Table 4. GSH/GSSG ratio in orbital fibroblasts before and after treatment with 200 μM H₂O₂.

Redox status	Basal treatment (mean±SD)	After treatment (mean±SD)	Induction ratio (%)* (mean±SD)	p -value
GSH/GSSG ratio
Normal	84.00±15.21	65.60±6.68	78.94±8.45	0.094
GO	43.15±6.10	21.58±3.58	50.75±10.86	0.008

*Induction ratio=GSH/GSSG value after H₂O₂ treatment/baseline value (%).
