Abstract
The migration of silicone oil into the suprachoroidal region is a rare complication of vitrectomy. A 70-year-old man was admitted to our ocular oncology unit with a choroidal elevation in the nasal area, as well as signs of pars plana vitrectomy surgery performed about 5 years ago for retinal detachment. The patient underwent ocular ultrasound, visual field test, fluorangiography, and magnetic resonance imaging, which led to the diagnosis of silicone oil migration in the suprachoroidal space. Silicone oil may move into the suprachoroidal area, mimicking choroidal neoformation. It is important to have a comprehensive diagnosis and then set up the appropriate treatment.

Abstract
Purpose To describe an atypical case of a choroidal melanoma presenting with eyelid edema, chemosis, pain and diplopia and demonstrating significant extraocular extension on ultrasonography and neuroimaging. Observations A 69-year-old woman presented with a headache, eyelid edema, chemosis and pain in the right eye. Upon subsequent onset of diplopia, MRI of the orbits was performed and demonstrated a predominantly extraocular, intraconal mass with a small intraocular component. She was started on corticosteroids and referred to the ocular oncology service for evaluation. On fundus examination, she was noted to have a pigmented choroidal lesion consistent with melanoma, and ultrasound showed a large area of extraocular extension. Enucleation, enucleation with subsequent radiation and exenteration were discussed, and the patient requested an opinion from radiation oncology. A repeat MRI obtained by radiation oncology demonstrated a decrease in the extraocular component after corticosteroid treatment. The improvement was interpreted as suggestive of lymphoma by the radiation oncologist who recommended external beam radiation (EBRT). Fine needle aspiration biopsy was insufficient for cytopathologic diagnosis, and the patient elected to proceed with EBRT in the absence of a definitive diagnosis. Next generation sequencing revealed GNA11 and SF3B1 mutations, which supported the diagnosis of uveal melanoma and led to enucleation. Conclusion and Importance Choroidal melanoma may present with pain and orbital inflammation secondary to tumor necrosis, which may delay diagnosis and decrease the diagnostic yield of fine-needle aspiration biopsy. Next generation sequencing may aid the diagnosis of choroidal melanoma when there is clinical uncertainty and cytopathology is unavailable.

Abstract
Conversely to most tumour types, magnetic resonance imaging (MRI) was rarely used for eye tumours. As recent technical advances have increased ocular MRI's diagnostic value, various clinical applications have been proposed. This systematic review provides an overview of the current status of MRI in the clinical care of uveal melanoma (UM) patients, the most common eye tumour in adults. In total, 158 articles were included. Two- and three-dimensional anatomical scans and functional scans, which assess the tumour micro-biology, can be obtained in routine clinical setting. The radiological characteristics of the most common intra-ocular masses have been described extensively, enabling MRI to contribute to diagnoses. Additionally, MRI's ability to non-invasively probe the tissue's biological properties enables early detection of therapy response and potentially differentiates between high- and low-risk UM. MRI-based tumour dimensions are generally in agreement with conventional ultrasound (median absolute difference 0.5 mm), but MRI is considered more accurate in a subgroup of anteriorly located tumours. Although multiple studies propose that MRI's 3D tumour visualisation can improve therapy planning, an evaluation of its clinical benefit is lacking. In conclusion, MRI is a complementary imaging modality for UM of which the clinical benefit has been shown by multiple studies.

Stereotactic irradiation on linear accelerator - ultrasound versus MRI in choroidal melanoma volume calculation. BMC Ophthalmol 2022; 22:333. [PMID: 35931996 PMCID: PMC9356474 DOI: 10.1186/s12886-022-02558-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 07/28/2022] [Indexed: 11/10/2022] Open
Abstract
Background Stereotactic irradiation is one of the treatment modalities for intraocular uveal melanoma. The study’s purpose was to describe the background of stereotactic one-day session radiosurgery, how the comparison in the difference between the tumor volume measured values from the magnetic resonance imaging (MRI) method and the ultrasound method was related to it, and which method was more precise to be used for tumor regression after irradiation. Methods The group of 147 patients with choroidal melanoma was treated by stereotactic irradiation on the linear accelerator with a single dose of 35.0 Gy. During the standard treatment process the uveal melanoma volumes, needed for dose calculation, were obtained using MRI from the individual stereotactic planning scheme and by ultrasound from the ultrasound device. All volumes were statistically compared using the paired t-test, and for the visualization purpose, the Bland-Altman plot was used. Results In the group of patients, it was 70 (47.6%) males and 77 (52.4%) females. The tumor volume median was from MRI equal to 0.44 cm3 and from ultrasound equal to 0.53 cm3. The difference between the ultrasound and the MRI volume measured values was statistically significant. However, the Bland-Altman plot clearly documents that the two methods are in agreement and can be used interchangeably. In most of the cases, the measured values of the ultrasound-calculated volume achieved slightly higher measured values. Conclusions The calculation of the intraocular uveal tumor volume is a crucial part of the stereotactic irradiation treatment. The ultrasound volume measured values were in most of the cases higher than the measured values from the MRI. Although the methods are comparable and can be used interchangeably, we are recommending using the more precise MRI method not only during the treatment but also on later regular medical checks of tumor regression or progression.

