TREATMENT OF OCULAR INFECTION* Since the introduction of sulfonamides and antibiotics the frequency of visual dam age resulting from superficial infections of the eye has been much reduced. This is per haps most clearly evident from the gratify ing response to treatment of hypopyon ulcer. Sensitivity of the infecting organism is usu ally readily apparent from reduction of the ocular injection; and, in corneal lesions especially, this is often a more useful guide to progress than bactériologie examination. Suppression of the inflammatory reaction by topical application of steroid preparations may produce whitening of the eye similar to that seen during recovery, and in certain cases—for example, interstitial keratitis, where the reaction occurs from an allergic type of response in the absence of corneal organisms—this may be entirely beneficial. Where active infection exists, however, such whitening is often deceptive: the infection, although apparently ameliorated, pursues a protracted course, deeper invasion of the ocular tissues is encouraged and serious complications are not unusual. Such sequelae have been recognized as hazards of steroid therapy since the earliest trials of topical cortisone in this country, and it is remarkable that they continue to be seen in apparently undiminishing num bers. They result more commonly from the use of preparations of a steroid combined with an antibiotic or sulfonamide, than from the use of steroids alone. A further reminder of this peril comes from the United States, in respect to mycotic infections. Gingrich* re ports 10 cases of mycotic corneal ulcer in which the fungi were identified either from the conjunctival discharge or from corneal scrapings. In most of these cases there were deep ulcers, and four of these perforated into the anterior chamber. Descemetoceles »Reprinted from The Lancet, July 21, 1962, pages 137 and 138. t Gingrich, W. D.: J.A.M.A., 179:602, 1962.
were seen in a further three, and in four there was hypopyon ; in two, secondary cata racts developed, and in all but two (which were detected in an early stage) the visual effects were severe. Seven of these cases had previously been treated with preparations containing steroids, some of them for weeks, and this treatment is thought by Gingrich to have contributed materially to the ultimate damage resulting from the infection. In all but two cases minor trauma had also oc curred; and thus the steroid, through its known effect of discouraging corneal epi thelial healing, had played a further part in the disastrous course of the condition. Of the many species of saprophytic fungi which have been identified as causes of keratomycosis, only seven were encountered in this series. Gingrich recommends a form of combined sulfacetamide-thimersal therapy applied by iontophoresis, as generally the the most effective where a fungus is the in fecting organism. Specific antimycotic treat ment will no doubt in time be devised; but it is greatly to be hoped that, meanwhile, the advocacy of preparations of steroid com bined with antibiotic or sulfonamide will be curtailed, and the use of steroids avoided where the corneal epithelium is not known to be intact.
