Amiodarone keratopathy and lens opacities
Summary
Amiodarone hydrochloride, an antiarrhythmic medication, commonly causes corneal deposits and anterior lens opacities in patients. These eye conditions often resolve after discontinuing the drug.
Area of Science:
- Ophthalmology
- Cardiology
- Pharmacology
Background:
- Amiodarone hydrochloride is a widely used antiarrhythmic drug.
- Ocular side effects, including keratopathy and lens opacities, are known but often asymptomatic.
- Understanding the prevalence and resolution of these ocular findings is crucial for patient management.
Purpose of the Study:
- To investigate the incidence and characteristics of ocular side effects in patients treated with amiodarone hydrochloride.
- To observe the resolution of these eye findings after drug discontinuation.
Main Methods:
- Serial ophthalmological examinations were conducted on 21 patients receiving daily amiodarone hydrochloride (200-600 mg).
- Observation periods ranged from six months to three years.
- Corneal and lens findings were documented, and resolution was monitored post-discontinuation.
Main Results:
- All 21 patients developed corneal deposits (keratopathy).
- Anterior subcapsular lens opacities were observed in 12 out of 20 phakic patients.
- Keratopathy resolved in three patients during follow-up periods of 7 to 20 months after stopping amiodarone.
Conclusions:
- Amiodarone hydrochloride consistently induces keratopathy and frequently causes anterior lens opacities.
- These ocular side effects are generally asymptomatic.
- Ocular findings, particularly keratopathy, may resolve after amiodarone hydrochloride discontinuation.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Antiarrhythmic Drugs: Class I Agents as Sodium Channel Blockers
Class I antiarrhythmic drugs are used to treat various types of arrhythmias or irregular heart rhythms. These drugs block the sodium (Na+) channels in the cardiac cells, thereby affecting the movement of electrical impulses across the heart. Class I antiarrhythmic drugs are divided into three subgroups: Class IA, Class IB, and Class IC, each with distinct mechanisms of action and effects on the heart.
Class 1A Antiarrhythmic Drugs: These drugs work by moderately blocking sodium channels,...

Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of the heart's...
Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
