In general, anisocoria that is greater in the dark indicates disruption of the oculosympathetic pathway (i.e., Horner pupil), resulting in a miotic pupil that dilates slowly (i.e., dilation lag) following removal of light stimulus. If posterior synechiae (abnormal connections between the iris and the lens) develop, the pupil may not be able to dilate fully.
