[Retinal circulation in rhegmatogenous retinal detachment demonstrated by videofluorescence angiography and image analysis. I. The condition of retinal circulation before retinal detachment surgery].
The retinal circulation in cases of retinal detachment was studied in eight eyes with rhegmatogenous retinal detachment. Retinal mean circulation times of the detachment areas and the non-detachment areas were measured by a system using videofluorescence angiography and image analysis with dye dilution technique. The mean circulation times were 4.05 +/- 1.13 seconds (mean +/- standard deviation) in the non-detachment areas and 6.59 +/- 2.91 seconds in the detachment areas. The difference between the two areas was statistically significant (p less than 0.03). The results demonstrated that the velocity of retinal circulation is slower in retinal detachment area.
