[Measuring cyclodeviations].

This paper presents the results of a physiological study in which four methods used to measure cyclophoria were compared. A total of 50 persons without strabismus participated in a series of experiments. Monocular and binocular measurements were made in primary position. It was found that different methods have different means and ranges. Thus, when conducting clinical follow-up examinations, the same method should be used as before. The double-scale Maddox cylinder was found to be a simple and reliable screening method. The mean is close to 0 degrees and the physiologic range varies from 2 degrees incyclophoria to 2 degrees excyclophoria.

[Cherry red spot without secure evidence of sphingolipidosis (author's transl)].

The occurence of bilateral cherry red spot without neurological disorders is a rare event. The reported case is a girl aged 14 years, whose only complaint was slight deterioration of vision. No secure enzymatic defects was found on examination of leucocytes. Though the cherry red spot is hardly to be explained in another way than by storage in optic ganglion cells. Static perimetry revealed a paracentral depression of contrast sensitivity.

[The importance of the interference fringe visual acuity in the indication of a cataract-extraction (author's transl)].

100 patients have been examined before and after cataract-extraction using the Retinal Visual Acuity Tester, Takata, Japan. Laser produced interference fringes are formed on the retina, as a result the visual acuity can be determined easily before the operation. -- With immature cataracts we obtained a good correlation between the preoperative interference fringe visual acuity and the postoperative visual acuity tested by Landoltrings. Therefore, it can be differentiated whether worse visual acuity is caused by the cataract or by a retinal disease.
