title: The visual field after trabeculectomy. A follow-up study using computerized perimetry.
abstract: Series of visual fields in 20 eyes in which trabeculectomy had been performed were studied retrospectively. Computerized perimetry was used and the condition of the visual field was summarized into single numbers. Regression analysis was applied to series of such performance numbers. No correlation was found between the regression coefficient and the mean post-operative pressure or the mean pressure reduction. A dependence of the regression coefficient on the size of the visual field defect was observed.
