Does amiodarone affect eye sight?
Amiodarone has also been reported to cause optic neuropathy, which may result in permanent visual loss. The clinical presentation of amiodarone induced optic neuropathy may be similar to that of non-arteritic anterior ischaemic optic neuropathy (NAION).
Does amiodarone cause corneal Microdeposits?
Corneal microdeposits are seen in virtually all patients who receive amiodarone for more than 6 months. Corneal microdeposits result secondary to the secretion of amiodarone by the lacrimal gland with accumulation on, and absorption by, the corneal epithelium.
Does amiodarone cause retinal changes?
We presume that the use of systemic amiodarone may have predisposed our patient to retinal phototoxicity. It is possible that the mechanical disruption of the retina from the ERM also contributed to the susceptibility of the retina to the photosensitizing effect of amiodarone.

The whorl-like pattern which was firstly described by Fleischer in 1910 is characterized as powdery, white, yellow, or brown corneal opacities beneath the cornea apex.

Does amiodarone cause blindness?
Amiodarone ocular toxicity generally occurs within 1 year of drug initiation, with median time to onset of visual symptoms within 6 months. While the outcome of this toxicity is variable, permanent blindness in at least one eye has been reported for one-fifth of affected individuals.
What causes cloudy corneas?
Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina and may cause the cornea to appear white or clouded over. Common causes include Infection, injury, corneal abrasion or scratch or swelling of the eye.
Can amiodarone cause blindness?
Does amiodarone cause optic nerve damage?
Amiodarone optic neuropathy is characterized by insidious onset of visual loss, protracted disc edema (for months), and bilateral (usually simultaneous) involvement. In contrast, NAION is characterized by acute unilateral visual loss with resolution of disc edema over several weeks.
What are two adverse effects of amiodarone?
Can you fix a cloudy cornea?
Treatment may include patching the eye, using a temporary contact lens, and prescription eye drops or ointments. If vision problems remain or the cornea becomes permanently damaged, you may need a cornea transplant. This surgery removes the damaged cornea and replaces it with a healthy donor cornea.
