Abstract

The invention relates to a device for measuring intraocular pressure, in particular to a device for measuring the intraocular pressure based on optical coherence elastography. The device for measuring the intraocular pressure based on the optical coherence elastography has the advantages that the measurement precision is high, the deformation of eyes can be refracted to an elastography photo when gas is sprayed to the eyes, and accurate data of the intraocular pressure can be more intuitively seen. The device for measuring the intraocular pressure based on the optical coherence elastography comprises bottom feet and a fixing frame, the bottom feet are arranged at the four corners of the bottom of the fixing frame, and the fixing frame is of a left-right hollow structure. Through the principle of elastography, information refracted by the eyes is converted into a visible light image, namely an imaging picture, which is habitual to a doctor, then a broadband light source is refracted to the imaging picture, and the visible light image and the imaging picture are overlapped, so that the doctor can judge an intraocular pressure result through the imaging picture.

Description

technical field [0001] The invention relates to a device for measuring intraocular pressure, in particular to a device for measuring intraocular pressure based on optical coherence elastography. Background technique [0002] Intraocular pressure refers to the pressure of the contents of the eyeball on the wall of the eyeball. It is an important parameter that can be quantitatively controlled in the treatment of glaucoma. It plays an important role in the diagnosis of glaucoma. Generally, a non-contact tonometer is used for measurement. The pulse force injects the gas to the central part of the cornea, and the impact of the gas on the eye deforms the eye, and then measures the size of the intraocular pressure. When checking with a non-contact tonometer, record the time of the gas injection and convert it into intraocular pressure This calculation is rough and the precision is low. [0003] Therefore, in order to solve the above problems, we are now developing a method that c...