Abstract
Simple Summary Uveal melanoma is the most prevalent intraocular tumor in adults, derived from melanocytes; the liver is the most common site of its metastases. Due to troublesome tumor localization, different imaging techniques are utilized in diagnostics, i.e., fundus imaging (FI), ultrasonography (US), optical coherence tomography (OCT), single-photon emission computed tomography (SPECT), positron emission tomography/computed tomography (PET/CT), magnetic resonance imaging (MRI), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), or fundus autofluorescence (FAF). Specialists eagerly use these techniques, but sometimes the precision and quality of the obtained images are imperfect, raising diagnostic doubts and prompting the search for new ones. In addition to analyzing the currently utilized methods, this review also introduces experimental techniques that may be adapted to clinical practice in the future. Moreover, we raise the topic and present a perspective for personalized medicine in uveal melanoma treatment. Abstract Uveal melanoma is the most common primary intraocular malignancy in adults, characterized by an insidious onset and poor prognosis strongly associated with tumor size and the presence of distant metastases, most commonly in the liver. Contrary to most tumor identification, a biopsy followed by a pathological exam is used only in certain cases. Therefore, an early and noninvasive diagnosis is essential to enhance patients’ chances for early treatment. We reviewed imaging modalities currently used in the diagnostics of uveal melanoma, including fundus imaging, ultrasonography (US), optical coherence tomography (OCT), single-photon emission computed tomography (SPECT), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), fundus autofluorescence (FAF), as well as positron emission tomography/computed tomography (PET/CT) or magnetic resonance imaging (MRI). The principle of imaging techniques is briefly explained, along with their role in the diagnostic process and a summary of their advantages and limitations. Further, the experimental data and the advancements in imaging modalities are explained. We describe UM imaging innovations, show their current usage and development, and explain the possibilities of utilizing such modalities to diagnose uveal melanoma in the future.

ARCHIVOS DE LA SOCIEDAD ESPANOLA DE OFTALMOLOGIA 2022; 97:70-76. [PMID: 35152951 DOI: 10.1016/j.oftale.2021.02.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 02/03/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND AND PURPOSE Uveal melanoma is the most common primary malignant intraocular tumour in the adult population, with a survival rate of 50% despite advances in treatment and knowledge of this disease. The presence of extraocular extension (EE) worsens the prognosis of these patients, so its proper identification can ensure its management and early intervention. Ophthalmological ultrasound is the technique of choice for the diagnosis and follow-up of these patients, both of the anterior EE using ultrasonic biomicroscopy (UBM), and the posterior EE using A and B ultrasound. The aim of this study is to describe the ultrasound characteristics of the BMU and the A and B ultrasound. MATERIAL AND METHODS A descriptive and retrospective study is carried out on patients diagnosed with uveal melanoma (UM) and EE from 2003 to 2019. The ultrasound characteristics of the local disease and the follow-up after treatment were recorded completely and at each visit. In the case of anterior EE, photographs of the anterior segment and UBM were taken, while those involving the posterior segment were explored under A and B mode ultrasound. All enucleated eyes were sent for anatomopathological study. RESULTS Ten patients with an average age of 72.3 years were included. The largest proportion of them were medium-sized tumours, followed by large and small ones. The most frequent morphology of the primary tumour was cupuliform. All the EE presented lower internal reflectivity compared to the primary tumour. No trans-scleral connection bridges were found between the primary tumour and the EE in the ultrasound studies. 50% of patients underwent primary enucleation at the time of diagnosis of intraocular MU due to the presence of the EE, and the remaining 50% presented the EE after initial treatment of the primary tumour with I125 brachytherapy. Sixty percent of the patients presented with posterior EE, and were therefore diagnosed with ultrasound A and B. The most frequent histopathological pattern with 87.5% of patients was the epithelioid pattern. DISCUSSION Ultrasound scanning in patients with MU is mandatory for diagnosis and follow-up of EE. BMU and A and B ultrasound are the test of choice for anterior and posterior EE, respectively. EE have particular ultrasound characteristics such as low internal reflectivity, regularity of their contour and their location usually adjacent to the base of the primary intraocular tumor.

