    Notes: Abstract We evaluated the perimetric concept and the technical construction of the Competer. The testprocedures of the Competer are well conceived. The screening-strategy may fail in cases of central islands or large central defects. The interpretation of the visual field results is not easy, due to the use of a numerical print-out which, in addition, is different for screening and threshold examinations. The mechanical and electrical construction of the instrument could be improved. In the accompanying paper (Graniewski et al., 1982) results are presented of a comparative clinical evaluation.

    Notes: Abstract The perimetric concept and the technical construction of the Fieldmaster 101 PR were evaluated. 64 eyes of patients and 10 normal subjects were examined. We conclude that the Fieldmaster is a well-engineered instrument, using an inefficient test strategy. The presentation of visual field results could be impoved. Clinical results of the patient examinations are presented.

    Notes: Abstract The perimetric concept and the technical construction of the Ocuplot were evaluated. The mechanical and electrical construction of the instrument we tested was poor. The manufacturer claims improvements in newer specimens. We examined 87 eyes of patients and normal subjects with the Ocuplot and learned that the test-strategy is not efficient and yields a high proportion of false positive results. Clinical results of the patient-examinations are presented.

    Notes: Abstract The direct compensation method allows for an accurate determination of intraocular light scattering between 3.5 and 25 degrees of scattering angle and is suitable for untrained subjects. The method was used to study light scattering in four forms of hereditary corneal dystrophies. Light scattering is the basis of glare complaints and was compared with visual acuity loss. The findings corresponded to the complaint patterns: in central crystalline dystrophy light scattering can be much increased with relatively well preserved visual acuity. In posterior polymorphous dystrophy the reverse is true. In macular dystrophy (Groenouw II) and lattice dystrophy the situation is more or less intermediate between these two extremes.

    Notes: Abstract We performed a study to evaluate the influence on visual function of intraocular straylight after photorefractive keratectomy (PRK). We present 4 eyes of 4 myopic individuals, who had contacted our clinic for keratorefractive surgical treatment. PRK's were performed with a Summit laser, using a 5 mm ablation zone. The straylight meter was used to measure the amount of intraocular scattered light, the physical cause of glare complaints, before and after PRK. This apparatus uses the direct compensation method to assess the amount of intraocular light scatter. The results showed a significant increase in straylight values, in the tested eyes, during the first two weeks after PRK. After the initial rise, straylight values returned to preoperative levels, except for two eyes that clearly developed a haze higher than grade two. Instead of returning to baseline levels, straylight values remained significantly higher in these eyes.

    Notes: Abstract An overview is given of the basic phenomena that may lead to glare complaints in patients. Prominent among them is increased intraocular straylight; this can be measured. Other causes may include: increased sensitivity to normal straylight, the length of (increased) light and dark adaptation times, (small angle) neuronal lateral interaction. Distinction must be made between disability glare and discomfort glare. Tests have been proposed to determine glare-induced loss of various visual functions. Often the test results are thought to be directly related to straylight but this may be untrue.
