title: Partial lamellar sclerouvectomy of ciliary body tumors in a Korean population.
abstract: OBJECTIVE
  To describe the clinical characteristics of ciliary body tumors, surgical outcomes, and factors associated with poor visual outcome and metastasis.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  Medical records of 27 patients with ciliary body tumors who underwent partial lamellar sclerouvectomy in a single-center setting (Seoul, South Korea) were reviewed. Surgical outcomes were reviewed, and clinical characteristics were analyzed with respect to visual prognosis and globe retention rate.
  
  
  RESULTS
  Tumors were diagnosed histopathologically as benign in 8 (30%) cases and as melanoma in 19 (70%) cases. Patients had a median age of 48 years. The median follow-up was 3.5 years (range, 0.5 to 6 years). The tumors had a median diameter of 11 mm and a median thickness of 9 mm. The globe was retained in 20 (74%) eyes, with visual acuity of 20/400 or better in 13 (48%) eyes and 20/40 or better in 6 (22%) eyes. Choroidal involvement of tumor (P = .003), larger diameter of tumor (P < .001), and thicker tumor (P < .001) were associated with poor visual outcome. Local recurrence (P = .003) and presence of epithelioid cells (P = .040) were predictive factors for metastasis in melanoma patients. Kaplan-Meier estimates of metastasis-free survival at 3 and 5 years for melanoma patients were 82% and 55%, respectively.
  
  
  CONCLUSIONS
  Partial lamellar sclerouvectomy is a reasonable primary therapeutic option in ciliary body tumors, and good visual prognosis is expected in selected cases.
