Background/Aims:
To ascertain factors associated with persistent diplopia after orbital fracture reconstruction.
Methods:
In this retrospective study, we reviewed 798 cases with depressed fragment fracture at the Department of Kyoto Prefectural University of Medicine Hospital between January 2009 and November 2023. The restriction of extraocular movements and diplopia was assessed using the Hess area ratio (HAR). The factors for HAR% ≥85% before surgery and 6 months after surgery were assessed.
Results:
Of the 798 cases in this study, 437 cases (54.8%) had an HAR% of ≥85%, and 361 cases (45.2%) had an HAR% of <85% before surgery. Age ≤18 years old (p=0.017), orbital tissue herniation volume
Conclusion:
Patients of younger age, male and those with absence of extraocular muscle deviation have better eye movements in the affected eye (increased HAR%) 6 months after surgery.
