En Face Optical Coherence Tomography of the Poterior Pole in High Myopia Original Reearch Article

Purpoe To evaluate a large erie of patient affected by high myopia uing multiplanar imaging provided by en face optical coherence tomography (OCT). Deign Obervational cro-ectional tudy. Method En face OCT longitudinal cro-ectional B can and coronal C can were obtained in 200 eye of 100 patient with myopia greater than –6 diopter and evidence of poterior taphyloma at fundu examination and at ultraound B-can evaluation. Reult A macular hole wa preent in three eye (1.5%). We detected poterior retinal detachment in 37 cae (18.5%). In 15 eye (7.5%) detachment wa aociated with a macular hole. In the remaining 22 eye (11%), the detachment wa located in the area of the taphyloma, and wa aociated with vitreoretinal traction in four eye (18.2%) of 22 eye. There wa evidence of detachment of the internal limiting membrane (ILM) in 12 eye (6%) and retinochii in 27 (13.5%) of 200 eye. Retinal vacular microfold were detected in 40 eye (20%), and occurred in all cae of peripapillary retinal detachment, ILM detachment, and retinochii. Paravacular microcyt occurred in three eye (1.5%), and peripapillary detachment of the pigment epithelium in 10 eye (5%). Concluion En face OCT provide accurate imaging of retinal abnormalitie in high myopia and allow width meaurement and point-to-point localization of alteration. Thu, it can repreent a noninvaive way to detect minimal change during follow-up. Poterior detachment in the abence of a macular hole eem to be related to vitreoretinal traction, taphyloma, and inward force exerted by rigid retinal veel and ILM. En face OCT-aited urgery of macular hole could help to plan removal of premacular tractional tructure.
