Résumé
Persistent diplopia following orbital fracture is a well-recognized problem. While observation is the standard-of-care, symptoms may be protracted. Orthoptic vision therapy is a form of ocular physical therapy that achieves functional rehabilitation through targeted exercises. This study presents a protocol for post-traumatic orthoptics and describes preliminary results. Protocols for home-therapy/office-assessment were developed using commercial software and exercises targeting motility and fusion. Office-assessment also included validated questionnaire chronicling symptomatology. Healthy-volunteers (n = 10) trailed the protocol three times (n = 30) and normative data was compiled. Comparative measurements were made in chronic (>1year; n = 8) and acute (<2 weeks; n = 4) fracture cohorts. Time-of-therapy was recorded, monetary cost-analysis performed, and side-effects assessed. Severe/moderate motility limitation was found in 3 of 4 acute fracture patients but not in chronic or healthy cohorts. The acute cohort had worse fusion when comparing convergence (mean break/recovery of 8.0/6.5 prism diopters (pd) versus 31.87/21.23pd; P = 0.001/0.015) and divergence (3.00/1.50pd versus 18.37/12.83pd; P = 0.000/0.001) to the healthy cohort. Those with chronic fracture had lower convergence (15.71/5.00pd; P = 0.01/0.001) and divergence (12.29/4.71pd; P = 0.04/0.002) when compared with healthy subjects, but better function than acute patients. Acute fracture patients reported greater symptomatology than chronic (mean score 18.8 versus 4.6; P = 0.003) or healthy (5.0; P = 0.02) groups, but there was no difference between chronic and healthy groups (P = 0.87). Assessment took <10 minutes. Per patient software cost was <$70. Mild eyestrain related to therapy was self-resolving in all cases. Orthoptic therapy may improve fusion and motility following orbital fracture. This protocol serves as basis for prospective work.
