Detorakis ET, Grammenandi E, Pallikaris IG, Tsilimbaris MK - J Ophthalmol (2010)

Bottom Line: Results. dIOP was significantly higher in TG (5.19 mmHg) than in LG (4.01 mmHg) and CG (1.98 mmHg).Correlations between AL and dIOP were statistically significant in both TG and LG but not in CG whereas correlations between dIOP and other clinical parameters examined were statistically not significant in all groups.Conclusions.

ABSTRACT
Background. To evaluate differences between Goldmann Applanation Tonometry (GAT) and Dynamic Controur Tonometry (DCT) following trabeculectomy. Methods. Thirty eight glaucomatous eyes with a history of trabeculectomy (Trabeculectomy group, TG), 20 eyes without a history of trabeculectomy but with a history of latanoprost use (Latanoprost group, LG), and 19 nonglaucomatous eyes (Control group, CG) were included. GAT-IOP, DCT-IOP, the difference between them (dIOP), the central corneal thickness (CCT), the axial length (AL), and the depth of the anterior chamber (ACD) were measured. Results. dIOP was significantly higher in TG (5.19 mmHg) than in LG (4.01 mmHg) and CG (1.98 mmHg). Correlations between AL and dIOP were statistically significant in both TG and LG but not in CG whereas correlations between dIOP and other clinical parameters examined were statistically not significant in all groups. Conclusions. The significantly higher dIOP in TG implies that the bio-mechanical properties of the ocular walls are altered following trabeculectomy.

Mentions: Among TG patients, dIOP was also significantly higher in patients with a history of 2 procedures, compared with patients with a history of 1 procedure (independent samples t-test value 2.46, P =  .03). On the contrary, the correlation of dIOP with the postoperative interval from the last procedure was statistically not significant (Pearson's bivariate correlation coefficient). Correlations between dIOP and patients' age, CCT, or ACD were statistically not significant in all groups (Pearson's bivariate correlation coefficient). On the contrary, correlations between AL and dIOP were statistically significant in both TG (Pearson's bivariate correlation coefficient 0.31, P =  .01) and LG (Pearson's bivariate correlation coefficient 0.26, P =  .03) but not in CG. Scattergrams of the correlations between dIOP and AL in the TG, LG, and CG with respective trend lines, correlation coefficient values and p-values are presented in Figures 1(a), 1(b), and 1(c), respectively.
