Among the 57 cases of orbital lymphomas, 31 patients had a unilateral single lesion, 11 had unilateral multiple lesions, and 15 had bilateral multiple lesions.

The lesions were primarily located in the eyelids, orbits, conjunctiva, lacrimal glands, and inner canthus regions; among which 32 patients had lesions in the soft tissues of the eyelids, and the extraocular muscles were involved along the muscular cone space, developing into a cast shape, which was the most common.
