[Electroophthalmological, Fluorescence angiographical and computer perimetrical examinations in cases of contusio bulbi (author's transl)].

In seven patients with diminished visual acuity, caused by oedema of the retina after contusio bulbi, the EOG, the photopic and the scotopic ERG as well as the VECP, elicited by luminance (H-EP) on the one hand and by pattern reversal-stimulation (M-EP) on the other hand, were registered. These registrations were made both during and after the acute phase. The results were then compared with the results of the normal fellow eyes. Additional fluorescence-angiographic and computer-perimetric examinations were performed. All EOG and ERG components studied showed a significant reduction in the acute phase and a significant increase -- with the exception of the photopic b-wave -- in the regression of the oedema of the retina. However, the values of the affected eyes never reached the values of the normal fellow eyes. The different behaviour of the H-EPs and the M-EPs is striking. While the medium values of the H-EPs showed little reduction in all examinations, the M-EPs showed a highly significant decrease or increase, with the visual acuity and the M-EP showing corresponding behaviour.
