Relationships among, body weight, eye weight, axis lengths, and age in normal and mutant mice. Mice were sacrificed at various ages. The left eye was enucleated first, fat was trimmed from the globe and eye weight and lengths on three axes were measured. This was repeated for the right eye. The time between left eye removal and right eye measurements was about 5 min. Panel A: Eye weight compared to age. Panel B: Eye weight compared to body weight. Panel C: N-T lengths compared to eye weight. C57BL/6J wild type mice are identified by triangles and rd10 by circles. Left eyes are represented by filled symbols and right eyes by open symbols.
