title: [Peripapillary changes detected by SD OCT in eyes in high myopia].
abstract: OBJECTIVE
  To study the morphologic alterations around the optic disc by spectral optical coherence tomography (SD OCT) in eyes with high myopia.
  
  
  METHODS
  Two hundred eyes (113 patients) with high myopia were included. The participants had complete ophthalmologic examinations and OCT examinations. OCT scans were obtained around the optic in each patient.
  
  
  RESULTS
  We detected by OCT, a peripapillary detachment in 14 eyes (11.0%), a retinischisis peripapillary in 10 eyes (5%) and paravascular abnormalities as microfolds and paravascular cysts in 80 eyes (40%). A statistically significant difference was found between patients with microfolds paravascular and the rest of the patients concerning age (P=0.0034) and axial length (P=0.001). The patients with paravascular cysts were older (P=0.0022), had a greater axial length (P=0.0044) and a high rate of posterior staphyloma compared to other patients.
  
  
  CONCLUSIONS
  Perpapillary changes detected by SD OCT in eyes in high myopia are relatively frequent and don't always present a clinical or ophthalmoscopic changes.
