Bilateral cataracts and insulin oedema in a child with type 1 diabetes mellitus.

We describe a teenage type 1 diabetic girl with painless pedal oedema and bilateral cataracts. She developed oedema after commencement of intensive insulin therapy and achievement of excellent glycaemic control. In addition, she was also found to have bilateral subcapsular cataracts. The oedema subsided spontaneously and she underwent surgical treatment for the cataracts. Insulin oedema is a rare complication of insulin therapy. To our knowledge, co-occurrence of these two complications in a young diabetic patient has not been described before in the English language medical literature.
