AI Technical Summary

Technical Problem

Existing technologies are insufficient for highly sensitive, non-invasive early diagnosis of glaucoma, especially for early screening and diagnosis of primary open-angle glaucoma (POAG). Conventional methods lack sensitivity and fail to reflect the condition. Limited access to primary healthcare resources and low patient compliance also restrict their widespread application.

Method used

By extracting external vesicles from peripheral blood samples of POAG and cataract patients, and using mass spectrometry sequencing and immunoprecipitation separation technology, Tau protein and GFAP protein were screened as biomarkers to develop non-invasive detection products. Based on these proteins, products for the auxiliary diagnosis of glaucoma disease were developed.

Benefits of technology

It achieves highly sensitive, non-invasive diagnosis of POAG, improves the accuracy and feasibility of early diagnosis, provides a more precise reflection of pathological changes in the central nervous system and retinal tissue, and has high diagnostic efficacy.
