There might be better ways to do this. Here is one way (not very clean tho) 


use strict;
use warnings;

my $x = 10; 
my $y = undef; 
my $check = '$x,$y'; 
my @vars = split /,/,$check; 
for (@vars) { 
    if (defined(eval($_))) { 
        print "$_ = Defined\n"; 
    } else { print "$_ = Not defined\n";}
}
__END__
$x = Defined
$y = Not defined

There are risks associated with eval so you need to watch out
