  We present Adaptive Optics (AO) near infrared (NIR) observations using
VLT/NACO and Keck/NIRC2 of ODISEA targets. ODISEA is an ALMA survey of the
entire population of circumstellar discs in the Ophiuchus molecular cloud. From
the whole sample of ODISEA we select all the discs that are not already
observed in the NIR with AO and that are observable with NACO or NIRC2. The
NIR-ODISEA survey consists of 147 stars observed in NIR AO imaging for the
first time, as well as revisiting almost all the binary systems of Ophiuchus
present in the literature (20 out of 21). In total, we detect 20 new binary
systems and one triple system. For each of them we calculate the projected
separation and position angle of the companion, as well as their NIR and
millimeter flux ratios. From the NIR contrast we derived the masses of the
secondaries, finding that 9 of them are in the sub-stellar regime (30-50
\MJup). Discs in multiple systems reach a maximum total dust mass of $\sim$ 50
M$_{\oplus}$, while discs in single stars can reach a dust mass of 200
M$_{\oplus}$. Discs with masses above 10 M$_{\oplus}$ are found only around
binaries with projected separations larger than $\sim$ 110 au. The maximum disc
size is also larger around single star than binaries. However, since most discs
in Ophiuchus are very small and low-mass, the effect of visual binaries is
relatively weak in the general disc population.
