Zero-delay switch technique in optical coherence tomography for duo enhanced vitreoretinal and choroidoscleral imaging in highly myopic eyes

摘要

Posterior staphyloma is a concave depression of the posterior shell of the eye globe that is frequently observed in highly myopic eyes. As hallmark lesion, it is seen in 90% of patients with high myopia and increases in prevalence with age.1 Highly myopic eyes with posterior staphylo-mata have a higher probability of visual disturbances; the stretching of the posterior fundus results in various lesions such as chorioretinal atrophy, choroidal neovasculariza-tion, lacquer cracks, foveoschisis, macular holes and serous macular detachments.2 It has been observed that with age, posterior staphylomata tend to deepen, and their morphological characteristics can change accompanied by an increased risk of complications.1
