NTM concentrations (μg/g) in cornea, ICB, AH, and VH from NTM-PNLC-GEL (dose: 0.3 mg; instillation volume: 100 μL), NTM-PNLC (dose: 0.3 mg; instillation volume: 100 μL), and Natacyn (dose: 5 mg; instillation volume: 100 μL) obtained after instillation every 3 and 4 h for a 9- and an 8-h study, respectively. *Denotes statistically significant difference at P < 0.05 (n = 3, data represented as mean ± standard error). AH, aqueous humors; ICB, iris-ciliary bodies; VH, vitreous humors.
