A method to quantify different glaucomatous visual field defects is presented. Three visual field indices are calculated: the short-term fluctuation, the mean defect, and the corrected loss variation. The method was applied to visual fields tested with program JO on the Octopus automated perimeter. The indices of 130 glaucoma suspects and 50 glaucoma(More)
Experience with a number of visual fields has shown that the algorithm used earlier for estimating general depression in glaucomatous visual fields was too conservative. A new, more sophisticated algorithm for calculating diffuse loss has been devised and the results obtained in the evaluation of 20 glaucomatous visual fields were compared with those(More)
The coefficients of internal consistency and retest reliability had been rarely investigated within the methodology of dream content analysis. Analyzing a dream series of elderly, healthy persons obtained from weekly telephone interviews, the internal consistency of a series of 20 dreams and retests after 4 or 22 weeks, respectively, had been computed. The(More)
Two visual field indices, the mean defect (MD) of Flammer and the mean deviation (MD) of Heijl, have found wide acceptance among perimetrists. We compared these indices in 169 visual fields from normal- and high-tension glaucomatous eyes. Visual field damage in these eyes varied from slight to severe. In computations of the mean deviation index, the(More)
Nonverbal behaviors play an important role in communication for both humans and social robots. However, hiring trained roboticists and animators to individually animate every possible piece of dialogue is time consuming and does not scale well. This has motivated previous researchers to develop automated systems for inserting appropriate nonverbal behaviors(More)
While there have been several studies about dreams and dreaming among the elderly, there does not seem to have been any study of the effects of regular dream-telling (without interpretation). Listening to dreams could become a regular part of caring for the elderly and infirm. The effects of regular dream-telling in mentally healthy elderly clinical(More)
Until recently, measurements of temporal summation required the construction of specialized instrumentation or the custom modification of an existing perimeter, which meant that such testing was unstandardized and relatively expensive. This precluded extensive use of this type of visual response testing, especially in a clinical setting. In an effort to(More)
The separation of diffuse loss from more localized loss in the glaucomatous visual field is desirable for a number of reasons. In previous papers, the characteristics of several methods and algorithms for distinguishing among normal visual fields and those exhibiting diffuse and localized loss have been described and compared. In particular, a new diffuse(More)
The separation of local and diffuse visual field loss is important for evaluating the nature and extent of glaucomatous visual field damage. Here, five automated methods for estimating diffuse loss in glaucomatous visual fields (as measured with the Octopus G1 program) are compared. Four are taken from the published literature, and one is introduced in this(More)
The main visual field indices of Flammer and the analogous ones of Heijl have been compared based on a population of 113 glaucomatous visual fields. It is shown that for the population studied, the differences between the two sets of indices are negligible for Octopus G1 program results and that they may thus be used interchangeably.
