ocular hypotony

Introduction

intraocular pressure <= 5 mm Hg

Pathology

• clinically significant changes occur more frequently as the intraocular pressure approaches 0 mm Hg

Complications

• corneal decompensation
• accelerated cataract formation
• maculopathy
• eye pain/discomfort

Management

• correct underlying etiology
• few, if any, useful medications are available that raise intraocular pressure
  • topical ibopamine may raise intraocular pressure but is poorly tolerated
  • ophthalmic glucocorticoids may improve aqueous humor production by decreasing ciliary body inflammation
• increasing fluid intake may slightly increase aqueous humor production

More general terms

• eye disease (ophthalmopathy)
• sign/symptom

Additional terms

• increased intraocular pressure (IOP)
