Active Transforming Growth Factor-beta2 in the Aqueous Humor of Posterior Polymorphous Corneal Dystrophy Patients

Abstract

Posterior polymorphous corneal dystrophy (PPCD) is characterized by abnormal proliferation of corneal endothelial cells. It was shown that TGF-beta2 present in aqueous humor (AH) could help maintaining the corneal endothelium in a G1-phase-arrest state. We wanted to determine whether the levels of this protein are changed in AH of PPCD patients. The level of active TGF-beta2 in the AH of all PPCD patients (mean +/- SD, 386.98 +/- 114.88 pg/ml) in comparison to the control group (260.95 +/- 112.43 pg/ml) was significantly higher (P = 0.0001). Compared to the control group, a significantly higher level of active TGF- beta2 was found in the PPCD1 (P = 0.0005) and PPCDx (P = 0.0022) groups. Levels of active TGF- beta2 were not significantly affected by gender, age, secondary glaucoma or by the progression of dystrophy when one or repeated PK were performed.
