The History of Iris-diagnosis: Before commencing the study of Iris-diagnosis, it is necessary to clarify two terms which are always being confused: Iris-diagnosis and Eye-diagnosis. These two terms are not synonymous. Iris-diagnosis is the observation and diagnosis of disease from the iris, and is sometimes referred to as Iris-copy. Eye-diagnosis is the observation and diagnosis of diseases affecting the whole eye, including the pupil and iris, and the immediately surrounding parts. Strictly speaking, this should be referred to as Ophthalmoscopy.
