Basically you can make it a two-step method as well which might not be the most elegant/efficient solution but at least it's working and it's damn simple.
#!/usr/bin/perl -w

use warnings;
use strict;

my $var = "abc,d";

if($var =~ /,/)
{
    print "not matches \n";
}
elsif($var =~ /(.*)/)
{
    print "matches \n Captured: $1\n";
}

$var = "abcd";

if($var =~ /,/)
{
    print "not matches \n";
}
elsif($var =~ /(.*)/)
{
    print "matches \n Captured: $1\n";
}

exit 0;

Output: 
not matches
matches
 Captured: abcd
