title: Creation of the transformed Q statistic probability distribution to aid in the detection of abnormal computerized visual fields.
abstract: This paper describes the creation of a new Q statistic which can be calculated from the threshold data of a single computerized visual field. The Q statistic can then be used to decide, at a given significance level, whether the individual field is normal or abnormal. The Q statistic is constructed to be particularly sensitive to the situation in which only a small subset of the values in the field is depressed, making it particularly useful in the diagnosis of early glaucoma.
