Abstract


Vitreous hemorrhages of white rabbit eyes were obtained by the following three methods and their ultrasonographies were checked several times for four weeks. 1st 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,
3rd 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.
