* Eye donor: A. tigrinum larvae; transplants were orthotopic and orthopositional to natural eye's configuration.
**Data of camouflage-incompetent subjects were excluded from analyses.
***Comparison between Xenograft and Autograft means: significant difference (P/0.05 = 2.042 ).
****Comparison between Autograft and One-Eye means: insignificant difference (P/0.05 = 2.056)
