Regression analysis to analyze the association of TGV and potential decline of VA in any eye during follow-up showed no significant correlation between tumor growth rate and change in logMAR when all patients or patients with NF-1 were included (R2 = 0.11, p = 0.09 and R2 = 0.16, p = 0.12, respectively). This evidence concerns the gene NF1 and neoplasm.
