Abstract
- In order to investigate whether the lowering of the intraocular pressure by the compression of the eyebaIl is accompanied by the decrease of water content of the vitreous, rabbit's left eyes were compressed with digital pressure of approximately 2 kg while the right eyes were left undisturbed. The vitreous body and lens were taken immediately after the animals were sacrificed by air injection and their water contents were calculated by weighing. The water contents of the vitreous and lens showed no significant changes in spite of profound faIl of intraocular pressure. It was concluded that the 5 minutes pressure on the eyeball was ineffective to reduce the vitreous volume.
