Embodiment Construction
[0067] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.
[0068] Such as figure 2 , Figure 7a , Figure 7b , Figure 7c As shown, the artificial vitreous body device suitable for children with ocular-cerebral-renal syndrome of the present invention includes:
[0069] Silicone rubber membrane 1, also known as microelastic membrane, is in the shape of a film. The thickness of a simple film is 20 μm, which exceeds the thickness of a conventional artificial vitreous body (10 μm). The period of use shall not be less than 5 years. The silicone rubber membrane 1 has a port filled with silicone oil and an internal closed space connected to the port. The silicone rubber membrane is film-like when unfolded into a plane, and becomes a three-dimensional spherical or apple-like shape after being filled with silicone oil;

The invention provides an artificial vitreous body device suitable for a child suffering from the oculocerebrorenal syndrome. The artificial vitreous body device suitable for the child suffering fromthe oculocerebrorenal syndrome comprises a silicone rubber membrane, a metal wire mesh, a valve and an auxiliary tube, wherein the silicone rubber membrane is provided with a port filled with siliconeoil and an internally closed space connected with the port, and the silicone rubber membrane is membrane-shaped when being unfolded into a plane and is ball-shaped after being filled with the silicone oil; the metal wire mesh is poured in the inner wall of the silicone rubber membrane, the metal wire mesh comprises a first metal wire arranged in the direction perpendicular to the eye axis and a second metal wire arranged in the direction of the eye axis, and the first metal wire and the second metal wire intersect to form a grid shape; the valve is arranged at the port of the silicone rubbermembrane, and the valve is provided with a through hole that is through and a side wall surrounding the through hole; the through hole communicates with the internally closed space, and the side wallsurrounding the through hole is provided with an elastic sealing surface; and the auxiliary tube is arranged in the valve in a translational manner. The phenomena of enophthalmos and the like of an artificial vitreous body are avoided.
Description
technical field [0001] The invention relates to the field of ophthalmic medical devices, in particular to an artificial vitreous body device suitable for children with ocular-cerebral-renal syndrome. Background technique [0002] Oculo-cerebral-renal syndrome, also known as Lowe syndrome, is a rare sex-linked recessive genetic disease. Clinically, it is characterized by congenital cataracts, mental retardation, and renal tubular acidosis. Defects exist at birth, but symptoms mostly appear in infancy or later. Eye, brain, and kidney lesions can also appear at different ages. [0003] The ocular symptoms of Lowe syndrome include: congenital bilateral cataract, accompanied by congenital glaucoma; vitreous opacity, severe visual impairment, only light perception or total blindness; coarse nystagmus and photophobia are often present. [0004] Lowe syndrome can be divided into infancy, childhood and adulthood according to the natural history. In infancy, it is characterized by ...
