|
Multiple yellow placoid lesions typically posterior to the equator and in the superior temporal quadrant
|
|
WORK-UP
|
Full eye exam with dilation | OCT | Fundus autofluorescence | Fluorescein angiography | ICG | Fundus photos | Infrared photos | B-scan ultrasound (Highly reflective even with reduction in gain, and associated posterior shadowing)
|
|
TREATMENT
|
No treatment needed. Monitor
|
|
Refer to PCP to rule out systemic associations (Hyperparathyroidism, Chronic renal failure, Sarcoidosis)
|
|
ADDITIONAL LAB | TESTS
|
Serum and urine levels of calcium, potassium, phosphorus, and magnesium
|
|
ETIOLOGY
|
Deposition of calcium primarily in the sclera which leads to choroidal compression and subsequent outer retina atrophy. Usually idiopathic
|
|
DIFFERENTIAL DX
|
Choroidal osteoma, Metastatic choroidal tumor, Choroidal amelanotic melanoma, Astrocytic hamartoma
