Structure of modulating intraocular pressure on glaucoma
A 3D porous structure is designed for modulating intraocular pressure on glaucoma. The 3D porous structure includes collagen and glycosaminoglycan in the form of copolymer, wherein the collagen and the glycosaminoglycan have a 10:1 ratio in weight and the copolymer has a percentage in the range of 0.125% to 8%.
1 . A structure of modulating intraocular pressure on glaucoma, comprising collagen and glycosaminoglycan in the form of copolymer, wherein said collagen and said glycosaminoglycan have a 10:1 ratio in weight and said copolymer has a percentage in the range of 0.125% to 8%.
2 . The structure of modulating intraocular pressure on glaucoma as claimed in claim 1 , wherein said collagen comprises type I collagen.
3 . The structure of modulating intraocular pressure on glaucoma as claimed in claim 1 , wherein said glucosaminoglycan comprises chondroitin-6-sulfate, chondrotin-4-sulfate, heparin, heparan sulfate, keratan sulfate, dermatan sulfate, chitin or chitosan.
4 . The structure of modulating intraocular pressure on glaucoma as claimed in claim 1 , wherein said copolymer is prepared by the steps of:
(a) dissolving said collagen and said glycosaminoglycan in acetic acid to form a mixture;
(b) drying said mixture to form a sheet;
(c) employing heat treatment on said sheet; and
(d) ultraviolet irradiating said sheet.
