IN previous papers, a description has been given of the way in which the eye movement potential can be used as a clinical test of retinal function (the *electro-oculogram, EOG). A detailed theoretical and practical account of the proposed clinical test has been given (Arden, Barrada, and Kelsey, 1962) and previous work has been reviewed. In this paper the results of tests upon normal eyes will be analysed, though some of the findings have already been briefly mentioned. The results described below were obtained over a period of 15 months, during which time the routine work was undertaken by more than one person, and the exact procedure of the clinical test was evolved. By analysis of the res'Llts it is therefore possible to discover how modifications of technique (both deliberate variations, and those due to the individual peculiarities of the experimenter) can affect the values obtained in the test. Such an analysis not only enables one to decide whether the findings in diseased eyes depart significantly from the normal, but will also help to guide other workers in the elaboration of similar tests. In addition, the normal subjects have included a series of uniocular aphakics. From the point of view of the EOG, which is a test of retinal function, these eyes may be considered normal, but their investigation has permitted further analysis of the possible contribution of the lens to the standing potential of the human eye. Methods (a) Subjects.-The analysis is concerned with the results obtained on 91 eyes, which have been divided into two groups: 39 preliminary experiments were performed upon our colleagues at the Institute of Ophthalmology, and 52 results were obtained in patients drawn from the special clinics of the Institute. All the subjects had normal visual acuity, full fields, no cardiovascular disease, and in most cases no history of any disease involving the eye, apart from fourteen patients with uniocular aphakia. In these there was no history of myopia, vision was normal after correction, and the fields were full, the lens having been removed after trauma involving the anterior segment only, the operation having been successful and uncomplicated. Six cases were diagnosed as suffering from functional nervous disorders (hysteria, behavioural defects) and two from central lesions.
