Experimental design. BALB/c mice were inoculated into the right eye subretinal space with aliquots of B16F10 or B16LS9 cells (10² cells/1 μL PBS). Each experimental tumor model was divided into mice given tap water with propylene glycol (Control group) or to mice given drinking water containing tetrac (Experimental group). The number of mice in each group is indicated. The mice were monitored on a daily basis and first sign of intraocular tumor growth was recorded. The mice were followed-up and recorded for tumor initiation for 37–40 days.
