“…To understand the possible relationship between retinal function and morphological events, we in figure 6 we have compiled temporal data concerning changes in ERG and GFAP/PKC alfa expression. ERG supernormality has not previously been described after laser phoRetinal function after focal laser photocoagulation Page 15 tocoagulation, but the abnormal response has been found in a relatively unusual form of cone dystrophy, and also early in uveitis [18,25,36]. In the experimental situation, a disturbed phototransduction in the form of elevated levels of cyclic GMP by direct injection into outer segments or inhibition of phosphodiesterase (PDE) has been reported to amplify rod b-wave amplitudes substantially [26,31].…”
