[Thygeson's superficial punctate keratitis (author's transl)].

Ten cases of Thygeson's bilateral punctate epithelial keratitis were observed during a two year period. The diagnosis, therapy and prognosis are discussed. The common erroneous diagnosis of herpetic keratitis may lead to corneal damage as a result of too intensive therapy. Highly hydrophilic contact lenses have proven to be a valuable aternative to steroid therapy. The etiology remains obscure. Viruses were not detected with either tissue culture technique or with electron microscopy.
