Management Issues in Conjunctival Tumours: Conjunctival Melanoma and Primary Acquired Melanosis.

Conjunctival melanoma is a rare malignant condition of the ocular surface. It is potentially lethal, with regional lymph node spread often preceding distant solid-organ metastasis. Due to its rarity and the long latency between treatment and local recurrence or the development of metastases, it is difficult to study.

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.

Visual Loss from Choroidal Melanoma Mimicking Neurological Syndromes.

Melanoma of the eye is rare, but can mimic a range of disorders. This report highlights 2 cases of choroidal melanoma with vision loss mimicking neurological diagnoses. The first patient is a 41-year-old white male with a known history of multiple sclerosis and a previous episode of optic neuritis in the right eye, who presented with a 6-month history of decreased vision in the same eye, and occasional photopsiae.

Combined PKC and MEK inhibition for treating metastatic uveal melanoma.

Uveal melanoma (UM) is the most common primary intraocular malignancy and the second most common form of melanoma. UM has a strong tendency for metastatic disease, and no effective treatments have yet been identified. Activating oncogenic mutations are commonly found in GNAQ and GNA11 in UM, and inhibiting key downstream effectors of the GNAQ/11 signaling pathway represents a rational therapeutic approach for treating metastatic UM.

Radiotherapy in thyroid eye disease: the effect on the field of binocular single vision.

Purpose: Thyroid eye disease (TED) can be a functionally disabling condition if ocular muscle involvement causes diplopia. The extraocular muscle restriction creates a reduced or eccentric field of binocular single vision (BSV). Orbital radiotherapy is now widely used in the treatment of TED, and although it has been reported as improving ocular motility, there have been few quantitative studies of the effect of treatment on ocular motor function.
