T = Thickness (Elevation > 2mm)
F = Fluid (subretinal)
S = Symptoms (blurred vision, float)

O = Orange pigment (lipofuscin)
M = Margins (irregular borders)
UH = Ultrasonographic hollowness (low reflectivity = evil so lying low)

associated with a lower risk of malignant transformation) (Diameter >
4DD or 6mm) or close to optic nerve

1.5 mm = 1DD
