Description

Micro-optical conduit

Technical field

The present invention relates to medical domain, be specifically related to a kind of micro-optical conduit for diagnosis of glaucoma.

Background technology

Glaucoma is the first blinding oculopathy of irreversibility in the world, and it is very harmful to vision, needs getting up early therapeutic intervention with resistance The only further deterioration of glaucomatous optic damage.Uniquely confirm that effective Therapeutic Method is exactly effective through evidence-based medicine EBM clinically Control intraocular pressure.Primary open angle glaucoma, is called for short " opening green grass or young crops ", is one of modal type of glaucoma, accounts for all green lights The 60%~70% of eye, generally involves eyes, is often bilateral, and onset is slow, and intraocular pressure gradually rises, and angle, room remains open, Many without obvious subjective symptoms.Due to early screening technology, effective treatment means, the shortage of disease progression monitoring technology, China opens Blue or green blind rate remains high always.More than 40 years old crowd of China opens blue or green prevalence at present is 2.3%, blind rate about 15%, disability rate Nearly 30%.Calculate accordingly, along with the acceleration of China's aged tendency of population, it is contemplated that to the year two thousand twenty, China by have 16,400,000 open green grass or young crops Patient, produces nearly 2,460,000 blind persons and the vision disabled more than 4,900,000.The most then must carry out all the life owing to opening blue or green patient one Follow up a case by regular visits to and treat, take up to 188 to individual and society's direct economy of causing white elephant, China to thus result in every year Hundred million yuan, indirect Socie-economic loss is more than 100,000,000,000 yuan.Therefore, the blue or green weight having become serious harm our people's Vision Health is opened Big public health problem.

The cause of disease and the pathological change of primary open angle glaucoma are understood the most completely.The angle of anterior chamber of this kind of glaucoma is open , for wide angle, its pathogenic factor may be by trabecular reticulum, Schlemm pipe, and the disease at three positions of aqueous veins return-flow system Becoming, causing aqueous humor to discharge SR increases.Its major lesions is as follows: the variation of (1) trabecular tissue: trabecular tissue hardening becomes Property, trabecular reticulum mesh reduces, and girder flaggy becomes irregular, even wrecks, and endotheliocyte increases, collagen fibril denaturing, Elastic fibers regression, trabecular meshwork gap turn narrow etc..(2) Schlemm pipe luminal stenosis or subside, inwall and trabecular reticulum group Knit obstruction collector tube proximal openings, form trabecular reticulum hernia, make Schlemm pipe and collector tube generation progressive atrophoderma inaccessible, make room Current output reduces.(3) venous pressure increases: a variety of causes, as periodicity sympatheticotonia, capillary tube venous pressure rise, Episcleral vein pressure rises high, causes aqueous humor and enters Venous resistance increase, and aqueous humor discharges difficulty.

In the technology of relevant effective diagnosis glaucoma conditions, there is techniques below problem: the degree of freedom of the conduit of use is poor, right The adaptability of microchannel pathological changes is strong, and during diagnosis, there is frictional resistance, it is impossible to realize to human body ophthalmic trabecular reticulum, The scanning imagery of the organs such as Schlemm pipe and collector tube.
