[Study on the growth of orbital volume in individuals at different ages by computed tomography].

Objective: To study the growth aspects of orbital volume and to establish the normal value of orbital volume by computed tomography (CT).

Methods: One hundred and twenty three individuals without eye diseases (64 males, 59 females) were divided into 5 groups according to the age. Orbital volume and length of horizontal transverse axis and anterior-posterior axis of the eye were measured at different levels in original or reconstructive CT images.
