B: After light exposure at the age of 22 years, no tapetal-like reflex can be seen. C: After 2 h of dark adaptation at the age of 22 years, a discreet tapetal-like reflex is present. D: After 12 h of dark adaptation at the age of 22 years, a clearly visible tapetal-like reflex is present, most conspicuously temporal of the fovea, in a pattern similar to the initial presentation at the age of 16 years.
