Abstract
Purpose To describe a case of choroidal melanoma treated with Rigvir® virotherapy in an adjuvant setting. Observations A female patient born in 1956 presented with a small choroidal melanoma in October 2007. 34 months after transpupillary thermotherapy the state of her eye worsened until tumor growth was visualized. Despite photodynamic therapy and transpupillary thermotherapy the tumor continued to grow locally. In October 2016 enucleation was performed. Since gene expression profile testing disclosed a tumor (class 2) with a high risk of metastasis formation in 5 years, the patient sought options to prevent progression of the disease. In December 2016 virotherapy with Rigvir® was started with 3 administrations for 3 consecutive days. Therapy was continued once per week until March 2017, when the administrations were changed to once per month. The patient is being monitored by an ophthalmologist. She is stable with the virotherapy ongoing and magnetic resonance cholangiopancreatography (7 May 2018) and abdominal ultrasound (23 March 2019) imaging excludes metastasis formation. The quality of life is high. Conclusions To the best of our knowledge, this is the first documented case of uveal melanoma treatment with virotherapy as an adjuvant therapy. Considering the few if any available treatments and the encouraging results of the present treatment, virotherapy should be evaluated more extensively as a potential treatment of uveal melanoma.

Abstract
PURPOSE To describe changes in blue-light fundus autofluorescence (FAF) and corresponding alterations in optical coherence tomography (OCT) within the irradiation field after ruthenium-106 brachytherapy (RBT) for choroidal melanoma. METHODS Consecutive patients with choroidal melanoma were included in a retrospective case series. Patients were treated with RBT at a single institution. As part of their routine examination patients underwent multimodal imaging including ultrasonography, fundus photography, OCT, and FAF imaging (excitation = 488 nm). FAF images were analysed for changes within the irradiation field. RESULTS 31 patients (mean age 65.7 years) were treated with RBT for unilateral choroidal melanoma. Mean tumour height before therapy was 2.7 mm (SD 1.0). Mean follow-up time was 23.3 months (SD 13.3). Main FAF characteristics attributable to RBT emerged as increased FAF with speckled decreased FAF (FAF mottling) within the irradiation field and a rim of increased FAF at its border. OCT scans demonstrated loss of the ellipsoid zone and the external limiting membrane, thinning of the neurosensory retina, and alterations of the retinal pigment epithelium like clumping, migration, and atrophy. CONCLUSIONS FAF changes in the irradiation field after RBT of choroidal melanomas follow a characteristic pattern that correlates with distinct OCT alterations. FAF and OCT imaging give additional information to monitor effects of RBT and, therefore, complement multimodal imaging techniques after plaque therapy.

Abstract
BACKGROUND Uveal melanoma is the most common primary intraocular malignancy in adults, but its incidence is low in Asian populations. Spontaneous corneal perforation and intratumoral calcification are rare presentations of choroidal melanoma (CM) , and reports regarding these presentations have been limited. Even after complete surgical treatment, the prognosis of CM patients is usually poor if distant metastasis is present. We here present a case of CM with unique presentations and early distant metastasis to the liver.
CASE SUMMARY A 63-year-old Asian woman presented to our hospital with complaint of pain and brownish discharge from her left eye for 3 d. Imaging studies revealed intratumoral calcification within the left eye with eyeball rupture. Enucleation of the left eye was performed and pathological examination confirmed the diagnosis of CM. Systemic surveillance revealed no metastatic diseases. However, the patient was lost to follow-up 3 mo after surgery. At 1.5 years after the operation, she presented to our emergency department with complaint of dull epigastric pain that radiated to the back for 1 d. Imaging studies revealed a large mass at the upper abdomen abutting the pancreatic neck and body as well as several nodular lesions in the liver. Fine needle biopsy was performed and findings confirmed liver and pancreatic metastases.
CONCLUSION This case highlights the importance of continued follow-up of patients with CM.

