The Fight Tumour Blindness Registry: Efficient capture of high-quality real-world data in uveal melanoma.

OBJECTIVE: To describe the development of a web-based data collection tool to track the management and outcomes of uveal melanoma patients. DESIGN: Description of a clinical registry. PARTICIPANTS: Patients with uveal melanoma. METHODS: A panel of expert ocular oncologists, with input from other relevant specialties and individuals with expertise in registry development, collaborated to formulate a minimum data set to be collected to track patient centred, real-world outcomes in uveal melanoma. This data set was used to create the Fight Tumour Blindness! (FTB!) registry within Save Sight Registries. RESULTS: The data set to be collected includes patient demographics and medical history, baseline visit, follow-up visit including tumour treatment, metastatic staging and surveillance, pathology, and patient-reported questionnaires. The inbuilt mechanisms to ensure efficient and complete data collection are described. CONCLUSIONS: The FTB! registry can be used to monitor outcomes for patients with uveal melanoma. It allows benchmarking of outcomes and comparisons between different clinics and countries.

Assessment of Remote Training, At-Home Testing, and Test-Retest Variability of a Novel Test for Clustered Virtual Reality Perimetry.

OBJECTIVE: To assess the feasibility of remotely training glaucoma patients to take a 10-session clustered virtual reality (VR) visual field (VF) test (Vivid Vision Perimetry [VVP-10]) at home, analyze results for test-retest variability, and assess correspondence with conventional perimetry. DESIGN: Cross-sectional study. SUBJECTS: Twenty-one subjects with glaucoma were enrolled and included in the feasibility assessment of remote training. Thirty-six eyes were used for test-retest analysis and determination of concordance with the Humphrey Field Analyzer (HFA). METHODS: Subjects were provided with a mobile VR headset containing the VVP-10 test software and trained remotely via video conferencing. Subjects were instructed to complete 10 sessions over a 14-day period. MAIN OUTCOME MEASURES: Feasibility was determined by the number of subjects who were able to independently complete VVP-10 over the 14-day period after 1 remote training session. The intraclass correlation coefficient (ICC) for average fraction seen across 10 sessions and the standard error (SE) of the mean were primary outcome measures for assessing test-retest variability. Correlation with HFA mean sensitivity (MS) across eyes, was a secondary outcome measure. RESULTS: Twenty subjects (95%) successfully completed the VVP-10 test series after 1 training session. The ICC for VVP-10 was 0.95 (95% confidence interval [CI], 0.92-0.97). The mean SE in units of fraction seen was 0.012. The Spearman correlations between VVP-10 average fraction seen and HFA MS were 0.87 (95% CI, 0.66-0.98) for moderate-to-advanced glaucoma eyes, and decreased to 0.67 (95% CI, 0.28-0.94) when all eyes were included. CONCLUSIONS: Remote training of patients at home is feasible, and subsequent remote clustered VF testing using VVP-10 by patients on their own, without any further interactions with caregivers or study staff, was possible. At-home VVP-10 results demonstrated low test-retest variability. Future studies must be conducted to determine if VVP-10, taken at home as convenient for the patient, may be a viable supplement to provide equivalent or complementary results to that of standard in-clinic assessment of visual function in glaucoma.

Adenoma of the nonpigmented ciliary epithelium presenting as glaucoma.

Purpose: We describe a case of adenoma of the nonpigmented ciliary epithelium in a 58-year-old male, who presented with glaucoma. Observations: A healthy White male was incidentally found to have an elevated intraocular pressure in his left eye (25 mmHg) during a visit to a local optometrist. After further investigations he was diagnosed with a primary open angle glaucoma (POAG) and treated with drops for two years until he developed a sectorial cataract. During the first dilated eye exam, a pale tan tumor was discovered, that seemed to originate from the superior ciliary body, causing a sectorial-cortical cataract and subluxation of the lens. The eye was enucleated on the suspicion of a rare adult medulloepithelioma, because of multicystic features on B-scan ultrasonography. However, histopathological examination revealed an adenoma of the nonpigmented ciliary epithelium that grew in trabecular papillary patterns, with smaller areas of solid and microcystoid growth. As this is a benign tumor without metastatic potential, the patient was referred back to his home clinic without requirement for radiological staging or screening. Conclusion and Importance: Adenomas of the nonpigmented ciliary epithelium (NPCE adenomas) are benign tumors that are often mistaken for malignant counterparts. Thus, this case report expands on the available literature of this rare entity.

Long-term visual outcomes after ruthenium plaque brachytherapy for posterior choroidal melanoma.

