  • Patent number: 11426361
    Abstract: A method for treatment of irritation or damage to corneal or conjunctival epithelial cells, particularly for irritation or damage to corneal or conjunctival epithelial cells due to severe Sjögren's syndrome, comprising applying topically to an affected eye an aqueous solution of glycerol characterized by a glycerol concentration of >1% (w/v), most preferably 2.5% (w/v). The method is effective even in the case of very low tear formation, and its effectiveness cannot be explained by the known humectant effect of glycerol.

  • Patent number: 5037010
    Abstract: A dispensing container for a viscous substance comprising a sleeve defining an axis of rotation and having a pair of ends arranged at first and second locations along the axis, the sleeve further defining a helical travel path on an inward facing surface thereof. A dispensing member mounted in association with one of the pair of ends of the sleeve, and, a piston head mounted within the sleeve and defining an outward facing peripheral surface operative to cooperate with the helical travel path and further defining with the dispensing member and a portion of the sleeve extending therebetween a storage volume for the viscous substance. The piston head travels along the axis of rotation when undergoing rotation thereabout relative to the sleeve, a linkage apparatus is integrally formed with the piston head and defining an end portion associated with a predetermined portion of the sleeve.
