Size Determination

Your doctor will classify any found ocular melanoma tumor by the degree of pigmentation of the tumor, its shape and location, and by other features observed during the examination.

The size of the tumor is a large factor in the treatment protocol:
  • Small: 1.0-2.5mm in height; greater than 5mm at the base
  • Medium: 2.5 - 10mm in height; less than or equal to 16mm at the base
  • Large: greater than 10mm in height; greater than 16mm at the base
