Reports concerning a white ring in the cornea have recently appeared in the literature. The original communication was made by Coats1 in 1912. Muramatsu,2 who also reported five new cases, recently reviewed the literature to date.
While this particular corneal lesion is not rare, it is seldom observed clinically because (1) there is so little subjective disturbance that the patient does not seek medical advice, and (2) the lesion is so tiny that it is probably often overlooked. Hence, little is known of the nature or development of this lesion.
The necessity of removing a foreign body from a cornea in which a typical white ring was present adjacent to the foreign body afforded the opportunity of removing a portion of the white ring at the same time.
