Maximizing local tumor control and survival after proton beam radiotherapy of uveal melanoma.

Purpose: This study reports local tumor control and survival after proton beam radiotherapy (PBRT) of uveal melanoma. It identifies the risk factors for local tumor-control failure and for ocular tumor-related death. It presents the improvements implemented to increase the rate of local tumor control, and compares the survival rate of patients with locally controlled tumors to those of patients who had to receive a second treatment.

Adenocarcinoma of the nonpigmented ciliary body epithelium: report of a rare case.

Acquired tumours of the nonpigmented ciliary body epithelium are rare. We present herein a case of low-grade adenocarcinoma in order to stress the problems related to the clinical diagnosis. The tumour in our case was circumscribed, localised on the ciliary body, and nonpigmented.

Proton beam irradiation of choroidal hemangiomas.

Purpose: To present a large series of choroidal hemangiomas treated with proton beam irradiation and to describe the treatment outcomes.

Methods: We treated 54 eyes of 53 patients with choroidal hemangioma. The lesions consisted of 48 circumscribed hemangiomas and six diffuse hemangiomas in patients with Sturge-Weber syndrome.

[Contribution of ultrasound biomicroscopy to conservative treatment of anterior uveal melanoma].

Background: Ultrasound Biomicroscopy (UBM) is a new ophthalmological imaging technique essentially designed for the study of the anterior eye segment. Over the last 10 months, we've evaluated its contribution to the conservative treatment of anterior uveal melanoma's by means of accelerated proton beam irradiation.

Material: Using UBM, we have examined 55 cases of uveal melanoma's, whose anterior border was situated at 6 mm or less from the limbus and that were consequently treated by proton beam irradiation.
