[Role of the sympathetic nervous system in the pathogenesis of experimental glaucoma]

It has been shown in experiments on rabbits that alpha-and beta-adrenoblockers, and lithium chloride solution exert different effect on intraocular tension of healthy animals with experimental glaucoma and transitory hypertension. The beta-blockker obsidan decreases the tension in experimental glaucoma. Pretreatment with the drug prevents the development of glaucoma. On the contrary, the alpha-blocker pirroxan promotes the development of glaucoma and does not elicit any hypotensive therapeutic effect. The drug-induced decrease in intraocular tension was recorded in healthy animals and in rabbits with transitory hypertensin of the eye. The hypotensive effect of lithium was noted only in the animals with experimental glaucoma. The role of alpha-and beta-adrenergic receiption in the pathogenesis of glaucoma is discussed.
