Comparison of clinical characteristics of familial and sporadic acquired accommodative esotropia.

Purpose: To compare the clinical characteristics of patients with familial and nonfamilial acquired accommodative esotropia.

Methods: We recruited 48 patients from 33 families with acquired accommodative esotropia (an inward deviation of the eyes of 10 PD or more, a hypermetropia greater than or equal to +1.50 D, and an onset of esotropia at, or later than, 1 year of age).

Viscosity regulation by surfactants.

Synopsis The viscosity of cosmetic emulsions is of great practical importance and related to their skin feel. To achieve a desirable and constant viscosity is not an easy task because numerous factors must be considered. Based on theoretical considerations a new surfactant, steareth-5-stearate, has been developed.
