—With great interest I read the report by Kaufman et al1 on intraocular pressure (IOP) after panretinal photocoagulation that was published in the Archives in June 1987. To elucidate the reasons for the quantitative differences between our observed decreases in IOP, I should like to ask the authors the following questions: Is it possible to distinguish between effects on IOP from panretinal photocoagulations made with the xenon arc and with the argon laser? Is it possible to distinguish between effects on IOP from treatments performed with the patient under retrobulbar anesthesia (RBA) and those performed without RBA?My reasons for asking are as follows: As I have reported,2 pressure decreases (2.2 mm Hg) were only significant after six months if the photocoagulations were made with the xenon arc and RBA and no effect on IOP was recorded when comparable treatments were made with the argon
