  • Patent number: 5714463
    Abstract: The intraocular use of combinations of stromal cell growth stimulators (e.g., TGF-.beta.) and antimetabolites (e.g., mitomycin C) in connection with glaucoma filtration surgery is described. The combination is applied to the surgical site to attract, mitogenically activate, and neutralize the potential for extracellular matrix synthesis leading to scar formation by stromal cells. Without such treatment, the formation of scar tissue may lead to impairment of the outflow of aqueous humor at the surgical site, particularly the fistula. The mitogenic activation of the stromal cells makes these cells susceptible to the anti-metabolites. This enables the antimetabolites to suppress the proliferation of the fibroblasts and other associated stromal cells to a much greater extent, relative to the proliferation seen when the metabolites alone are utilized.

  • Patent number: 5696091
    Abstract: The intraocular use of combinations of lens epithelial cell growth stimulators (e.g., TGF-.beta.) and antimetabolites (e.g., mitomycin C) is described. The combination is applied to the capsular bag to prevent or retard the formation of secondary cataracts following cataract surgery. The lens epithelial cell stimulators activate DNA synthesis in dormant lens epithelial cells, and thereby make those cells susceptible to the anti-metabolites. This enables the antimetabolites to suppress the proliferation of lens epithelial cells to a much greater extent, relative to the proliferation observed when the metabolites alone are utilized. The increased suppression of the growth of lens epithelial cells results in a significant improvement in the ability to prevent or retard the formation of opacities on the lens capsule (i.e., secondary cataracts).

  • Patent number: 5449671
    Abstract: The intraocular use of TGF-.beta..sub.3 in connection with glaucoma filtration surgery is described. A composition containing TGF-.beta..sub.3 is applied to the surgical site to suppress the production and/or alter the composition of extracellular matrix synthesized by fibroblasts at the surgical site, and thereby reduce the formation of scar tissue and consequent impairment of the outflow of aqueous humor through a fistula created during the surgery.

  • Patent number: 5411940
    Abstract: The use of TGF-.beta..sub.3 to reduce the formation of scar tissue as a result of trauma to the cornea of the eye is described. The invention is particularly directed to the use of TGF-.beta..sub.3 to reduce the formation of scar tissue in connection with ophthalmic surgical procedures involving the cornea, such as laser irradiation of the cornea. A composition containing TGF-.beta..sub.3 is applied to the site of the trauma to alter the production and composition of extracellular matrix synthesized by fibroblasts, and thereby reduce the formation of scar tissue and consequent impairment of vision.
