Fleck (Mouchetée) dystrophy of the cornea.
Five families, four Caucasian and one Negro (14 patients) with fleck (speckled or Mouchetée) dystrophy of the cornea are presented. In each, the typical presentation of fine scattered fleck-like dystrophic lesions was found throughout all layers of the central and peripheral corneal stroma but not affecting the epithelium, Bowman's membrane, Descemet's membrane or the endothelium. Clear stroma was noted between each lesion. Visual acuity in all patients was normal or only slightly affected. Except for an occasional patient with minor photophobia, almost all patients found affected with this dystrophy were asymptomatic in regard to their corneal condition. There was no decrease in corneal sensitivity noted in any patient. All families displayed evidence of an autosomal dominant hereditary pattern and progression of the dystrophy is slow and benign in character.  With the exception of one family with atopic disease, no systemic organic illness was noted by histroy in all of the families. Laboratory screening of 2 of the 5 families showed no abnormalities of any systemic metabolic disorders. The characteristic clinical picture and favorable prognosis of this condition enables one to easily differentiate this condition from other known parenchymatous corneal dystrophies. The incidence of this condition is probably much more common than the reported cases in the literature might indicate.
