Echothiophate iodide cataracts in monkeys. Occurrence despite loss of accommodation induced by retrodisplacement of ciliary muscle

Archives of Ophthalmology

Abstract

Five cynomolgi underwent unilateral 360 degrees ciliary muscle retrodisplacement. Beginning several months later, they received 150 to 210 micrograms of echothiophate iodine topically once daily in both eyes for five months. In all eyes anterior and posterior subcapsular lens opacities developed that were characteristic of those caused by echothiophate. There were no apparent differences in biomicroscopic appearance or time course of the cataracts between eyes with or without retrodisplaced ciliary muscles. Since eyes with retrodisplaced ciliary muscles accommodate only minimally in response to echothiophate, possible mechanical stress on the lens due to sustained, intense accommodation cannot explain echothiophate cataractogenesis.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
