Corneal Topography Findings Among Patients With Thyroid Dysfunction

The aim of this study is to study  the topographic corneal changes in patients with thyroid dysfunction.

This is cross sectional study of 200 thyroid patients attending thyroid clinic at faculty of medicine Alexandria University. The Corneal topography of subjects were examined with TMS (Tommey GmbH., Japan).

Two hundred patients with thyroid dysfunction were enrolled in the study. Mean age was 32.4 ± 8.2 years (range: 17 to 45) years of them 63 were malees and 137 were females..Keratometric readings K1, K2, and Kmax readings were recorded for each patient. Showing mean k1 45.86 ± 4.69 diopters  mean  k2 47.89 ± 5.08diopters

and mean corneal thickness of 475 ± 0.36 microns .no orelation was found between any of these parameters and serum T3,T4 or TSH

more topographic changes in favor of thin cornea and steep cornea rather than a true keratoconus were detected in patients with thyroid dysfunction making cautious analysis of corneal topography is important especially before refractive surgery
