“…Apparatus‐assisted visual field testing may use a moving target (kinetic perimetry) or stationary targets (static perimetry). When used in the static form, the automation of threshold determination in the early 1970s resulted in improved efficiency in detecting visual field defects in ocular disease such as glaucoma compared to ‘routine kinetic perimetry’ . Further development using more efficient thresholding algorithms has resulted in continued refinement of visual field testing where it is now effectively one of the gold standards for the diagnosis and progression of many ocular diseases .…”

“…The performances made possible by means of these machines are still on a fairly simple level, usually only one stimulus intensity is used in every tested point. A more ambitious approach has been taken by a group in Bern who have discussed some fundamental points of the theoretical side of visual field determination , Koch et al 1972) and also presented a device for recording, based on a minicomputer (Spahr 1973).…”

An instrument for automatic static perimetry at 14 points across a meridian was constructed and used in a pilot study. The machine was controlled by a computer and the subjects responded to the light stimuli by pressing one of two push-buttons. Most people investigated readily understood the rules at testing. "Blunders" made by the subject were, however, so common, that allowance had to be made in the test programme for a number of mistakes. The test stimuli should be exposed in random order. When the zone of uncertain seeing is wide - this occurs especially in untrained subjects - a simple test logic gives a fairly large variation. An improvement in reproducibility is then obtained by applying a more complicated logic, though at the cost of an increased duration of the test session.

“…Clinical computerized perimetry was developed in the 1970s in Sweden and Switzerland (Heijl & Krakau 1975a,b; Spahr & Fankhauser 1975; Spahr et al. 1978) with the early Competer and Octopus perimeters (Figs 4 and 5).…”

Perimetry, tonometry and epidemiology: the fate of glaucoma management

. This is the lecture that I gave when I was awarded Acta Ophthalmologica’s gold medal and honorary award at the Nordic Ophthalmological Congress in Reykjavik in August 2010. I was inspired by Jared Diamond’s famous book: Guns, Germs, and Steel, The Fates of Human Societies. Diamond is professor of geography and physiology at the University of California, Los Angeles. In this book, which won the Pulitzer Prize, the author explains why the European civilization took over the world. This was all because of predetermined factors of biological nature, environmental differences that were strengthened by feedback loops, and resulted in technological innovation and superiority. In this presentation, I write about the development of glaucoma knowledge and management. I suggest that the development might have been predetermined, just waiting for more facts to be unveiled by research. The technologies tonometry and perimetry have been fundamental as has epidemiological techniques and controlled trials. The new and increased knowledge about glaucoma must now be translated to improvements of clinical glaucoma care. The glaucoma scientists of today and tomorrow will continue to reveal as yet unknown facts, maybe in a predetermined way, but nevertheless of benefit to all patients with glaucoma.
