An improved approach to aqueous paracentesis.

We describe a quick and effective technique for performing safe anterior chamber paracenteses. The technique consists simply of inserting a small gauge disposable hypodermic needle without an attached syringe into the anterior chamber. The intraocular pressure and capillary action of the needle readily cause the rapid drainage of aqueous humor. This technique eliminates the cumbersome manipulations and potential complications associated with using an attached syringe for aspiration.
