IgG4-related ophthalmic disease (IgG4-ROD) is the recommended term to describe orbital (eye socket) manifestations of the systemic condition IgG4-related disease,[2] which is characterised by infiltration of lymphocytes and plasma cells and subsequent fibrosis in involved structures. It can involve one or more of the orbital structures.

Frequently involved structures include the lacrimal glands, extraocular muscles, infraorbital nerve, supraorbital nerve and eyelids.[3][4][5][6][7][8] It has also been speculated that ligneous conjunctivitis may be a manifestation of IgG4-related disease (IgG4-RD).[9]

As is the case with other manifestations of IgG4-related disease, a prompt response to steroid therapy is a characteristic feature of IgG4-ROD in most cases, unless significant fibrosis has already occurred.[2][3]

It basically can cause loss of vision and in other cases, cause skin irritation and loss of brain function
