[Dimmer's keratitis nummularis, a doubtful disease].
From Dimmer's original description of 4 cases of keratitis, it would seem that what is now known as a keratitis nummularis (Dimmer), is not one specific corneal disease but a heterogeneous group of diseases. Salzmann demonstrated in certain cases a clear relationship between it and herpetic keratitis and its corneal complications. Later authors have not convincingly differentiated KND from herpetic keratitis, as no tests have been performed to determine corneal sensitivity. Pillat, who did use the criterion of normality of corneal sensitivity for the diagnosis of KND, was unable to differentiate KND adequately from the sequelae of adenovirus keratitis. Nummular keratitis (Dimmer) does not play a diagnostic part in ophthalmology, as we are not dealing with a nosological entity.
