Cataracts are a progressive change to the lens of the eye, resulting in cloudiness and interference with vision. Cataracts are the most common cause of blindness in dogs. Surgical removal of the lens, and placement of an intraocular lens implant can restore normal vision. Although every effort is made to remove as much lens material as possible during cataract surgery, it is inevitable that some lens cells remain. These cells will migrate and proliferate, resulting in the most common complication to cataract removal: posterior capsule opacification (PCO), where a new layer of cells on the back of the lens capsule interferes with light transmission and results in secondary vision loss. Cataracts occur in all breeds and PCO occurs in up to 100% of canine post-operative cataract patients. Unfortunately, there is no consistently effective treatment for canine PCO.

The lecture focused on the newer developments of novel therapies to reduce PCO formation including surgical and pharmaceutical interventions. This lecture also discussed potential intraocular [into eye] drug delivery options to prevent PCO. At this time Dr. Chandler is researching whether the drug Cyclosporin A (CsA), can decrease PCO formation and decrease post-operative inflammation. Her goal is to determine whether CsA can provide a safe and reliable option to prevent PCO in dogs.

Dr. Chandler’s research primarily focuses on cataract formation and complications associated with them. She has been faculty in the College of Optometry and adjunct faculty in the College of Veterinary Medicine since 2007.