Abstract
Introduction Gamma knife radiosurgery (GKR) has shown promising results in the treatment of intraocular uveal melanoma (UM) in terms of local tumor control. However, GKR is not free from potentially sight-threatening side effects, including cataract, dry eye disease, vitreous hemorrhage, radiation retinopathy (RR), radiation maculopathy (RM), optic neuropathy, and neovascular glaucoma. The aim of this paper is to report our 20-year experience in UM management with GKR focusing on the rate of clinical treatment-induced complications. Methods Single-center, retrospective, observational study, including all patients with UM treated at the Ocular Oncology and Uveitis Service, in the Department of Ophthalmology of the San Raffaele Scientific Institute, Milan from September 1993 to September 2018. Clinical charts comprised complete ophthalmological examination with measurement of best-corrected visual acuity, slit-lamp biomicroscopy, intraocular pressure measurement, gonioscopy, and indirect ophthalmoscopy at each visit. B-scan ultrasound (Aviso S, 10 MHz probe; Paris, France), optical coherence tomography (Heidelberg Spectralis; Heidelberg Engineering, Heidelberg, Germany), retinography, and fundus fluorescein angiography (standard or ultra-widefield [UWF; California, Optos, Dunfermline, Scotland, UK]) were performed aiding in the diagnosis of complications. Results Overall, 194 patients (100 males, 51.6%) were reviewed. The median age at the time of the treatment was 65 years (range 27-89) and all participants were Caucasian. In 185 eyes (95.4%), the tumor was primarily located at the choroid. The median follow-up was 57.6 months; radiation-induced complications were found in 145 eyes (74.7%). Radiation-induced cataract and RR were the most frequent events, with a relative incidence of 41.2 and 34.5%, respectively, followed by neovascular glaucoma (27.3%), optic neuropathy (18.6%), RM (11.4%), vitreous hemorrhage (14.4%), phthisis bulbi (7.7%), hyphema (0.5%), and corneal melting (0.5%). The shorter onset of side effects involved the optic nerve (median 14.9 months) and the macula (median 13.7 months). Conclusion Despite modern and advanced strategies introduced to limit GKR side effects, cataract and RR still represent a serious limitation of this treatment. Incidence of RR was higher in our cohort compared to other reports, probably due to increased diagnosis rate permitted by UWF retinal imaging.

Abstract
Objective: To evaluate the imaging characteristics of choroidal melanoma before and after proton beam radiotherapy via Optos® ultra-wide-field scanning laser ophthalmoscopy. Methods: Retrospective, descriptive study of choroidal melanoma patients treated with proton beam radiotherapy. All patients underwent full clinical evaluation, including best-corrected visual acuity, ultrasound examination and ultra-wide-field scanning laser ophthalmoscopy imaging in the pseudo-colour (red and green channel) as well as auto-fluorescence mode. Tumours were classified and evaluated according to their location, size, presence of subretinal fluid, drusen, orange pigment and reflectance intensity in ultra-wide-field scanning laser ophthalmoscopy. Tumour sonographic (basal diameter, height) and ultra-wide-field scanning laser ophthalmoscopy imaging dimensions (maximal diameter) were documented. Results: A total of 39 eyes (38 patients) were followed for 24 months (range 6–48 months). Mean best-corrected visual acuity dropped from 20/40 to 20/63 after proton beam radiotherapy. There was no change in the imaging tumour characteristics during follow-up. Subretinal fluid changes were better detected in the autofluorescence compared to pseudo-colour mode. Mean tumour diameter did not significantly change in the ultra-wide-field scanning laser ophthalmoscopy although it did so in the ultrasound. No patient showed local tumour recurrence. Conclusion: The ultra-wide-field scanning laser ophthalmoscopy imaging characteristics of choroidal melanoma in the Optos® system do not significantly change after proton beam radiotherapy after a mean follow-up of 2 years.

Abstract
Purpose: The aim of the present study is to report the clinical and genetic characteristics of nevus of Ota with choroidal melanoma in Chinese patients. Patients and Methods: Patients with nevus of Ota with choroidal melanoma were identified by searching the computerized database and patient medical records of Beijing Shijitan Hospital and Shaanxi Yulin Tradition Chinese Medicine Hospital. The patients (2 men and 1 woman; mean age, 52 years; age range, 52‑57 years) were all treated by enucleation or local endoresection, and choroidal melanoma was confirmed by pathologic examination. Results: The patients (2 men and 1 woman; mean age, 52 years; age range, 52‑57 years) were all treated by enucleation or local endoresection, and choroidal melanoma was confirmed by pathologic examination. The study found that patients with nevus of Ota had higher risk for malignant melanoma. Furthermore, we found two suspicious gene mutations involving FAM111B and DSC2, that might contribute to the etiology of the disease. Conclusions: The results indicate that patients with nevus of Ota should undergo regular ophthalmological observation and be aware of the potential for malignancy.

