Several nomenclature and grading systems have been proposed for conjunctival melanocytic intraepithelial lesions (C-MIL). The fourth "WHO Classification of Eye Tumors" (WHO-EYE04) proposed a C-MIL classification, capturing the progression of noninvasive neoplastic melanocytes from low- to high-grade lesions, onto melanoma in situ (MIS), and then to invasive melanoma. This proposal was revised to the WHO-EYE05 C-MIL system, which simplified the high-grade C-MIL, whereby MIS was subsumed into high-grade C-MIL. Our aim was to validate the WHO-EYE05 C-MIL system using digitized images of C-MIL, stained with hematoxylin and eosin and immunohistochemistry. However, C-MIL cases were retrieved from 3 supraregional ocular pathology …

Intrinsic Disorder In Prame And Its Role In Uveal Melanoma, Michael Antonietti, David J. Taylor Gonzalez, Mak Djulbegovic, Guy W. Dayhoff, Vladimir N. Uversky, Carol L. Shields, Carol L. Karp

Wills Eye Hospital Papers

Introduction

The PReferentially expressed Antigen in MElanoma (PRAME) protein has been shown to be an independent biomarker for increased risk of metastasis in Class 1 uveal melanomas (UM). Intrinsically disordered proteins and regions of proteins (IDPs/IDPRs) are proteins that do not have a well-defined three-dimensional structure and have been linked to neoplastic development. Our study aimed to evaluate the presence of intrinsic disorder in PRAME and the role these structureless regions have in PRAME( +) Class 1 UM.

Methods

A bioinformatics study to characterize PRAME’s propensity for the intrinsic disorder. We first used the AlphaFold tool to qualitatively assess the …

Wills Eye Hospital Papers

Over the past two decades, we have witnessed the increasing use of photodynamic therapy (PDT) in the field of ocular oncology. Based on a review of the literature and our own experience, we herein review the role of PDT for the management of intraocular tumors. The discussion includes two main topics. First, we discuss the application of PDT for benign tumors, including circumscribed choroidal hemangioma, choroidal osteoma, retinal astrocytoma, retinal capillary hemangioma (retinal hemangioblastoma), and retinal vasoproliferative tumor. Second, we assess the role of PDT for malignant tumors, including choroidal melanoma and choroidal metastasis.

Clinical Features, Pathology, And Surgical Management Of Periocular Giant Basal Cell Carcinoma, Oxana Madalina Grosu, Vladimir Poroch, Natalia Velenciuc, Sorinel Lunca

Journal of Mind and Medical Sciences

Objectives. Basal cell carcinomas (BCCs) are malignant tumors which rarely metastasize, are slow-growing, and extensively locally destructive. BCCs more than 5 cm in diameter are defined as giant. Most often they arise as a result of neglect, as the patient avoids, delays, or refuses to see a doctor. The large tumor diameter and consequently of the post-excisional defect make these lesions difficult to treat surgically with respect to selecting the surgical reconstruction technique. Method. We studied a group of 9 patients, aged 60 to 85 years, diagnosed with giant basal cell carcinomas (GBCCs) with periocular location in which surgery was …

Changes In Ultraviolet Radiation Exposure To The Ocular Region: A Population-Based Study., Ezekiel Weis, Sebastian Q. Vrouwe, David B. Lebaron, Matthew B. Parliament, Jerry A Shields, Carol L. Shields

Wills Eye Hospital Papers

In contrast to the well-established association between ultraviolet radiation (UVR) exposure and skin cancers, the relationship between UVR and uveal malignant melanoma (UM) remains controversial. To address this controversy, we evaluated the incidence rates of cutaneous malignancies in the eyelids as a proxy for UVR exposure in the ocular region using a population-based cancer registry. Overall, 74,053 cases of eyelid basal cell carcinoma (BCC) and 7890 cases of melanoma over a 26-year period (1982–2007) were analyzed. The incidence of eyelid basal cell carcinoma and uveal melanoma remained stable, whereas other cutaneous areas demonstrated an increase in the rates. A comparability …

