Abstract:
A 53-year-old contact lens wearer on renal dialysis developed visual impairment due to corneal opacity. The opacity was of a crystalline type and diffusely scattered in the anterior cornea. As oxalosis was suspected ascorbic acid was immediately omitted from the dialysis treatment schedule. Within a few weeks the visual acuity recovered and the corneas became nearly clear. The cornea is an uncommon manifestation site for oxalosis. Nevertheless, one should be aware of this possible sign for oxalosis, which can be a life-threatening complication of treatment with high dose ascorbic acid.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
