Koto, a sprite who is thought to be approximately 3 years of age, was adopted by me via a ferret rescue center. She had arrived at the center (4/18/94) pregnant and within hours successfully delivered her kits. Overall, Koto has enjoyed excellent health. Her diet has consisted of ANF Ferret Food (until that product was discontinued), 8 in 1, and most recently Totally Ferret. The first signs/symptoms of her visual problems became evident to me during the past two-weeks. While Koto has yet to walk into obstacles, I strongly suspect she has successfully done so by compensating with her other senses. During the first week she responded **inconsistently** to back-light objects moved rapidly and vertically two-feet away from her (I think she detected the movement by vision alone.) Her apparent ability to focus her eyes was also variable. At this time her pupils are unresponsive to a pen-light and based on functional observations, I question if Koto can see anything. The vet who examined Koto also wonders if Koto is blind. The diagnosis and cause have yet to be determined. At this time, an examination of the fundus is scheduled for next week. Meanwhile, the vet promised to seek-out information on the possible causes of visual loss/impairment (she doesn't think Koto is diabetic.) I in turn told her of the FML and that I would also request input. Your input regarding appropriate tests (bloodwork,etc.) will be most appreciated by the vet and me. Thank you in advance for helping us help Koto! Irene [Posted in FML issue 1329]
