So little is understood concerning the pathogenesis of vernal conjunctivitis, and its treatment is so generally ineffective, that it occurred to the writer some months ago to address a circular letter to ophthalmic surgeons throughout the United States, with a view to ascertaining their experience in studying and treating this rare form of disease, and especially for the purpose of determining whether locality influenced the frequency of its occurrence or modified its clinical manifestations.
The paper which follows has, accordingly, been based in large measure on the answers which were received, together with a few personal observations which the writer has been enabled to make on a number of cases which have come under his own care.
