title: [Prophylactic pan-coagulation from ischemic central vein occlusions? Practicability of the results from the Central Vein Occlusion Study Group].
abstract: OBJECTIVE
  Central vein occlusions (CVO) with an avascular area of more than 10 optic-disc areas are classified as ischemic by the Central Vein Occlusion Study Group (CVOSG). For patients without neovascularizations (NV) clinical controls every 4 weeks during the first 6 months are recommended instead of prophylactic pancoagulation (PC). In this study we examined the practicability of this recommendation.
  
  
  METHODS
  We analysed the records of 15 patients with ischemic CVO and no clinical signs of NV and no prophylactic PC retrospectively. All these patients developed a neovascular glaucoma (NVG) despite using the criteria of the CVOSG and were then treated with cyclophotocoagulation (CPC).
  
  
  RESULTS
  The time between first presentation and CPC was 4.4+/-2.9 months. Of these patients 7 developed a NVG within 4 weeks after initial presentation.
  
  
  CONCLUSIONS
  This study shows that NV and NVG may develop much faster than 4 weeks and can already be irreversible. Therefore it seems advisable to follow-up patients with increased risk factors even more frequently especially during the initial phase after CVO.
