[Contributions to the Aulhorn flicker test. II: The flicker test and the Pulfrich phenomenon in clinical diagnosis].

Fourteen patients with symptoms of acute unilateral optic neuritis were examined with the Pulfrich test and the Aulhorn flicker test. It was found that the positive Pulfrich response and the depth of the apparent orbit depends on the ocular or neural diseases causing a difference in neural conduction from the two eyes. The Pulfrich test is positive for considerably longer than the flicker test.

[The Aulhorn flicker test. I: Concomitant neuritis in malignant non-Hodgkin's lymphoma and leukodystrophy].

Cases of optic nerve involvement in malignant non-Hodgkin lymphoma and multifocal progressive leukodystrophy are reported. In both patients an optic neuropathy was diagnosed secondary to infiltration of the optic nerve and the Aulhorn flicker test was positive. Pathological and neurophysiological conditions which yield a positive flicker test are discussed in the light of these findings.

[Random dot stereograms and the limits of their detectability].

The influence of contrast reduction combined with aniseikonia on disparities in the TNO test was investigated with monocular induced refractive errors by spherical convex and concave lenses. Single contrast reduction was produced by Bangerter foils. Unilateral near vision of 0.

Haemolytic anaemia as initial manifestation of Wilson's disease.

Common manifestations of Wilson's disease are disorders of the liver and brain. A rare complication of this inherited disease is acute intravascular haemolytic anaemia. We report the case of a 33-year old female patient who was admitted to the hospital with acute haemolysis as the initial symptom of Wilson's disease.

[Correction of unilateral aphakia in children, adolescents, and adults at an age when accommodation is still possible].

Twenty-one patients, aged 4-42 years, with unilateral aphakia after perforating injury, were corrected with a combination of spectacles and contact lenses. While taking stereopsis and aniseikonia into consideration, each patient was corrected with the combination of contact lens and spectacles to achieve the best stereoscopic vision. Two of the five children (aged 4 and 7) achieved positive results on stereoscopic acuity.
