  • THE RELATION BETWEEN VISUAL SENSITIVITY AND INTRAOCULAR-PRESSURE IN NORMAL EYES INVESTIGATIVE OPHTHALMOLOGY & VISUAL SCIENCE Tyler, C. W., Ryu, S., Stamper, R. 1984; 25 (1): 103-105

    Abstract

    Intraocular pressure and flicker modulation sensitivity at 25 and 40 Hz were measured in 22 normal observers, with an age range from 20-71 years. Significant correlations up to 0.67 were found between intraocular pressure and flicker sensitivity at several points in the visual field. There was no correlation between flicker sensitivity and age of the observers. Thus intraocular pressure may affect neuronal function in the normal eye.

  • EVALUATION OF TUMOR ANGIOGENESIS FACTOR WITH THE RABBIT CORNEA MODEL INVESTIGATIVE OPHTHALMOLOGY & VISUAL SCIENCE Ryu, S., Albert, D. M. 1979; 18 (8): 831-841

    Abstract

    Sequential histopathological observations were made of the rabbit corneas after an implantation of viable and nonviable tumor cells in the corneal stroma. They showed a nonspecific localized interstitial keratitis accompanied by inflammatory cells and new capillaries. We could not observe any significant clinical or histopathological differences between the corneas containing live or dead tumor implants, or between those with different tumor types (i.e., retinoblastoma and melanoma). Some variation in the severity of the inflammatory response was observed in different animals with the same tumor. In all cases, the extent of the corneal neovascularization correlated with the degree of inflammation. However, in rabbits made immune-deficient by radiation, there was negligible inflammation and vascularization when tumor was implanted.
