Description

Suprachoroidal space pressurizing balloon in high myopia macular region and implanting device thereof

Technical Field

The invention relates to the technical field of ophthalmology, in particular to a suprachoroidal space pressurizing balloon in a high myopia macular region and an implanting device thereof.

Background

High myopia macular degeneration such as macular hole, macular retinal detachment and the like is one of the main causes of blindness at present, and the current treatment methods include vitrectomy, posterior scleral compression (reinforcement) surgery and the like. Vitreous surgery is a procedure in which vitreous traction is removed and the inner limiting membrane is removed to promote the amelioration of macular degeneration, and posterior scleral compression (reinforcement) is a procedure in which compression is performed from behind the sclera to promote the amelioration of macular degeneration. The vitreous resection operation cannot prevent the growth of the axis of the eye, the postoperative lesion may recur, and some lesions cannot be solved by the vitreous resection operation alone. Posterior scleral compression (reinforcement) surgery has problems of lack of compression materials, unstable effect, complications, and the like. The suprachoroidal hyaluronic acid injection is a method for rhegmatogenous retinal detachment, in which hyaluronic acid is injected into the suprachoroidal space at the site of the peripheral fissure, forming a compression ridge, thus acting as a therapeutic agent, and is currently used in a relatively small number. Aiming at the defects of a vitrectomy operation and a posterior sclera pressurization (reinforcement) operation, the invention designs a suprachoroidal space pressurization balloon in a high-myopia macular region and an implantation device thereof, and the purposes of shortening the axis of the eye and treating macular degeneration are achieved by jacking from the suprachoroidal space.
