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:

Table 4
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.
