[Visual perception under the influence of a tranquilizer (author's transl)].

In a double blind study, the influence of the tranquilizer Camazepam on different ophthalmological parameters was examined. The 12 test persons were between 20 and 30 years of age and had entirely normal ocular findings. Visual acuity was uninfluenced by a single dose of 40 mg of Camazepam, reflecting the very slightly hypnotic effect of the drug. Roughly half of the patients showed a considerable widening of the visual field, thought to be related to the stimulation of attention caused by Camazepam. Finally the lack of muscle relaxing properties of Camazepam was confirmed as regards the extraocular muscles, since their balance remained uninfluenced as well.

[Ultrasonography of orbital rhabdomyosarcoma in children (author's transl)].

We report on 4 children suffering from orbital rhabdomyosarcoma. The ultrasonographical findings in both A and B mode are: irregular structure, poorly outlined borders, very low reflectivity, weak sound attenuation, hard consistency and little mobility of the tumor. There was no correlation between the ultrasonographical findings and the histological type of rhabdomyosarcoma.

[Ocular side effects through oral contraceptives (author's transl)].

Functional and morphological side effects of oral contraceptives on the eye are demonstrated by own findings and by literature. Possible aetiopathogenetic interrelations and the significance of an intensive ophthalmological examination of all patients who complain about decreasing vision under hormonal contraception are pointed out.

[B-scan echography in eye and orbital diseases].

After a short description of ultrasound A- and B-scan-techniques, the ultrasonic findings in the different diseases of the eye and orbit are discussed. The results, as presented in this paper, show that ultrasound proves to be a useful aid in the evaluation and differential diagnosis of ocular pathology.

[Acute keratoconus in mongolism (author s transl)].

Ten cases of mongolism are reported in which acute keratoconus developed. The results according to age and sex distribution, onset of the disease, status of the fellow eye, and histology of the cornea are compared with former reports. Our theory of the etiopathogenesis of acute keratoconus in patients with trisomy 21 and other diseases with generalized weakness of the connective tissue is presented and discussed.

[B scan sonography in drusen of the optic disc].

The B scan sonographic characteristics of drusen of the optic disc are strong reflexion at low energy levels, shadowing in oblique and pseudobroadening of the optic nerve in orthograde beam direction. These signs provide additional security in differentiating deep drusen from a choked disc.

[Ophthalmologic symptoms in trisomy 22 (author's transl)].

After a brief description of the ophthalmological findings in the autosomal trisomies, a case of the extremely rare trisomy 22 is reported. Ophthalmological abnormalities seen were hypertelorism, epicanthus, antimongoloid slant, microphthalmus, microcornea, persistent pupillary membrane, lens opacities and chorioretinal colobomata.

[Ophthalmologic symptoms of Down's syndrome (author's transl)].

After a short description of the general symptoms of Down's syndrome, the ophthalmologic aspects of the disease are discussed. The study is based on the examination of 1047 mongolian children. The various eye-symptoms were present in different frequencies according to sex and type. The results were compared with those in the literature of the last 100 years and identical as well as highly significant divergent values were found.

[An equidensometric method for objective evaluation of ultrasonic b-scan pictures (author's transl)].

An equidensometric procedure is presented for achieving objective evaluation of ultrasonic B-scan pictures. Using special film (Agfacontour film) it is possible to select and show individually areas of equal brightness appearing on the B-scan, so called "equidensites". This can be done by colouring each area differently or by using a system of symbols. There is a description of the way in which the Agfacontour film works and is processed. Clinical evidence can be provided to prove the equidensometric evaluation of ultrasonic B-pictures of the eye can offer a considerable amount of additional information.

Delayed suprachoroidal hemorrhage after penetrating keratoplasty.

We report on an aphakic 30 year-old patient who underwent penetrating keratoplasty on his only functioning eye. On the first day after the operation he developed a total choroidal detachment due to suprachoroidal bleeding. The patient had no sense of orientation. Vision decreased to faulty light perception. One week postoperatively a posterior sclerotomy was performed in order to drain the suprachoroidal blood. Via a paracentesis the globe was pressurized with hyaluronic acid. The following day the suprachoroidal blood had almost disappeared. The retina had become reattached. During a follow-up period of 2 years the visual acuity remained 20/30.
