A study of eighty-four cases of delayed mustard gas keratitis fitted with contact lenses

Abstract

Eighty-four cases of delayed mustard gas keratitis are reviewed. They were all fitted with contact lenses, some of them seven years ago. Thirty-nine of the patients wear their lenses from eight to sixteen hours a day, 11 from five to eight hours, eight under five hours, five not at all and in 21 cases the time is not known. The visual acuity in all but two was markedly improved. In twenty- five cases there was no further relapse after fitting, in four cases one relapse only, in 16 very slight relapses and in 10 only were the relapses severe. The tage of onset of the symptoms, the occupation of the patients and the treatment of intercurrent complications is discussed.
