Analysis of prognostic factors of endoscopic optic nerve decompression in traumatic blindness.

CONCLUSIONS

Hemorrhage within the ethmoid and/or sphenoid sinus and an interval between the time of injury and the time of operation exceeding 3 days are the risk factors for the visual prognosis of traumatic blindness.

OBJECTIVES

To investigate the therapeutic efficacy of endoscopic optic nerve decompression in the treatment of traumatic blindness and to evaluate the relevant prognostic factors.

METHODS

Eighty-five cases of traumatic blindness were analyzed retrospectively. Univariate analysis and multiple logistic regression were performed to evaluate potential prognostic factors.

RESULTS

The overall rate of vision acuity improvement was 44.7% (38 of 85). Univariate analysis indicated that hemorrhage within the ethmoid and/or sphenoid sinus was significantly associated with unrecovered visual acuity. However, multiple logistic regression analysis identified that an interval between the time of injury and the time of operation exceeding 3 days, and hemorrhage within the ethmoid and/or sphenoid sinus were significantly correlated with the efficacy of treatment of traumatic blindness.
