title: Transvitreal endoresection of refractory retinal capillary hemangioblastoma after feeder vessel ligation.
abstract: OBJECTIVE
  Retinal capillary hemangioma (RCH) is a developmental vascular tumor occurring sporadically or associated with Von Hippel-Lindau syndrome. Treatment for large solitary RCH is challenging. Laser, cryotherapy, radiotherapy, photodynamic therapy, and en bloc resection for advanced cases have been described in the literature without consensus on standard management.
  
  
  METHODS
  A novel technique of 20-gauge transvitreal endoresection of solitary peripheral RCH after ligating the feeder vessels is described.
  
  
  RESULTS
  Tumors were successfully resected after ligating the feeder vessels bimanually in a closed and more controlled ocular environment. Feeder vessel ligation is intended to compensate for the involution time of the caliber of feeder vessels, when postoperative hemorrhage is more likely to occur. Another advantage of ligating the blood vessels is to secure hemostasis without using heavy endocautery. Postoperatively, proliferative vitreoretinopathy remains a concern.
  
  
  CONCLUSIONS
  Pending a larger randomized trial, performing endoresection in RCH that is large and unresponsive to conventional treatment is an acceptable option.
