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.
