An aqueous paracentesis pipet.
We describe a glass pipet tipped with a short, sharp, 30-gauge needle for performing aqueous paracentesis. The design eliminates the possibility of needle bending and minimizes fractional resistance during limbus penetration; it also allows quicker recovery of aqueous samples. A small plastic bulb at the upper end facilitates removal of aqueous samples from the pipet.
