Description

An easily adjustable examination table for ophthalmology

technical field

The invention relates to an examination table for ophthalmology, in particular to an easily adjustable inspection table for ophthalmology.

Background technique

The full name of ophthalmology is "eye disease specialist". Ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. In 1851, Helmholtz in Germany invented the ophthalmoscope, and ophthalmology became a truly independent discipline. Doctors who can engage in ophthalmology need graduates of this major, and they must be able to engage in ophthalmology professional studies in tertiary hospitals and higher medical colleges before they can conduct clinical medical treatment and teaching work. Common ophthalmic diseases include: central serous retinopathy, dry eye syndrome , sympathetic ophthalmia, night blindness, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, heterochromia, retinitis pigmentosa, central retinal artery occlusion, retinal detachment, myopia, hyperopia, Needle eye, snow blindness, chalazion, glaucoma, floaters, etc. General eye examination, including ocular appendages and anterior segment examination, ocular adnexa examination includes: eyelid, conjunctiva, lacrimal apparatus, eyeball position and orbital examination; eyeball Anterior segment examination: including examination of cornea, anterior segment of sclera, anterior chamber, iris, pupil, and lens. Commonly used equipment in ophthalmology includes eye chart, tonometer, slit lamp, direct/strip retinoscopy mirror, color vision test table, perimetry , film reading lamp, A/B ultrasonic examination instrument, refractometer, keratometer, fluorescein fundus imaging machine, ophthalmic retrobulbar injection needle, lacrimal duct irrigation needle, eyelash extraction forceps, retinal photocoagulation laser equipment, retina cryograph, Operating table, operating lamp, conventional external eye surgery instruments, operating microscope, microsurgical instruments, intraocular electromagnet.
