Excessive use of garlic may produce a unique and irritating odor. A study published in the 2007 issue of Molecular Nutrition and Food Research said that although garlic has many potential health benefits, excessive garlic can interfere with blood clotting. If you have taken prescription blood thinners such as warfarin, garlic will increase its effectiveness and increase the likelihood of excessive bleeding. In some cases, large amounts of garlic can cause or aggravate eye bleeding, leading to decreased vision. Please consult a doctor before taking garlic supplements.

Garlic can interfere with platelets, the ability to accumulate small fragments in the area of vascular injury, to stick together. Drugs with this effect are often referred to as blood thinners, although garlic does not dilute the blood, but acts as an anticoagulant. Anticoagulants prevent blood from clotting, which can lead to excessive bleeding after spontaneous or injury.
Anterior chamber
Anterior chamber hemorrhage refers to intraocular anterior chamber hemorrhage, including gaps. Iris - the colored part of the eye - and the cornea - a thin, dome-shaped tissue covering the front of the eye. If you have eye trauma, such as a blow, anterior chamber hemorrhage may occur. Cancers infected with the eyes or eyes can also cause anterior chamber bleeding. Taking large doses of anticoagulants such as garlic can cause anterior chamber bleeding or worsening anterior chamber bleeding for other reasons. Because your blood can't condense properly, it continues to flow into the anterior chamber. Hyphema can cause vision loss, which can become permanent.
Retinal Diseases
Many people take prescription anticoagulants to prevent stroke or heart disease. Two diseases, diabetic retinopathy and macular degeneration, usually cause intraocular hemorrhage due to the formation of abnormal blood vessels. Dr. Randall Wong, an ophthalmologist and retina specialist in Virginia, pointed out that taking blood-dilution drugs may not increase vision loss.
Diabetic retinopathy and macular degeneration can cause retinal vascular leakage, the cell's photoactive layer at the back of the eye. Bleeding can also occur in the vitreous of the central portion of the eye that is filled with fluid. This will block lightEntering the eye causes temporary but often reversible vision loss. If you have diabetic retinopathy or macular degeneration, ask your ophthalmologist if you can safely take garlic - over-the-counter supplements rather than prescription drugs.
Subconjunctival hemorrhage
All eye bleeding can cause vision loss. For example, subconjunctival hemorrhage causes the sclera (the white part of the eye) to turn bright red; according to All About Vision, this looks terrible, but usually does not affect vision. Taking anticoagulants such as garlic can cause or worsen subconjunctival hemorrhage, which occurs when the conjunctival vascular ruptures, but this is usually done within 7 to 10 days without any loss of vision.
