title: [Intraocular light transmission characteristics using a microfiber system].
abstract: There have been some reports about light transmission into the vitreous, but few that have been measured directly in vivo. The author attempted to measure visible light and ultraviolet light using a microfiber system in the vitreous. Microfibers 0.6 mm in diameter were made. The microfiber system can be inserted into the vitreous at the pars plana and can measure the characteristics and intensity of the transmitted light. We used rabbit, monkey and aphakic rabbit eyes in this study. The light transmission into the vitreous of normal rabbits and monkey eyes gradually decreased from 400 nm to 360 nm, but the light transmission of the aphakic rabbit eyes did not distinctly decreased. This tendency was found in vivo and in vitro. It was considered that this system is useful to determine the light transmission characteristics of various eye conditions.
