Acute Bilateral Cataract in Type 1 Diabetes Mellitus

چکیده
We report a case of a 17-year old boy, who presented acute bilateral cataract and complete vision loss within six days, three months after the diagnosis of Type 1 Diabetes Mellitus (T1DM)under optimal metabolic control (HbA1c 6%).At presentation (HbA1c 10.4%) and after correction of diabetic ketoacidosis (pH 6.917)and the beginning of intensified insulin treatment with insulin glargine once daily and insulin aspart before meals,the patient underwent full ophthalmologic examination,which was completely normal.Only few cases with acute bilateral cataract all relatively shortly after the diagnosis of T1DM have been reported. Several hypotheses have been drawn but the exact mechanism of this phenomenon remains unclear. The interesting finding in our case was the clearly elevated insulin autoantibodies (IAA) at the time of cataract formation, negative however at presentation. The relation between the elevation of IAA and cataract formation should be further investigated in diabetic patients.

Purpose Acute development of cataracts that may be transient is known to occur during correction of diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome.
