Abstract

PURPOSE: We present case report of a patient with raised intraocular pressure (IOP) post drinking large bolus of water orally over a short span of time and assess the usefulness of the water drinking test in patients with no high-risk factors for glaucoma
Observations: A 54-year-old male patient with a history of bilateral varicocele with mild hydroureteronephrosis presented with complains of sudden onset painful blurring of vision in both eyes with headache and nausea. Symptoms began shortly after patient had 3litres of water over a span of 1 hour to undergo uroflowmetry as advised by the treating surgeon. On examination he had bilateral elevated IOP. The water drinking test showed a peak intraocular pressure of 55mmHg in right eye and 52 mmHg in left eye on NCT that responded well to oral and topical IOP lowering drugs. Gonioscopy demonstrated open angles and fundus examination showed non glaucomatous optic nerves with no RNFL loss or splinter hemorrhages.
