The recent literature describes two new lesions of the sclera—one primarily necrotic in origin and the other primarily degenerative in character. Within a period of six months I have observed 5 cases of the latter type. The condition is one of symmetric hyaline degeneration of the sclera, occurring in advanced age and characterized by the presence of slate gray plaques, situated about 3 mm. from the limbus and 1.5 to 2 mm. anterior to the insertions of the rectus muscles, to which they bear a definite relationship. Clinically, these hyaline areas probably escape notice because the patient rarely draws the physician's attention to their presence. I believe that they would be found much more frequently if ophthalmologists paid more attention to such conditions during their routine clinical examinations. It is surprising that so few contributions to the literature on the subject have been made. REVIEW OF LITERATURE I have made
