Introduction:

IgG4-related ophthalmic disease (IgG4-ROD) presents a frequency of 11-58.8%. Few studies describe the disparities with patients with extraophthalmic IgG4-related disease (NOT IgG4-ROD).

Objectives:

describe the clinical, imaging, pathological characteristics, laboratory results, and treatment of IgG4-ROD characteristics; and compare them with those of the NOT IgG4-ROD patients.

Materials and methods:

a descriptive study was carried out on a cohort of 54 patients with ER-IgG4. 16 patients with IgG4-ROD and 38 with NOT IgG4-ROD were recruited. The data was analyzed with the SPSS Statistics 19 software.

Results:

IgG4-ROD predominated in women. 75% presented bilateral ophthalmic involvement. A history of asthma was associated with the NOT IgG4-ROD group (p=0,018). Patients with IgG4-ROD presented lower serum levels of IgE and total IgG, and the lacrimal gland was the most affected structure. Lymphoplasmacytic and eosinophilic infiltrates predominated, with storiform fibrosis being more frequent than non-storiform in the IgG4-ROD group.

Conclusions:

although the results were similar to those previously reported, in disagreement with other series, we found a negative association between asthma and serum total IgG levels with EOR-IgG4 patients.
