Viscoelastic substances, widely used in anterior ocular surgery, sodium hyaluronate (Healon®) and hydroxypropylmethylcellulose, show a protective...

...Peep Algvere; Irène M. Landau To determine whether or not sodium hyaluronate (NaHA) has any inhibitory effect on cellular proliferation in the vitreous space, we implanted 3 × 105 or 1 × 106 homologous fibroblasts into the vitreous cavity of 21 vitrectomized albino rabbits. Sixteen eyes received...

...Linda D. Hazlett; Ronald Barrett The association with time (0–60 min) of an eye drop preparation containing sodium hyaluronate with the corneal epithelial cell surface was examined using both cryo-fixation and osmium tetroxide vapor fixation and scanning (SEM) and transmission electron microscopy...

...Rainer N. Mittl; Ram Tiwari Various fractions of sodium hyaluronate were injected into the suprachoroidal space of rabbit eyes via the pars plana as ‘internal’ buckles. The areas of elevated choroid were diffuse, usually extending over approximately one quadrant. The buckling effect was short-lived...

...H.D. Gnad Vitrectomy was performed on 48 rabbit eyes. Refilling of the vitreous cavity with Ringer’s solution or sodium hyaluronate gave biomicroscopically equivalent results. Injection of sodium hyaluronate or Ringer’s solution causes coarsening of the fibrillary vitreous structure with numerous...

... on hydroxypropylmethylcellulose, sodium hyaluronate, sodium polyacrylate or tamarind gum. The latter polymer showed the best overall results. Ferning tests on the formulations were also performed: their validity as predictors of the efficacy of tear substitutes is discussed. Original Paper Ophthalmic Res 1999;31:229 235 Received...
