Nonarteritic anterior ischaemic optic neuropathy in Addison's disease.

Purpose To report three cases of Nonarteritic anterior ischaemic optic neuropathy (NAAION) in patients with Addison's disease Methods We present a retrospective review of patients presenting with NAAION with underlying Addison's disease. Results Three eyes of two young patients presented with NAAION. Both patients had underlying Add*ison's disease with episodes of prolonged hypotension. Conclusion To our knowledge, this is the first published report of NAAION associated with Addison's disease. As hypotension may be one of the few situations, in which NAAION may be treatable and the visual loss reversible, it is important to recognize and treat sustained episodes of hypotension in these individuals.
