Abstract

To investigate the relationship between surgical approach for intraocular tumor biopsy of uveal melanoma and tumor morphologic features such as size and intraocular location and the effect of these variables on diagnostic yield and biopsy outcome.Consecutive patients from nine Ocular Oncology centers with uveal melanoma (UM) undergoing tumor biopsy immediately preceding I125 plaque brachytherapy with tissue sent for gene expression profiling (GEP) testing were reviewed retrospectively.Three hundred sixty patients were included (50% men, mean age 60.2 years). Overall biopsy yield was 99% and 83% for GEP and cytopathology, respectively. Surgeon choice of biopsy approach (trans-vitreal vs. trans-scleral) was found to associate with both tumor location and tumor thickness. A trans-scleral rather than trans-vitreal approach was used more commonly for anteriorly located tumors (92% vs. 38% of posterior tumors, p
