title: Gyrate atrophy of the choroid: two cases.
abstract: BACKGROUND
  Gyrate atrophy of the choroid (GA) is a rare, inherited choroidal dystrophy that results in progressive deterioration in peripheral and night vision. This is the first documentation of GA in Singapore.
  
  
  METHODS
  This report illustrates 2 cases of a sibling pair from a consanguineous union, presenting with the classical clinical features and biochemical abnormality of this condition.
  
  
  RESULTS
  One patient was treated with pyridoxine replacement and a low protein diet. However, his condition failed to improve. The other patient was left untreated.
  
  
  CONCLUSIONS
  Treatment was ineffective for the first patient. As yet, there is no proven treatment of GA.
