Question: 1 / 505

Which of the following is NOT a common antiseptic agent used around the eye?

Tincture of Iodine 2%

Hydrogen peroxide

Hydrogen peroxide is not commonly used as an antiseptic agent around the eye due to its strong oxidizing properties, which can cause significant irritation and damage to the delicate tissues surrounding the eye. The other agents listed—tincture of iodine, providine iodine (often known by the brand name Betadine), and alcohol—are more widely accepted for use in ocular procedures and for cleansing the skin around the eye.

Tincture of iodine and providine iodine are both effective against a wide range of pathogens and are often used prior to surgery or other procedures to disinfect the skin. Alcohol is also a common antiseptic, though it is less favorable for the immediate ocular environment due to its potential to cause stinging or discomfort. These characteristics contribute to the limited use of hydrogen peroxide in ocular applications, making it the least appropriate choice among the listed antiseptic agents.
