From: Pupillary responses to light are not affected by narrow irido-corneal angles
Representative pupillary constriction responses to blue and red lights in a control subject and in a PACS patient pre- and post-LPI. Representative absolute pupillary constriction responses in a control (a) and PACS patient pre- (b) and post- (c) LPI. Note the reduction in baseline pupil size from 5.8 to 4.7mm in the PACS patient following LPI (c). Such a reduction in baseline pupil size biases the qualitative consideration of the amplitude of pupillary responses to light. When the same profiles are corrected for baseline pupil size (d,e,f), pupillary constriction amplitude no longer appears to be reduced in the PACS patient following LPI (f).