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. Median follow up was 56.5 months, range 12-81 months. Final visual acuity was ≥6/12 in 97 (44.3%) patients, 6/12 to 6/60 in 57 (26.0%), <6/60 in 55 (25.1%) and 10 (4.6%) eyes were enucleated. Radiation maculopathy was the most common radiation complication encountered, occurring in 53 (24.2%) patients. Of these, final visual acuity was 6/12 in 10 patients (18.9%), 6/12 to 6/60 in 26 (49.1%), <6/60 in 16 (30.2%) and 1 eye (1.9%) was enucleated. Twenty-five (47%) with radiation maculopathy were treated with intravitreal anti-angiogenic therapy, 27 (51%) were monitored and one (2%) was treated with scatter photocoagulation. Eyes treated with intravitreal anti-angiogenic therapy had better final vision than those observed or treated with retinal laser (chi-square, p = 0.04). On multivariate analysis, close proximity to the optic nerve and fovea, and large or notched plaque type was associated with final vision worse than 6/12. CONCLUSION: Most patients treated with ruthenium plaque brachytherapy for posterior choroidal melanoma retain 6/60 vision, with almost half retaining 6/12 vision at long term follow up.

The MOLES system to guide the management of melanocytic choroidal tumours: can optometrists apply it?

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. One of the authors (BD) devised the MOLES scoring system, which indicates malignancy likelihood according to mushroom shape, orange pigment, large size, enlargement, and subretinal fluid. When applied by ocular oncologists, the system accurately distinguishes choroidal naevi from melanomas. The aim of this study was to evaluate whether community optometrists can appropriately manage patients with melanocytic choroidal tumours using this system. METHODS: Clinical images of 25 melanocytic choroidal tumours were presented in an online survey, including colour fundus photographs, fundus autofluorescence, optical coherence tomography, and B-scan ultrasound images. Using the MOLES system, 39 optometrists diagnosed tumours as naevus or probable melanoma and decided between community monitoring and ophthalmologist referral. Responses were compared to MOLES grading of the same clinical images by ocular oncologists. RESULTS: Using MOLES, optometrists correctly identified 389/406 probable melanomas (95.8% sensitivity) and 331/516 choroidal naevi (64.1% specificity); correctly referred 773/778 tumours to an ophthalmologist (99.4% sensitivity); and correctly managed 80/144 lesions (55.6% specificity) in the community. CONCLUSION: Optometrists safely applied the MOLES scoring system in this survey. Further measures are indicated to reduce choroidal naevi over-referral and evaluate MOLES system usage in clinical optometric practice, where some imaging modalities may not be readily available.

Can the MOLES acronym and scoring system improve the management of patients with melanocytic choroidal tumours?

It can be difficult for practitioners to determine the likelihood of malignancy in melanocytic choroidal tumours. This author has therefore devised the MOLES acronym to highlight the most informative clinical features, which comprise mushroom shape, orange pigment, large size, enlargement, and subretinal fluid. Each of these is scored 0 if absent, 1 if subtle or uncertain, and 2 if present. Tumours are categorised as 'common naevus', 'low-risk naevus', 'high-risk naevus' and 'probable melanoma' according to whether the sum of these five scores is 0, 1, 2 or 3 or more, respectively. Tentative recommendations, subject to future studies, include: review of 'common naevi' by a community optometrist whenever the patient attends for another reason, such as a two-yearly 'check-up' (i.e., 'self-care'); non-urgent referral of patients with 'low-risk naevi' or 'high-risk naevi' to an ophthalmologist to plan long-term surveillance (i.e., determining the frequency of assessments and whether these should be undertaken by an ophthalmologist or a community optometrist); and urgent referral of patients with a MOLES score >2 (i.e., 'probable melanoma') to an ophthalmologist for immediate referral to an ocular oncologist if a suspicion of malignancy is confirmed. The MOLES system does not require assessment of internal acoustic reflectivity by ultrasonography. MOLES scores correlate well with diagnosis of choroidal naevi and melanomas by ocular oncologists; however, further evaluation of this aid in routine optometric practice and other situations is needed. MOLES should prevent unnecessary referral of patients with naevi for second opinion and non-essential monitoring of these patients at hospital eye services.

Outcome Measures of New Technologies in Uveal Melanoma: Review from the European Vision Institute Special Interest Focus Group Meeting.

