More
An amblyoscope is also known as an orthoptoscope. It measures the angle of a squint in the eye and determines how well both eyes work together. Squint is historically referred to by the term strabismus. It is a condition in which the eyes are not properly aligned with each other. It is most common in young children. The prisms within this instrument can be moved independently to assess the severity of the squint.
