Visual-Evoked-Response-Supported Outcome of Intravitreal Erythropoietin in Management of Indirect Traumatic Optic Neuropathy

Table 5

Comparisons of improvement of BCVA, VER latency, and amplitude between patients of recent and old TON trauma.

Improvement in:	Trauma <3 months	Trauma ≥3 months	value
BCVA (logMAR) (mean ± SD)	0.72 ± 0.3	0.4 ± 0.26	0.07
≥2 lines	100%	86%	0.95^††
≥3 lines	86%	57%	0.56^††
VER amplitude (mean ± SD)	2.76 ± 4.3	4.36 ± 4.45	0.56
VER latency (mean ± SD)	35 ± 67.5	30.3 ± 25.7	0.87

BCVA (Log MAR): best-corrected visual acuity in LogMAR. VER: visual evoked response. Unpaired two tail t-test. ^††Fisher’s exact test.
