intense photophobia and ERG CHU not really normal but not pathological nor frankly, that left little doubt about the good sensitivity of the cones can not be fixed. Then at least to be sure, the ophthalmologist had prescribed a comprehensive review to the clinic Sourdille: ERG, PEV, EOG sensory and visual field . I just received a copy of the minutes with the same curves plotted
:-) We start by visual field, which does not show a deficit above the left eye, normal view of ptosis and foveolar sensitivity not top, which nystagmus is the culprit. So we can say normal visual field.
It's the same with ERG dark adaptation and adjustment to the brightness, as well as sensory EOG , they show that my retina is fine, especially since this is my cones about them that had questions. The
VEP , on the right are slightly reduced in amplitude and latency limit, left normal latency but reduced amplitude frankly, with no detectable EPI for small checkerboard of 15 '. Blame the nystagmus.
So getting back to photophobia, the explanation is trivial: we know that awakens photophobia diplopia, nystagmus, and more. Two good reasons not to bear the light.
