Anterior chamber paracentesis
Surgical procedure to reduce intraocular pressure of the eye
Anterior chamber paracentesis (ACP ) is a surgical procedure done to reduce intraocular pressure (IOP) of the eye. The procedure is used in management of glaucoma and uveitis . It is also used for clinical diagnosis of infectious uveitis.
Uses
Anterior chamber paracentesis is used in the management of acute angle closure glaucoma , and uveitis.[ 1] [ 2] It can also prevent a raise in IOP after intravitreal injections .[ 3] Aqueous humor collected using anterior chamber paracentesis may be used for clinical diagnosis of infectious uveitis.[ 4]
Procedure
In this procedure aqueous humor from the anterior chamber of eyeball is drained out by using a tuberculin syringe, with or without a plunger attached to a hypodermic needle or a paracentesis incision.[ 1] Eye is anesthetized using proparacaine or tetracaine eye drops prior to ACP.[ 5] Paracentesis is performed through the clear cornea adjacent to the limbus .[ 5]
Complications
Pain, traumatic injuries of the iris , corneal abscess, inadvertent lens touch, occurrence of Anterior chamber fibrin , Intraocular hemorrhage , decompression retinopathy , hyphaema , ocular hypotension due to leakage and exogenous endophthalmitis are complication of ACP.[ 1] [ 3] [ 6] Traumatic cataract may occur secondary to lens trauma.[ 5]
