The Melbourne Renegades all-rounder was struck in the face by a Lasith Malinga thunderbolt on Sunday night after he top-edged an attempted hook shot.
Captain Aaron Finch said after the match the West Indian star had a suspected fractured eye socket and the Renegades have maintained since that no update is available because swelling across the bridge of his nose is too severe for a more specific assessment.
But it is understood Samuels has been ordered by doctors to remain as still as possible to avoid the chance of permanent damage to his vision.
He will likely not leave his hotel room for weeks until given the medical all-clear and almost certainly miss the West Indies’ tour of Australia next month.
Samuels, at the centre of Sunday night’s Big Bash League blow-up with Shane Warne, faces two disciplinary charges for his part in the controversial clash with the Melbourne Stars.
But as a pointer to the growing concerns for his injury, Cricket Australia is yet to set a time for the hearing

The injury-hit Renegades yesterday recruited an urgent international replacement for Samuels, signing giant English opener Alex Hales.
Hales will arrive in Sydney today in time to join the Renegades for their last home-and-away match against the Sixers at the SCG before their home semi-final next Tuesday.
The Renegades are guaranteed to finish top of the ladder, regardless of the results of the closing round of BBL preliminaries, but need to play Hales tonight to qualify him for the finals.
In another guide to the severity of Samuels’ injury, coach Simon Helmot, who along with other Renegades officials spent much of Sunday night in hospital with the Jamaican, yesterday wished “him all the best for a speedy recovery”.
“He’ll be devoting his energies to getting himself right again before returning home to Jamaica,” Helmot said.
The coach said Hales was already “an accomplished T20 batsman who has taken apart international attacks all over the world”.
Hales averages 34.83 at a strike rate of 127.43 in 14 T20 internationals for England. His most recent T20 outings in national colours netted 56 and 42 against India in December.