Uveal Melanoma (UM) is the most common primary intra-ocular tumor in adults. New diagnostic procedures and basic science discoveries continue to change our patient management paradigms. A recent meeting of the European Vision Institute (EVI) special interest focus group was held on "Outcome Measures of New Technologies in Uveal Melanoma", addressing the latest advances in UM, starting with genetic developments, then moving on to imaging and treatment of the primary tumor, as well as to investigating the most recent developments in treating metastases, and eventually taking care of the patient's wellbeing. This review highlights the meeting's presentations in the context of the published literature.

Detecting Progression of Treated Choroidal Melanomas: Is Ultrasonography Necessary?

Prompt detection and treatment of local treatment failure after radiotherapy for choroidal melanoma optimises any opportunities for conserving vision and the eye, possibly reducing an increased risk of metastatic disease. Long-term surveillance is therefore required but is hampered by the perceived need to perform ultrasonography, which may not be available at a patient's local hospital. The aim of this study was to determine whether local treatment failure can reliably be detected with colour fundus photography alone, and, if so, in which patients. Patients were included in the study if diagnosed with local treatment failure between April 2016 and February 2021 after eye-conserving therapy for choroidal melanoma. Wide-field colour and fundal autofluorescence (FAF) images, optical coherence tomography (OCT), and ultrasonography (US) were analysed by two of the authors (GN and UH). The cohort included 87 patients with local treatment failure. In 75 patients with clear media, tumour progression was detected by colour photography alone in 74 (98.7%) patients. Sensitivity was not increased by the addition of either OCT or AF. One patient with clear media developed extraocular extension detected with US without visible change in the intraocular part of the tumour. In the other 12 patients, US was required because of opaque media and a consequently poor fundal view. Local treatment failure after radiotherapy for choroidal melanoma is detected in 98.7% of cases with colour photography when the media are clear. Ultrasonography is useful when photography is prevented by opaque media or tumours having locations in the far periphery.

Small High-Risk Uveal Melanomas Have a Lower Mortality Rate.

Our aim was to determine whether size impacts on the difference in metastatic mortality of genetically high-risk (monosomy 3) uveal melanomas (UM). We undertook a retrospective analysis of data from a patient cohort with genetically characterized UM. All patients treated for UM in the Liverpool Ocular Oncology Centre between 2007 and 2014, who had a prognostic genetic tumor analysis. Patients were subdivided into those with small (≤2.5 mm thickness) and large (>2.5 mm thickness) tumors. Survival analyses were performed using Gray rank statistics to calculate absolute probabilities of dying as a result of metastatic UM. The 5-year absolute risk of metastatic mortality of those with small monosomy 3 UM was significantly lower (23%) compared to the larger tumor group (50%) (p = 0.003). Small disomy 3 UM also had a lower absolute risk of metastatic mortality (0.8%) than large disomy 3 UM (6.4%) (p = 0.007). Hazard rates showed similar differences even with lead time bias correction estimates. We therefore conclude that earlier treatment of all small UM, particularly monosomy 3 UM, reduces the risk of metastatic disease and death. Our results would support molecular studies of even small UM, rather than 'watch-and-wait strategies'.

Cost-utility analysis of a decade of liver screening for metastases using the Liverpool Uveal Melanoma Prognosticator Online (LUMPO).

This paper outlines a method for cost-utility analysis of liver screening for metastases in patients with posterior uveal melanoma (UM). A semiparametric model of the cumulative incidence of onset of liver metastases was fitted to a retrospective data set of 615 subjects with clinical follow-up with respect to liver surveillance imaging and outcome. The model was internally validated via bootstrap resampling in terms of its discrimination and calibration performance. Receiver operating characteristics (ROC) were derived at different time points. The discrimination performances are consistent across time. The area under the ROC curve at 5 years post treatment was 0.85 [95% CI: 0.81-0.88]. A goodness-of-fit test gives χ2(10)=5.3,p=0.9 demonstrating no evidence against the null hypothesis of zero difference between observed and expected onset of metastatic events. Results showed that at 80% sensitivity, 87% of UM patients will avoid unnecessary radiological scans. This provides potential cost savings of between £46,000 and £97,000 per year to the National Health Service assuming 600 new cases per year.

Detecting Progression of Melanocytic Choroidal Tumors by Sequential Imaging: Is Ultrasonography Necessary?

