The orbital cysts were classified as exophytic and endophytic, according to their site of attachment in relation to the orbital rims. This classification can explain the different natural history of these lesions. The exophytic cysts growing externally are discovered in childhood, whereas the endophytic ones are discovered later in life when they produce bone damage, with or without invasion of the adjacent structures. ©1995The American Society of Opthalmic Plastic and Reconstructive Surgery, Inc.
