Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Congenital glaucoma with sirsasana yoga posture

    The sirsasana (stand-on-hand posture) was a problem for a patient with congenital glaucoma who had practiced this yoga posture for several years.

    First, the details.

    • Ophthalmic examination included a battery of tests including intraocular pressure before, during, and after maintaining the sirsasana posture for 5 minutes.

    And, the results.

    • Intraocular pressure increased significantly during the sirsasana posture.

    The bottom line?
    The authors warn, “Transient elevation in intraocular pressure during yoga exercises may lead to progressive glaucomatous optic neuropathy, especially in susceptible patients with congenital glaucoma.”

    In another case report, increased intraocular pressure was also associated with sirsasana.

    More specifically, in a study of 75 people from a yoga training institute, there was a “uniform 2-fold increase in the intraocular pressure during sirsasana, which was maintained during the posture in all age groups irrespective of the ocular biometry and ultrasound pachymetry.”
