When evaluating expert systems to be used in clinical perimetry, various aspects of their performance as compared with that of human interpreters must be considered. In this investigation, the results produced by the new Octosmart diagnostic program have been compared with the performance of three interpreters with various amounts of experience in visual(More)
The complexity of visual field result evaluation has increased with the advent of automated perimetry. This in turn makes software assistance such as provided by the new Octosmart program interesting and desirable. Its accuracy and reliability in visual field evaluation must be tested, though, and the testing methodology itself must be developed. For this(More)
The purpose of this study was to assess a 4-month inpatient treatment program based on integrated models for patients with substance use and psychiatric disorders (dual diagnosis patients). On admission and at the 1-year follow-up, a consecutive sample of 118 dual diagnosis patients who entered the program were assessed by interview. Eighty-four patients(More)
The G1 glaucoma program is now widely employed in Octopus automated perimetry in order to detect early visual field damage and as an aid in regular follow up. For some patients, however, the examination duration, about 20 minutes, can be excessive.

The local mean and the average difference of four pairs of test locations within the 26° visual field, situated above and below the horizontal nasal meridian, were used to predict the global field indices MD and CLV of the Gl glaucoma program. Out of 539 examinations (194 eyes suspected of having glaucoma), the local indices NDIFF (describing asymmetrical(More)
