Purpose.
To investigate the differences in axial length, corneal curvature, and corneal astigmatism with age in patients with Marfan syndrome (MFS) and ectopia lentis.
Methods.
A retrospective case series study was conducted.
MFS patients with ectopia lentis were divided into groups according to age.
Axial length, corneal curvature, and corneal astigmatism were measured.
Results.
This study included 114 MFS patients (215 eyes) with a mean age of 19.0 ± 13.9 years.
Axial length differed significantly across age groups in MFS patients (P<0.001), whereas corneal curvature did not (P=0.767).
Corneal astigmatism was statistically significant throughout the MFS cohort (P=0.009), but no significant difference was found in young MFS patients (P=0.838).
With increasing age, the orientation of the corneal astigmatism changed from with-the-rule astigmatism to against-the-rule or oblique astigmatism (P<0.001).
A linear correlation analysis showed weak correlations between age and axial length for both eyes and with corneal astigmatism for the left eye, but there was no correlation between age and corneal curvature.
Conclusions.
In MFS, axial length varies with age, corneal curvature remains stable, and corneal astigmatism is higher in young patients and tends to shift toward against-the-rule or oblique astigmatism.
Therefore, it is important to consider age when diagnosing MFS with ocular biometric data.
