title: Ophthalmic evaluation of children from the Tibet plateau with congenital heart disease.
abstract: OBJECTIVE
  To perform ophthalmic examinations to evaluate the ocular characteristics of children living in the Tibet plateau and diagnosed with congenital heart disease.
  
  
  METHODS
  Children with congenital heart disease underwent a conventional ocular examination including distant acuity test, slit-lamp examination, fundus examination, non-contact intraocular pressure measurement, measurement of corneal thickness, and fundus photography.
  
  
  RESULTS
  Forty-two Tibetan children, aged between 4 and 18 years and diagnosed with congenital heart disease, were enrolled in this study. The percentage of low visual acuity was 4.76%, mean intraocular pressure was (13.67 ± 2.15) mmHg, average corneal thickness was (492.55 ± 33.79) μm, 96.43% had an anterior chamber depth of 1/2 corneal thickness (CT), and 35.7% had an obvious fundus vascular tortuosity.
  
  
  CONCLUSIONS
  This study adds to the understanding of the ocular status of the population living in the Tibet plateau, thereby offering clinical evidence for the prevention and treatment of eye diseases in this area.
