Embodiment Construction

[0022] Combine now figure 1 , figure 2 , image 3 , Figure 4 The present invention is further described, a method for reducing the concentration of VEGF in the eye, placing an inlet channel and an outlet channel for exchanging the vitreous cavity liquid at the corneoscleral limbus 3-4mm, changing and washing the liquid in the vitreous cavity through the inlet channel and the outlet channel, To reduce the concentration of VEGF in the vitreous cavity. The inlet channel and the outlet channel connect the outside of the eye with the inside of the vitreous cavity. The entrance channel and the exit channel are placed 3-4mm away from the corneoscleral limbus. The following devices can be used for vitreous cavity fluid exchange:

[0023] A device used in the method for reducing the concentration of VEGF in the eye, the device includes a ring structure, and the ring structure is made of flexible material. The lower surface of the ring structure is an arc structure similar to th...

Abstract

A method and device for reducing the concentration of VEGF in the eye. This device is used for measuring the concentration of VEGF by taking the liquid in the vitreous cavity after vitrectomy; Reduce the concentration of VEGF, prevent and treat a series of intraocular neovascular diseases secondary to various diseases such as diabetic retinopathy and retinal vein occlusion. The device can indwell the eyeball for a long time during the treatment of eye diseases, and take it out after all the intraocular treatments are finished.

Description

technical field [0001] The invention specifically relates to the technical field of ophthalmology, in particular to a method and device for reducing the concentration of VEGF in the eye. Background technique [0002] Intraocular neovascular disease is a kind of disease in which retinal ischemia and then retinal and iris neovascularization occur in various diseases such as proliferative diabetic retinopathy, retinal vein occlusion, retinal vasculitis, retinopathy of prematurity, Coats disease and trauma. Retinal neovascularization is prone to rupture due to the lack of normal vascular endothelial cells, leading to vitreous hemorrhage, fiber proliferation and tractive retinal detachment, which seriously affects vision. When the retinal ischemia is severe, new blood vessels appear in the iris to block the aqueous humor outflow channel, causing the intraocular pressure to rise, and neovascular glaucoma occurs. Neovascular glaucoma, loss of vision, eye pain due to high intraocul...
