PURPOSE: To evaluate a large series of patients affected by high myopia using multiplanar imaging provided by en face optical coherence tomography (OCT). DESIGN: Observational cross-sectional study. METHODS: En face OCT longitudinal cross-sectional B scans and coronal C scans were obtained in 200 eyes of 100 patients with myopia greater than -6 diopters and evidence of posterior staphyloma at fundus examination and at ultrasound B-scan evaluation. RESULTS: A macular hole was present in three eyes (1.5%). We detected posterior retinal detachment in 37 cases (18.5%). In 15 eyes (7.5%) detachment was associated with a macular hole. In the remaining 22 eyes (11%), the detachment was located in the area of the staphyloma, and was associated with vitreoretinal traction in four eyes (18.2%) of 22 eyes. There was evidence of detachment of the internal limiting membrane (ILM) in 12 eyes (6%) and retinoschisis in 27 (13.5%) of 200 eyes. Retinal vascular microfolds were detected in 40 eyes (20%), and occurred in all cases of peripapillary retinal detachment, ILM detachment, and retinoschisis. Paravascular microcysts occurred in three eyes (1.5%), and peripapillary detachment of the pigment epithelium in 10 eyes (5%). CONCLUSIONS: En face OCT provides accurate imaging of retinal abnormalities in high myopia and allows width measurement and point-to-point localization of alterations. Thus, it can represent a noninvasive way to detect minimal changes during follow-up. Posterior detachment in the absence of a macular hole seems to be related to vitreoretinal traction, staphyloma, and inward forces exerted by rigid retinal vessels and ILM. En face OCT-assisted surgery of macular holes could help to plan removal of premacular tractional structures.
