[Surgical optic nerve decompression in marble bone disease (Albers-Schönberg disease)]. / Zur operativen Optikusdekompression bei Marmorknochenkrankheit (Albers-Schönbergsche Krankheit).

This contribution describes the performance of a transethmoidal decompression of the optic nerve in a 5 1/2-year-old boy with marble bones (osteopetrosis, Albers-Schönberg disease). As a result of the operation the function of the eye still with vision was maintained in an unvarying good state over a follow-up period of some 5 years. In the literature only one other case of this diagnosis has been reported in which such an operation was successfully performed, though in that case with craniotomy. The procedure reported here was the first in which the transethmoidal approach was used, which puts less strain on the patient. In addition to the description of the case the problems involved are discussed.

[Influence of fundus sclerosis and blood pressure on the ability of compensation of ocular circulation (author's transl)]. / Einfluss der Fundussklerose und Blutdruckhöhe auf die Kompensationsfähigkeit des okulären Gefäss-Kreislauf-Systems.

The visual fields of nine eyes (nine patients, aged 51--60 years) with fundus sclerosis and relatively low systemic blood pressure, as well as the visual fields from 25 eyes (25 patients, aged 51--60 years) with increased blood pressure, but no ophthalmologic evidence of arteriosclerosis or fundus sclerosis were investigated with the Goldmann Perimeter before and after the application of pressure to the eye. In the first group pressure application resulted in a narrowing of the I/4-isopters and a marked narrowing of the I/2-isopters of the visual field. The blind spot scotomes become larger and are excluded from the I/2-isopters by their marked narrowing. In contrast, the I/4-isopters on the second group of eyes are little influenced by pressure application and I/2-isopters are never narrowed to an extent which excludes the blind spot from the I/2 scale.

[Results of lens extractions in defective light projection (author's transl)]. / Ergebnisse von Linsenextraktionen bei defekter Lichtprojektion.

It is demonstrated by means of a series of 84 lens extractions in 80 patients that cataract extraction can be meaningful and successful even with defective light projection. Indications discussed are those which are considered urgent (Cataracta hypermatura or primary and secondary glaucoma with concomitant cataract), purely functionally urgent (desire on the part of the patient to have his vision restored) and relative.

[Follow-up of cases of suspected glaucoma (author's transl)]. / Verlaufskontrolle von Glaukomverdachtsfällen

The authors analysed the findings in 280 patients suspected of glaucoma. These patients were controlled over a long period in the course of which 30 developed a glaucoma. The authors recommend the measurement of IOP in all patients in the office so far as there is no contraindication and a 1/2 yearly control of all suspected cases to begin with. They recommend further that after 4 year control the provocative tests should be repeated in case there is yet no manifestation of the disease. Finally they recommend that the pilocarpine-test should be done if the pressure level reaches 26 mm Hg in order to fish out cases of manifest glaucoma early enough.
