Corneal hydrops.

A 23-year-old male presented with sudden, painful decreased vision in his left eye associated with redness, photophobia, and tearing. He gave history of seasonal allergies and vigorous eye rubbing. On evaluation, visual acuity was hand movements close to face. Slit-lamp biomicroscopy revealed severe ectasia in the inferior cornea with overlying edema suggesting presence of corneal hydrops [Fig. 1a]. Anterior segment optical coherence tomography showed multiple stromal fluid pockets [Fig. 1b].[1] Corneal hydrops is characterized by stromal edema due to accumulation of aqueous humor through a tear in descemet's membrane of the cornea in patients with advanced keratoconus and may need surgical management.[2]