Abstract
Neoplasms of the retinal pigment epithelium (RPE) are rare tumors that can simulate choroidal melanoma, but clinical and imaging characteristics often differentiate these lesions. We report a 70-year-old male with an abruptly elevated pigmented lesion that arose at the site of congenital hypertrophy of the RPE and demonstrated associated exudation, as well as feeding and draining vessels, suggestive of RPE adenoma. Optical coherence tomography showed retinal elevation with serous retinal detachment adjacent to the mass, and ultrasonography revealed an abruptly elevated, moderately echodense mass of 6.4-mm thickness. Fluorescein -angiography showed early tumor hypofluorescence, late -tumor hyperfluorescence with staining and leakage, and -retinal vessels buried under the mass, suggestive of a retinal tumor. The patient was monitored with the presumed diagnosis of RPE adenoma, but 3 months later, the growth was documented and fine-needle aspiration biopsy revealed choroidal melanoma. Management with I-125 plaque radiotherapy was performed leading to tumor regression and a thickness of 4.6 mm.

Abstract
Histologic and cytologic features of uveal melanomas have been well characterized; however, cytologic-histologic correlation has rarely been described in detail in the literature. A 50-year old female presented at our institution with an intraocular mass which was diagnosed as choroidal melanoma by aspiration cytology. The patient subsequently proceeded to enucleation, confirming the diagnosis. Cytology revealed epithelioid cells containing melanin pigment and only mild nuclear atypia. The enucleation specimen contained 90% epithelioid cells with similar cytomorphology and an additional 10% spindle cell component not observed in the aspiration cytology. In summary, we present a case of choroidal melanoma showing high concordance between cytologic and histologic morphologic features.

Abstract
PURPOSE Irradiation of choroidal melanoma is a safe and globe preserving procedure. Chronic inflammatory processes and ischemia are the main reasons for secondary enucleation in the long run. The aim of this study was to determine whether intraocular inflammation and especially inflammatory response after proton beam therapy (PBT) is related to primary tumor characteristics such as height, tumor volume, and initial flare values. METHODS Twenty-six patients treated for uveal melanoma using PBT were included. All patients were examined for signs of inflammation using laser flare photometry (LFP). Each examination included assessment of the melanoma and fellow eye (which acted as the control) and imaging of the melanoma. RESULTS Significant differences of flare values between melanoma eyes and control group were found both at baseline (median 17.65 ph/ms (min 4, max 37.10), 7.45 ph/ms (min 0.80, max 16.40), respectively) and during follow-up (median 21.45 ph/ms (min 4.5, max 70.90); 6.05 ph/ms (min 2.40, max 16.40), respectively) (p < 0.001, Wilcoxon test). Flare values in melanoma eyes increased significantly after PBT (p = 0.005, Wilcoxon test) and after a follow-up of 94 days (median, 7-420 days). Flare values of the control group did not change (p = 0.946, Wilcoxon test). The increase of flare values correlated significantly with maximum tumor height and volume (Spearman-Rho 0.633, p = 0.001 and 0.519, p = 0.007, respectively). CONCLUSION LFP has proven to show significantly higher flare values in melanoma eyes as compared with the control group and provides data on the course of the inflammatory response after treatment. It may ease treatment planning both at baseline and during follow-up.

Abstract
Purpose Histologic correlation of clinical patterns of recurrent choroidal melanoma following I-125 plaque brachytherapy was performed to identify pathologic mechanisms of recurrence. Methods We reviewed 7 cases of recurrent choroidal melanoma following I-125 plaque brachytherapy managed with enucleation. Clinical characteristics included tumor dimensions, radiation dose, time to local recurrence, and clinical pattern of recurrence. Histopathology (hematoxylin and eosin and periodic acid - Schiff) and immunohistochemistry (Ki-67, CD-163, HMB45, and SOX10) were performed. Results Mean follow-up time and time to local recurrence were 42 and 21 months after brachytherapy, respectively. Tumor recurrences were described clinically as marginal in 43%, diffuse in 29%, and extraocular extension (EOE) in 29%. Eighty-six percent were classified as mixed cell type and 14% were epithelioid type. Tumor zonation (histologic demarcation between zones of recurrent and nonrecurrent tumor cells by immunohistochemistry) was present in marginal and EOE cases (n = 6) and absent in the diffuse cases (n = 2). Ki-67 proliferative index was higher in marginal and EOE recurrences, while diffuse cases showed uniform -Ki-67 staining. CD-163 staining was found to be greater in nonrecurrent tumor. HMB45 correlated with SOX10 with a greater staining in recurrent tumor. Conclusion Our observations provide a correlation between histopathologic and clinical patterns of local recurrence of choroidal melanoma after brachytherapy.

