Although not often formally taught nor performed in the Emergency Department, an anterior chamber paracentesis is a fairly quick, simple, and safe procedure with important diagnostic and therapeutic roles.1–20 The long-term prognosis is directly related to the duration of symptoms for disease states that present with increased intraocular pressure, such as acute closure glaucoma and central retinal artery occlusion. In a sense, “Time is Eye.” The Emergency Physician should become familiar with this technique. Its use can potentially prevent irreversible vision loss, especially when medical management is not sufficient in lowering intraocular pressure.
