Reversible pupillary miosis during a hyperglycaemic episode: case report.

A young female patient presented with non-ketotic hyperglycaemia, pupillary miosis and clouding of consciousness. The initial blood glucose was 83.3 mmol/l; there was no metabolic acidosis. After insulin therapy and improved diabetic control, pupillary function returned to normal. There was no other associated somatic or autonomic nerve dysfunction.
