Presumed lipid retinopathy in a diabetic dog. 
An eight-year-old neutered male diabetic Cardigan Welsh Corgi was presented for bilateral mature cataracts.  Phacoemulsification and intraocular lens implantation were performed routinely, and recovery was uneventful for several months except for lipemic aqueous flare which gradually resolved during the postoperative period.  Five months following surgery the owner presented the dog for decreased vision.  White retinal deposits were visualized ophthalmoscopically.  Serum analysis revealed that the dog was concurrently markedly hyperlipemic.  The patient's diet was changed from a high- to a low-fat diet, following which diabetes control improved, hyperlipemia resolved, and the retinal deposits decreased markedly in size.  The retinal deposits seen ophthalmoscopically are presumed to be lipid based upon their association with marked hyperlipemia, and the concurrent resolution of hyperlipemia and the fundic lesions.
