title: THERAPEUTIC OUTCOMES AFTER ENDORESECTION OF COMPLEX RETINAL CAPILLARY HEMANGIOBLASTOMA.
abstract: OBJECTIVE
  To evaluate the anatomical and functional outcomes after endoresection of complex retinal capillary hemangioblastoma (RCH).
  
  
  METHODS
  Retrospective case series of 12 patients (13 eyes), all treated with pars plana vitrectomy, endodiathermy of feeding and draining vessels, endoresection of RCH and silicone oil injection.
  
  
  RESULTS
  The mean age at the time of surgery was 32.5 ± 15.9 years. The mean follow-up duration after initial surgery was 50.5 ± 49.4 months. Indications for surgery included RCH with associated complications such as tractional retinal detachment in five eyes (38%), exudative retinal detachment in four eyes (31%), and combination of tractional retinal detachment and exudative retinal detachment in four eyes (31%). The dimensions of the resected RCHs were as follows: >3.0 mm in seven eyes (54%), >3.5 mm in three eyes (23%), and >4.0 mm in three eyes (23%). No tumor was located closer than 10 mm to the optic nerve or fovea. Anatomical success after initial surgery was 92%. One eye had a second vitreoretinal procedure owing to recurrent RD. The mean preoperative Snellen visual acuity was 20/303. The mean Snellen visual acuity at the final visit was 20/73. At the final visit, visual acuity had improved in seven eyes (54%), and six eyes (46%) were stable. Short-term complications included recurrent proliferative vitreoretinopathy in one eye (8%), transient ocular hypertension requiring topical antiglaucoma treatment in four eyes (31%), and long-term complications included progression of cataract in seven eyes (54%).
  
  
  CONCLUSIONS
  Combined pars plana vitrectomy, endodiathermy of feeding and draining vessels, endoresection of RCH, and silicone oil injection may be an effective treatment option for complex RCH, achieving high anatomical success and stable or even improved visual acuity, acceptable rates of disease- and treatment-related complications, and minimal need for retreatment.
