Answer

This procedure involves letting out aqueous from the anterior chamber, which causes a decrease in intraocular pressure. This is believed to allow greater perfusion, pushing emboli further down the vascular tree. However, according to one study, anterior chamber paracentesis added no gain in visual acuity, regardless of the interval between onset of symptoms and time of treatment. [32]
