Archives:  Researchers describe a series of patients who demonstrate acute pigment dispersion with high IOP and iris transillumination defects, some flare but no cells in the anterior chamber, with heavy deposition of pigment in the TM.  The episodes were promptly relieved with topical steroids. Poor pupillary constriction is found later. The authors  could not point to any etiology. I am willing to bet that if they performed anterior chamber paracentesis, they will find some kind of virus. The authors speculate it may very well be related to another new syndrome, BADI (bilateral acute depigmentation of the iris). Yup- I would agree!