Bilateral Acute Ocular Ischemic Syndrome Following Head And Neck Radiation, Dipali Nemade, Paul Ferguson, Vikram Shivkumar, Dennis Cole

Marshall Journal of Medicine

Previous literature has established a clear correlation between radiation therapy (RT) to the head and neck leading to aggressive atherosclerosis of the carotid arteries and subsequent increased risk for ischemic stroke. Stenosis of carotid arteries can lead to Ocular Ischemic syndrome (OIS). We present a case of acute bilateral OIS following head and neck RT for left tonsillar squamous cell carcinoma (SCC) in a 64 year-old Caucasian male. Routine large vessel cerebrovascular screening following head and neck radiotherapy should be considered as a means of potentially mitigating future stroke risk through initiation of medical therapy and interventional modalities as a …

Comparison Of Germline Versus Somatic Bap1 Mutations For Risk Of Metastasis In Uveal Melanoma., K. G. Ewens, E. Lalonde, J. Richards-Yutz, C. L. Shields, A. Ganguly

Wills Eye Hospital Papers

BACKGROUND: Germline mutations in BAP1 have been associated with BAP1-Tumor Predisposition Syndrome (BAP1-TPDS), a predisposition to multiple tumors within a family that includes uveal melanoma (UM), cutaneous melanoma, malignant mesothelioma and renal cell carcinoma. Alternatively, somatic mutations in BAP1 in UM have been associated with high risk for metastasis. In this study, we compare the risk of metastasis in UM that carry germline versus somatic BAP1 mutations and mutation-negative tumors.

METHODS: DNA extracted from 142 UM and matched blood samples was sequenced using Sanger or next generation sequencing to identify BAP1 gene mutations.

RESULTS: Eleven of 142 UM (8%) carried …

Introduction

Radiation therapy is often used for tumors of the optic nerve. The challenge with irradiating tumors surrounding structures associated with the eye is the risk of exposing the optic nerve, or other structures important to maintaining vision to potentially damaging radiation.

Fractionated stereotactic radiotherapy (FSRT) is commonly used for the treatment of optic nerve sheath meningiomas (ONSMs) for vision preservation. However, long term visual data in the literature is limited. We investigated visual outcomes in 27 patients with ONSMs after FSRT.

Choroidal Metastasis From Leiomyosarcoma In Two Cases, Eric Feinstein, Swathi Kaliki, Carol L Shields, Hormoz Ehya, Jerry A Shields

Wills Eye Hospital Papers

Leiomyosarcoma is a malignant tumor of mesenchymal cells and is the most common soft-tissue sarcoma. Leiomyosarcoma is a notably rare tumor in the ophthalmic region and can be of primary, secondary or metastatic origin. To the best of our knowledge, there has only been one published case of leiomyosarcoma metastasis to the choroid. In this case study, we report two cases of primary leiomyosarcoma with metastasis to the choroid of the eye. Both cases displayed systemic metastasis and showed response to high dose plaque radiotherapy. Despite its prevalence as the leading form of sarcoma, leiomyosarcoma rarely metastasizes to the ocular …

Breast Cancer Medications And Vision: Effects Of Treatments For Early-Stage Disease, Alvin Eisner, Shiuh-Wen Luoh

Community Health Faculty Publications and Presentations

This review concerns the effects on vision and the eye of medications prescribed at three phases of treatment for women with early-stage breast cancer (BC): (1) adjuvant cytotoxic chemotherapy, (2) adjuvant endocrine therapy, and (3) symptomatic relief. The most common side effects of cytotoxic chemotherapy are epiphora and ocular surface irritation, which can be caused by any of several different regimens. Most notably, the taxane docetaxel can lead to epiphora by inducing canalicular stenosis. The selective-estrogen-receptor-modulator (SERM) tamoxifen, long the gold-standard adjuvant-endocrine-therapy for women with hormone-receptor-positive BC, increases the risk of posterior subcapsular cataract. Tamoxifen also affects the optic nerve …
