What is optical cellulitus and how is it treated?

Makesno sense: The question mixes many different possibilities and needs to be rephrased more focused yo give an appropriate answer.

Orbital cellulitis: I think you mean orbital cellulitis, an infection of the orbital tissue surrounding the eye. This causes pain, limitation of eye motion and can severely damage the tissues and eventually the vision. Usually it is infectious and requires systemic antibiiotics. It may require a hospital admission. Rarely it is associated with tumors and other periocular pathology.
