Detection of connective tissue growth factor in human aqueous humor

Ophthalmic Res. 2002 Sep-Oct;34(5):306-8. doi: 10.1159/000065601.


Purpose: Connective tissue growth factor (CTGF) has been shown to be substantially involved in various processes of fibrosis. We investigated if CTGF is present in aqueous humor (AH).

Methods: Samples from AH were collected from 10 volunteers during cataract surgery. Specific ELISA analysis was performed with goat IGG against human CTGF.

Results: CTGF was above the detection limit of the assay in 80% of the samples. The concentration of CTGF in the anterior chamber fluid was 1.24 +/- (SD) 0.26 ng/ml.

Conclusion: CTGF is present in a majority of AH samples, possibly representing a constant component in this fluid. The origin and physiological importance of CTGF is yet unclear. The involvement of CTGF in processes of intraocular fibrosis and wound healing is possible.
