To the Editor.  —I read with interest the article by Sorokanich and colleagues1 concerning acute angle closure glaucoma and acute hyperglycemia. The authors postulate that enough lens swelling was induced by the hyperglycemia (180 mg/dL [10.0 mmol/L] one day before the episode) to cause shallowing of the anterior chamber and to precipitate acute angle closure glaucoma.I have been carefully documenting changes in light scattering in a group of diabetic patients with the use of a system (Topcon SL45 photographic system, Topcon Inc, Tokyo) based on the Scheimpflug principle for 4½ years. (Legal requirements governing consent have been met.) The patient population consists of approximately 150 patients with diabetes, most of whom are taking insulin. Over the course of three years of observation, I have found, by densitometric analysis of light scattering, that the superficial anterior cortex and the clear zone of dysj unction are changing at the rate