Abstract
A 34-year-old female greater sulfur-crested cockatoo (Cacatua galerita galerita) was referred for suspected left globe rupture. Ophthalmic examination revealed effacement of the anterior chamber and cornea by a large mass. The left eye was enucleated due to suspicion of globe rupture, secondary to a neoplastic process or chronic trauma. Histopathological examination revealed complete effacement of the internal ocular structures by a neoplasm morphologically consistent with an iridociliary adenoma. The diagnosis was confirmed by Periodic acid-Schiff histochemistry and immunohistochemistry for S100, Melan-A/PNL2, and vimentin antigens. The cockatoo recovered well from surgery, with appropriate healing of the enucleation site, and no evidence of recurrence at 1-year follow-up. Key clinical message: To the authors' knowledge, this is the first report of iridociliary adenoma in a greater sulfur-crested cockatoo, and the third report of such a neoplasm in a psittacine species with a description of the use of immunohistochemistry to confirm a diagnosis of a rare tumor in a bird species.

Abstract
Choroidal melanomas are the most common ocular malignant tumors worldwide. The onset of such tumors is insidious, such that affected patients often have no pain or obvious discomfort during early stages. Notably, enucleation is required for patients with a severe choroidal melanoma, which can seriously impact their quality of life. Moreover, choroidal melanomas metastasize early, often to the liver; this eventually causes affected patients to die of liver failure. Therefore, early diagnosis of choroidal melanomas is extremely important. Unfortunately, an early choroidal melanoma is easily confused with a choroidal nevus, which is the most common benign tumor of the eye and does not often require surgical treatment. This review discusses recent advances in the use of multimodal and molecular imaging to identify choroidal melanomas and choroidal nevi, detect early metastasis, and diagnose patients with choroidal melanomas.

Abstract
BACKGROUND Melanoma is a highly malignant skin tumour, and is one of the most rapidly growing malignant tumors in recent years. According to statistics, the morbidity of cancer increases with age, accounting for 1.6% of new cancer cases and 0.6% of deaths worldwide. Melanoma has a serious impact on society and families, thus it is of great significance to find biological markers related to the diagnosis and treatment of melanoma.
AIM To explore the expression and predictive value of mir-489 and mir-21 in melanoma metastasis.
METHODS A total of 60 patients with malignant melanoma treated at our hospital from June 2017 to December 2018 were selected as a research group, while 40 healthy subjects were selected as a control group. qRT-PCR technique was used to detect miR-489 and miR-21 in serum of the two groups. ROC curve was drawn to evaluate the predictive value and diagnostic efficiency. Spearman test was used for correlation analysis. Logistic single- and multiple-factor analyses were performed to identify the risk factors related to melanoma metastasis.
RESULTS The expression of miR-489 in the research group was significantly lower than that in the control group (P < 0.001). However, the expression of miR-21 in the research group was significantly higher than that in the control group (P < 0.001). The expression of miR-489 and miR-21 was related to TNM stage and metastasis (P < 0.001). In the diagnosis of melanoma patients, the sensitivity, specificity, and AUC of miR-489 alone were 75.56%, 80.00%, and 0.852, respectively. The sensitivity, specificity, and AUC of miR-21 alone were 77.78%, 82.22%, and 0.844, respectively. MiR-489 was negatively correlated with TNM stage of melanoma (r = -0.612, P < 0.001), while miR-21 was positively correlated with TNM stage (r = 0.609, P < 0.001). Logistic single- and multiple-factor regression analyses showed that TNM stage, miR-489, and mir-21 were independent risk factors for malignant melanoma metastasis.
CONCLUSION MiR-489 and miR-21 may participate in the process of melanoma occurrence, development, and metastasis, and can be used as potential serum biomarkers for melanoma metastasis diagnosis and disease assessment.

Abstract
BACKGROUND In the recently published article entitled "Ocular ultrasound versus MRI in the detection of extrascleral extension in a patient with choroidal melanoma" Jacobsen et al. describe a case in which a hyper-intense extra-ocular lesion on MRI was erroneously diagnosed as an extrascleral extension of the tumor. Based upon this the authors conclude "the superiority of ocular ultrasound in the diagnostic management of extra scleral extension in choroidal melanoma". In our view, there are numerous flaws in the investigation that cast doubt on this message. MAIN: First of all, this is quite a bold statement when only one patient has been evaluated. Secondly, the manuscript only presents a post-contrast T1-weighted image, whereas multiple MRI-sequences need to be included to determine if a hyperintense region is an extrascleral invasion. Moreover, no modern MRI-techniques such Dynamic Contrast Enhanced (DCE) or Diffusion Weighted Imaging (DWI) have been included in the evaluation of this patient, making it hard to use this single case to compare the efficacy of MRI and Ultrasound. The presented data do, however, give clear clues that the hyperintense lesion is likely to be inflammatory. CONCLUSION Although the study falls short in providing a comprehensive comparison between current MRI techniques and ultrasound, it does show that the evaluation of ocular MR-images should be made in a multi-disciplinary setting involving both ophthalmologist and radiologists, since the field of ocular MRI is continuously progressing.
