[Blue-yellow perimetry in rhegmatogenous retinal detachment. Studies before and after therapy in comparison with white-white perimetry].
BACKGROUND
Disturbance of the blue light perceptance in rhegmatogenous retinal detachment was demonstrated by Köllner 1907 with the help of colour-perimetries. We examined the blue- and white-function after retinal reattachment by blue-on-yellow-perimetry compared with white-on-white-perimetry.


METHODS
10 Patients with rhegmatogenous retinal detachment and a visual acuity > or = 0.1 were examined preoperatively, 4 days and 6 weeks after successful buckling procedure. We performed a white-on-white-perimetry as also perimetries with blue stimuli on a yellow luminance background (program 30-2 of the Humphrey Field Analyzer 750).


RESULTS
Four days after surgery the increase in sensitivity was significantly less for the blue-function compared with the white-function. Preoperatively and 6 weeks postoperatively the sensitivities were not significantly different. Between these time-points function recovered in average for both methods from MD -15 dB to MD -5 dB.


CONCLUSIONS
After successful retinal detachment surgery the blue- and white-function increased. Blue-on-yellow-perimetry showed more retinal sensitivity loss than white-on-white-perimetry immediately after surgery. Blue-on-yellow-perimetry measured the same retinal sensitivity loss as white-on-white-perimetry preoperatively and 6 weeks postoperatively.
