Preoperative tranilast as adjunctive therapy to primary pterygium surgery with a 1-year follow-up.

Purpose: To determine the efficacy of tranilast as an adjunctive therapy in conjunctival autograft.

Methods: Twenty-nine patients were randomly allocated to the Tranilast Group (n=15) or the Control Group (n=14). The Tranilast Group received a subconjunctival injection of 0.

Portable light transmission measuring system for preserved corneas.

Background: The authors have developed a small portable device for the objective measurement of the transparency of corneas stored in preservative medium, for use by eye banks in evaluation prior to transplantation.

Methods: The optical system consists of a white light, lenses, and pinholes that collimate the white light beams and illuminate the cornea in its preservative medium, and an optical filter (400-700 nm) that selects the range of the wavelength of interest. A sensor detects the light that passes through the cornea, and the average corneal transparency is displayed.
