volumetric data into separate segments, perform processing differently on each of the separate segments, and combine the separately processed segments to produce an enhanced three-dimensional volumetric data set. The processor is further configured to generate at least one diagnostic metric from the enhanced three-dimensional volumetric data set, and the processor is further configured to evaluate a pathological condition based on the at least one diagnostic metric. Related methods and computer readable media are also disclosed.
