Problems solved by technology

Existing slit lamps have complex mechanical structures, need to manually move the light source and observation direction, and are inconvenient to adjust and operate, and require professionally trained doctors to operate, so the use is limited
[0007] Moreover, the mechanical structure of the current slit lamp moves slowly, requiring the patient's head to be fixed on the jaw frame of the slit lamp, and the patient's eyeballs must not move as much as possible to see the lesion clearly
Since the human eye naturally has a saccade movement, it is easy to move the position, and the inspection is time-consuming and laborious. Therefore, the patient needs repeated exchanges and cooperation with experienced doctors to complete the inspection, especially for children and infants. not suitable for remote operation

Embodiment Construction

[0029] The ophthalmic examination apparatus of the present invention includes a light source 100 , a light field camera 200 and a processing device 300 . The light source 100 can be controlled to generate a desired light field for illuminating the eye to be examined. The light field camera 200 is configured to simultaneously receive imaging data of the entire eyeball illuminated by the light field. The processing device 300 is configured to process the received imaging data.

[0030] The ophthalmic examination equipment of the present invention uses the light source 100 to replace the traditional slit lamp, uses the light field camera 200 to simultaneously receive the imaging data of the entire eyeball illuminated by the light field, and uses the processing device 300 to process the received imaging data, thereby Analysis of the received imaging data can be accomplished remotely.

[0031] figure 1 is a schematic diagram of the 4D parameterization of the light field. A ligh...

Abstract

The invention relates to a device and a method for ophthalmic examination. The device for ophthalmic examination comprises a light source, a light-field camera, and a processing device. The light source can be controlled to be an expected light field, and the light field is used to light a to-be-examined eyeball. The light-field camera is configured to receive imaging data of the whole eyeball after being illuminated by the light field. The processing device is configured to process the received imaging data.

Description

technical field [0001] The present invention relates to ophthalmic examination apparatus and methods, and more particularly to ophthalmic examination apparatus and methods utilizing light field technology. Background technique [0002] Slit lamp microscope is an essential and important instrument for eye examination. The slit lamp microscope is composed of an illumination system and a binocular microscope. It can not only observe superficial lesions very clearly, but also can adjust the focus and the width of the light source to make an "optical section" so that lesions in deep tissues can also be clearly displayed. . [0003] Examination of ophthalmic diseases requires examination with a slit-lamp microscope. The doctor needs to use the optical section to observe the normal and diseased tissue on the surface and inside of the patient's eyeball to distinguish the location and level of the lesion, so as to determine the location of the lesion, and when observing the patient...
