Fig. 2: Absence of sheen depends on prior 488 nm AF imaging.
From: Loss of sheen in Oguchi disease following short wavelength exposure
A, B Optos pseudocolour images taken from both eyes of a 28-year-old patient with molecularly proven Oguchi disease (biallelic variants in GRK1) following prior AF imaging in the right eye only. The central square of reduced sheen is evident only in the right eye. C, D Optos pseudocolour images taken from both eyes of the same patient following prior AF imaging both eyes. The central square of reduced sheen is evident now in both eyes. In (A, C, D), borders of the square are partly highlighted by yellow arrows.
