Abstract

The invention relates to a method and device for reducing the intraocular VEGF concentration. The device is used for measuring the VEGF concentration by taking vitreous cavity liquid after the vitrectomy; when the intraocular VEGF concentration is increased, the device is also used for changing and washing the vitreous cavity liquid to reduce the VEGF concentration to prevent and treat a series ofintraocular neovascular diseases secondary to various diseases such as diabetic retinopathy, retinal vein occlusion and the like. The device can be retained in eyeballs for a long time during the treatment of eye diseases, and be taken out after the end of the intraocular treatment.

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...
