What is your target volume when treating lymphoid hyperplasia of the lacrimal gland with radiation therapy?

Agree with treating the lacrimal gland only. For a symptomatic, polyclonal reactive lymphoid infiltrate unresponsive to less aggressive treatments, I think low-dose RT is reasonable. I would give 2 Gy X 2.

Good question! I believe, it is safe to treat the gland only. However, the ILROG guidelines suggest to treat the entire orbit.
