Fig 1.
Thickness data from the map of each layer were grounded within 2 concentric circles.
The retinal areas are displayed on a fundus photograph.

Descriptive statistics of the functional and vision tests in all patients.
Table 3.
Retinal layer thicknesses measured by spectral domain optical coherence tomography in both eyes of all patients with unilateral traumatic optic neuropathy.
All measurements were significantly smaller in TON eyes than those in unaffected eyes. (Wilcoxon sign rank test).

Optical coherence tomography scan images (1:1 pixel views) showing the representative images in eyes with unilateral traumatic optic neuropathy (TON).
(A) Contralateral normal eye. (B) TON eye. (RNFL, retinal nerve fiber layer; GCIPL, ganglion cell layer and inner plexiform layer.).
Table 4.
Retinal layer thicknesses measured by spectral domain optical coherence tomography in both of patients with early traumatic optic neuropathy (within 3 weeks after trauma).
Outer superior and outer inferior GCIPL thicknesses were significantly thinner in the affected eyes than those in unaffected eyes (Wilcoxon sign-rank test).

(A) TON eye. (B) Contralateral unaffected eye. (RNFL, retinal nerve fiber layer; GCIPL, ganglion cell layer and inner plexiform layer.)
