Corneal Endothelial Dysfunction as a Manifestation of Digoxin Toxicity

PURPOSE

The purpose of this study was to report a case of corneal endothelial dysfunction and subsequent corneal edema in a patient with digoxin toxicity.

METHOD

This was a case report.

RESULTS

A 77-year-old woman diagnosed with open-angle glaucoma and treated with a topical prostaglandin analog for 5 years developed blurred vision and photopsia in both eyes. Systemic medications included digoxin, furosemide, apixaban, amlodipine, enalapril, and simvastatin. Ocular examination revealed folds in Descemet membrane and corneal stromal edema in both eyes, with normal fundoscopy. Ancillary tests revealed elevated serum digoxin levels. No intervention other than discontinuation of digoxin was initiated. The corneal edema improved after that and resolved in the next 2 weeks.

CONCLUSIONS

We encountered 1 case of corneal edema secondary to corneal endothelial dysfunction in a patient with digoxin toxicity. Special care should be taken to elicit a complete history because ocular signs can be manifestations of systemic alterations with vital importance for patients.

Digoxin: Pharmacology and toxicology-A review

Digoxin is a cardiac glycoside used as drug in case of heart problems, including congestive heart failure, atrial fibrillation or flutter, and certain cardiac arrhythmias. It has a very narrow therapeutic window of the medication. Digoxin is toxic substance with well known cardiotoxic effect. In this work, pharmacology and toxicology of digoxin are summarized; Its pharmacokinetics, pharmacodynamics, available acute toxicity data (different species, different administration routes) are summarized in this article. Moreover, its treatment side effect and human poisonings are thoroughly discussed. Finally, appropriate therapy regimen is proposed.
