Description
Dogs with sudden acquired retinal degeneration go blind quickly when their light-sensing cells fail, yet some pupil responses survive. Soohyun Kim and six co-authors followed fifteen affected dogs and nine healthy controls for a year, testing pupil reactions to red, white, and blue light and measuring retinal thickness with scans. Donated eyes were examined under the microscope.
Affected dogs already showed weaker, slower pupil responses to red light and weaker responses to white light, while blue-light responses matched the controls. White-light speed declined further over the year. Scans showed the whole retina thinning while the inner layers held steady, and tissue confirmed outer-layer loss with inner layers preserved. The pattern fits the survival of special ganglion cells that sense light themselves, and the authors recommend pairing both tests to track the disease.
