Key result
Long-term amiodarone therapy was associated with intracellular inclusions, irregular stromal nerve fibers, and reduced anterior stromal keratocyte density compared to controls (p<0.001).
Why the study?
Does amiodarone therapy cause structural corneal changes detectable by in vivo confocal microscopy compared to healthy controls?
Case-Control (n=21)
Does amiodarone therapy cause structural corneal changes detectable by in vivo confocal microscopy compared to healthy controls?
p-value: p=<0.001
In vivo confocal microscopy reveals that amiodarone-induced keratopathy involves deeper corneal layers and greater structural toxicity than previously recognized, including reduced keratocyte density and nerve fiber irregularities.

May signal subclinical corneal toxicity on IVCM; leaves open visual impact and need for prospective studies.
Ciancaglini et al. (2001) conducted a case-control in Amiodarone-induced keratopathy (n=21). Amiodarone therapy vs. Healthy sex- and age-matched control subjects was evaluated on Corneal findings including keratocyte density and stromal nerve fiber appearance (p=<0.001). Long-term amiodarone therapy was associated with intracellular inclusions, irregular stromal nerve fibers, and reduced anterior stromal keratocyte density compared to controls (p<0.001).
