To the Editor.
—I am concerned about a recent letter to the editor published in the Archives.1 This article implied, in its final paragraph, that a marked degree of intraocular pressure (IOP) elevation had not been previously reported following Q-switched neodymium (Nd)-YAG laser iridotomy and that the IOP elevation seen by the authors was causally related to the Nd-YAG laser.In a previously published work, Dr Pollack and I2 documented this IOP rise. In the third paragraph on page 1013, the mean preoperative IOP of eyes treated with Nd-YAG laser was similar to that of eyes treated with argon laser. In the same paragraph, we reported that two patients required the administration of oral glycerin for bilateral IOP elevations greater than 25 mm Hg over baseline IOPs. This is again seen in Figs 4 and 5 on page 1014. Figure 5 demonstrates that two of 20 Nd-YAG laser-treated
