Excerpt from On Cataract, and the Operation for Its Removal by Absorption: With the Fine Needle Through the Cornea
It is scarcely necessary to state that cataract is the name given to that disease of the eye in which blindness is caused by loss of 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 cataract. 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.
Notwithstanding all that has been already written on the subject, I think it is necessary to preface what I have to say respecting changes in structure of the crystalline lens by a description of that part in its natural and healthy state.
