摘要:
The structure of the pigment epithelium at the ora serrata is examined in 10 human eyes aged from 31 to 90 years. The cells of the pigment epithelium show a different construction depending on their position relative to the ora. Directly at the ora serrata, in the cohesion band, the cells are higher and contain more pigment granula than those which are situated in a central region. In this sector we sometimes find overlapping of cells, which feigns two layers of epithelium. There are clearly fewer basal folding ins of the pigment epithelial cells at the ora than in the other parts of the retina. At the ora serrata pathological changes start in the 3rd decade of life. They include swelling and later on more or less pronounced cystoid degeneration of the epithelial cells. Within Bruch’s membrane two kinds of cells are seen. In the ora gap six types of free cells can be distinguished, whose origin is discussed especially. Probably they originate from the chorioidea, the pigment epithelium and the sensory retina.

摘要:
On the occasion of the observation of 4 cases of melanocytoma of the optic disc, the authors stress the relative rarity of this pigmented tumor, its benignity and its frequent association with a choroidal nevus. The melanocytoma is mostly stationary and produces no functional symptoms. It is generally diagnosed after the age of 30, and its pathogenesis is unknown.

摘要:
Report of an unusual case of Behçet’s disease with bilateral obliterating retinal panarteritis and ischemic optic atrophy. The rarity of the primary optic nerve involvement and chiefly the exceptional full acute bilateral occlusion of the retinal arteries are emphasized. This ophthalmoscopic picture is further clinical evidence for the major importance of the vascular involvement in the pathogenesis of Behçet’s di

摘要:
‘True’ microcephaly is associated with extremely varied ocular abnormalities, the most frequent being squint and optic atrophy. Within the heterogeneous group of the microcephalies it seems we can isolate a syndrome consisting of microcephaly, mental retardation, chorioretinal dysplasia and sometimes microphthalmia and embryological remnants such as persistence of the primary vitreous or persistence of its minor forms. Genetic transmission of such anomalies is generally considered to be autosomal recessive. The cases we are reporting on suggest that in some cases dominant transmission can be incriminated.

摘要:
A method of determining the inorganic constituents of the subretinal fluid using atomic absorption spectrometry is presented. Due to the small volumes available of the samples, the addition of diluents was necessary in order to be able to carry out an analysis of the elements at the most sensitive wavelength in the optimal range of the calibration curve. Details concerning standard solutions, laboratory equipment, sample preparation, precision and accuracy are also considered.

摘要:
The effects of two intraocular irrigating solutions (physiological saline, Mac Carey-Kaufman medium) on the corneal endothelium of the rabbit have been evaluated by scanning electron microscopy. During an experimental anterior vitrectomy on aphakic rabbit eyes, corneas were perfused with a different solution in each eye during a period of up to 75 min and with a maximum of 250 cm3 of liquid. We found a significant difference only after 60 min of perfusion at which time important lesions appeared in the cornea of eyes perfused with physiological saline. The corneas irrigated with Mac Carey-Kaufman medium remained normal.
