Description

Head-mounted intraocular pressure measuring instrument and cloud platform
Technical Field
The invention relates to the technical field of medical instruments, in particular to a head-mounted intraocular pressure measuring instrument and a cloud platform.
Background
Glaucoma is an eye disease characterized by atrophy and depression of optic papilla, visual field loss and visual deterioration, and has become the first irreversible blindness disease in the world. Pathological increased intraocular pressure is an important risk factor, and selective, progressive death of Retinal Ganglion Cells (RGCs) is the ultimate outcome of all forms of glaucoma.
Currently, no clinically effective treatment for repair or reversal of damaged RGCs is available, and since intraocular pressure is a central element of clinical glaucoma diagnosis, it is necessary to control the risk factor of intraocular pressure increase as much as possible to prevent and diagnose glaucoma. The intraocular pressure of human is not constant for 24 hours and can be changed at any time like blood pressure, the pathological intraocular pressure is beyond the pressure that RGCs can bear, the pathological intraocular pressure value of each person is different, although the intraocular pressure range of most people is 10mmHg-21mmHg, the pathological intraocular pressure is only a statistical category, each glaucoma patient has own target intraocular pressure (the target intraocular pressure is the highest value that RGCs can not die any more), and the intraocular pressure is reduced to be below the target intraocular pressure according to the individual disease condition of the patient to ensure that retinal ganglion cells can not die any more, so the monitoring of the intraocular pressure is very important. The single intraocular pressure measured when a patient visits a hospital cannot reflect the intraocular pressure fluctuation condition of the patient, and doctors cannot give a personalized treatment scheme according to the time point of intraocular pressure peak appearance in 24 hours of the patient.
Alterations in retinal hemodynamics are associated with many ocular and systemic diseases (including glaucoma, hypertension, diabetes, etc.), and intraocular pressure is uniformly applied directly to the retina, so intraocular pressure has a direct effect on the dynamics of retinal blood flow, blood flow velocity, etc. of the vessels. Clinical trials have found that retinal and retrobulbar blood flow, velocity, decreases as ocular pressure increases.
The existing instrument for measuring intraocular pressure mainly applies certain pressure to the cornea of a human eye in a contact or non-contact mode, measures and converts a corneal deformation parameter, and obtains a numerical value of the intraocular pressure. If the principle is used for home intraocular pressure measuring equipment, the cornea can be directly or indirectly contacted, under the condition of no guidance and supervision of a clinician, the cornea and even the eyeball can be irreversibly damaged by any careless operation, the safety cannot be ensured, and the popularization is difficult.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples of the specification.
The inventor finds that the reduction of the intraocular pressure can obviously increase the capillary perfusion of the annular papillary area of the retina nerve fiber layer through a large number of clinical tests. The intraocular pressure is 35-42 mmHg when the eye pressure is not treated, and the intraocular pressure is reduced to 12-18 mmHg (the intraocular pressure is reduced by more than 50% in all cases) after the intraocular pressure is reduced through treatment and the capillary vessel perfusion of the annular papillary area of the retinal nerve fiber layer is obviously increased; for young people with untreated high intraocular pressure, after intraocular pressure is reduced through treatment, capillary perfusion of the annular papillary area of the retinal nerve fiber layer is remarkably increased, and the increase of the vascular perfusion influences the diameter of blood vessels and blood flow, so that the capillary perfusion can be effectively reflected by collecting the diameter of the retinal capillary and the number of red blood cells passing through the cross section of the retinal capillary in unit time, and the intraocular pressure is indirectly reflected.
The intraocular pressure is indirectly determined through the retinal capillary parameters, a database of correlation between the retinal capillary parameters and the intraocular pressure and the blood pressure is required to be established, then a measured person measures the diameter of the retinal capillary and the number of red blood cells passing through the cross section of the retinal capillary in unit time in real time, and finally the most approximate intraocular pressure value is obtained by comparing the measured person with the correlation database.

4. and analyzing the parameters of each grade of blood vessels of the retina and the correlation between the flow speed and the flow of the blood in each grade of blood vessels of the retina to obtain the relation between the diameter of the blood vessels and the flow speed of the blood flow in the graph 1 and the relation between the diameter of the blood vessels and the flow of the blood flow in the graph 2.
Secondly, determining the correlation data of the retinal blood vessel parameters with the intraocular pressure and the blood pressure:
1. collecting data of non-glaucoma patients (NG group) and glaucoma patients (G group), and recording epidemiological data (information such as sex, age, weight, height, etc.) and general conditions (whether patients have diabetes, hypertension or other diseases affecting small blood vessels of the whole body, and whether patients have smoking and drinking histories);
2. using OCTA technology to collect the diameter of each blood vessel of retina and the number of red blood cells passing through the cross section of capillary blood vessel in unit time;
3. monitoring the intraocular pressure of the NG group and the intraocular pressure of the G group in real time by using a non-contact tonometer and an applanation tonometer, and simultaneously monitoring the blood pressure of a measured person;
4. and analyzing the correlation data of the retinal vascular parameters and the intraocular pressure obtained by the OCTA technology of the NG group and the G group of people, and analyzing the correlation data of the retinal vascular parameters and the blood pressure obtained by the OCTA technology of the NG group and the G group of people.
