PURPOSE: To describe clinical, ultrasound biomicroscopy (UBM), and histopathologic characteristics of benign melanocytic tumors of the ciliary body. DESIGN: Consecutive case series. METHODS: Six patients with a pigmented ciliary body tumour underwent complete ophthalmic examination and UBM, with histopathologic examination carried out on three cases. RESULTS: Six patients presented with a pigmented iridociliary mass, with central displacement of iris root. UBM revealed a stromal mass arising in pars plicata and/or pars plana in all six with a cyst in three cases (intrinsic=1 and extrinsic=2). Iridocyclectomy was performed because of documented growth in three cases, and all three cases proved to be ciliary body spindle-cell naevus. The other three patients have remained stable. CONCLUSIONS: On clinical basis and with available ancillary studies, ciliary body naevi cannot be reliably differentiated from ciliary body melanocytoma and ciliary body melanoma. Even with clinically documented growth, the lesions may prove to be ciliary body naevi.
PURPOSE: To present optical coherence tomography (OCT) for real-time imaging of cyclophotocoagulation effects. METHODS: In a pilot study, real-time transscleral OCT images were generated during diode laser cyclophotocoagulation in four eyes of four patients suffering from uncontrolled glaucoma using a specially designed contact applicator containing the OCT fiber, a focussing fiber optic and the fiber of the diode laser. RESULTS: When the contact system was used, two layers could be differentiated: a superficial thick hyperreflective complex representing conjunctiva, Tenon's capsule, episclera and sclera, and a thinner hyporeflective layer representing the ciliary body. During cyclophotocoagulation, real-time OCT showed a clear and sudden thickening of the ciliary body in the treated area. CONCLUSION: This new OCT device represents a first step towards visual, real-time imaging of cyclophotocoagulation. After further adaptation of the delivery system, further trials are needed to correlate OCT findings with aqueous production and intraocular pressure.
