The pupils were dilated at presentation, 7.5 mm (OU) in dimension [Figure 1a], and showed a vermiform segmental contraction, in the superior quadrants, reducing to only 7 mm, to bright light. Pilocarpine (0.1%) was instilled in both eyes every 5 min for 45 min, following which pupillary constriction to 3 mm (OU), was noted [Figure 1b].
