Method and ophthalmic equipment for measuring human exophthalmos degree by using ophthalmic equipment

Abstract

The invention discloses a method utilizing ophthalmology equipment for detecting the exophthalmic degree and ophthalmology equipment. The method comprises the steps that the first distance X1 from a system reference point St of the ophthalmology equipment to the eye outer side frame edge Ek in the front and back direction, the second distance X2 from a system probe of the ophthalmology equipment to the system reference point St in the front and back direction, and the third distance X3 from the corneal vertex Ec to the system probe in the front and back direction are obtained, and the exophthalmic degree is obtained according to an equation Delta=X1+X2-X3; the ophthalmology equipment mainly comprises the system probe, a cornea position locating module, an eye outer side frame edge locating device and an eye outer side frame edge locating device connecting mechanism. A primary optical axis of the system probe is aligned to the corneal vertex Ec. The cornea position locating module is used for locating the corneal vertex Ec and measuring the third distance X3 from the corneal vertex Ec to the system probe. The eye outer side frame edge locating device is used for imaging the eye outer side frame edge. According to the method and the equipment, the exophthalmic degree is detected through a non-contact mode, and cross infection is avoided.

Description

technical field

[0001] The invention belongs to the detection field of human exophthalmos, and in particular relates to a method for measuring human exophthalmos by using ophthalmic equipment and the ophthalmic equipment. Background technique

[0002] Exophthalmos is usually divided into the following conditions: orbital tissue edema and lymphatic infiltration in hyperthyroidism can cause unilateral or bilateral exophthalmos; sudden unilateral exophthalmos is usually due to hemorrhage or inflammation of the orbit or paranasal sinuses Arteriovenous aneurysms of the internal carotid artery and cavernous sinus can cause pulsatile exophthalmos with murmurs; post-traumatic ones may be due to carotid-cavernous sinus fistula, confirmed by ocular auscultation; trauma or infection (especially face) can cause cavernous sinus thrombosis with unilateral exophthalmos and fever; unilateral high myopia or meningioma can cause unilateral exophthalmos.
