Effects of retinal detachment surgery on standing potential.
We studied the effects of retinal detachment surgery on the standing potential of the human eye using the electrooculographic technique. Before and two weeks after surgery, we measured the relative base value (rBV) which is the base value of the affected eye divided by the base value of the fellow eye. The rBV distributed around 1.0 before surgery and decreased below 1.0 two weeks after surgery. The change in the rBV through surgery represented by the value R is defined as preoperative rBV minus postoperative rBV divided by preoperative rBV; this was closely correlated with the area of the scleral buckling. The decrease in the rBV was thought to represent the reduction in the standing potential of the operated eye, probably due to circulatory disturbance of the choroid.
