Purpose: Conjunctival squamous cell carcinoma (SCC), a type of ocular surface neoplasia, is primarily treated by surgical resection and topical immuno- or chemotherapy. Metastatic disease may be with systemic chemo- immunotherapy, albeit variable response. The purpose this study was to determine whether immune checkpoint blockade might considered in the management conjunctival SCC. Methods: In retrospective study, we evaluated tumor programmed death-ligand 1 (PD-L1) expression, high-risk...
The eyelids are complex structures composed of various tissues. As such, a wide array lesions exist that affect the eyelids. Clinical diagnosis these is essential to differentiate benign from malignant ones. Although accurate, some cases misdiagnosed. Histopathology remains crucial step in final eyelid lesions. objective study describe and compare clinicopathological tumours between two tertiary care centers, one South America other North America, 2010 2019. We reviewed 1 935 at McGill...
Information regarding risk of metastasis and disease-related death (DD) from conjunctival squamous cell carcinoma (SCC) is relatively scarce. We explored prognostic factors for orbital exenteration, local recurrence, nodal metastasis, DD in patients with SCC.Retrospective cross-sectional study.All consecutive SCC treated by the senior author at MD Anderson Cancer Center during1999-2018 were included. Survival curves estimated using Kaplan-Meier method, survival differences assessed 2-sided...
The current case presentation highlights the potential of cemiplimab, a programmed cell death protein-1 (PD-1) inhibitor, as first-line treatment for periocular metastatic cutaneous squamous carcinoma (SCC) without requiring curative surgery or radiotherapy. A 64-year-old male presented with progressing 4.5 × 3.0 cm left upper eyelid lesion initially diagnosed psoriasis. Work-up revealed SCC tumor invasion into extraconal fat and lacrimal gland, metastasis to parotid lymph node. patient also...
To study the multidisciplinary management and survival outcomes of orbital metastasis (OM).All patients with a diagnosis OM treated during 1999-2019 were included. Clinical data retrospectively collected analyzed.The included 118 patients, 71 females 47 males, median age 61 years. The most common primary tumor types breast carcinoma (43 patients), melanoma (17), lung (13), thyroid (7), renal cell (6), neuroendocrine (6). Ninety-six had known history cancer at diagnosis. time from to was 31...
After blunt trauma from a ball or fist, fall motor vehicle collision, the floor of orbit can fracture without involving orbital rim other facial bones. This may occur because marked pressure rise within when globe is suddenly displaced posteriorly (hydraulic theory
Abstract Background To describe the clinical presentation, treatment, and overall prognosis in eight patients with primary Ewing's sarcoma (ES) involving orbit. Methods A retrospective interventional study of all biopsy‐proven cases ES orbit was done. Results There were seven males one female a median age 14 years. Imaging showed osseous involvement extraorbital extension four. Complete tumor resection done four, partial three, biopsy followed by sinus surgery one. EWSR1 gene rearrangement...
Ocular trauma accounts for 8% of emergency department visits; these, 31% involve corneal foreign bodies.[1][1] A focused history includes presenting symptoms, type body, penetrability, entry velocity, duration since injury, concurrent contact lens usage and ocular history.[1][1]
Minoxidil, a drug that is widely used for hair loss treatment, considered safe medication. While there are minor side-effects such as scalp irritation or systemic effects like tachycardia, it rarely associated with severe ocular complications. We report case where 35-year-old man, taking oral Minoxidil alopecia, developed Central Retinal Vein Occlusion (CRVO) Cilioretinal Artery (CLRAO), leading to sudden vision loss. After discontinuation, the patient’s significantly improved. This incident...
Enhancing the accessibility of ophthalmology webpages can help individuals with vision access needs obtain essential appointment information, educational resources, and available ophthalmic services. This study evaluated these for patients visual impairment color deficiencies. Retrospective cross-sectional study. In February 2024, Web Content Accessibility Guidelines 2.0 (WCAG 2.0) were used to assess web homepages top-ranked institutes in United States using three evaluation tools:...
Orbital inflammatory disease (OID) is an condition of the orbital and periorbital region. This case reports suspected Lyme neuroborreliosis underlying initial presentation OID in a 37-year-old male. Myositis was confirmed by computed tomography (CT) imaging. Cranial neuritis third, fifth, seventh cranial nerves evidenced magnetic resonance imaging (MRI). Serology positive for
Purpose We descriptively and comparatively evaluated the comprehensiveness of Canadian US-accredited ophthalmology residency program websites as August 28, 2024.
Purpose: Retinoblastoma (RB) is the most common intraocular cancer and associated with lifelong risks of developing a second primary cancer, especially in patients hereditary RB and/or childhood exposure to radiotherapy. Methods: The study included all consecutive history treated for during 1994–2018. Patient demographics characteristics were examined. associations among radiation or chemotherapy as treatment RB, unilateral versus bilateral status, types multiplicity cancers, survival after...
