Cherry eye
From Freepedia
Cherry eye is the term used to refer to canine nictitans gland prolapse, a common eye condition in various dog breeds where the gland of the third eyelid prolapses and becomes visible. This condition usually must be corrected, mostly through surgery, because the gland produces some of the eye's tears. Older methods of cherry eye correction involved simply removing the gland, but it is a last-resort procedure today (complemented with a lifetime of eyedrops if performed), as the gland's purpose was unknown then. Modern methods of cherry eye correction involve repositioning of the gland to its normal location. The success rate of this type of surgery is approximately 80% in most breeds.
