The low-pressure mercury vapor lamp has unique and highly desirable features for corneal ultraviolet phototherapy. The emitted rays are highly germicidal,¹ virtually monochromatic at 2,537 A.,1 and totally absorbed by the cornea² with low keratitis effect.³ Previous work in corneal ultraviolet phototherapy utilized nonspecific polychromatic radiation which is less germicidal and more toxic than 2,537 A., but good results were still frequently obtained.^4,5 The corneal phototherapeutic use of the low-pressure mercury vapor lamp has not been previously reported in the literature. This paper will present: (1) the theoretical basis of corneal ultraviolet phototherapy and the advantages of using this lamp by comparing its only significant spectral radiation, 2,537 A., with the ideal phototherapeutic wavelength, and (2) a clinical and histological study of eyes irradiated by this lamp.
