Panretinal optical function imaging system

Abstract

The invention discloses a panretinal optical function imaging system comprising a stimulation light source and an optical element part thereof, an infrared illumination light source and an optical element part thereof, a double-ellipsoid optical element part and a retinal infrared image signal processing part, wherein the double-ellipsoid optical element part comprises a transverse ellipsoid reflector and a longitudinal ellipsoid reflector; one focal point of the longitudinal ellipsoid reflector and an eyeball node intersect at a point F3; the other focal point of the longitudinal ellipsoid reflector coincides with one external focal point F2 of the transverse ellipsoid reflector; the connection line of the external focal point F2 of the transverse ellipsoid reflector and the focal point F3 of the longitudinal ellipsoid reflector forms a rotation axis; and the optical elements of the whole optical imaging system rotates around the rotation axis Z. The panretinal optical function imaging system has the advantages of high scanning efficiency, short time, low image noise and high resolution, the functions of different kinds of photoreceptors can be detected and distinguished, and interference generated by the environment and electronic instruments can be reduced. The panretinal optical function imaging system can be used for objectively detecting the panretinal function of eyes without causing wounds in the clinic of ophthalmology.

Description

technical field [0001] The invention relates to a non-invasive detection device for objective clinical detection of retinal function in ophthalmology. Background technique [0002] Modern ophthalmological examination technology provides a powerful tool for doctors to diagnose eye diseases. Broadly speaking, ophthalmology-related examinations include two categories: morphological examination and functional examination. The former includes fundus color photography, fundus fluorescein angiography, optical coherence tomography (OCT), eye B-ultrasound, Pentacam anterior segment analyzer, IOL MASTER anterior segment analyzer, etc.; the latter includes visual acuity, visual field, ocular electrophysiological examination, etc. With the development of science and technology, ophthalmology-related morphological examination techniques are changing with each passing day: color fundus photography can collect retinal color images; the extensive development of fundus fluorescein angiograp...

Problems solved by technology

In recent years, the emergence of multifocal electrophysiological examination techniques (including multifocal electroretinogram and multifocal visual evoked potential) has enabled ophthalmologists to judge the functions of different regions of the retina and / or optic nerve and visual cortex. However, based on electrophysiological The function checking technique of the present method has the disadvantages of the following aspects: 1) Poor intuition

Since brain tissue cannot be exposed without craniotomy, brain optical imaging technology can only be used for animal experiments, and cannot be used for retinal functional imaging detection