Purpose: 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). Methods: 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. Mushroom shape, Orange pigment, Large size, Enlargement and Sub-retinal fluid (MOLES) scores were assigned to all tumors at earliest date and date of treatment. Results: A total of 99 patients with a mean age of 66 years (range: 26-90) were included. The initial MOLES score was 1 in 2 cases, 2 in 23 cases, and ≥3 in 74 cases. Progression was detected with sequential color photography alone in 100% of MOLES 1/2 and 97% of lesions with a MOLES score of ≥3. When findings on AF and OCT were included, sensitivity for detecting subtle change without ultrasonography improved to 100% for MOLES 3 and 97% for MOLES 4/5. Only one patient included in this study had an isolated increase in thickness that may have been missed had sequential ultrasonography not been performed. Overall, the sensitivity for detecting progression with color photographs alone was 97% (95% CI 93-100%) and increased to 99% (95% CI 97-100%) by including autofluorescence and OCT. Conclusions: Monitoring of choroidal nevi, particularly those classified as MOLES 1 or 2 (i.e., low-risk or high-risk naevi), can be accomplished safely without the need for ultrasonography. The findings of this study may remove barriers to the implementation of tele-oncology clinics for the monitoring of choroidal melanocytic tumors.

Uveal melanoma.

Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. UMs are usually initiated by a mutation in GNAQ or GNA11, unlike cutaneous melanomas, which usually harbour a BRAF or NRAS mutation. The annual incidence in Europe and the USA is ~6 per million population per year. Risk factors include fair skin, light-coloured eyes, congenital ocular melanocytosis, ocular melanocytoma and the BAP1-tumour predisposition syndrome. Ocular treatment aims at preserving the eye and useful vision and, if possible, preventing metastases. Enucleation has largely been superseded by various forms of radiotherapy, phototherapy and local tumour resection, often administered in combination. Ocular outcomes are best with small tumours not extending close to the optic disc and/or fovea. Almost 50% of patients develop metastatic disease, which usually involves the liver, and is usually fatal within 1 year. Although UM metastases are less responsive than cutaneous melanoma to chemotherapy or immune checkpoint inhibitors, encouraging results have been reported with partial hepatectomy for solitary metastases, with percutaneous hepatic perfusion with melphalan or with tebentafusp. Better insight into tumour immunology and metabolism may lead to new treatments.

Practice Considerations for Proton Beam Radiation Therapy of Uveal Melanoma During the Coronavirus Disease Pandemic: Particle Therapy Co-Operative Group Ocular Experience.

Uveal melanoma (UM) is a rare but life-threatening cancer of the eye. In light of the coronavirus disease (COVID-19) pandemic, hospitals and proton eye therapy facilities must analyze several factors to ensure appropriate treatment protocols for patients and provider teams. Practice considerations to limit COVID-19 transmission in the proton ocular treatment setting for UM are necessary. The Particle Therapy Co-Operative Group is the largest international community of particle/proton therapy providers. Participating experts have current or former affiliation with the member institutions of the Particle Therapy Co-Operative Group Ocular subcommittee with long-standing high-volume proton ocular programs. The practices reviewed in this document must be taken in conjunction with local hospital procedures, multidisciplinary recommendations, and regional/national guidelines, as each community may have its unique needs, supplies, and protocols. Importantly, as the pandemic evolves, so will the strategies and recommendations. Given the unique circumstances for UM patients, along with indications of potential ophthalmologic transmission as a result of health care providers working in close proximity to patients and intrinsic infectious risk from eyelashes, tears, and hair, practice strategies may be adapted to reduce the risk of viral transmission. Certainly, providers and health care systems will continue to examine and provide as safe and effective care as possible for patients in the current environment.

Choroidal melanoma overlying scleral buckle evading detection treated with proton beam radiotherapy.

PURPOSE: to present a case of a choroidal melanoma located along a scleral buckle contour and was successfully treated with proton beam radiotherapy, without disturbing the scleral buckle. OBSERVATIONS: A 60-year-old woman presented with photopsias and history of retinal detachment repair with scleral buckle 36 years prior. She had annual dilated exams with her ophthalmologist over the last several years. While initially diagnosis of choroidal detachment, hemorrhage and intraocular buckle intrusion were suspected, the patient was referred to an ophthalmic oncology center and choroidal melanoma was confirmed. The patient underwent tantalum marker placement, trans-retinal biopsy and proton beam radiotherapy. Despite no evidence of metastatic disease on systemic imaging, prognostic genetic testing of the tumor revealed high-risk alterations for future metastasis, and the patient enrolled in an adjuvant clinical trial. CONCLUSIONS: The location of this choroidal melanoma along a scleral buckle contour presented a unique therapeutic challenge. We successfuly treated the tumor with proton beam radiotherapy without disturbing the scleral buckle. IMPORTANCE: chorioretinal elevations adjacent a scleral buckle may be presumed to be due to the buckle element; ultrasound can be helpful in distinguishing an intraocular tumor. Proton beam radiotherapy has the advantage over plaque brachytherapy in this setting as removing the scleral buckle is not needed and placing a plaque over the scleral buckle risks altering the effective radiotherapy dose.

