Ultrasound
A-scan: Medium to high internal reflectivityB-scan: Acoustic solidarity
Differential Diagnosis?
A-scan: Low internal reflectivity withreduction in amplitude. High amplitudeSpike = break in Bruch’s membrane.
B-scan: Solid mass with mushroom shape
A-scan: High internal reflectivity
B-scan: Highly reflective plate-like lesion with orbital shadowing beyond lesion
FA can help distinguish if CNV
A-scan: High internal reflectivity
B-scan: Solid elevated mass
B-scan: Thickening of the retina, choroid and sclera with fluid beneath Tenon’s capsule and squaring of optic nerve shadow
A-scan: Medium to high internal reflectivityB-scan: Acoustic solidarity
Working Diagnosis
• Is this choroidal mass with exudative detachment a primary lesion or a metastatic lesion to the choroid?
• Need thorough systemic evaluation– PCP contacted– 1 wk prior pt presented with blurred vision OD & SOB– Found to have 13cm x 15cm left breast mass– Lab Work: Liver function tests wnl– CT Chest: Breast mass, lung nodules, liver lesions– Breast Biopsy: Infiltrating ductal carcinoma, ER/PR Negative– MRI brain: Frontal, occipital, and cerebellar lesions– PET Scan: Breast mass, lung, bone, adrenal, hepatic uptake
Stage 4 Metastatic Breast Cancer
Incidence of ocular metastasis
-1872: first description of a metastatic tumor to the eye in a patient with carcinoma
-Since then realization that ocular mets are not that rare
-Bloch and Gartner (1971) 10% patients with autopsy proven carcinoma had ocular mets
- Most common intraocular malignancy- choroidal metastasis
-Hard to gauge exact incidence as patients often are asymptomatic or present with advanced CA and eye exam never performed

Shields C, Shields J, et al. Survey of 520 Eyes with Uveal Metastases. Ophthalmology 1997 1265-1273
Epidemiology
• For American women lifetime risk breast cancer- one in eight (12.5%) & lifetime risk death from breast cancer is 3.4%
• Breast Cancer is the most common malignancy to metastasize to the uvea
• Mean age at ocular diagnosis is 58 years, most cases (40-70 yrs)
• At time of ocular diagnosis 66% reported a history of a primary cancer and 34% had no history of cancer

Breast Cancer Metastases
Most Common Sites:
• Lung (71%)
• Bone (71%)
• Lymph nodes (67%)
• Liver (62%)
• Pleura (50%)
• Ocular (9%-37%)
Clinical Features Uveal MetsAppearance:
– 99% choroidal mets from breast cancer were yellow in color– 77% plateau-shaped– 65% a/w subretinal fluid– Exudation and hemorrhage rare
