Indirect argon laser drainage of subretinal fluid.

We report on a new method of subretinal fluid drainage which uses the indirect ophthalmoscopic delivery of argon laser energy to perforate the choroid. This carries all the theoretical advantages of drainage with the endolaser probe but is simpler and less expensive. We present a prospective series of 31 patients in whom this method was applied. Satisfactory drainage was obtained in 28. There were 4 cases of limited subretinal haemorrhage attributable to the laser, and 1 case of subfoveal haemorrhage. No cases of retinal perforation or incarceration were observed.
