PURPOSE. To report the long-term outcome of patients with indirect traumatic optic neuropathy (TON) which showed useful vision for a short period after trauma. METHODS. A cohort of 12 TON patients treated with steroids megadose immediately after trauma was followed every 6 months for an overall period of 5 years. Other than a full neuro- ophthalmologic examination, each visit included quantitative Goldmann perimetry and pattern reversal visual evoked potentials. The results of each examination were compared with the visual function at baseline. The main outcome measures were visual acuity and visual field. Data were analyzed using the Wilcoxon signed-rank test. A p value of less than 0.05 was considered statistically significant. RESULTS. All patients showed a stable visual function 5 years after optic nerve trauma. There was no difference in visual acuity levels (p=0.65) and no visual field surface area between the visit at baseline and the last follow-up. However, a significant improvement in visual field extension (p=0.036) was observed after perimetry evaluation. CONCLUSIONS. This cohort of patients clearly demonstrates that the residual visual function found in the short term after TON is maintained for at least 5 years. These findings add further important clinical information for patients with TON. Furthermore, these data may be helpful to better quantify morbidity related to optic nerve trauma and its permanent sequelae

Abstract

PURPOSE. To report the long-term outcome of patients with indirect traumatic optic neuropathy (TON) which showed useful vision for a short period after trauma. METHODS. A cohort of 12 TON patients treated with steroids megadose immediately after trauma was followed every 6 months for an overall period of 5 years. Other than a full neuro- ophthalmologic examination, each visit included quantitative Goldmann perimetry and pattern reversal visual evoked potentials. The results of each examination were compared with the visual function at baseline. The main outcome measures were visual acuity and visual field. Data were analyzed using the Wilcoxon signed-rank test. A p value of less than 0.05 was considered statistically significant. RESULTS. All patients showed a stable visual function 5 years after optic nerve trauma. There was no difference in visual acuity levels (p=0.65) and no visual field surface area between the visit at baseline and the last follow-up. However, a significant improvement in visual field extension (p=0.036) was observed after perimetry evaluation. CONCLUSIONS. This cohort of patients clearly demonstrates that the residual visual function found in the short term after TON is maintained for at least 5 years. These findings add further important clinical information for patients with TON. Furthermore, these data may be helpful to better quantify morbidity related to optic nerve trauma and its permanent sequelae
