Peripapillary changes detected by SD OCT in eyes with high myopia.

Purpose To investigate the morphologic alterations around the optic disc by SD‐OCT with high myopia Methods One hundred eyes (54 patients) with high myopia (>‐6.00 diopters) were included. The participants had ophthalmologic examinations including stereoscopic fundus observations, OCT examinations. For OCT, multiple horizontal and vertical and cercle scans were obtained around the optic disc and fovea in each patient. Results Patients were mean age 43.2+/‐9.4 years, with a spherical‐equivalent refractive error of ‐11.26+/‐4.85 D and mean axial length of 27.65+/‐1.82 mm. A peripapillary detachment was detected by OCT in 8 eyes (8%) as a hyporeflective space intrachoroidally and subretinally. It was also observed within the tissue posterior to the conus in eyes without the typical ophthalmoscopic yellow‐orange lesions. Microfolds in the retinal vessels were detected at the conus edge in 40 of the highly myopic eyes (40%), and 10 of these eyes had paravascular cysts (10%). A retinoschisis was present at the site of the retinal vessels in 10 eyes (10%). Conclusion The SD OCT examinations demonstrated different types of peripapillary changes in highly myopic eyes. It is important to detect these peripapillary changes especially peripapillary detachment by OCT to be able to predict the later development of visually disabling conditions. [ABSTRACT FROM AUTHOR]
