    horseshoe tear, scleral indentation, retinal detachment
    This horseshoe tear was the cause of the detachment in this 54-year-old man. The orange area on the right half of the slide represents the area of scleral indentation. Please note that most of the tear lies over the indented area and appears orange. However, the extreme left side of the tear is brownish black in color because it is exactly superimposed over the dark shadow that always lies just beyond the indented area. The ability of scleral indentation to produce this color change combined with a sharp demarcation between the blackish area and the yellowish edge of intact retina is a pathognomonic sign of a full thickness retinal break.
