Abstract: It aims to construct a technology in which the onset or progression of an aging state or a specific disease can be evaluated in an objective and highly reproducible manner, and in particular, to provide a method of detecting conjunctival diseases such as conjunctival MALT lymphoma, and to provide an aging biomarker that serves as an indicator of the aging state.
A method of detecting a conjunctival disease using an ocular surface tissue, the method comprising a step of comparing a microbial community structure of a microbiota included in an ocular surface tissue specimen sampled from a healthy person, with a microbial community structure of a microbiota included in an ocular surface tissue specimen sampled from a subject to detect an ocular surface tissue specimen which is sampled from the subject evaluated as having the conjunctival disease based on a change in the microbial community structure between the healthy person and the subject, and an aging biomarker for detecting an aging state, the aging biomarker comprising a bacterial species which belongs to at least one family selected from Corynebacteriaceae family and Propionibacteriales family in an ocular surface tissue.

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.
