This study aimed to evaluate systemic levels of pCRP, mCRP, interleukin-6 (IL-6), and interleukin-1β (IL-1β) in patients with a variety of intraocular inflammatory conditions, including diabetic macular edema (DME) and non-infectious uveitis such as Behçet’s disease (BD), Birdshot retinochoroidopathy (BSRC), HLA-B27-associated uveitis, and undifferentiated uveitis (UU).
