[Local resection of ciliary body tumors with vitreoretinal surgery]

To investigate the effects, safety and indication of local resection of ciliary body tumors with vitreoretinal surgery.

Twelve patients with ciliary body tumors, including 5 males and 7 females with the age range 13 - 48 years (average 32 years) were treated with local resection. Ultrasound biomicroscopy (UBM) and ultrasonography confirmed the tumors, and the surgery was performed under hypotensive general anesthesia or local anesthesia. The range of the diameters of tumors was 5 - 20 mm and of the thickness was 4 - 12 mm. Retinal detachment was detected in 2 eyes. Local lamellar sclerocyclectomy or sclerocyclochoroidectomy with vitreoretinal surgery was performed for the resection. The surgery included lensectomy and vitrectomy using perfluorocarbon liquid, endolaser and gases or silicone oil tamponade and also scleral allograft if necessary. The resected tumors were diagnosed by pathologic examinations.

There were no tumor recurrence and metastasis during follow-up 7 - 38 months (average 14.2 months). In the last follow-up date, the visual acuities were less than 0.05 in 1 case, 0.05 - 0.2 in 3 cases and 0.3 - 1.0 in 8 cases. The pathologic diagnoses included malignant melanoma in 5 cases, melanocytoma in 2 cases, adenoma of non-pigmented ciliary epithelium in 3 cases, neurofibroma in 1 case and glioma in 1 case.

Local resection of ciliary tumor not only can conserve the eyeball, but also part of vision, and the accurate diagnosis can also be made from the resected tissues. With vitreoretinal surgery, it can avoid complications and improve the success rate. It is a safe and effective method for benign or malignant tumors of the ciliary body.
