Four measurements and two qualitative signs related to the orbits of 145 adult Caucasian cleft lip/palate patients operated on in childhood were compared with similar data on 100 normal Caucasian Canadians. The average interorbital distance in male patients with unilateral and bilateral cleft lip/palate was greater than in controls, while the interorbital distance in both male and female patients with isolated cleft palate was the same as that in controls. A hypertelorism increased interorbital distance of greater than 2 S.D. above the normal was recorded in 10 cleft patients out of 145, the maximum in male cleft patients being 48 mm and in female cleft patients 38 mm. Orbital eye fissure length asymmetry was seen only in the cleft study group while a dislocation of the eye fissure levels in the frontal plane was found both in patients with clefts and in controls. No direct relationship was found between the extent of the cleft and the incidence of hypertelorism, nor between the site of the cleft and eye fissure asymmetry in unilateral cleft lip/palate patients. The epicanthic fold was significantly more frequent in cleft lip/palate patients (28/145) than in controls (10/100). Anti‐mongoloid eye fissure type was recorded only in patients with cleft but mongoloid eye fissure was present both in patients with clefts and controls.
