  • Publication number: 20100204244
    Abstract: Agents that stimulate nuclear translocation of Nrf2 protein and the subsequent increases in gene products that detoxify and eliminate cytotoxic metabolites are provided in a method for treating diabetic retinopathy or drusen formation in age-related macular degeneration. The structurally diverse agents that act on the Nrf2/ARE pathway induce the expression of enzymes and proteins that possess chemically versatile cytoprotective properties and are a defense against toxic metabolites and xenobiotics. Agents include certain electrophiles and oxidants such as a Michael Addition acceptor, diphenol, thiocarbamate, quinone, 1,2-dithiole-3-thione, butylated hydroxyanisole, flavonoid other than genistein, an isothiocyanate, 3,5-di-tert-butyl-4-hydroxytoluene, ethoxyquin, a coumarin, combinations thereof, or a pharmacologically active derivative or analog thereof.

  • Patent number: 7764370
    Abstract: Embodiments of the present invention provide a system and method for determining the location of the bottom of a fluid chamber in a surgical cassette to calibrate the surgical system. According to one embodiment, the surgical cassette is shaped to allow light from a light source to pass unobstructed to a linear sensor array in an area that is a known distance from the bottom of a fluid chamber. Light rays intersected by solid cassette material, on the other hand, will insufficiently illuminate the linear sensor array. Because the slot is a known distance from the bottom of the chamber, the location of the bottom of the chamber can be determined by determining the transition between illuminated and insufficiently illuminated portions of the linear sensor array.

  • Patent number: 7762981
    Abstract: An ophthalmic injection device has a dispensing chamber housing, a plunger, an actuator for driving the plunger, a temperature control device, and a temperature release mechanism. The dispensing chamber housing has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The temperature control device at least partially surrounds the dispensing chamber housing and is capable of altering the temperature of the substance in the dispensing chamber. The temperature release mechanism is in a locked position when the substance is outside the proper temperature range and an unlocked position when the substance is in the proper temperature range.

  • Patent number: 7762978
    Abstract: An infusion sleeve of an ultrasonic vibrating needle. The sleeve is collapsible and serrated or scalloped at a distal end. Fluid flows through a passage between the needle and the infusion sleeve in a direction from the proximal end of the sleeve to a distal end of the sleeve. Upon reaching the distal end, the fluid emerges by flowing across valley formations that are between peak formations of the distal end of the infusion sleeve. The peak formations abut the exterior of the incision so that the fluid flow cools tissue at the incision and the needle.

  • Publication number: 20100183629
    Abstract: Antagonists of S1P3 (Edg-3) receptors are provided for attenuation of Smad signaling in a method of down-regulation of receptor signaling and downstream decreased production of connective tissue growth factor in ocular disorders involving CTGF accumulation. Ocular disorders involving inappropriate CTGF accumulation include ocular hypertension, glaucoma, glaucomatous retinopathy, optic neuropathy, macular degeneration, diabetic retinopathy, choroidal neovascularization, proliferative vitreoretinopathy and ocular wound healing, for example. Such disorders are treated by administering antagonists of the present invention.

  • Patent number: 7760411
    Abstract: Generally speaking, the output brightness of an illuminator is varied by chopping an output light beam such that the beam is alternately interrupted and unhindered. An interrupter can be rapidly moved into and out of the transmission path of a light beam. The brightness of the light beam received at a site will be attenuated based on the amount of time per cycle the light beam remains obstructed versus unhindered.

  • Patent number: 7758538
    Abstract: A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines a temperature of an eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.
