  • Publication number: 20080008698
    Abstract: A non-surgical method for preventing or reducing the rate of the progression of non-proliferative diabetic retinopathy to the proliferative form of diabetic retinopathy comprising intravitreally administering to a patient suffering from non-proliferative diabetic retinopathy an effective amount of serine proteinase enzyme sufficient to create, without surgery, a posterior vitreal detachment to prevent or reduce the progression of proliferative diabetic retinopathy is said patient. Also disclosed is a non-surgical method of treating ocular conditions such as retinal ischemia, retinal inflammation, retinal edema tractional retinal detachment, tractional retinopathy, vitreous hemorrhage and tractional maculopathy by intravitreally administering to a patient suffering from one or more of these conditions with an effective amount of a serine proteinase enzyme to reduce or treat that particular ocular condition.

  • Publication number: 20070093461
    Abstract: This invention relates to the effect of Loteprednol etabonate on vascular dysfunction in the back of the eye. More specifically, this invention relates to methods of modifying a pathogenic angiogenesis in the back of an eye of a patient, the method comprising administering to a patient in need thereof a pathogenic angiogenesis modifying amount of Loteprednol etabonate. Moreover, this invention relates to methods of modifying pathologic vascular permeability manifested as retinal edema. The method compromises administering to a patient an amount of LE sufficient to reduce retinal edema.

  • Publication number: 20070049559
    Abstract: Preparations for controlling intraocular pressure in the eye comprise as an active compound, arylazine substituted with a carbonylic moiety, which compound is capable of effecting a “pharmacological trabeculocanalotomy” in an eye by means of reducing juxtacanalicular meshwork to promote outflow of aqueous. The organic active compound increases Gelatinase A activity in ocular cells by increasing cell membrane expression of membrane-type matrix metalloproteinases (MT-MMPs) to increase aqueous outflow as a treatment for glaucoma, e.g., primary open angle glaucoma.

  • Patent number: 6973590
    Abstract: A stack frame associated with a procedure that can alter or affect a shared resource where the procedure is associated with a child stack and is declared by a parent stack is marked isolated. Isolated stack frames are allotted an additional predefined interval of processing time before commands such as terminate and interrupt applied to the child stack are executed. If the command is a terminate command, after the additional allotted time interval has passed, both child and parent stacks are terminated. If the command is an interrupt command, after the additional allotted time interval has passed, the child stack is interrupted. If the command is a resource-terminated command, an operator is permitted to allocate more resource time to the task or may terminate both parent and child stacks. If a parent stack is terminated, all child stacks of the parent are terminated.
