Pfeiffer syndrome: systemic and ocular implications.

Abstract

BACKGROUND: In 1964, Pfeiffer described a three-generation family in which eight individuals had a syndrome consisting of craniosynostosis, broad thumbs and great toes, and partial syndactyly of the hands and feet. Pfeiffer syndrome affects males and females equally, and is most commonly a result of de novo mutations, but can be inherited in an autosomal dominant fashion. Pfeiffer syndrome is considered Type V of the five acrocephalosyndactly syndromes (ACS), a group of rare genetic diseases that involve premature closure of the cranial sutures. Cohen, in 1993, further described Pfeiffer syndrome and it's various expression patterns by creating three subgroups of the syndrome. CONCLUSIONS: While Pfeiffer syndrome is clearly a rare disorder, affecting 15 of every 1 million births, there has been a series of publications reviewing the difficult differential diagnosis among Pfeiffer types and between the other acrocephalosyndactly syndromes. While these publications individually focus on a variety of specific systemic and ocular implications of the syndrome, together they encompass the scope of the syndrome. Since Pfeiffer syndrome mainly affects the craniofacial regions, the eye care professional plays an essential role in diagnosis and management. What follows are guidelines to aid in the diagnosis, ophthalmic and functional testing, and management of this disorder.
