Abstract
Abstract: :
Purpose: Identifying and categorizing rare manifestations of ROP in order to reduce diagnostic confusion. Methods: Photographic files of infants were reviewed in order to identify presentations not described in the international classification. They were categorized into groups according to potential causes of the unusual features. Results: The major etiologic categories were persistent fetal vasculature, developmental arrest, fulminate disease and indeterminate. Conclusions: Most findings of ROP were well described by the international classification, however, rare infants present with features that fall outside the international classification. Many of these finding can be understood from the pathophysiology, however, few remain indeterminate. Photographic examples will be presented.
