Small choroidal tumors can be the hardest ones to distinguish. They often have not had the time to develop the most common distinguishing characteristics: Orange pigment, Subretinal Fluid and Thickness greater that 2 mm. However, Dr. Finger's mnemonic device MOST helps us remember them, where Melanoma = Orange pigment, Subretinal Fluid and Thickness > 2 mm.

There are other findings, but those are the most common and when seen together are diagnostic.
