title: [Retinal neovascularization with myelinated nerve fibers].
abstract: BACKGROUND
  The prevalence of myelinated retinal nerve fibers is 0.3%-0.6% of eyes. Although they often constitute benign lesions, they are rarely associated with retinal vascular abnormalities including preretinal neovascularization.
  
  
  METHODS
  A 31-year-old patient, with no previous pathological antecedents, consulted us for myodesopsia in her left eye. The exam found a visual acuity of 10/10 and a normal anterior segment in the two eyes. At the ophthalmoscopic examination of the left eye, we noted myelinated nerve fibers in the inferotemporal quadrant that were associated with a temporal neovascular bouquet covering area of 1.5 optic disks. A small amount of intravitreal hemorrhage was found. The ophthalmoscopic examination of the right eye was normal. The treatment consisted in sector-based photocoagulation with argon laser and cryotherapy.
  
  
  CONCLUSIONS
  The source of neovascularization in the myelinated retinal nerve fibers was discussed. Underlying retinal ischemia is the most probable mechanism. The treatment was based on sector-based or panretinal photocoagulation.
  
  
  CONCLUSIONS
  Preretinal neovascularization is a rare complication of myelinated nerve fibers. The earlier the care is given, the more complications can be avoided.
