Final answer:
Proptosis and decreased ROM are the finding and symptoms that suggest orbital cellulitis.
Step-by-step explanation:

Proptosis refers to the forward displacement or bulging of the eye, which indicates swelling and inflammation within the eye socket. Decreased range of motion (ROM) suggests limited movement of the eye due to the swelling and inflammation.
