PurposeSuspicious neoplastic conjunctival lesions often require wide excision with tumour-free margins, leaving significant conjunctival defects requiring reconstruction. In this study we report the results of using fresh frozen amniotic membrane grafts (AMG) after wide excision of potentially malignant lesions.MethodsRetrospective review of 53 patients; between January 2011 and April 2014. Conjunctival lesions were excised with a non-touch technique (2 mm margin) and sent for histopathological analysis. The surgical margins were treated with cryotherapy and a fresh frozen AMG was used to cover the defect...

OBJECTIVE: The objective of this study was to determine the use of 3D printed model of an eye with intraocular tumor for linear accelerator-based stereotactic radiosurgery. METHODS: The software for segmentation (3D Slicer) created virtual 3D model of eye globe with tumorous mass based on tissue density from computed tomography and magnetic resonance imaging data. A virtual model was then processed in the slicing software (Simplify3D(®)) and printed on 3D printer using fused deposition modeling technology...

BACKGROUND AND PURPOSE: To analyze treatment plan robustness and plan optimization strategies of (106)Ru eye plaque brachytherapy using a novel software tool. MATERIALS AND METHODS: A treatment planning software was developed that allows to calculate dose-volume metrics. Plaque misplacements were simulated and evaluated with respect to the effect on tumor coverage and dose changes in critical structures. Two treatment plan optimization approaches were analyzed: (a) reducing plaque size and (b) shifting the plaque away from organs-at-risk (OAR)...

PURPOSE: Our preferred treatment for juxtapapillary choroidal melanoma is stereotactic radiotherapy. We aim to describe our immobilization system and quantify its reproducibility. MATERIALS AND METHODS: Patients were identified in our radiosurgery database. Patients were imaged at computed tomography simulator with an in-house system which allows visual monitoring of the eye as the patient fixates a small target. All patients were reimaged at least once prior to and/or during radiotherapy...

IMPORTANCE: A small percentage of patients with uveal melanoma will experience local recurrence following brachytherapy. An understanding of the recurrence patterns can improve early recognition and management of local treatment failure. OBJECTIVE: To evaluate the patterns, the risk factors and the management of recurrence following brachytherapy in patients with posterior uveal melanoma. DESIGN: Retrospective cohort study.

PURPOSE: Cysts of the iris pigment epithelium (IPE) can involve the pupillary margin, midzone, or peripheral location or can be free-floating in the aqueous or vitreous or lodged in the anterior chamber angle. Avariant of IPE cyst, known as iris flocculi, can be a marker for systemic thoracic aneurysm. DESIGN: Review of IPE cysts and description of new observations of the lesions. METHODS: Review of IPE cysts. RESULTS: Lesions in 672 eyes were classified as of the pupillary margin (n = 49; 7%), midzone (n = 188; 28%), peripheral (n = 424; 63%), or dislodged/free-floating (n = 11; 2%)...

PURPOSE: Plaque brachytherapy (BT) and Gamma Knife radiosurgery (GKRS) are highly conformal treatment options for choroidal melanoma. This study objectively compares physical dose and biologically effective dose (BED) distributions for these two modalities. METHODS AND MATERIALS: Tumor and organ-at-risk (OAR) dose distributions from a CT-defined reference right eye were compared between (103)Pd COMS (Collaborative Ocular Melanoma Study Group) plaques delivering 70 Gy (plaque heterogeneity corrected) over 120 h to the tumor apex and GKRS plans delivering 22 Gy to the 40% isodose line for a representative sample of clinically relevant choroidal melanoma locations and sizes...

BACKGROUND/AIMS: To present a new method to determine dose depth and the distance from the concave side of the plaque to the tumour base in patients with uveal melanoma treated with ruthenium-106 based on ultrasonic mirror image. METHODS: We used the mirror image associated with ultrasound during plaque brachytherapy to determine intraobserver reproducibility and interobserver agreement between two surgeons. 230 eyes with primary uveal melanoma were included in a retrospective analysis to determine the distance from the plaque to the tumour base using ultrasound...

A 19-year-old man noticed blurred vision in his right eye. He had an intraocular pressure (IOP) of 60 mmHg, versus 12 mmHg in the fellow eye. He was initially diagnosed with an atypical, advanced pigmentary glaucoma. The IOP did not respond to maximal medication, deep sclerectomy, goniopuncture, and two cyclophotocoagulations. Sixteen months after presentation, malignancy was first suspected, and the eye was enucleated. A ring melanoma of the anterior chamber angle was confirmed by the histopathological examination...

Primary malignant melanoma of the gallbladder is a rare disease, and 37 cases have been reported in the literature.The current patient was a 78-year-old man who was admitted with a pelvic tumor and left leg edema due to compression of the external iliac vein by the pelvic tumor.The edema improved following resection of the tumor, which was diagnosed at pathology as a malignant melanoma.After surgery, the patient became anorexic and complained of discomfort in the upper right abdomen.A whole body FDG-PET scan demonstrated significant uptake in the gallbladder and in the lymph nodes of the lower abdomen...

Melanoma is known as the most dangerous form of skin cancer; whereas the malignant choroidal melanoma is an orphan disease known as the most common primary intraocular malignancy in adults. Literature suggests that the consumption of garlic and/or mistletoe leads to a reduced risk of developing cancer. The obtained microstructures present sizes between 1.05 and 2.60 μm and Zeta potentials between -7 and +36 mV. A good encapsulation was observed on different evaluations (88-92%). It was determined that approx...

PURPOSE: Evisceration can be performed for blind, painful eyes. This surgery can promote the dissemination of tumor cells within the orbit if an ocular tumor has been missed preoperatively. METHODS: We reviewed the medical records of patients who were eviscerated for blind, painful eyes between 2009 and 2014 and who were referred after the surgery to the Institut Curie or the Rothschild Foundation in Paris. We included the patients with a histological diagnosis of ocular tumor or orbital recurrence...

Primary orbital melanoma is rare and has varied initial presentation. A 28-year-old female presented with proptosis and decreased vision in the left eye. Computed tomography scan showed an orbital mass with contrast enhancement and calcification around the optic nerve leading to a diagnosis of meningioma. The patient chose to be on observation. Loss of vision with an increase in proptosis was seen at 6 months follow-up. On surgical exploration, a well-defined pigmented mass was seen encasing the optic nerve...

We compare outcomes following radiotherapeutic and surgical management of iris melanoma. Endpoints included local tumor recurrence, metastases, and common complications. From an initial search that yielded 231 articles, we found 17 relevant studies with 761 eyes. The gender distribution was balanced with a mean age of 52 years. Most studies focused on either proton beam (49.4%) or plaque (31.4%) radiotherapy. Rates of local recurrence (range: 0-8%) and metastatic development (0-5%) were favorable following radiotherapy; however, common complications included cataract (36-73%), glaucoma (3-92%) and corneal conditions (0-33%)...
