Abstract

Mittendorf’s dot and posterior embryotoxon are both congenital abnormalities affecting the anterior segment, which arise during early foetal life. We report of a 36-year-old female patient newly diagnosed as having a potentially occludable anterior chamber angle in the right eye and coexisting Mittendorf’s dot and posterior embryotoxon. The patient elected to undergo prophylactic laser iridotomy in the affected eye. These findings may serve as additional factors to consider in the management of patients with narrow anterior chamber angles.
