Purpose: To evaluate, in eyes with radiation maculopathy, the effect of 2-month-interval anti–vascular endothelial growth factor therapy on best-corrected visual acuity and foveal avascular zone (FAZ) enlargement using optical coherence tomography angiography. Methods: Consecutive treatment-naive patients with radiation maculopathy after proton beam irradiation for choroidal melanoma were retrospectively included. Clinical and optical coherence tomography angiography data at baseline and the 6-month visit were recorded. Two independent observers measured FAZ area manually on 3 × 3-mm optical coherence tomography angiography images of the superficial capillary plexus and deep capillary plexus. Patients were encouraged to follow strictly a 2-month-interval intravitreal anti–vascular endothelial growth factor treatment by either bevacizumab or ranibizumab. Findings were analyzed based on the adherence to the treatment scheme. Results: According to the adherence to the bimonthly anti–vascular endothelial growth factor treatment protocol, patients were categorized into 3 groups: treatment protocol (n = 19, strict adherence), variable intervals (n = 11, intervals other than 2 months), and no treatment (n = 11). The estimated radiation dose to the foveola in each group was 49 ± 16, 46 ± 17, and 46 ± 18 cobalt gray equivalent, respectively (P = 0.85). For the entire cohort, best-corrected visual acuity loss (P

CONCLUSION: In case of PEHCR, multimodal imaging is useful to avoid misdiagnosis, to characterise PEHCR lesions and to guide treatment strategies. Regression of PEHCR lesions was observed in two-thirds of the patients. Vitrectomy improved visual acuity. More than a third of patients underwent anti-VEGF IVTI. Further studies are needed to assess IVTI's efficacy. PMID: 31645320 [PubMed - as supplied by publisher]

le Parrozzani Intraocular tumor diagnosis is based on clinical findings supported by additional imaging tools, such as ultrasound, optical coherence tomography and angiographic techniques, usually without the need for invasive procedures or tissue sampling. Despite improvements in the local treatment of uveal melanoma (UM), the prevention and treatment of the metastatic disease remain unsolved, and nearly 50% of patients develop liver metastasis. The current model suggests that tumor cells have already spread by the time of diagnosis, remaining dormant until there are favorable conditions. Tumor sampling procedures at ...

Conclusion: Swept-source optical coherence tomography angiography represents a valid imaging technique to evaluate patients affected by choroidal melanomas. In our series, SS-OCT-A disclosed the intrinsic microvasculature of the tumor in all cases despite their size, location, and history of previous treatments.

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.

Conclusions: Despite advanced hepatic metastatic spread, favorable survival can be achieved after RE in patients with uveal melanoma. In the view of other evolving treatment options (immunotherapy, chemosaturation) prognostic factors as well as treatment sequence and combination are to be evaluated.

We report such a case. A 63-year-old woman with metastatic cutaneous malignant melanoma experienced visual loss in both eyes 10 days after her second nivolumab injection. Her decimal best-corrected visual acuity (BCVA) was 0.7 in the right eye and 0.4 in the left eye. Examination revealed bilateral granulomatous keratic precipitates and posterior synechiae in the left eye. Optical coherence tomography showed multiple sites of serous retinal detachment (SRD) in the left eye and wavy retinal pigment epithelium in both eyes. Fluorescein angiography revealed multiple pinpoint-sized areas of leakage in both eyes and active leak...

Purpose: Radiation retinopathy remains incompletely characterized and may cause severe vision loss. Ultra–wide-field fluorescein angiography provides a pan-fundus view of vascular alterations caused by radiation treatment and may predict visual and ocular outcomes. We have developed a grading scheme to describe pan-fundus severity and to predict the progression of radiation retinopathy in patients treated for uveal melanoma with iodine-125 brachytherapy. Methods: A retrospective review of patients treated with standard iodine-125 brachytherapy for uveal melanoma at the Ophthalmic Oncology Center at the Universit...

Authors: Nürnberg D, Seibel I, Riechardt AI, Brockmann C, Zeitz O, Heufelder J, Joussen AM Abstract Imaging of intraocular tumors is multimodal, multi-purpose, and in continuous development. Therefore, imaging is indispensable for the detection, diagnosis, therapy and monitoring of intraocular tumours. A broad spectrum of imaging procedures is available for diagnostic testing and follow-up. This includes colour image acquisition, infrared imaging, autofluorescence imaging, fluorescence and indocyanine green angiography, optical coherence tomography (OCT) and sonography (US). In this article, the various invest...
