Abstract:
PURPOSE: We compared ocular torsion rates in blow-out fracture patients before and after blowout fracture repair by analyzing mean disc foveal angles. METHODS: The study participants were divided into 2 groups: blow-out fracutre repair patients (n = 36) and controls (n = 36). We measured ocular torsion rates by analyzing mean disc foveal angle. The angle was composed of 2 imaginary horizontal lines which crossed the optic disc center and fovea. We compared statistically ocular torsion rates in blow-out fracture patients based on subsided diplopia, continued diplopia, or absence of diplopia before and after blow-out fracture repair using paired t-test. RESULTS: In the patient group, ocular torsion rates were statistically significantly decreased. In the blow-out fracture repair group with subsided diplopia, ocular torsion rates were decreased statistically from 7.74 +/- 3.48 degrees before blow-out fracture repair to 5.02 +/- 3.11 degrees after blow-out fracture repair. In the blow-out fracture repair group with continued diplopia or absence of diplopia before surgery, ocular torsion rates did not change statistically significantly from 6.36 +/- 2.80 degrees before blow-out fracture repair to 6.51 +/- 3.24 degrees after blow-out fracture repair. CONCLUSIONS: Subsided diplopia after blow-out fracture repair and ocular torsion rate changes were significantly related in blow-out fracture patients. Further research which on the correlation of intraorbital change and movement of orbital position after blow-out fracture repair with ocular torsion rates are necessary.
