Eyes Versus Faces: Morphologic Characteristics of Human Eyes in Different Facial Forms

Objective: To evaluate the static eye characteristics of female patients with short, normal, and long faces. Methods: Standardized full face frontal photographs of 163 female patients in the age range of 15 to 25 years were screened to evaluate their facial index (FI). Based on FI, 27 were short face (group I), 31 were normal face (group II), and 26 were long face (group III) photographs. All 84 photographs were then analyzed manually to determine various static eye characteristics. Descriptive statistics, 1-way analysis of variance and posthoc test (Bonferroni) for multiple comparisons were used. AP-value of 0.05 was considered as level of significance. Results: The eye index was significantly different in group I, group II, and group III patients (P < 0.001). The position of the eyes in relation to width of face was significantly less in short (P < 0.05) faces and more in long (P < 0.001) faces compared to normal faces. The intereye distance was equal to the length of 1 eye in all 3 types of faces. Among all types of faces, the intereye distance was nearly half of the interpupillary distance and approximately one-fourth of the face width. The eye divergence was significantly less in long faces compared to short (P < 0.001) and normal faces (P < 0.05). Conclusion: The static morphologic characteristics of eyes were significantly different among females with different facial morphologies.
