thus , the biochemically measured loss of irbp appears to be a complex process neither directly dependent on the loss of photoreceptor outer segments and reduced interphotoreceptor matrix space ( e.g . there is a sustained irbp level in rodless rds mutants ) nor simply due to cell death ( e.g . in the rd/rd , rds/rds mutant , irbp loss significantly precedes cell loss ) .
