title: [Goldmann-Witmer, definitive diagnosis in unifocal helicoid choroiditis].
abstract: METHODS
  A 20 year-old healthy patient consulted due to acute loss vision in his left eye. A fundus examination showed a macular alteration compatible with unifocal helioid choroiditis, characterized by being an atypical inflammatory yellow-white, round, single lesion of approximately an optic disc in diameter. The etiology study detected low Antitoxoplasma gondii Ig G (immunoglobulin) titers.
  
  
  CONCLUSIONS
  The non-specificity of the serology and the atypical characteristics of the lesion is a limitation in the diagnosis. The Goldmann-Witmer coefficient may be useful in the diagnosis of atypical lesions, by comparing the concentration of IgG from the serum and aqueous humor.
