Freebase

  1. Iris

    Iris is a genus of 260–300 species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, referring to the wide variety of flower colors found among the many species. As well as being the scientific name, iris is also very widely used as a common name for all Iris species, though some plants called thus belong to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. It is a popular garden flower. The often-segregated, monotypic genera Belamcanda, Hermodactylus, and Pardanthopsis are currently included in Iris.

Ophthalmologists who deal with people's eyes, Dr Homer concedes, have every right to be skeptical for the simple fact they are dealing with one of the most sensitive organs in the human body. Saj Khan, an ophthalmologist at the London Eye Hospital, told CNN the treatment raised some red flags. ' The main concern with any procedure that involves releasing pigment inside the eye is that the pigment can clog up the normal drainage channels which can in turn cause the pressure inside the eye to go up, if that happens significantly enough, for long enough, it's how patients develop glaucoma.
