Orbital floor fracture - worried about Enophthalmos. What are the chances?

I got punched just above the eye and suffered an orbital floor fracture. The fracture is about 13mm long at the worst point however it's not displaced by much at all maybe 1-2mm Max. The eye itself is completely fine after being checked and swelling has healed after 2 weeks. Infra orbital nerve function has almost completely returned after 2 weeks. Doctors at the hospital opted to monitor instead of operate. How high are the chances of Enophthalmos? And if this happens can it be easily corrected?
