Interleukin (IL)-6, interleukin (IL)-8 levels and cellular composition of the vitreous humor in proliferative diabetic retinopathy, proliferative vitreoretinopathy, and traumatic proliferative vitreoretinopathy.

Purpose: To investigate the interleukin (IL)-6 levels, IL-8 levels, and cellular composition of the vitreous humor in patients with proliferative diabetic retinopathy (PDR), proliferative vitreoretinopathy (PVR), and traumatic PVR.

Methods: Vitreous samples from 14 patients with PDR, 10 patients with PVR, and 10 patients with traumatic PVR were analyzed. Fifteen cadaver eyes were used as controls.
