Abstract
Purpose: To describe the ideal size of a laser iridotomy and discuss its importance.
Design: Perspective.
Methods: Articles in ophthalmology literature on this topic were reviewed, and commentary is provided based on the authors' experiences.
Results: An ideal laser iridotomy size is 200 microns and larger, especially in eyes with uveitis. The final size of an iridotomy must be confirmed after the effects of the pilocarpine has worn off and the pupil is not being constricted by light. A location of the iridotomy furthest from the lid margin may reduce the chances of dysphotopsias and thus allow for an adequately sized iridotomy.
Conclusion: An iridotomy of an ideal size is needed to reduce the pressure differential on both sides of the iris so as to be effective in eliminating pupillary block.

Published monthly since 1884, the full text of the American Journal of Ophthalmology and supplementary material are also presented online at www.AJO.com and on ScienceDirect.
The American Journal of Ophthalmology publishes Full-Length Articles, Perspectives, Editorials, Correspondences, Books Reports and Announcements. Brief Reports and Case Reports are no longer published. We recommend submitting Brief Reports and Case Reports to our companion publication, the American Journal of Ophthalmology Case Reports.
Manuscripts are accepted with the understanding that they have not been and will not be published elsewhere substantially in any format, and that there are no ethical problems with the content or data collection.
