Summary of Changes

Iris

  • T1 lesions have been divided into T1a, T1b, and T1c.

  • T1a is denned as tumor limited to the iris not more than 3 clock hours in size.

  • T1b is denned as tumor limited to the iris more than 3 clock hours in size.

  • T1c is defined as tumor limited to the iris with melanomalytic glaucoma.

  • The definition of T2 lesions has been modified, and T2 has been divided by the addition T2a.

  • T2 is defined as tumor confluent with or extending into the ciliary body and/or choroid.

  • T2a is defined as tumor confluent with or extending into the ciliary body and/or choroid with melanomalytic glaucoma.

  • The definition of T3 lesions has been modified, and T3 has been divided by the addition T3a.

  • T3 is defined as tumor confluent with or extending into the ciliary body and/or choroid with extra scleral extension.

  • T3a is defined as tumor confluent with or extending into the ciliary body with extrascleral extension and melanomalytic glaucoma.

Ciliary Body and Choroid

  • The definition of Tl lesions has been modified, and Tl has been divided into Tla, T1b, and T1c.

  • T1 is defined as tumor 10 mm or less in greatest diameter and 2.5 mm or less in greatest height (thickness).

  • T1a is defined as tumor 10 mm or less in greatest diameter and 2.5 mm or less in greatest height (thickness) without extraocular extension.

  • T1b is defined as tumor 10 mm or less in greatest diameter and 2.5 mm or less in greatest height (thickness) with microscopic extraocular extension.

  • T1c is defined as tumor 10 mm or less in greatest diameter and 2.5 mm or less in greatest height (thickness) with macroscopic extraocular extension.

  • The definition of T2 lesions has been modified, and T2 has been divided into T2a, T2b, and T2c.
