Significantly larger than the anterior chamber value as paired data, P<0.001. Rabbits were pretreated with bilateral, topical applications of 0.5% proparacaine HCl. After 15 min, 30 μl and 50 μl of aqueous were drawn from the posterior and anterior chambers respectively as described by Kinsey (1953). Twenty microliter aliquots of these samples were used in the ascorbate assay of Liu et al. (1982). In two cases the aqueous samples were not used because the iris was punctured; injured rabbits were immediately sacrificed by placement under general anesthesia and CO2 asphyxiation.
