Uveal melanomas arise most frequently in the choroid or ciliary body (97%) and rarely in the iris (3%). Whereas conjunctival and posterior uveal (ciliary body and choroidal) melanomas have been studied in more detail genetically, little data exist regarding iris melanomas. Methods In our ...

Iris melanomas have a better prognosis than choroidal melanomas, and it would be interesting to know if they share chromosomal changes. In addition, iris melanomas might harbour UV-induced mutations of tumour suppr...

The relatively benign behaviour of iris melanomas in comparison with the behaviour of those which develop at other sites within the uveal tract may be explained by special features of their clinical presen...

Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...
