[Electrooculographic study on the movements of convergence (author's transl)].

Electrooculographic study on the movements of convergence among 53 young subjects clinically normal, in nine different conditions of symmetry, of laterality and of preponderance of the directing eye. The morphology of the graphs are described, the duration of latency, the velocities and the amplitudes were measured for the different types of response, and the statistical disturbances corresponding were compiled. For some of these characteristics were made unpublished acknowledgement.

[Lacrymal gland biopsy and dry-eye syndrome (author's transl)].

The authors describe the "dry-eye syndrom" about 31 cases of lacrymal gland biopsy. There are several tests for diagnosis (Schirmer's and Rose Bengal's tests are more often used). The authors emphazised six types of histologic lesions. Moreover, some data are for them essentials: 1. the contrast between the functionnal signs and the anatomopathology; 2. the association keratoconjunctivitis sicca and rheumatism correspond with an important lesion of the lacrymal gland, in 80% of cases. The aspect is in favour of Gougerot's disease one time of two.

[Uveitis and multiple sclerosis: myth or reality?].

The authors have examined three hundred cases of sclerosis (prospective study of an hundred patients, retrospective study of two hundred observations) in order to assess the frequency of uveitis during the disease and to make out a possible relation between the two diseases. The percentage of uveitis is small: 2% and the frequency of uveitis in multiple sclerosis appears not different of that of a normal population. In spite of the simularity of the pathogenic hypothesis, it does not look that a correlation may be made between the two diseases.

They emphasize: 1. the special frequency with the young person (between 20 and 30 years for allergic conjunctivitis, generally before 7 years for vernal conjunctivitis); 2. the importance of atopic ground; 3. the weak incidence of business; 4. the difficulty of diagnosis, because the monosensibilisations are uncommon; 5. the favourable result of treatment.

[The child's vision and its measurement. Comparative results of different tests of visual acuity in children as a function of age].

The authors describe a new test for determining the visual acuity in pre-school children. It is a picture-test which is composed by pictures of animals of varying sizes, the child being asked to name them in turn. The six pictures (duck, rabbit, cock, elephant, fish, and butterfly) with an homogeneous density, can be utilized according to several manners-appariement or verbal expression--and several distances: 2,50 m or 5 m. That test gave good results on children aged from three years upwards, however the performances could be increased by prectising exercises.
