Why the study?
Do pupillary light reflex latency and darkness adapted pupil size differ between control subjects and diabetic patients with and without cardiovascular autonomic neuropathy?

Parasympathetic pupillary dysfunction appears to precede sympathetic pupillary denervation in diabetic autonomic neuropathy.
No takes yet. Share an insight, caveat, or question.
May indicate early parasympathetic pupillary dysfunction in diabetic neuropathy; hypothesis-generating, needs prospective validation before clinical adoption.
Lanting et al. (1990) studied this question.
