A Comparative Study of Prism Adaptation and the Augmented Surgery Formula in the Management of Acquired Comitant Esotropia.

Purpose: To compare two methods of surgical augmentation (prism adaptation and the augmented surgery formula) in the management of acquired comitant esotropia.

Methods: Forty patients were included in this prospective study and assigned to either the prism adaptation (20 patients) or augmented surgery (20 patients) group. After preoperative prism adaptation, patients in the prism adaptation group were classified as prism adaptation responders (fusers) or non-responders (non-fusers).

A conformational study of beta-phenethanolamine receptor sites. 8. Pharmacological study of 3-isopropylamino-2-phenyl-trans-2-decalols.

Two N-isopropylnorephedrines and their four possible decalol analogs were compared pharmacologically. Four of the six compounds at a concentration of 1 x 10(-4) M caused a potentiation of D(-)-norepinephrine (NE) contraction of the rat vas deferens and increased the maximal response of the preparation to NE. Pretreatment in vivo with reserpine (5 mg/kg ip) 24 hr before the experiment in vitro did not change these effects.
