Clinical features

  • Dilated blood vessels in the overlying episclera ('sentinel vessels')
  • Visible tumour behind the pupil
  • Secondary retinal detachment
  • Lens complications, such as indentation, astigmatism, subluxation and cataract
  • Secondary glaucoma, from angle involvement by tumour or melanomacrophages or as a result of neovascularisation.

  • Circumferentially within the ciliary body to form a 'ring tumour'
  • Anteriorly, into anterior chamber, becoming visible on slit-lamp examination
  • Posteriorly, into choroid
  • Extraocularly, to form a sub-conjunctival, pigmented nodule or an area of diffuse pigmentation.
