Abstract:  Objective To evaluate the development of the orbit in patients without eyeball and without orbital implant during minors. Design Retrospective case series. Participants Forty-one cases who had underwent enucleation during minor without orbital implants. Methods the areas of the anophthalmic orbital entrance were measured by CT. Comparisons were made between the anophthalmic and normal sides. Main Outcome Measures Area of the anophthalmic orbital entrance. Results There were significant differences of the area of the anophthalmic orbital entrance (10.67±1.41cm2) between the eyeball-enudeated orbit and the fellow orbit (12.03±1.41cm2) (P=0.000). There were significant differences of the area of the anophthalmic orbital entrance between the eyeball-enudeated orbit and the fellow orbit in the age group of 0~6 years-old and the age group of 7~12 years-old (P=0.000, 0.018) , but no difference in the age group of 13~18 years-old (P=0.09). The difference between the area of the anophthalmic orbital entrance and the area of the fellow orbital entrance is significant difference between weared and without weared the prosthesis group(P=0.004). Conclusion Enucleation during minor can cause orbital growth retardation in the anophthalmic orbit, and the younger the patients had undergone enucleation the more orbital growth retardation. The replacement of the prosthesis with growth is important. (Ophthalmol CHN, 2015, 24: 59-61)
