Defining the seriousness of proliferative vitreoretinopathy by aspiration of cytokines from the anterior chamber.

AIM

Proliferative vitreoretinopathy is the major cause of retinal detachment surgery failure. Our prospective cohort study of 27 eyes aimed to determine intraocular levels of growth factors and cytokines in patients with retinal detachment with various degrees of severity of proliferative vitreoretinopathy using multiplex xMAP(®) Technology.

PATIENTS & METHODS: The concentrations of 12 proangiogenic, antiangiogenic, inflammatory and neurotrophic factors were measured from 0.05-ml samples of intraocular fluid using multiplex xMAP Technology. The results were compared with levels of various factors, which were measured in samples from the control group of 31 eyes prior to senile cataract surgery.

RESULTS

The concentration of the MCP-1 cytokine was found to be higher in eyes with retinal detachment compared with the control group. The concentration of VEGF was found to be higher in eyes with retinal detachment complicated with proliferative vitreoretinopathy compared with the uncomplicated retinal detachment group and the control group.

CONCLUSION

MCP-1 and VEGF may participate in pathogenesis of retinal detachment and proliferative vitreoretinopathy. Biomarkers in disease detection and management have become important tools in modern clinical medicine, and their application to retinal disease should be no exception.
