[Lamellar keratoplasty, ipsilateral rotation-autokeratoplasty and contralateral autokeratoplasty (author's transl)].

During the years 1967--1977, there were performed about 500 mostly perforating keratoplasties. Among these there were special groups: 50 lamellar keratoplasties (43 central, 7 marginal), 5 perforating ipsilateral rotation-autokeratoplasties 2 perforating contralateral autokeratoplasties. The results encourage to use these special keratoplasties more often instead of the usual perforating keratoplasty.

[Electro-ophthalmological observations on the course of unilateral tapetoretinal degenerations (author's transl)].

A 32-year-old female patient suffering from a unilateral tapetoretinal degeneration for at least 7 years was investigated. The affected eye exhibits a typical fundus, concentric reduction of visual field, and a monophasic course of dark adaptation. The electroretinogram of the affected eye is extinguished; the electrooculogram does not show a light peak. The visual evoked cortical potential of both eyes shows a normal amplitude-stimulus intensity function. However, the first negative deflection exhibits a small difference of implicit time between the normal and affected eye. The normal eye does not show any pathological alteration.
