Abstract
|
|
|
Purpose: To describe the effects of ciliary body tumor posterior extension on clinical characteristics and surgical outcomes.
Methods: A chart review was performed on patients with ciliary body tumor that visited between January 1, 2005 and December 31, 2015. Patients were divided into three groups based on tumor posterior extension, as follows; group 1, posterior extension within 6 mm of the limbus; group 2, posterior extension of 6-12 mm; and group 3, posterior extension of more than 12 mm from the limbus.
Results: Sixty-one patients were screened, and 49 had pathologically confirmed ciliary body tumors. Malignant melanoma (28 cases, 57.1%) was the most common type of ciliary body tumor. Benign neoplasm was common when the tumor was confined to the ciliary body (group 1), and a higher malignancy rate was observed in those with advanced posterior extension (groups 2, 3) than in group 1 (p = 0.001). Final visual acuity was poorer in patients with advanced posterior extension (p < 0.001), and postoperative retinal detachment rates were higher in these patients (p = 0.007).
Conclusions: Ciliary body tumors with advanced posterior extension had a higher malignancy rate and were associated with poorer visual outcomes.
