• The University of Missouri-Columbia is collecting DNA samples for identification of genetic markers for glaucoma.  It was announced in September, 2009 that Drs. Gary Johnson and Elizabeth Guiliano at MO, along with researchers from the Animal Health Trust in England, have discovered a mutation for primary lens luxation.  These two research groups are collaborating in sharing data and publishing results.  Glaucoma and PLL are studied together because PLL can cause secondary glaucoma, and conversely, primary glaucoma can cause a secondary lens luxation.  Thus, it is not always clear which condition is primary.  Information about this research can be found at http://www.caninegeneticdiseases.net/ under primary lens luxation.

  • If you have a dog that develops glaucoma, please consider submitting blood samples from the dog and its relatives to these studies.
