title: [Familial juvenile macular dystrophy with congenital hypotrichosis capitis].
abstract: BACKGROUND
  Our knowledge about the pathogenesis of hereditary macular diseases is still very circumscript. For genetic determination, a knowledge of the coincidence of eye symptoms and other defined common symptoms is helpful. The purpose of this paper was to present two sisters of a family of consanguineous parents with the combination of hypotrichosis of the head and macular dystrophy in the context of a tricho-ocular malformation of an ectodermal dysplasia. A review of the recent literature is included.
  
  
  METHODS
  Two 13- and 17-year-old sisters presented at our hospital with reduced visual acuity because of symmetrical central changes of the retinal pigment epithelium and chorioatrophic scars according to macular dystrophy combined with hypotrichosis capitis. We performed fundus perimetry and histological examinations of the hair.
  
  
  RESULTS
  The 13-year-old patient exhibited central changes of the retinal pigment epithelium leading to a relative central scotoma for Goldmann 1/4 during fundus perimetry in both eyes (visual acuity 0.125 and 0.4). We found central chorioatrophic scars, followed by absolute central scotomas, with unstable fixation in the upper retinal hemisphere in her 17-year-old sister with reduced visual acuity (0.16 and 0.2).
  
  
  CONCLUSIONS
  There are few descriptions of the association of macular dystrophy and hypotrichosis. The combination of hypotrichosis and macular dystrophy could make genetical analysis easier. Mutational analysis of the TIMP-3 gene that has previously been associated with Sorsby fundus dystrophy did not reveal any disease-causing mutations in our patients.
