title: Can vitreous fluorophotometry predict the necessity for photocoagulation? A 5-year follow-up study.
abstract: OBJECTIVE
  To examine the long-term outcome of vitreous fluorophotometry including the predictability of retinopathic proliferative development in diabetic subjects.
  
  
  METHODS
  21 diabetic subjects were examined by long-term kinetic vitreous fluorophotometry and their barrier properties, as revealed by a permeability-index, were compared to a group of normal subjects. 13 diabetics were classified as having a high permeability-index, while 8 diabetics were classified as having a low permeability-index. The two groups were followed for 5 years with regard to development of proliferative retinopathy.
  
  
  RESULTS
  6 of 13 diabetics with a high permeability-index developed proliferative retinopathy within the 5-year follow-up period. This was in contrast to the low permeability-index group where none of 8 diabetics developed proliferative retinopathy.
  
  
  CONCLUSIONS
  An increased permeability-index points towards an increased risk of development of proliferative retinopathy.
