Analysis of Long-term Outcomes of Radiotherapy and Verteporfin Photodynamic Therapy for Circumscribed Choroidal Hemangioma.

Purpose: To determine the long-term therapeutic outcome for different treatments of circumscribed choroidal hemangioma (CCH).

Design: Retrospective observational study.

Subjects: Patients with newly diagnosed CCH.

Staging Uveal Melanoma with Whole-Body Positron-Emission Tomography/Computed Tomography and Abdominal Ultrasound: Low Incidence of Metastatic Disease, High Incidence of Second Primary Cancers.

Purpose: The purpose of this study was to report the results of staging primary uveal melanoma with whole-body (18) fluorodeoxyglucose (FDG) positron-emission tomography/computed tomography (PET/CT) and abdominal ultrasound.

Materials And Methods: From January 2012, patients with uveal melanoma over 4 mm in thickness were staged with FDG PET/CT and abdominal ultrasound.

Results: Over 2 years, 108 patients with medium-to-large melanoma underwent dual imaging.

Rolling resistance and propulsion efficiency of manual and power-assisted wheelchairs.

Rolling resistance is one of the main forces resisting wheelchair propulsion and thus affecting stress exerted on the upper limbs. The present study investigates the differences in rolling resistance, propulsion efficiency and energy expenditure required by the user during power-assisted and manual propulsion. Different tire pressures (50%, 75%, 100%) and two different levels of motor assistance were tested.

Anterior Segment Seeding in Eyes With Retinoblastoma Failing to Respond to Intraophthalmic Artery Chemotherapy.

Importance: Anterior chamber seeding following intraophthalmic artery chemotherapy is rarely reported.

Objectives: To describe clinicopathologic observations in eyes in which intraophthalmic artery chemotherapy for retinoblastoma failed and to report anterior chamber involvement.

Observations: A retrospective case series of 12 enucleated eyes (11 patients) with retinoblastoma refractory to intraophthalmic artery chemotherapy between March 1, 2010, and October 31, 2013, at University College London Institute of Ophthalmology and the Retinoblastoma Service, Royal London Hospital.
