45 results about "Aqueous humour" patented technology

The present disclosure describes an optical probe for applying a laser light to at least the flat portion of the ciliary body and optionally other areas, such as the trabecular mesh, the ciliary crown and / or the ciliary sulcus of the eye, the present invention relates to methods, such as for treating glaucoma, reducing intraocular pressure (IOP), improving the outflow of aqueous humor from the eye, and / or reducing the accumulation of aqueous humor within the eye. The optical probe may be adapted for simultaneous treatment of a plurality of different regions, tissues, or eye bodies of the eye, or for sequential treatment of a plurality of different regions, tissues, or eye bodies of the eye.

The application discloses a teaching simulative human eyeball aqueous humor circulation model in the technical field of eyeball aqueous humor circulation models, which comprises a model box, an eyeball model assembly arranged in the model box, a functional body arranged at the top of the model box and a pump assembly arranged in the functional body. The eyeball model assembly comprises an eyeball wall, an eyeball and an optic nerve, and the eyeball wall is provided with a cornea at the front end. An iris is arranged on the side of the cornea close to the eyeball, the space between the cornea and the iris is an anterior chamber, the included angle between the cornea and the iris is an anterior chamber angle, the center of the iris is provided with a pupil, the iris is provided with a lens on the side close to the eyeball, the lens is provided with a zonular ligament around the lens, and the other end of the zonular ligament is fixedly connected with a ciliary body. The space between the iris and the lens constitutes a posterior chamber. The application has the advantages of simple structure, simulation of the process that the aqueous humor is retained in the eye to press the optic nerve when the anterior chamber angle is closed or the aqueous humor outflow passage is blocked, and convenience for medical students to understand the process that the optic nerve is pressed by the increased intraocular pressure when the aqueous humor passage is blocked.
