    7. In-vivo imaging for assessing tumor growth in mouse models of ocular melanoma

      In-vivo imaging for assessing tumor growth in mouse models of ocular melanoma
      Uveal melanoma (UM) and conjunctival melanoma (CM) are ocular malignancies that give rise to life-threatening metastases. Although local disease can often be treated successfully, it is often associated with significant vision impairment and treatments are often not effective against metastatic disease. Novel treatment modalities that preserve vision may enable elimination of small tumors and may prevent subsequent metastatic spread. Very few mouse models of metastatic CM and UM are available ...
