Nanophthalmic Eyes and Neodymium-YAG Laser Iridectomies

Arch Ophthalmol. 1987;105(4):455-456. doi:10.1001/archopht.1987.01060040025008

To the Editor.  —We congratulate Karjalainen et al1 on their interesting report of bilateral nonrhegmatogenous retinal detachments following neodymium-YAG laser iridotomies in nanophthalmic eyes. From our experience with nanophthalmic eyes and laser iridectomies, we thought that the following thoughts might be of interest:

  1. The authors mentioned that in their performance of YAG laser iridectomies, they used a total of 22 mJ in the left eye and 220 mJ in the right eye. The amount of energy used in the right eye was very high, and even in the normal eye this amount of energy can predispose to retinal complications. In addition, it is a known fact that the presence of preexisting low annular choroidal detachments and retinal detachment can aggravate the angle closure glaucoma seen in nanophthalmic eyes.

  2. They also described angle closure and flat anterior chambers in both eyes.
