Option immediately followed by a number

I want to match a string composed of "-n" immediately followed by a number.  
Meaning at least one number after "-n".

For instance "-n8", "-n21", "-n34"

How can I make a glob pattern that matches the above description that I can use 
with the case statement?

case $opt in
  ("-n") do-this ;;
esac
