Differences in interpalpebral fissure measurement in patients with unilateral enophthalmos resulting from orbital wall fractures

Abstract

Purpose: To determine the correlation between the degree of enophthalmos and interpalpebral fissure (IPF) measurements in a group of patients with unilateral orbital wall fractures.

Materials and methods: The medical charts of 45 patients diagnosed with unilateral enophthalmos resulting from an orbital wall fracture were reviewed. Demographic characteristics were investigated, including patient age, sex, medical history, and type of orbital wall fracture. The correlation between the degree of enophthalmos and IPF was determined, adjusting for confounding demographic factors.

Results: In the group with orbital wall fractures, the correlation between the degree of enophthalmos and the IPF measurements was positive and significant (R = 0.299, p = 0.046, Pearson's correlation). The correlation coefficient increased after adjusting for age, sex, medical history, and type of orbital wall fracture (R = 0.316, p = 0.044).

Conclusion: The patient group with more severe enophthalmos tended to have lower IPF values.
