Inflammatory molecules in aqueous humour and on ocular surface and glaucoma surgery outcome.

Cvenkel B, Kopitar AN, Ihan A - Mediators Inflamm. (2010)

Bottom Line: Thirty patients who needed antiglaucomatous surgery were included.Eyes with trabeculectomy failure at 3 months showed significantly higher TNF-alpha and IL-6 levels in the aqueous than eyes with successful surgery.Increased expression of HLA-DR on epithelial cells and antigen-presenting cells was not associated with the trabeculectomy outcome.

ABSTRACT

Purpose: To investigate the influence of inflammatory molecules in the aqueous humour and on the ocular surface on the outcome of glaucoma surgery.

Methods: Thirty patients who needed antiglaucomatous surgery were included. The interleukin- (IL-) 8, IL-1beta, IL-6, IL-10, tumour necrosis factor- (TNF-) alpha; and IL-12 were determined from aqueous humour preoperatively and the imprints of conjunctiva were analysed for expression of human leukocyte antigen- (HLA-)-DR after surgery by flow cytometry. The success of trabeculectomy was defined as intraocular pressure less than 21 mmHg without antiglaucoma medication.

Results: Eyes with trabeculectomy failure at 3 months showed significantly higher TNF-alpha and IL-6 levels in the aqueous than eyes with successful surgery. Increased expression of HLA-DR on epithelial cells and antigen-presenting cells was not associated with the trabeculectomy outcome.

Conclusions: Higher preoperative levels of TNF-alpha and IL-6 in aqueous humour may contribute to the development of inflammatory milieu and were associated with worse outcome of glaucoma surgery.

fig5: Box plot of expression of HLA-DR on conjunctival epithelial cells 1 month and 3 months after surgery in eyes with successful and failed trabeculectomy (P = .001).

Mentions: The expression of HLA-DR on epithelial cells was significantly lower 3 months compared to 1 month after surgery (paired sample t-test; P = .001), both for the eyes with surgical success and failure (Figure 5). There was no significant difference in the percentage of HLA-DR positive epithelial and antigen-presenting cells as well as in the expression of HLA-DR by antigen-presenting cells between 1 month and 3 months of follow-up (not shown).
