Fig. 1 — Representative full-field and pattern ERGs in a normal subject (a), in a case of macular dystrophy (b), cone-rod dystrophy (c), rod-cone dystrophy with relative sparing of macular function (d), complete CSNB (e), incomplete CSNB (f) and birdshot retinochoroidopathy (BRC) before treatment (g) and after treatment illustrating full recovery of the ERG and PERG (h). Recordings showed a high degree of inter-ocular symmetry except in BRC (data from other eye are not shown). Note there is a 20-ms pre-stimulus delay in all single flash ERG recordings. Two responses for each stimulus condition are superimposed to illustrate reproducibility. Broken lines replace blink artefacts occurring after the ERGs, for clarity
