Iridoplasty (the molding of the iris) is a procedure that can be performed using low energy argon laser to place circumferential burns to the iris to cause contracture of the iris away from the anterior chamber angle.

Argon laser light is delivered through an Abraham iridotomy lens using a 500-μm spot size for a duration of 0.5 to 0.7 seconds. Treatment is initiated at 240 mW of power and increased until the surgeon sees the tissue contract.

Argon laser peripheral iridoplasty (ALPI) is a procedure in which long-duration, low-power contraction burns placed circumferentially on the peripheral iris open an appositionally closed anterior chamber drainage angle (Figure 24-1).

Argon laser peripheral iridoplasty (ALPI) is a simple and effective means of opening an appositionally closed angle in situations in which laser iridotomy either cannot be performed or does not eliminate appositional angle closure because mechanisms other than pupillary block are …

Studies have reported that argon laser peripheral iridoplasty (ALPI) is a simple and safe procedure that effectively opens closed angle . This method is useful in reversing APAC attack when antiglaucoma medications fail and corneal edema and shallow anterior chamber preclude immediate laser iridotomy [ 9 ].

Argon laser peripheral iridoplasty (ALPI) is a simple and effective means of opening an appositionally closed angle in situations in which laser iridotomy either cannot be performed or does not eliminate appositional closure because mechanisms other …

Argon laser peripheral iridoplasty is a useful procedure to eliminate appositional angle closure resulting from mechanisms other than pupillary block. For those eyes with angle closure originating at an anatomic level posterior to the iris, such as plateau iris, lens-induced angle closure, or poster …

The aim of argon laser peripheral iridoplasty is to open up the drainage angle of the eye so that aqueous humour can flow through as normal. This should prevent or treat angle closure glaucoma and help to lower intraocular pressure. This is achieved by applying a laser beam to the iris, pulling it out of the angle and thinning it a little.

2024年1月2日 · Argon laser peripheral iridoplasty (ALPI) is a simple and effective means of opening an appositionally closed angle by placing contraction burns of longer duration, lower power, and larger spot size in the iris periphery to contract the stroma at the site of the burn, compacting the iris stroma and physically pulling open the angle (Figure 1 ...

Argon laser iridoplasty is a safe and effective procedure for patients with narrow angles and/or plateau iris syndrome whose angles remain narrow after laser iridotomy. When properly performed, the procedure consistently delivers a long-term benefit to …
