[Multiple evanescent white dot syndrome].

A 38-year-old male patient experienced a unilateral visual acuity decrease to 20/60 and showed white dots at the level of the retinal pigment epithelial interface characteristic of multiple evanescent white dot-syndrome. Fluorescein angiography demonstrated early hyperfluorescent defects and some late staining. In spite of improvement of the visual acuity and the alterations of the fundus, an enlargement of the blind spot and some sharply demarcated depigmentations of the retinal pigment epithelium remain.

[Sudden blindness in an AIDS patient. Simultaneous infection with cytomegalovirus and herpes simplex viruses and development of malignant non-Hodgkin lymphoma].

A 50 year old patient with non-diagnosed HIV-infection at onset of his illness developed impairment of vision and temporary double vision combined with severe hemianopsia. With normal fundus and suspicious Herpes simplex iritis therapy with Acyclovir was started. Primarily the patient showed a good response to the therapy and loss of vision could be prevented.

[Isovolemic hemodilution on non-arteritic anterior optic neuropathy. Initial results of a randomized study].

As there is no generally accepted treatment for non-inflammatory anterior ischemic optic neuropathy, we have started a randomized, controlled clinical trial on isovolemic hemodilution. In this study all patients received a basic treatment of 75 mg of acetylsalicyclic acid daily. Patients were then randomly assigned to either a group without additional therapy or a group with isovolemic hemodilution.
