The Role of Symptom Duration and Serologic Factors in the Relapse of IgG4-Related Ophthalmic Disease following Surgery: A Retrospective Cohort Study

Table 3

Baseline serological test in the short- and long-symptom-duration groups.

Variables	Short symptom duration	Long symptom duration	value
Serum IgG (g/L)			0.030
Serum IgG4 (g/L)			0.417
Serum IgG4/IgG (%)			0.972
Serum IgM (g/L)			0.536
Serum IgE (IU/mL)			0.011
Serum IgA (g/L)			0.724
Serum eosinophilia (×10^9/L)			0.004

Normal ranges: IgG 7-16 g/L; IgG4 <1.35 g/L; IgM 0.5-2.5 g/L; IgE <165 IU/mL; IgA 0.85-3 g/L; eosinophilia 0.02-0.52 (×10⁹/L).
