Abstract

Purpose : To evaluate corneal air-puff deformation responses as predictor of disease status and progression in Marfan Syndrome (MFS).

Methods : This prospective observational clinical study monitored right eyes of 44 individuals (19 female, 25 male; mean age 42±12) diagnosed with MFS. The revised Ghent criteria, with particular attention being paid to the degree of aortic root dilatation (Z-Score) as correlates of disease status, were correlated with ocular biometry, corneal topography, tomography (Pentacam [Oculus]; Galilei G6 [Ziemer]) and dynamic Scheimpflug-based biomechanical analyses (CorvisST [CST; Oculus]). These findings were compared to 30 control subjects. A t-test or Wilcoxon matched-pairs test were used to test for statistically significant differences between these groups. Our study was approved by the local Ethics Committee Hamburg.

Results : Comparing control- and MFS-eyes, the corneal biomechanical parameters A1 length, A2 length, radius of the inward-bended cornea, and deflection length at the highest concavity revealed statistically significant differences (P<0.05). In addition, the comparison between low- and high-risk patients demonstrated consistently increasing differences with increasing statistical significance between mild and those with advance MFS stages.

Conclusions : In vivo noninvasive biomechanical analyses (CST) offer a new reliable method to describe and distinct
features of corneal deformation responses between low- and high-risk patients with MFS. In the future corneal air-puff deformation responses might therefore be used in early identification of critically ill patients at high risk of disease progression as an adjunct to existing diagnostic tests.
