Purpose: To report a case of IgG4-related ophthalmic disease, which presented with papillitis and subretinal deposits.
Methods: Observational case report with multimodal imaging.
Results: A 52-year-old man with a history of persistent lymphadenopathy presented with decreased vision in his left eye. Funduscopic examination demonstrated cuticular drusen in both eyes and florid edema of the left optic nerve, along with scattered circumscribed grey-yellow subretinal deposits that were distinct from the cuticular drusen. Swept-source optical coherence tomography demonstrated a hyper-reflective subretinal material corresponding to the grey-yellow subretinal deposits on clinical examination along with diffuse outer retinal disruption. Fundus autofluorescence revealed scattered hypoautofluorescence corresponding to cuticular drusen and also larger patches of hypoautofluorescence corresponding to the grey-yellow subretinal deposits. Fluorescein angiography demonstrated hypofluorescence corresponding to the large subretinal deposits and leakage at the optic nerve. Lymph node biopsy demonstrated IgG4-positive plasma cells and elevated serum IgG4 levels leading to a diagnosis of IgG4-related ophthalmic disease. The patient was treated with oral prednisone with subsequent resolution of the optic nerve edema.
Conclusion: We describe multimodal imaging of unique retinal and optic nerve findings associated with IgG4-related ophthalmic disease. Our report broadens the spectrum of ocular involvement associated with IgG4-related disease.
