“Analysis of intraocular tissue ascorbate indicated that propranolol inhibited ascorbate secretion at the 3000 microg dose, the highest dose examined in this study; this inhibition was not observed at the 750 microg or 1500 microg doses.”
“ Propranolol (1500 microg) produced significant increases in aqueous humor ascorbate , this observation is consistent with a reduction in aqueous humor production (approximately 47%).”
