Kang and Ha: A Clinical Feature of the Patients of Orbital Wall Fracture With Diplopia

Abstract

Purpose

To analyze the clinical features of orbital wall fracture with diplopia between the surgical treatment group and the conservative treatment group.

Methods

The study comprised of 109 eyes of 109 patients with orbital wall fracture and diplopia. The patients were divided into two groups: the surgical treatment group (59 cases) and the conservative treatment group (50 cases). The groups were analyzed retrospectively according to age, gender, cause, CT, the period and severity of diplopia, and enophthalmos with time.

Results

In the conservative treatment group, 38 cases (64.4%) had medial wall fracture, and the average fracture size was 26% of the inferior wall and 33% of the medial wall. In addition, at the first visit, the patients showed diplopia within 45.5 degrees, and diplopia disappeared completely within 17 days on average (57 cases, 96.6%). In the group that underwent the reconstruction of orbital wall fracture, 27 cases (54.0%) had inferior wall fracture, and the average fracture size was 41% of the inferior wall and 35% of the medial wall. Additionally, in the first visit, the patients showed diplopia within 20.3 degrees. The muscle incarceration occurred in 12 cases (24%). In the surgical treatment group, diplopia disappeared completely within 30 days on average (45 cases, 90.0%).

Conclusion

In the group of conservative treatment, they showed diplopia within 45.5 degrees at the first visit. Diplopia disappeared completely within 17 days on average (57 cases, 96.6%). In the group of surgical treatment, they showed diplopia within 20.3 degrees at the first visit. Diplopia disappeared completely within 30 days on average (45 cases, 90.0%).
