Title:
ANGIO-OCT-BASED DYNAMIC FUNCTIONAL RETINAL BLOOD FLOW IMAGING APPARATUS AND IMAGING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/000846
Kind Code:
A1
Abstract:
Provided is an angio-OCT-based dynamic functional retinal blood flow imaging apparatus, comprising an angio-OCT sample optical path and an angio-OCT signal acquisition path, and further comprising a visual stimulation module arranged on the same axis as a sample arm optical path, the visual stimulation module projecting a stimulation image to different parts of the retina in the eye by means of a heat mirror DM. Further provided is an imaging method for an angio-OCT visual stimulation-induced retinal dynamic functional blood flow change image of an angio-OCT-based dynamic functional retinal blood flow imaging apparatus. The apparatus and the method focus on the functional characteristics of a visual system, and based on the special functional unit, "vascular nerve coupling", of a central nervous system, dynamic functional retinal blood flow imaging combined with visual stimulation is developed on the basis of existing angio-OCT imaging technology, thereby further improving the ability of existing angio-OCT in the aspects of early diagnosis and disease progression judgment of retinal vascular diseases, and developing the detection capability of angio-OCT on early diagnosis and disease progression of retinal neurological diseases such as glaucoma.
