From 1975 to 1984, thirteen patients were submitted to radiotherapy for choroid metastases of mammary carcinoma. Bilateral manifestation was found in three cases, thus sixteen eyes have been treated. All irradiations were performed with high voltage equipment. The posterior section of the eye was irradiated with 25 to 50 Gy over 2.5 to 5 weeks. Complete regression was achieved in nine out of sixteen cases, five patients showed an improvement of at least 50%, no considerable effect was found in two cases. The survival is 4 to 48 months (median survival 20 months) from the beginning of radiotherapy. Radiotherapy is a quick, efficient, and sparing treatment in choroid metastases. If applied in due time, it can prevent a visual disorder or amaurosis, thus improving the patients' quality of life.

Purpose: To present the case of a young patient with BRAF V600E-mutant cutaneous melanoma who developed bilateral choroidal metastases complicated by neovascular glaucoma (NVG) in both eyes following the interruption of nivolumab therapy.
Methods: A 28-year-old female with primary cutaneous melanoma of the left hand underwent surgical resection and adjuvant nivolumab. Immunotherapy was discontinued due to immune-related acute interstitial nephritis.

An 8-year-old girl with refractory high-risk neuroblastoma underwent 68Ga-DOTATATE PET/CT to evaluate the feasibility of potential 177Lu-DOTATATE therapy. The scan showed multiple foci of abnormal 68Ga-DOTATATE accumulation in the bone region, indicating the presence of bone metastases. Unexpectedly, an abnormal tracer uptake was noted in the left lateral ventricle area.

The aim of the study was todescribe the clinical features, optical coherence tomography (OCT) and fundus autofluorescence (FAF) imaging in patients with choroidal and retinal tumors. Ninety eyes of 89 patients with treatment-naive macular, midperipheral, and juxtapapillary choroidal and retinal tumors were retrospectively included in the study. All patients underwent a complete ophthalmic examination, B-mode ultrasonography, OCT, and FAF imaging.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.

Introduction: Choroidal metastases from systemic malignancies are the most common intraocular malignancies in adults. External beam radiation (EBR) has historically been first-line therapy for metastatic tumors to the choroid. However, good responses have been described with newer targeted biologics.
