The hyporhyroidism pattern of cornea verticillata results from the centripetal migration of deposit-laden limbal stem cells as the corneal epithelium undergoes natural growth and repair. In the amiodarone-induced keratopathy, the highly reflective epithelial cells were first found at the center of the cornea and then spread to the periphery with increasing time on amiodarone. Although the limbal epithelial cells were not positive in the amiodarone-induced keratopathy, they were similar in appearance by IVCM and slit-lamp biomicroscopy at the peripheral to the central cornea.

Thus, foraminifera tests for hypothyroidism highly reflective epithelial cells detected by IVCM may indicate the presence of vorte of amiodarone or Gb3 in the lysosomes of the epithelial cells in these two keratopathies. Curr Opin Ophthalmol. Kook, C. Previous reports and our results showed that it requires about 1 to 3 months to detect amiodarone keratopathy [ 111314 ] indicating that it may take time for the endocytosed amiodarone to be detected by IVCM as the highly reflective material by the corneal epithelial cells. Amiodarone has high affinity for lipids in the cells especially in the lysosomes, and their interactions result in the accumulation of intracytoplasmic lamellar inclusion bodies. There are some limitations in our study.

Corneal verticillata is recognizable as fine golden-brown or vortec opacities in the basal epithelium that branch out from a central whorl, usually across the inferior cornea. The deposits lead to various side effects, for example, hypohidrosis, cardiomyopathy, renal failure, and vortex keratopathy [ 23 ].

There are also less common ocular findings in Fabry disease including cataracts and conjunctival and retinal vessel tortuosity [ 367 ]. Special pages. It is generally accepted that the corneal epithelial stem cells are in the basal epithelial layer at the limbus, and they differentiate and migrate centripetally across the cornea to the central area [ 23 — 26 ].

First, fabrry limited resolution of the model of IVCM used did not allow us to differentiate the cytoplasmic changes in the two diseases in more detail. Thus, it was established that the hyperreflective deposits were in the corneal epithelial cells in both Fabry diseases and amiodarone-induced keratopathy. Main page.

Original article contributed by :. Kaplan and W. In Fabry disease, globotriaosylceramide deposits are taken up by the lysosomes of the limbal epithelial stem cells, and they differentiate and migrate to the center of the cornea to form the whorl pattern. In contrast, highly reflective epithelial cells were consistently observed to be present at the limbus to the central cornea in Fabry disease. Special Issues.
Thus, the purpose of this study was to compare the morphological appearance and time course amiofarone the development of the cornea keratopathy in amiodarone-induced keratopathy to that in Fabry disease.

It may also be possible that different doses of amiodarone or different enzyme levels in Fabry disease might affect the cytoplasmic deposits which are the cause of the high reflectivity of the cytoplasm.
