Tinted contact lenses for treatment of retinal degeneration in a Greyhound.
The owner of a Greyhound reported photophobia and disturbance of vision in the dog's left eye. Racing performance, previously excellent, had become erratic under bright lighting. An irregular area of retinal degeneration was observed in the left eye. We used a flush-fitting scleral (haptic) lens made of tinted lucite with visible transmission of 9% to enhance rod function. Behavioral indications and racing performance improved after the fitting of this lens. The report describes a method of contact lens manufacturing, which will help veterinarians solve vision-related problems in domestic animals.
