Article Synopsis
  • The study aimed to analyze high-risk histopathological features in eyes with retinoblastoma (RB) after enucleation and compare patient outcomes globally.
  • A total of 1,426 RB cases were reviewed, revealing significant differences in histopathological features across continents, with Asia showing the highest rates of massive choroidal invasion and optic nerve invasion.
  • The findings indicated that patients from South America and Asia faced greater risks of tumor recurrence, systemic metastasis, and mortality compared to those from Australia, Europe, and North America.

Objective: Ruthenium-106 brachytherapy is commonly used to treat uveal melanomas. Most centres prescribe a radiation dose to the tumour apex that is calculated with the tumour located in the centre of the plaque. Recent work suggests that D-the minimum radiation dose delivered to 99% of tumour volume-may be a better predictor of tumour control than apex dose.

Purpose: Ruthenium-106 brachytherapy is a common treatment for small to medium-sized uveal melanomas. In certain clinical contexts, plaques may be placed eccentrically to tumor center. The effect of plaque decentration, a common radiation dose measurement in radiotherapy: D, the percentage of the tumor volume receiving at least 98% of the prescribed dose (a commonly used term in radiation oncology), is unknown.

We describe the case of a 76-year-old man who developed an asymptomatic choroidal osteoma in the left eye 10 years after receiving retinal laser photocoagulation for treatment of a peripapillary choroidal neovascular membrane. The choroidal osteoma presented as a progressively enlarging, well-circumscribed yellow lesion adjacent to the region of retinal fibrosis. Optical coherence tomography showed a choroidal lesion with superficial lamellations and ultrasonography demonstrated increased echogenicity.

Significance: These cases highlight the importance of monitoring choroidal nevi with benign imaging characteristics and the potential to quantify horizontal growth using optical coherence tomography (OCT), in the absence of color fundus photography.

Purpose: This study aimed to present reports of two patients with pigmented choroidal tumors with low malignant potential based on their multimodal imaging features at the time of referral, but access to prior OCT imaging confirmed horizontal growth consistent with melanoma.

Case Reports: Two patients with pigmented, dome-shaped, subfoveal tumors were referred.

Primary choroidal lymphoma is a rare, slowly progressive intraocular malignancy. Most are low grade B cell lymphomas, often involving tissues adjacent to the choroid such as the subconjunctival space, lacrimal gland or orbit. Ideally, these lesions are biopsied to establish histopathological diagnosis.

Clinical Relevance: Although melanocytic choroidal tumours of the choroid are a common eye pathology, no standardised protocol exists for their management in the community.

Background: Choroidal naevi are found in approximately 6% of the adult White population, whereas choroidal melanomas are rare, with an annual incidence of 5-10/million/year. Multimodal imaging has advanced the understanding of malignancy imaging biomarkers, but distinguishing between a small melanoma and naevus remains difficult and an algorithm for their management by community practitioners has not been uniformly adopted.

Background: To assess the long-term visual outcomes in patients with posteriorly located choroidal melanoma treated with ruthenium plaque brachytherapy between January 2013 and December 2015.

Methods: A retrospective review was conducted on consecutive patients treated with ruthenium plaque brachytherapy for post-equatorial choroidal melanoma with available Snellen visual acuity before and after treatment, and the development and treatment of radiation complications.

Results: There were 219 patients with posterior choroidal melanoma treated with ruthenium plaque brachytherapy.

Objective: The aim of this study was to determine the sensitivity and specificity of the MOLES scoring system in differentiating choroidal melanomas from nevi according to Mushroom shape, Orange pigment, Large tumor size, Enlarging tumor, and Subretinal fluid (SRF).

Methods: Color photographs, fundus-autofluorescence images, and optical coherence tomography of 222 melanocytic choroidal tumors were reviewed. Each MOLES feature was retrospectively scored between 0 and 2 and tumors categorized as "common nevus," "low-risk nevus," "high-risk nevus," and "probable melanoma" according to the total score.

Objective: To define the characteristics of solitary idiopathic choroiditis (SIC) in a consecutive series of patients and propose a nomenclature change to idiopathic scleroma.

Materials And Methods: Electronic patient records were retrospectively interrogated to identify all patients diagnosed with SIC between 2002 and 2019 in a tertiary referral ophthalmic hospital in the United Kingdom.

Results: Thirty-four eyes of 34 patients were found to have SIC.

: The malignant potential of choroidal melanocytic tumours detected incidentally in the community is thought to be low, but this has not been assessed using a validated screening tool. An accurate characterisation of the malignant potential of these lesions has implications for resource allocation, service provision, education, and training.: MOLES (Mushroom shape, Orange Pigment, Large size, Enlargement, and Subretinal fluid) categorises tumours as 'common naevus', 'low-risk naevus', 'high-risk naevus', and 'probable melanoma'.

Purpose: To report local disease control and all-cause mortality in patients with extraocular extension (EOE) of uveal melanoma undergoing enucleation followed by observation or external beam radiotherapy (EBRT).

Methods: Charts of patients enucleated between January 1, 1997 and December 31, 2019, with histopathological evidence of EOE of uveal melanoma were reviewed.

Results: The cohort comprised 51 patients with a mean age of 67 ± 15 years, 22 (43%) of whom underwent adjuvant postenucleation EBRT.

We report a 61-year-old female who presented to our service with recent growth of a thickened, pigmented, sub-conjunctival lesion within an area of ocular melanocytosis in her left eye. Lamellar sclerectomy was performed. Histopathological assessment revealed a localized melanocytic proliferation with features of blue nevus arising within the area of ocular melanocytosis.

To determine if ultrasonography is necessary to detect progression of choroidal melanocytic tumors undergoing sequential multi-modal imaging with color photography, autofluorescence (AF) and optical coherence tomography (OCT). All patients with choroidal melanoma undergoing treatment at Moorfields Eye Hospital between January 2016 and March 2020 were reviewed to identify those with treatment deferred by ≥2 months. Tumors that showed progression prior to treatment, defined as an increase in (a) basal dimensions (b) thickness (c) orange pigment and/or (d) sub-retinal fluid, were included.

Background And Objective: Circumscribed choroidal haemangioma (CCH) has several characteristic clinical and angiographic features. We aimed to compare indocyanine green angiography (ICG) findings of CCH captured on a traditional digital camera system (DCS) to newer scanning laser ophthalmoscopy (SLO) platforms.

Study Design/materials And Methods: A total of 35 patients over a 10-year period diagnosed with CCH using ICG were included (18 imaged with DCS and 17 with SLO).

Purpose: To evaluate the MOLES system for identifying malignancy in melanocytic choroidal tumors in patients treated for choroidal melanoma.

Methods: Records of 615 patients treated for choroidal melanoma between January 2017 and December 2019 were reviewed. Patients were excluded if iris and/or ciliary body involvement (106 patients), inadequate fundus photography (26 patients), no images available for review (21 patients) and/or treatment was not primary (11 patients).

Background: To evaluate the safety and efficacy of a treat-and-extend protocol of aflibercept for cystoid macular oedema (CMO) secondary to central retinal vein occlusion (CRVO).

Methods: Twenty patients with CMO secondary to CRVO were included in this prospective cohort study. After 3 loading 4-weekly injections, treatment intervals were increased by 2 weeks if there was no clinical activity, to a maximum of 12 weeks.

Ocular surface squamous neoplasia is the most common tumour of the ocular surface. It is a spectrum of disease from intraepithelial dysplasia to invasive squamous cell carcinoma. Recent years have seen an increase in the use of topical chemotherapeutic agents to treat this condition, often as primary treatment without full-thickness biopsy.
