Enlargement of laser iridotomies over time.

We reviewed the photographs of our patients who have undergone laser iridotomies since 1975. We were able to examine photographs of 21 eyes of 13 patients to determine whether their iridotomies had enlarged over time. We detected an appreciable increase in the size of the iridotomy in seven of the 21. We attempted to determine whether there was any relation between an increase in iridotomy size and several ocular as well as systemic factors, but no such relations could be identified.