Next-Generation Sequencing of Retinoblastoma Identifies Pathogenic Alterations beyond RB1 Inactivation That Correlate with Aggressive Histopathologic Features.

PURPOSE: To determine the usefulness of a comprehensive, targeted-capture next-generation sequencing (NGS) assay for the clinical management of children undergoing enucleation for retinoblastoma. DESIGN: Cohort study. PARTICIPANTS: Thirty-two children with retinoblastoma. METHODS: We performed targeted NGS using the UCSF500 Cancer Panel (University of California, San Francisco, San Francisco, CA) on formalin-fixed, paraffin-embedded tumor tissue along with constitutional DNA isolated from peripheral blood, buccal swab, or uninvolved optic nerve. Peripheral blood samples were also sent to a commercial laboratory for germline RB1 mutation testing. MAIN OUTCOME MEASURES: Presence or absence of germline RB1 mutation or deletion, tumor genetic profile, and association of genetic alterations with clinicopathologic features. RESULTS: Germline mutation or deletion of the RB1 gene was identified in all children with bilateral retinoblastoma (n = 12), and these NGS results were 100% concordant with commercial germline RB1 mutation analysis. In tumor tissue tested with NGS, biallelic inactivation of RB1 was identified in 28 tumors and focal MYCN amplification was identified in 4 tumors (2 with wild-type RB1 and 2 with biallelic RB1 inactivation). Additional likely pathogenic alterations beyond RB1 were identified in 13 tumors (41%), several of which have not been reported previously in retinoblastoma. These included focal amplifications of MDM4 and RAF1, as well as damaging mutations involving BCOR, ARID1A, MGA, FAT1, and ATRX. The presence of additional likely pathogenetic mutations beyond RB1 inactivation was associated with aggressive histopathologic features, including higher histologic grade and anaplasia, and also with both unilateral and sporadic disease. CONCLUSIONS: Comprehensive NGS analysis reliably detects relevant mutations, amplifications, and chromosomal copy number changes in retinoblastoma. The presence of genetic alterations beyond RB1 inactivation correlates with aggressive histopathologic features.

Multicenter External Validation of the Liverpool Uveal Melanoma Prognosticator Online: An OOG Collaborative Study.

Uveal melanoma (UM) is fatal in ~50% of patients as a result of disseminated disease. This study aims to externally validate the Liverpool Uveal Melanoma Prognosticator Online V3 (LUMPO3) to determine its reliability in predicting survival after treatment for choroidal melanoma when utilizing external data from other ocular oncology centers. Anonymized data of 1836 UM patients from seven international ocular oncology centers were analyzed with LUMPO3 to predict the 10-year survival for each patient in each external dataset. The analysts were masked to the patient outcomes. Model predictions were sent to an independent statistician to evaluate LUMPO3's performance using discrimination and calibration methods. LUMPO3's ability to discriminate between UM patients who died of metastatic UM and those who were still alive was fair-to-good, with C-statistics ranging from 0.64 to 0.85 at year 1. The pooled estimate for all external centers was 0.72 (95% confidence interval: 0.68 to 0.75). Agreement between observed and predicted survival probabilities was generally good given differences in case mix and survival rates between different centers. Despite the differences between the international cohorts of patients with primary UM, LUMPO3 is a valuable tool for predicting all-cause mortality in this disease when using data from external centers.

THERAPEUTIC VITRECTOMY AS AN ADJUNCT TREATMENT TO SYSTEMIC CHEMOTHERAPY FOR INTRAOCULAR LYMPHOMA.

PURPOSE: To report the outcome of a previously vitrectomized eye having less lymphoma disease burden compared with the contralateral nonvitrectomized eye over the course of 3.5 years while on systemic chemotherapy. METHODS: Case report. RESULTS: A 51-year-old man with vitreoretinal lymphoma with central nervous system involvement underwent vitrectomy in his left eye. Over the following 3.5 years on systemic chemotherapy, the left eye had less lymphoma disease burden compared with the contralateral nonvitrectomized right eye. CONCLUSION: Therapeutic vitrectomy may be a useful adjunct to systemic chemotherapy in vitreoretinal lymphoma, particularly in cases of vitreous predominant disease manifestation.
