·      Choroidal  melanoma  may  perhaps  remain  unobserved  below  a  sub-retinal

               hemorrhage, a huge exudative retinal detachment, or a vitreous hemorrhage

            ·      Transscleral  development  of  a  frontal  choroidal  melanoma  (primarily  via

               emissary paths) may come into view on examination as a small sub-conjunctiva

               part of atypical hyperpigmentation

            ·      Frontal choroidal melanomas may possibly show sentinel vessels that nurture

               the metabolically active tumor





                                   DIAGNOSIS OF CHOROIDAL MELANOMA



               Nearly all cases of choroidal melanoma are discovered during a regular,

               dilated eye exam. During this exam, an eye consultant or specialist

               (ophthalmologist) widens the pupils to inspect the back of the eye. Most of the

               time, no other tests are required. But specified tests can prove the diagnosis.

               These tests consist of



            ·      Ultrasound. A little probe positioned on the eye directs sound waves in relation

               to the tumor. A machine records the patterns the waves produce as they bounce

               off the tumor.



            ·      Fluorescein angiography. A fluorescent dye is infused into the vein of an arm. A

               rapid  series  of  photographs  is  captured  through  the  pupil  as  the  dye  goes

               through the veins in the rear of the eye.
