Choroidal Metastasis in Stage IV Lung Adenocarcinoma.

Abstract

It is known that the incidence of lung cancer is increasing rapidly in both men and women. While no ocular findings may be observed in the early stage, ocular involvement may be observed in the advanced stage. The choroid is the most common site of intraocular metastasis in adults due to its rich vascularisation. In this report, a 52-year-old woman was referred to our clinic because of retinal detachment detected in an external center with complaints of flashes of light in the left eye 3 months ago and decreased vision for the past week. It was learned that she was diagnosed with advanced stage (stage IV) adenocarcinoma of the lung and received chemotherapy at regular intervals due to distant metastasis (liver and bone). Biomicroscopic fundus examination, B-Mode ultrasonography, fundus fluorescein angiography, and orbital magnetic resonance imaging revealed a choroidal mass. The current clinical picture was interpreted as distant metastasis of lung adenocarcinoma, no surgical intervention was planned for the secondary exudative retinal detachment, and the patient was consulted by the oncology clinic. In addition to chemotherapy, three cycles of radiotherapy were given within 1 week and the mass disappeared at the follow-up visit 2 months later. In the differential diagnosis of retinal detachment, metastasis of a diagnosed primary tumor should be considered as in our case. Early detection of these metastatic lesions and appropriate treatment strategies will prevent unnecessary vitreoretinal surgeries and complications.