Abstract
PURPOSE To describe the imaging features of choroidal nevus and melanoma using optical coherence tomography angiography, and evaluate the ability of this technique to establish the differential diagnosis based on the display of the tumor's intrinsic vasculature. METHODS Comparative analysis of optical coherence tomography angiography findings in consecutive patients diagnosed with choroidal nevus or choroidal melanoma following a complete ophthalmic evaluation, including best-corrected visual acuity and several imaging studies: color fundus photography, B-scan ultrasound, spectral-domain optical coherence tomography, and optical coherence tomography angiography. Optical coherence tomography angiography was used to investigate qualitative differences in the tumor vasculature. RESULTS Thirty-six eyes (18 cases of choroidal nevus and 18 cases of choroidal melanoma) from 36 consecutive patients were included in the study. Only cases located posterior to equator were included to enable performance of all tests. On optical coherence tomography angiography, choroidal nevus showed well-delimited margins (78%), hyperreflective choroid capillary vasculature (83%), fewer avascular areas (17%), and neovascular membrane in one case (6%). Choroidal melanoma showed imprecise margins (72%), hyporeflective choroidal capillary vasculature (72%), multiple avascular areas (78%), and choroidal vascular changes (e.g. thick vascular networks or vascular loops; 45%). CONCLUSION Optical coherence tomography angiography can provide useful information for assessing and differentiating between choroidal nevi and small melanomas. Significant differences between these conditions were found for the pattern of reflectivity, and presence/absence of avascular zones and vascular anomalies, which could be helpful for supporting the diagnosis.

Abstract
PURPOSE To describe didactically the local, regional and systemic spread of choroidal melanoma. PATIENTS AND METHODS Two patients who had undergone primary enucleation for the management of choroidal melanoma in 2018 at the University Hospital of Nice were included. Extrascleral extension and invasion of the vortex veins were evaluated, as well as synchronous and metachronous metastases, based on our database. RESULTS Patient 1 was diagnosed with large choroidal melanoma with partial scleral invasion and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3, and a gain of chromosome 8q. Systemic work-up was unremarkable. Patient 2 was diagnosed with a large choroidal melanoma with extrascleral extension and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3 and a gain of chromosome 8q. Systemic work-up revealed several liver metastases. A total of 1762 patients were included in our database. Eighty-five patients (4.8 %) and 46 patients (2.6 %) experienced vortex vein invasion and extrascleral extension respectively. Patients with vortex vein invasion were diagnosed with synchronous and metachronous liver metastases in 1.2 % and 18.8 % respectively. Patients with extrascleral extension had synchronous and metachronous liver metastases in 6.5 % and 30.4 % respectively. The mean follow-up was 49.4 months (1-180). CONCLUSION Extrascleral extension and vortex vein invasion illustrate the local, regional and systemic spread of choroidal melanoma. The latter are often associated with genetically aggressive tumours associated with high metastatic risk.

Abstract
Choroidal melanoma (CM) is the most commonly diagnosed primary intraocular malignancy in adults. Gamma knife radiosurgery (GKR) has demonstrated reliable results in the treatment of CM, but it is limited by the risk of radiation-induced ocular complications. To optimize the dose of radiation focused on the tumor, and limit side effects, the eye should be properly immobilized before treatment. A recently released ultra-widefield imaging instrument (Optomap California; Optos, Dunfermline, Scotland, UK) allows for an interactive three-dimensional (3D) virtual reconstruction of the globe, called 3D Wrap<sup>TM</sup>. The authors share their experience with this rapid, reliable, and relatively easy support in planning globe positioning before GKR treatment.

