[Observations of the course of branch and central venous occlusions (author's transl)]

Electro-ophthalmological responses determined with EOG, photopic and scotopic ERG, flash VEP's and pattern reversal VEP's, in combination with fluorescein angiography and computerized perimetry, were evaluated in seven patients suffering from branch vein occlusions and in eight patients suffering from occlusions of the central retinal vein. The findings were as follows: In cases of branch vein occlusion and central retinal venous occlusion with good prognosis there was a normal or slightly subnormal response in all electro-ophthalmological examinations. In the cases of central retinal venous occlusion with poor prognosis, likely to lead to destruction of the nervous structures of the retina, the response was considerably weaker as regards photopic and scotopic b-waves, and especially VECP's.
