Purpose:
To report the swept-source optical coherence tomographic (OCT) findings in two eyes with choroidal metastases.
Observations:
Two patients with choroidal metastasis were studied. The metastasis was from a breast cancer in Case 1 and from a lung cancer in Case 2. In Case 1, swept-source OCT showed a highly reflective solid tumor with low optical reflective tissues that had replaced the choroidal tissue. Swept-source OCT was able to image the choroidal mass where other fundus imaging methods such as fluorescein angiography did not show the mass. Ophthalmoscopy of Case 2 showed hemorrhages in the inner retina, on the tumor, and in the vitreous. Swept-source OCT showed a subretinal mass with a steeple-crowned cap and a ruptured Bruch's membrane on the tumor.
Conclusion And Importance:
Swept-source OCT imaging can detect the inner structure of a choroidal mass and retina around it in good detail.
