Abstract

Traumatic head injury can cause inappropriately increased Antidiuretic

hormone (ADH) secretion, causing water retention thereby dilutional

hyponatremia. Corticosteroids despite controversies, forms an important

line in management of traumatic optic neuropathy (TON). Treatment

with steroids in patients with undiagnosed Syndrome of Inappropriate

ADH Secretion (SIADH) can cause life threatening hyponatremias.

Patient diagnosed with right eye TON was treated with systemic steroids.

She developed fatigability, vomiting and pedal edema. Electrolyte profile

and urinary sodium showed hyponatremia and natriuresis following

which SIADH diagnosed. Steroids were stopped; Patient was started on

hypertonic saline, salt restricted diet and Tolvapatan after which sodium levels were normalized.
