• We used the argon laser to perforate the choroid and drain subretinal fluid during retinal detachment surgery in 24 consecutive patients. The procedure was successful in 23 of 24 patients (95.8%). The laser settings required for perforation ranged from 0.02 to 0.2 s and from 200 mW to 2.0 W. Because it is not necessary to enter the subretinal space with a solid, pointed object, laser choroidotomy may reduce the incidence of retinal perforation. In addition, the laser has the advantage of cauterizing small vessels during choroidal puncture, which may reduce bleeding at the time of drainage.
