According to the glaucoma simulation glasses and the manufacturing method thereof, through the arrangement of the opaque regions on the lenses, defects appear in visual fields, thereby providing a tool, which is produced and used conveniently, for glaucoma visual field defect simulation in teaching process.
Description
Technical field
The present invention relates to a kind of medical teaching and diagnosis aid, relate in particular to glaucomatous glasses of a kind of simulation and preparation method thereof.
Background technology
Glaucoma, be a kind ofly fall ill rapidly, harmfulness causes blind common difficult illness in eye greatly, at any time, belongs to eyes venereal disease and becomes, can fall ill by eyes, or a glance onset simultaneously, secondary blindness.The glaucomatous cause of disease is: the liquid circulating in anterior chamber and back room (aqueous humor), constantly generate and discharge, so that intraocular pressure maintains stable level, once aqueous humor passing away (angle, room) blocks, aqueous humor is discharged and is obstructed, and intraocular pressure increases, and causes that wall of eyeball pressure increases, cause optic nerve injury, thereby cause defect of visual field.
Perimetry has important value to glaucomatous diagnosis, because it has represented the damage of optic nerve, but early stage slight defect of visual field is difficult to find conventionally, until area of visual field only remains the scope less than 20%, because glaucoma is a kind of irreversible blinding disease, therefore, take effective means that people are understood and realize glaucomatous evolution, being conducive to people and diagnosing timely and find glaucoma.
Glaucoma is second-biggest-in-the-world blinding illness in eye, also be one of Focal point and difficult point in research of ophthalmology teaching, in the middle of medical teaching, mostly can only to student, explain glaucomatous relevant knowledge from pathology equal angles at present, student can not personal understanding to the real state of glaucoma patient defect of visual field, therefore, simply, from the cause of disease, pathology, clinical manifestation and principle of reatment, explain abstractively, medico for just involving in clinical Theory Course study, is sometimes difficult to clarify and may misleads.Therefore, take effective method to help the glaucomatous pathological change of student's correct understanding and evolution, have very important significance.
