[Raise awareness of IgG4 relative ocular disease]

Purpose IgG4-related ocular disease is a chronic systemic disease with lymphocyte abnormal. The lacrimal glands, extraocular muscles and infraorbital nerve were often involved which was often the first symptom of systemic disease. While ophthalmologists did not know this disease well. They usually misdiagnosed it as idiopathic inflammatory pseudotumor, thyroid-associated ophthalmopathy etc, which resulted in delayed treatments. Here pathogenesis, clinical features and treatment methods of IgG4-relative ocular disease were described in order to improve awareness of this ocular disease, reduce clinical misdiagnosis, improve disease prognosis and standardized treatment. As the incidence of this disease increased in recent years, it is very necessary to improve awareness of the disease for ophthalmologists.
