The permeability of the corneal endothelium to fluorescein in the normal human eye

Abstract

Endothelial permeability to fluorescein was measured as part of fluorophotometric studies of aqueous humor flow in 112 normal subjects whose ages span 6 decades. The permeability was 2.4 .+-. 0.9 .times. 10-4 cm/min (mean .+-. SD). Females had a slightly higher permeability than males. No correlation between age and permeability was noted. The precision of this method of measurement was .+-. 22%.
