Excerpt from On Cataract, and the Operation for Its Removal by Absorption: With the Fine Needle Through the CorneaIT is scarcely necessary to state that cataract is the name given to that disease of the eye in which blindness is caused by loss cf transparency in the crystalline lens, and under that name, therefore, all opacities whatever of that part should be considered. Certain appearances, generally accompanied by defective vision, have been denominated glaucoma, but if it is meant to attribute these appearances and the defective vision which accompanies it to any loss of transparency in the crystalline lens, the term should not be used, the disease being in that case only a form of cats, raet. The application of two different names to the same disease is calculated to create confusion. I am not here, however, going to inquire what the disease called glaucoma is, I only want to have it settled that it is not cataract, or that if it is, it should be so called.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
