Abstract

Vitreous hemorrhages of white rabbit eyes were obtained by the following three methods and their ultrasonographies were checked several times for four weeks. 1 st group: fresh human blood was injected into the vitreous cavity through the sclera, 2 nd group: oxalated human blood was injected into the vitreous cavity in the same way, 3 rd group: a 26 gauge needle was inserted into the vitreous cavity and retinal vessels were mechanically ruptured to cause vitreous hemorrhage. Ultrasonography of the above groups revealed no definite differences between groups, but a high echo from the vitreous hemorrhages in initial stage changed to several low echoes in later stage. This fact was well matched with funduscopic observation for gradual absorption of the vitreous hemorrhage.
