[Vitreous fluorophotometry after vortex vein occlusion in rabbit eyes]

Vitreous fluorophotometry (VFP) was performed to study the disappearance of fluorescein injected into the vitreous cavity in rabbit eyes after experimental occlusion of the vortex vein. Two vortex veins of the left eye in each rabbit were ligated with 6-0 silk suture and the right eye was saved as control. The rate of disappearance of fluorescein was measured with VFP at 24 hours, 1,2 and 4 weeks after vortex vein occlusion. The rate of fluorescein disappearance at the posterior vitreous was significantly lower in the eyes at 24 hours and 1 week after the ligature than that in the control eyes (p less than 0.01). This result suggests that the active transport systems of the retinal pigment epithelium were disturbed for 1 week after vortex vein occlusion.
