light adapted eye
2.METHOD:The detec-tion and analysis of dark-adapted red and blue electroretinogram(ERG),light-adapted white ERG and macular cnlor light threshold(CLT)in 58 patients(113 eyes),and color vision(D-15 test)in 29 patients(55 eyes)with RP.
3.The photoreceptor was dark adapted or weakly light adapted by a 0 5 ms conditioning flash (9×10 9 photons/cm 2), 2 5 s prior to the continuous illumination. In 10 mmol/L external calcium the mean size (current time integral)of the bumps was(39 5±1 76)pC; the light adaptation caused a decrease to (10 5±2 29)pC ( n =4).
