Metastatic carcinoma to the vitreous: An optical coherence tomography and ultrawide field imaging study

摘要

It is quite rare for carcinomas to metastasize to the retina, and only a few cases have been reported in the literature. Nevertheless, metastatic carcinoma to the choroid has been well described. Although imaging technology (e.g. optical coherence tomography [OCT] and ultrawide field retinal imaging) has rapidly advanced, the metastatic invasion process of a carcinoma to the eye has rarely been documented on OCT5 and has never been documented on Optos ultrawide field imaging (Optos PLC, Dunfermine, Scotland). Here, we present a case where an oesophageal carcinoma metastasized to the retina, as documented on spectral-domain OCT and Optos ultrawide field imaging. A 70-year-old man was referred to our institution because of complaints of increased floaters in the left eye for 3 months. He had a history of surgery for oesophageal carcinoma and was undergoing chemo- and radiation therapy for pulmonary and thoracic lymph node relapse. His visual acuity was 6.0/4.8 in both eyes. Fundus examination revealed a vitreous opacity, which contained minute particles, and was localized to the peripheral retina (Fig. la).