Abstract
Aims and Objectives Brachytherapy using removable ophthalmic plaques loaded with suitable small sealed radioactive seeds adjacent to the ocular's tumor has been widely used as an effective treatment. The aim of this study was to investigate the dose distribution in a modeled eyeball followed to loading of an ocular melanoma tumor with different concentrations of gold nanoparticles (GNPs) as dose enhancement agent by Monte Carlo (MC) calculations. Materials and Methods The MC code of MCNPX 2.6.0 was used to modeling of COMS standard eye plaque loaded with 24 125I sources (6711 model) located on the sclera of modeled eyeball with detailed structures and materials. A choroidal melanoma tumor was simulated and loaded with different concentrations of spherical gold GNPs (50 nm in diameter). Dose enhancement factors (DEFs) of ocular components were calculated. Results The dosimetric properties of 125I source (6711 model) and dose distribution of COMS standard eye plaque were calculated successfully as recommended by TG-43U1; AAPM. Loading of tumor with GNPs increased dose to the tumor and decreased dose to the normal tissues; the DEF was increased up to 2.280 and 2.030 for tumor apex, while it was decreased to 0.760 and 0.892 for macula and for gold-tumor mixture and nanolattice distributions, respectively. Conclusion Loading the choroidal tumor volume with GNPs improves the dose distribution by increasing dose to the tumor and decreasing dose to the health components in ocular brachytherapy with 125I seeds 20-mm COMS plaque.

Abstract
Background Early confirmation of the effect of brachytherapy for choroidal melanoma showing that tumour coverage is valuable. The irradiated retinal pigment epithelium (RPE) commonly develops atrophy. This study compares the fundus autofluorescence (AF) changes to the development of RPE atrophy following brachytherapy. Methods Retrospective study of 19 patients treated with <sup>106</sup>Ru and 2 with <sup>125</sup>I plaques with either a 3- or 6-month follow-up period. Ultra-widefield (UW) composite colour and AF images were obtained with Optomap 200Tx and interpreted as complete, partial, or no RPE changes and complete or partial hyperautofluorescence, hypoautofluorescence, or isoautofluorescence. Results At the 3-month follow-up, 9 of 13 patients (69%) (95% confidence interval [CI], 0.389-0.896) treated with <sup>106</sup>Ru plaques developed complete homogenous hyperautofluorescence surrounding the tumour, but only 1 of 13 (8%) (95% CI, 0.004-0.379) developed complete RPE atrophy at the same time point. Six patients in the <sup>106</sup>Ru plaque group had their first follow-up with UW imaging at 6 months. Four of them developed homogenous hyperautofluorescence and none developed complete RPE atrophy around the tumour. The 2 patients treated with <sup>125</sup>I did not demonstrate any clear RPE or AF changes. Conclusion The effect of <sup>106</sup>Ru plaque treatment on fundus UW imaging is detected as homogenous and well-demarcated hyperautofluorescence before visible RPE atrophy.

Abstract
Background/Aims Patients with choroidal melanoma can develop psychological morbidity because of visual disability, pain, facial deformity, and fears of metastatic disease. The aim of this study was to report on the prevalence of symptoms, moods, and well-being after radiotherapy or enucleation for choroidal melanoma and how these outcomes changed over time. Methods Participants were mailed questionnaires approximately 6 months following treatment, then annually on every anniversary of their treatment. Results Soon after enucleation, patients experienced visual difficulties because of loss of stereopsis and visual field and were concerned about their appearance and about metastatic disease. After radiotherapy, patients were more concerned about local tumor recurrence and more troubled by diplopia and headache. Over time, visual difficulties diminished after enucleation but increased in patients who had received radiotherapy, with concerns about metastasis, loss of health, and tumor recurrence diminishing in both groups. Anxiety tended to diminish whereas depression increased, especially after enucleation. Emotional well-being improved after both kinds of treatment, whereas functional and physical well-being diminished after enucleation but improved after radiotherapy. Self-reported quality of life diminished equally with both kinds of treatment. Conclusion The findings of this study should help physicians understand what patients tend to feel after treatment for choroidal melanoma.

