On the Relationship of Eso to Exo-troptia in Newcastle

Patricia Dunlop, DBO (D)

All cases of manifest horizontal deviation presenting during 1980 in a solo Australian private orthoptic practice were analysed in relation to type of deviation, type of onset, age, race, sex, refractive error, amblyopia, concomitance, constancy and delay in presentation. The 1980 incidence of eso and exo deviation was compared with the figures from the same solo practice over the previous 25 years.
