[Multi-handicapped blind children].

In Magdeburg on the key day of the 31st of December 1983 73 children at 1 to 16 years of age have been registered to be blind or suspected to be blind. Nearly half of them (n = 38) is multiply injured, that means, besides blindness they show another relevant organic affection. A central position in the causes of blindness in multiply impaired children hold the retrolental fibroplasia, the intensive myopia, and the amblyopia (mostly temporary diagnosis).

[An objective rapid testing method for viability of corneal endothelium after conservations (author's transl)].

An objective procedure for assessing damage to corneal endothelium is described; it is based on photometrical determination of the dye toluidine blue absorbed by damaged cells. This inexpensive quick test is suitable both for preoperative assessment of grafts and for checking procedures for cornea conversation. The use of the peripheral region of the endothelium enables the remaining central trephined portion in transplantations.
