Purpose: To study the refractive changes of form deprivation of myopia. Methods: Haisaik chickens were used to establish the animal models of myopia. Monocular eyelids were sutured for form deprivation on the 5th day after chickens birth. The chickens were examined by optometer and the anteroposterior axis, transverse and vertical diameters were measured by verniermicrometer. Results: Form deprivation leads to myopic refractive abnormality (P<0. 001). The ocular anteroposterior axis (P<0. 005), transverse and vertical diameters lengthen (P<0. 05).Conclusion: Form deprivation is the main cause of the development of myopia. Eye Science 1996; 12:138-139.
