Corneal Tomographic Parameters in TGD

NCT04433936 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 100

No results posted yet for this study

Summary

The current study involved analysis of the corneal tomographic parameters of patients with thyroid gland dysfunction (hyperthyroidism or hypothyroidism), including those with an autoimmune etiology, in comparison to healthy controls without TGD, using pentacam, in an attempt to detect possible early corneal changes and to highlight whether early screening of those patients would be necessary for early detection of KC.

Conditions

  • Keratoconus
  • Corneal Ectasia
  • Thyroid Eye Disease

Interventions

DIAGNOSTIC_TEST

Pentacam tomography

The Pentacam maps were analyzed. The following anterior and posterior corneal surface parameters were evaluated by the Scheimpflug system: Kf, Ks, Kmax. The pachymetric map was analyzed, including CCT at the apex of the geometric center and CTmin. PPIavg, PPI min and PPI max were calculated . The Ambrósio relational thickness (ART) was calculated The posterior corneal elevation maps were evaluated and the posterior corneal elevation values relative to this reference were recorded. The back difference elevation and multimetric D index values were extrapolated from the difference map of the Belin/Ambrósio-enhanced ectasia display of the Pentacam system.