Abstract
BACKGROUND Ophthalmologists and retina specialists may consider choroidal detachment if patients with rhegmatogenous retinal detachment present with choroidal elevation. That misdiagnosis may lead to inappropriate treatments, development of tumor cell dissemination, and eventual promotion of patient death. We report a case of a patient with rhegmatogenous retinal detachment associated with choroidal melanoma simulating choroidal detachment according to fundus findings. CASE PRESENTATION A 78-year-old Japanese woman with blurred vision in her right eye was referred to our hospital because of rhegmatogenous retinal detachment with complicated atypical choroidal detachment. Her intraocular pressure was normal with clear anterior chamber. Retinal detachment involving the inferior and nasal retina was observed, and a retinal hole was noted in the same quadrant. A small yellowish choroidal elevation was located in the inferonasal site. Gadolinium-enhanced magnetic resonance imaging revealed enhancement corresponding to the elevation, leading to the identification of a choroidal tumor. Enucleation of the patient's right eye was eventually performed. The enucleated eye histologically demonstrated malignant melanoma. CONCLUSIONS If hypotony or an inflammatory sign is absent, ophthalmologists should pay attention to the differential diagnosis of choroidal elevations observed in such patients.

Abstract
Background/Aims To evaluate a treatment regimen for radiation papillopathy. Methods This is a prospective noncomparative interventional case series of patients who developed radiation papillopathy after plaque brachytherapy for uveal melanoma. Treatment consisted of intravitreal bevacizumab (IVB) (1.25 mg in 0.05 mL) at the time of diagnosis, and 1 week later, intravitreal triamcinolone (IVK) (2.00 mg in 0.05 mL). One month later, patients again received both IVB and IVK. Patients were then switched to monotherapy with monthly IVB until the papillopathy resolved. Results Eleven patients developed radiation papillopathy, with 9 receiving treatment. On multivariate analysis, total radiation dose to the optic nerve was the only significant predictor of papillopathy (p = 0.005). Four of nine patients presented with a significant decline in visual acuity (VA) at the time of diagnosis of papillopathy. In all 4, significant improvement was documented following treatment. Five patients did not present with a decrease in VA, and in this group, 80% remained stable with treatment. Conclusions In this series, patients who had a precipitous drop in VA at the time of diagnosis of radiation papillopathy returned to baseline VA following this treatment algorithm. This protocol was effective at maintaining stability of VA in 80% of those who developed papillopathy but did not present with an acute drop in VA.

Abstract
Multifocal uveal melanomas are extremely rare. In this case report, we describe a patient with 2 independent uveal melanomas in the same eye. A 52-year-old woman presented with a large choroidal melanoma and a smaller ciliary body mass, clinically thought to be a nevus, in her left eye. Enucleated specimen showed 2 primary lesions that were anatomically separate. Lesion 1 was a melanoma and lesion 2 was a melanoma arising centrally from a nevus. Both lesions harbored GNAQ mutations. This patient had no family history of uveal melanomas or signs of ocular melanocytosis and was negative for the BAP1 mutation. This case demonstrates how multifocal uveal melanomas can arise in patients who lack genetic predisposition for the disease. Furthermore, this case is one of the few that have shown, histopathologically, a small focus of malignant cells developing from a benign population within a nevus, which highlights the importance of closely monitoring nevi for signs of malignancy.

Abstract
Background To describe the superiority of ocular ultrasound in the diagnostic management of extrascleral extension in choroidal melanoma. Case presentation We present a case of a 94-year-old male with choroidal melanoma of the right eye imaged with MRI and ocular ultrasound to aid in the detection of extrascleral extension. Conclusions With advancement in technology and new imaging modalities emerging, it can become difficult to determine the best diagnostic approach for patients. We believe that ocular ultrasound remains the superior imaging modality in detection of extrascleral extension in choroidal melanoma.

Abstract
BACKGROUND/AIMS Plaque brachytherapy is currently the most common treatment for uveal melanoma and has many known potential complications. Here we present 3 cases of early conjunctival and scleral necrosis following iodine-125 plaque. METHODS This study was conducted as a retrospective case series. RESULTS We identified 3 cases of early conjunctival and scleral necrosis following iodine-125 plaque. All patients were managed conservatively with resolution of the necrosis. CONCLUSIONS While delayed corneoscleral necrosis following plaque brachytherapy has been previously reported, occurring many months to years after treatment, the 3 cases in this series presented within 2-6 weeks in the postoperative period. While we were unable to identify a specific etiology, we believe this represents a distinct clinical entity of post-brachytherapy cornea-scleral necrosis that is important to recognize. Possible causes include acute radiation toxicity, mechanical trauma, and/or conjunctival microinfection.

