Bilateral cataracts as the presenting feature of type 1 diabetes in an 11-year-old girl.

Paediatric cataracts can present a diagnostic dilemma to ophthalmologists. Next-generation DNA sequencing (NGS) has been promoted as a tool to expedite the diagnosis of an underlying cause in such cases. The authors present an unusual case of bilateral cataracts in an 11-year-old girl as the first presenting feature of new type 1 diabetes mellitus. Prompt diagnosis and subsequent management of this potentially life-threatening condition were achieved through careful history taking and targeted biochemical testing. The authors feel this case highlights the significance of simple measures such as thorough history taking in the assessment of paediatric cataracts. It is important that these skills are not lost through the availability of clinical tools such as NGS.
