SD-OCT patterns of the different stages of choroidal metastases

A Case of Binocular Metastatic Choroidal Tumor Originating from Pulmonary Adenocarcinoma Successfully Treated with Molecular Target Therapy

The occurrence of ocular metastasis from lung cancer is uncommon. In our current case, we report on a 64-year-old male patient found to have metastatic lesions in both choroids after being diagnosed with lung adenocarcinoma. As the patient was found to have a mutation in the epidermal growth factor receptor (EGFR), he was treated with the EGFR tyrosine kinase inhibitor (EGFR TKI), afatinib. However, the treatment response suggested the presence of a progressive disease. Thus, due to cancerous meningitis, the patient's treatment was changed from afatinib to erlotinib, in addition to adding bevacizumab. Although the general condition of the patient did not change, improvement was noted for the choroidal metastasis. Moreover, the drug change also resulted in an improvement of the visual power of both eyes. Therefore, the results for this patient suggest that systemic administration of erlotinib and bevacizumab may be an effective treatment that leads to morphological and functional improvement in choroidal metastasis cases.

Choroidal sarcoid granuloma: a case report and review of the literature

Background

Choroidal sarcoid granulomas are often diagnosed in patients without a prior history of sarcoidosis. They are often mistaken for choroidal metastasis, choroidal nevi, amelanotic choroidal melanomas, and uveal lymphomas; however, are easily treatable when accurately identified.

Observations

We searched PubMed, Medline, and Scopus for English-Language case reports published before September 2021. Additionally, we presented a case of a 45-year-old woman with a right-sided amelanotic choroidal mass whose diagnosis was delayed by a COVID-19 infection. Of the 26 cases reported in the literature, 46% were female, 38% were African American, and 19% had bilateral involvement. There was a mean age of 42.15 years and a mean follow-up period of 27 months. The most common complaint was of a progressive, painless blurring of vision, and only five patients had been previously diagnosed with sarcoidosis. The choroidal granulomas were typically described as yellow lesions, single or multiple, found temporal to or at the macula. Most patients were administered steroids, with 69% receiving them systemically, 5% topically, and 8% locally with a triamcinolone injection. All patients reported symptomatic improvement at their final follow-up with resolution of the mass in 65% of patients and improved visual acuity in 76%.

Conclusion

Primary testing including fundoscopy, fluorescein angiography, fundus autofluorescence, A/B-scan, and OCT are useful for diagnosis, differentiation from other choroidal lesions, and monitoring treatment response. Steroids are a mainstay of treatment for sarcoidosis and are effective at treating choroidal granulomas. Therefore, early recognition and diagnosis of choroidal granulomas is imperative as treatment can be curative and sight-sparing.

Choroidal mass secondary to mucinous cystadenocarcinoma of ovary in a young woman: a life-threatening metastasis

Objective: To report a case of choroidal mass secondary to mucinous cystadenocarcinoma of ovary in a young woman. Method: A case report. Result: A 21-year-old woman presented with insidious painless, progressive, central scotoma of the right eye for 5 weeks. She was disease free for 9 years after she underwent right salpingo-oophorectomy for her mucinous cystadenocarcinoma of right ovary. She completed 6 cycles of chemotherapy regimen. On presentation, her visual acuity was counting finger in the right eye and 6/ 6 in the left eye. Both anterior segments were unremarkable. Fundus examination of the right eye showed multiple choroidal masses with the largest in the temporal to fovea. Generally, she was well. Her tumor markers were raised. Urgent Computed Tomography (CT) Scan of thorax, abdomen and pelvis showed multiple distance metastases. She was referred to the gynecology team. She was scheduled for chemotherapy. However, she defaulted the treatment. 3 months after that, her general condition deteriorated. She developed bilateral internal jugular vein thrombosis and massive right pleural effusion. She passed away due to that complication. Conclusion: Choroidal metastasis from primary ovary carcinoma is very rare. Ocular symptoms can be the first presenting features to a life-threatening condition.

Choroidal metastases: origin, features, and therapy

The choroid is the most common ocular site for metastatic disease, owing to abundant vascular supply. The primary cancers that most commonly lead to choroidal metastases include breast cancer (40-47%) and lung cancer (21-29%). Bilateral, multifocal metastases are most often secondary to breast cancer, whereas unilateral, unifocal metastasis are more commonly found with lung cancer. The treatment of choroidal metastasis depends on the systemic status of the patient and number, location, and laterality of the choroidal tumors. Treatment options include observation in patients with poor systemic status or those with resolved or asymptomatic disease; systemic chemotherapy, immunotherapy, hormone therapy, or whole eye radiotherapy if the metastases are active, multifocal and bilateral; plaque radiotherapy, transpupillary radiotherapy, or photodynamic therapy for active, solitary metastasis; and enucleation for those with blind painful eye. A database search was performed on PubMed, using the terms “choroidal metastasis,” or “choroidal metastases,” in combination with terms such as “treatment,” “features,” or “diagnosis.” Relevant articles were extracted and reviewed.

Optical Coherence Tomography: An Adjunctive Tool for Differentiating between Choroidal Melanoma and Metastasis

Purpose. To investigate the value of optical coherence tomography (OCT) for differentiation between choroidal melanoma and metastasis based on characteristics of the anterior choroidal surface and the chorioretinal interface. Methods. This retrospective observational case series included 29 patients with untreated choroidal melanomas and 21 patients with untreated choroidal metastases. Regularity and lobularity characteristics of the anterior choroidal surface were evaluated in a masked manner. Retinal and retinal pigment epithelium (RPE) findings were documented as well. Results. OCT demonstrated a regular and smooth anterior choroidal surface in 89.7% of the eyes with melanoma and in 47.6% of the eyes with metastasis (p = 0.002; sensitivity = 89.7%; specificity = 52.4%). The anterior choroidal contour was lobulated in 81.0% of the eyes with metastasis versus 17.2% of the eyes with melanoma (p < 0.001; sensitivity = 82.8%; specificity = 81.0%). RPE thickness and neuroretinal characteristics (e.g., retinal thickness, the presence of cysts, and the presence of subretinal fluid) were similar in both choroidal tumors. Conclusion. OCT may serve as a noninvasive adjunctive tool for the differential diagnosis of choroidal tumors. Choroidal melanomas usually demonstrate regular surfaces on OCT, while choroidal metastases usually have an irregular and lobulated surface.

Complete Disappearance of Choroidal Metastasis from Lung Adenocarcinoma Treated with Bevacizumab and Chemotherapy

Choroidal metastasis from lung cancer is uncommon. We report a case of choroidal metastasis as an inaugural manifestation of lung adenocarcinoma, successfully treated by docetaxel, cisplatinum, and intravenous bevacizumab as an antiangiogenesis therapy. A complete remission was obtained after 4 cycles and maintained after six cycles. This case report demonstrates the importance of the systemic bevacizumab and chemotherapy in the treatment of choroidal metastasis from adenocarcinoma of the lung.
