The Ocular Application of Povidone-Iodine

Sherwin J Isenberg, MD Leonard Apt MD

Community Eye Health. 2003; 16(46): 30–31.

 

"Why was povidone-iodine chosen as an antimicrobial agent?

  • In the appropriate concentration, it is not toxic to the eye as are other iodine bearing compounds
     

  • It has a very broad antimicrobial spectrum, including bacteria, viruses, and fungi, given enough contact time in vitro
     

  • Resistance by bacteria is rare
     

  • The medication turns the eye brown for a few minutes proving that it has been applied
     

  • It is widely available as a solution or powder; and so it is available throughout the world in some form
     

  • Finally, especially important for use in developing areas, it is not expensive."

"In summary, povidone-iodine ophthalmic solution has been proven effective before (5% solution) and after ocular surgery (1.25%), at birth (2.5%), and for some forms of conjunctivitis (1.25%). Investigations of its use in treating other types of ophthalmic infections are continuing. The use of povidone-iodine in ophthalmic practice continues to reduce the incidence of blindness in children and adults throughout the world."
