In his introduction Pallin states that the present study was undertaken because of the well known fact that a convergent strabismus of moderate or low degree often decreases or even disappears at about the age of 15 and that some patients who have been operated at an early age often eventually have divergent strabismus.
The author has measured 240 skulls of newly born infants, young children, older children and youths. As a control, the measurements of 200 adult skulls (100 of male and 100 of female origin) were used.
Among the measurements made were the inclination of the two orbits to each other, the angle between the outer walls of the orbits, the angle between the inner walls of the orbits, the depth of the orbit, the biorbital width, the interorbital width, the distance between the optic foramens and the distance between the midpoints of the orbital openings.
