Retinoblastoma, the primary ocular malignancy in pediatric patients, poses a substantial threat to mortality without prompt and effective management. The prognosis for survival and preservation of visual acuity hinges upon the disease severity at the time of initial diagnosis. Notably, retinoblastoma has played a crucial role in unraveling the genetic foundations of oncogenesis. The process of tumorigenesis commonly begins with the occurrence of biallelic mutation in the RB1 tumor suppressor gene, which is then followed by a cascade of genetic and epigenetic alterations that correspond to the clinical stage and pathological features of the tumor...

In this review, we aim to provide an overview of the five most common malignant eyelid tumors with current treatment recommendations based on international guidelines. Particular attention is paid to the clinicopathological correlation and the update with regard to adequate treatment. Newer systemic therapies enrich the existing treatment options, of which complete tumor excision remains the most important therapeutic measure.

Masquerade syndromes in uveitis are complex clinical conditions where non-inflammatory diseases mimic uveitic manifestations, often leading to diagnostic and therapeutic challenges. This review delves into the diverse spectrum of masquerade syndromes, categorizing them into neoplastic and non-neoplastic entities. We explore the prevalence of primary intraocular lymphoma, leukaemia, retinoblastoma, and other malignancies, as well as conditions like retinitis pigmentosa and endophthalmitis that can present as uveitis...

PURPOSE: Intravascular large B-cell lymphoma (IVLBCL) is an extremely rare, aggressive, multi-system disease that can affect the eye. We describe the ophthalmic presentation, multimodal imaging and treatment response of uveal IVLBCL. METHODS: Review and case report. RESULTS: Twenty-five published cases of IVLBCL involving the eye including our own were identified. Of these, 15 patients (60%) had clinically-detectable intraocular involvement, 6 (24%) had extraocular ophthalmic involvement only and 4 (16%) had subclinical, undiagnosed intraocular involvement that was retrospectively detected on post-mortem ocular histopathology...

IMPORTANCE: Ocular surface squamous neoplasia (OSSN) is a spectrum of malignancies that generally includes conjunctival intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC). OSSN can be treated with topical therapies including interferon α-2b (IFN), mitomycin C (MMC), or 5-fluorouracil 1% (5FU). Recently, due to unavailability of IFN and toxicity associated with MMC, therapy has shifted towards 5FU. OBJECTIVE: Herein, we compare the use of 5FU 1% as a primary versus (vs) secondary treatment regimen in eyes with moderate to extensive OSSN...

INTRODUCTION: Magnetic resonance imaging (MRI) has demonstrated high levels of tissue contrast, accuracy and reproducibility in evaluating posterior uveal melanoma. Owing to smaller size, the role of MRI in detecting and characterising iris melanoma has not yet been explored. AIMS: To develop a protocol to image iris melanoma and describe the MRI characteristics of histopathological-confirmed iris melanoma. MATERIALS AND METHODS: An optimised MRI protocol, using a 3T MRI scanner and a 32-channel head coil, was developed to image iris tumours...

PURPOSE: To determine the correlation of Fitzpatrick Skin Type (FST) and iris color with tumor size (tumor thickness and basal diameter) in patients with uveal melanoma. DESIGN: Retrospective Cohort METHODS: Retrospective cohort from a single ocular oncology center of 823 patients with uveal melanoma and documented FST, iris color, and tumor size. Patients were classified by FST (type I, II, and III-V) and iris color (blue, green, and brown) on the basis of external facial photography...

Decades of studies on age-related macular degeneration (AMD), cardiovascular disease and stroke have not found consistent associations between AMD and systemic vascular disease. This study suggests that there is in fact no general relationship, but instead a strong, specific association between only the subretinal drusenoid deposit (SDD) phenotype of AMD on retinal imaging and certain co-existent vascular diseases that are high risk for compromised cardiac output or internal carotid artery stenosis. Future screening initiatives for these high -risk vascular diseases (HRVDs) with fast, inexpensive retinal imaging could make a significant contribution to public health and save lives...
