Description

Eyeground inspection mirror

Technical Field

The present invention relates to a fundus oculi examination mirror, in particular to an indirect fundus oculi examination mirror for fundus retina examination.

Background

The fundus diseases are common and frequent diseases in ophthalmology, and comprise vitreous diseases, retina diseases, optic nerve diseases and the like. Fundus examination thus becomes a very important examination of ophthalmology.

Current fundus examination modalities include: direct ophthalmoscope, binocular indirect ophthalmoscope, fundus fluorescein angiography and the like. Especially, the binocular indirect ophthalmoscope is more and more applied in clinic due to strong stereoscopic impression and large magnification.

The binocular indirect ophthalmoscope applies the Gullstrand principle, 3 independent light paths (2 observation light paths and 1 illumination light path) simultaneously pass through the pupil of a patient, and because the distance between two eyes of an examiner is far larger than the observation light passing through the pupil of the patient, the indirect ophthalmoscope introduces a lens and a reflector system, and the separation angle of the observation light is narrowed, so that the observation is facilitated through the pupil. The examiner holds the front-mounted mirror for adjusting, magnifying and overturning the fundus for imaging, and places the fundus between the ophthalmoscope and the examiner to obtain a three-dimensional image of the retina.

Since the imaging of the indirect ophthalmoscope is clear on the premise that 3 independent light paths are on the same straight line, the front lens held by the examiner needs to be stable and the head lens and the pupil of the patient are kept on the same straight line, and the operation requirement of the examiner is high. And because the image formation of twice through eyepiece, objective forms the image of inversion magnification at last, and the image is observed and is not visual enough, and indirect ophthalmoscope need go on under the dim environment of light, and the operation is inconvenient.

Thus, there is a need for improvements in existing indirect ophthalmoscopes to better perform clinical fundus examinations.
