[Treatment of venous thrombosis of the retina with prostacyclin].

Prostacyclin (PGI2) was used in the treatment of 10 patients with retinal venous thrombosis. All changes in 6 eyes with the non-ischaemic type of venous obstruction resolved completely, with marked visual improvement. The course of 3 ischaemic venous thromboses was unaffected by the treatment. In one eye ischaemic retinal areas were first noted months after therapy. All ischaemic fundi were subjected to adequate laser coagulation. In spite of the small number of patients it can be concluded that PGI2 does not seem to alter the course of the ischaemic type of retinal venous thrombosis.
