Abstract: Purpose: To study the morphologic alterations around the optic disc by spectral optical coherence tomography (SD OCT) in eyes with high myopia.<br />Patients and 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.<br />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.<br />Conclusion: Perpapillary changes detected by SD OCT in eyes in high myopia are relatively frequent and don't always present a clinical or ophthalmoscopic changes.<br /> (Copyright © 2014 Elsevier Masson SAS.
