PHOMS is an OCT finding that is nonspecific and can be seen in a number of optic nerve conditions including ODD and true disc edema. The presence of PHOMS should not be used to diagnose ODD. Clinicians should be aware of the significance and OCT appearance of PHOMS.

1 天前 · OCT angiography (OCTA) adds another diagnostic layer by assessing microvascular changes related to ODD. While drusen lack intrinsic vascularization, they can alter peripapillary capillary density. OCTA maps these vascular changes, distinguishing ODD-related perfusion abnormalities from glaucomatous or ischemic optic neuropathies.

In this review, the role of established and emerging optical coherence tomography (OCT) techniques in the diagnosis and management of ODD cases is reviewed. A practical approach is taken to explain how to optimise use of commercially available OCT technology in …

The introduction of enhanced depth imaging optical coherence tomography (EDI-OCT) has improved the visualization of more deeply buried ODD. There is, however, no consensus regarding the diagnosis of ODD using OCT. The purpose of this study was to develop a consensus recommendation for diagnosing ODD using OCT.

OCT has become increasingly useful as an adjunctive tool in the detection of optic disc drusen (ODD) and the workup for possible papilledema. ODD must have two key characteristics: They should be above the lamina cribrosa, and they should have a hyporeflective core.

2019年9月5日 · Advanced optic nerve imaging, including optical coherence tomography (OCT) can be used to diagnose and characterize ODD with very high resolution. Enhanced depth imaging (EDI-OCT) in particular has emerged as the optimal modality to directly visualize ODD.

Optic nerve head elevation can be associated with vision loss. This review provides an update regarding key features of optic disc drusen (ODD) compared with papilledema from increased intracranial pressure and optic disc edema from other causes.

视盘玻璃疣（ODD）是无细胞性沉积物，位于视盘的筛板前部。 大多数患者无明显临床症状，通常被忽视，也容易与全身高危疾病导致的视盘水肿相混淆。 目前主流观点认为，视神经纤维轴突代谢紊乱，导致细胞内线粒体钙化，轴突慢性崩解后钙化的线粒体不断释放到细胞外，导致细胞外钙浓度远较细胞内高，钙质不断积聚从而产生微小的钙化体，多个钙化体逐渐融合形成ODD。 增强深度成像OCT能敏感地检测ODD，其影像特征是被强反射边缘完整或部分包绕的弱反射核心 …

The development of enhanced depth imaging (EDI) for spectral-domain OCT (SD-OCT) by Spaide et al. has further improved the visibility of structures deep within the ONH, such as the lamina cribrosa (LC), ODD, and ODD-associated features.

The goal of the ODDS Consortium is to establish a reliable and consistent diagnosis of ODD using OCT for both clinicians and researchers. Better detection of ODD using OCT might, in time, improve differentiation between buried ODD and mild papilledema, but currently OCT requires further study to make it as the sole means of differentiation.