Abstract
We describe a case of choroidal melanoma initially presenting with orbital cellulitis, fulminant conjunctival swelling, and secondary angle closure. Despite treatment with intravenous antibiotics, the patient's condition did not improve. With further investigations including ultrasound scan and magnetic resonance imaging, a high-density lesion was found within the globe. Characteristic imaging findings suggested a malignant origin and the lesion was found to be a melanoma on histopathological analysis.

Abstract
Purpose: To report mortality of patients who were eligible for enrollment in the Collaborative Ocular Melanoma Study (COMS) clinical trials of medium-sized choroidal melanoma or large-sized choroidal melanoma but chose to defer treatment or receive no melanoma treatment. Design: Prospective nonrandomized multicenter cohort study as an adjunct to COMS randomized clinical trials. Methods: Patient follow-up procedures included examinations, correspondence, telephone contacts, and National Death Index searches. Primary outcome was patient death measured by all-cause mortality. Secondary outcomes were melanoma treatment and melanoma metastasis. Results: Of 77 patients eligible for COMS clinical trials who chose to defer or receive no melanoma treatment, 61 were appropriate candidates and 45 (74%) enrolled in the natural history study (NHS). In all, 42 patients (42 eyes) had medium melanoma, and the median follow-up was 5.3 years (range, 4–10.7 years). In all, 22 patients (52%) had subsequent melanoma treatment, and 20 (48%) had no melanoma treatment. For the 42 patients, Kaplan–Meier estimate of 5-year mortality was approximately 30% [95% confidence interval (CI), 18%–47%]. For COMS medium melanoma trial, 5-year mortality was 18% (95% CI, 16%–20%), not statistically significantly different from the NHS patients. After adjusting for differences in age and longest basal diameter, the 5-year risk of death for NHS patients versus COMS trial patients was 1.54 (95% CI, 0.93–2.56). Three patients had large melanoma. Melanoma metastasis was confirmed or suspected in 8 (42%) of 19 deaths. Conclusion: Greater mortality and higher risk of death for NHS patients are probative but not conclusive evidence of a beneficial, life-extending effect of medium melanoma treatment.

Abstract
PURPOSE: The purpose of this study is to report on treatment outcomes for medium-sized choroidal melanoma treated with Ruthenium-106 (Ru-106) plaque brachytherapy. METHODS: A retrospective case series of 28 patients received Ru-106 brachytherapy treatment for choroidal melanoma. The prescribed tumor dose was 85 Gy to a depth of 5 mm. RESULTS: Median follow-up was 31.2 months. At 12 and 24-month postirradiation, the best corrected visual acuity ≥20/70 (LogMar ≥−0.54) was 53.8% and 64.2%, respectively. Median time to tumor regression was estimated to be 10 months (95% CI = 9–18 months), with 100% of response rate by 32 months. Radiation-induced side effects were limited, and there were no postradiation enucleations. CONCLUSIONS: The majority of patients maintained good visual acuity, with no enucleations and minimal side effects. In this cohort, the Ru-106 plaque brachytherapy proved to be an efficacious and safe treatment option for patients with medium-sized choroidal melanomas with a maximal tumor height of 5 mm.

Abstract
BACKGROUND/AIMS Our study aims to better characterize the clinical and histopathologic features of eyes with extrascleral uveal melanoma associated with scleral melt following brachytherapy. METHODS A retrospective review was performed on patients who had undergone 125I (iodine-125) brachytherapy for uveal melanoma at our institution between 1992 and 2015. Patients with postradiation scleral necrosis who required enucleation were identified, and an analysis including a review of histopathology results was performed on those cases. RESULTS A total of 301 patients underwent plaque brachytherapy for uveal melanoma, of whom 31 required eventual enucleation. The histologic analysis showed extraocular extension through full-thickness scleral discontinuities in 6 cases. All but 1 (5 of 6) of these eyes exhibited either mitotic figures or Ki-67 positivity. Mitotic figures were noted in 4 specimens, including 3 eyes exhibiting mitoses within or adjacent to the extrascleral portion of the tumor. Two eyes exhibiting mitoses, as well as the case with Ki-67 positivity, also had clinical evidence of tumor regrowth. CONCLUSION We found evidence of mitotic activity at the area of scleral discontinuity in some eyes with and in some without clinical evidence of tumor regrowth. Protruding pigmented material in areas of scleral necrosis after plaque brachytherapy may represent actively proliferating tumors even without internal evidence of tumor regrowth.
