A doctor can use cryotherapy to freeze the skin tag off. In addition, the skin is weighed down by the effect of gravity. Using progression analysis for nonglaucomatous field loss should be limited to VFI linear regression/trend analysis (the GPA change probability was designed for use in glaucoma).
