[Orbital development after enucleation without orbital implant in early childhood]
1Department of Ophthalmology, Fukushima Medical University, 1 Hikarigaoka, Fukushima 960-1295, Japan.
Purpose:
To evaluate the development of orbital volume in five adults who underwent enucleation without orbital implant during early childhood, using reconstructed computed tomography(CT) images.
Materials And Methods:
The orbital volume of 5 adults who underwent enucleation without orbital implants during early childhood was measured using CT images, and the results were compared between the anophthalmic orbit and the unaffected orbit in each case. The shape of maldevelopmental orbit and the relationship between orbital development and replacement of the prosthesis were also investigated.
Results:
Orbital development in patients who underwent enucleation without orbital implant during early childhood was delayed in comparison with the unaffected orbit, and the delayed development was especially remarkable at the part of orbit corresponding to the equator of the eyeball. Maldevelopment of the orbit was severer in cases without replacement of the prosthesis than with it.
Conclusion:
For the development of orbital volume in anophthalmos after enucleation, orbital volume in place of the eyeball is required. Therefore, orbital implantation at the time of enucleation and replacement of the prosthesis with larger ones as the body grows are important.
