Brief summary
Approximately 300 patients presenting orbital blow-out fracture will be enrolled prospectively in this registry. All patients, surgically and nonsurgically treated as per standard (routine) of care will be followed-up (FU) within the registry for a period of 6 months.
Detailed description
Approximately 300 patients presenting with a displaced orbital fracture (OFx) in the floor and/or medial wall (blow-out fracture) will be enrolled prospectively in this registry. All patients, surgically and nonsurgical treated will be followed-up (FU) within the registry. FU period for all patients will include assessments post-treatment at 6 weeks, 3 months and 6 months as corresponding with the local standard (routine) visit schedule at each participating clinic. Data collection includes patient and fracture details, treatment details, functional, clinical and patient-reported outcomes and anticipated or procedure- and implant-related adverse events (ie, complications). Computer Tomography (CT) scans or Cone Beam-CT (CBCT) scans taken as per standard of care will be collected within the registry.
Interventions
PROCEDUREPrimary early reconstruction
Primary surgical reconstruction of the fracture within 3 weeks after injury
OTHERNonsurgical
Nonsurgical treatment of fracture
PROCEDUREPrimary delayed reconstruction
Primary surgical reconstruction of the fracture more than 3 weeks after injury
PROCEDURESecondary reconstruction
Second surgical reconstruction of the fracture after a primary reconstruction.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diplopia | 24 weeks post-treatment | The degree of diplopia is quantified by measuring the field of single binocular vision, ranging from 0 to 3. 0: no diplopia 1. mild (diplopia appears more than 30 degrees from the primary position) 2. moderate (diplopia appears between 10 and 30 degrees from the primary position) 3. severe (diplopia appears within 10 degrees from the primary position) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Globe position | 6, 12, 24 weeks post-treatment | Exo/enophthalmos (in mm) using Naugle or Hertel exophthalmometer Hyper/hypophthalmos: vertical globe displacement is measured as the pupilar height difference (in mm) from the healthy side to the injured side |
| Visual acuity | 6, 12, 24 weeks post-treatment | Measured using a visual test chart in healthy and injured sides with and without vision aids. |
| Extra-ocular mobility | 6, 12, 24 weeks post-treatment | Follow-my finger test |
| Patient-reported outcomes | pre-treatment, 6, 12, 24 weeks post-treatment | AOCMF Injury symptom battery Self-reported diplopia Self-perception of visual acuity, strabismus and symmetry |
