Clinical Investigations on Squint

"Clinical Investigations on Squint" by C. Schweigger is a detailed study about strabismus, also known as squinting, from the 1800s. The study dives into why squinting happens, different kinds of it, and what it means for someone's vision. It looks at both convergent and divergent squint and shares facts and observations from real patients. The study starts by explaining how complicated squinting is and then looks at different types like ordinary, periodic, paralytic, and typical squint. The author also points out that it's important to tell the difference between real squinting and when it just looks like someone is squinting, while addressing visual axes' deviation. The text suggests a deep study of how squinting relates to problems with seeing clearly and how to treat it, which makes the tone serious and insightful.
