Rate of ophthalmic symptoms and affected ocular anatomic structures in IgG4-ROD patients. a Proportions of patients with different ophthalmic symptoms in IgG4-ROD patients. The most frequent ophthalmic symptom was eyelid swelling (74.1%), followed by xeropthalmia (49.4%) and proptosis (12.2%), while decrease vision (2.7%) was relatively rare. b Proportions of patients with different ocular anatomic structures involved in IgG4-ROD patients. The lacrimal gland (98.4%) occupied the most frequently affected ocular anatomic structure, followed by the extraocular muscle (8.2%), while the eyelid (3.9%), soft tissue (3.1%), conjunctiva (1.2%), trigeminal nerve (1.2%), orbital bone (1.2%), sclera (0.4%), and optic nerve (0.4%) were relatively rare.
