In the article Blood flow velocity in monocular retinoblastoma assessed by color doppler, on page 801, remove the following sentences of the RESULTS section:

“The difference persisted when considering PreONi (p=0.0088) but not PosONi (p=0.2563). ONi did not modify the arterial index Rla (p=0.9596).”

and

Replace Table 4 and its legend for:

Correlation of optic nerve invasion by the tumor with the resistivity index of the central retinal artery and the pulse index of the central retinal vein.

Optic nerve invasion was correlated with a smaller PIv; this difference persisted when considering PreONi but did not when considering PosONi. PIv=pulsatility index of the central retinal vein; RIa=resistivity index of the central retinal artery; N=without invasion; Y=with invasion; ONi=optic nerve invasion; PreONi=prelaminar optic nerve invasion; PosONi=postlaminar optic nerve invasion.

non-parametric Mann-Whitney U test.
