This study aimed to investigate morphologic features of optic disc drusen (ODD) and peripapillary hyperreflective ovoid mass-like structures (PHOMS) in children, using enhanced depth imaging optical coherence tomography (EDI-OCT). It also assessed if the presence of these features were associated with decreased peripapillary retinal nerve fibre layer (RNFL) thickness. Retrospective observational study of children with ODD. All subjects underwent complete ophthalmic examination and multimodal imaging. ODD were identified on EDI-OCT as circumscribed hyporeflective spheroidal elements located in front of lamina cribrosa, fully or partially surrounded by a hyperreflective border. PHOMS were identified as hyperreflective ovoid structures located in the peripapillary circumference. Both associations between ODD and RNFL loss and PHOMS and RNFL loss were tested using chi-squared test. In total, 38 eyes of 20 children were analysed. PHOMS were present in 90% of patients. ODD and PHOMS were predominantly found in the nasal, superonasal and inferonasal sectors. A significant positive association was found between ODD and decreased RNFL thickness in the nasal (p = 0.02), superonasal (p = 0.05) and inferotemporal (p = 0.04) sectors. There was no significant association found with the presence of PHOMS. EDI-OCT allowed morphological analysis of ODD and PHOMS in children. Drusen were found to be distinct from PHOMS both in their appearance and impact on the RNFL. ODD are hyporeflective and appear on the ONH above the lamina cribrosa and were associated with decreased thickness of the RNFL. On the contrary, PHOMS are hyperreflective structures located around the ONH and were not associated with RNFL loss.

儿童视盘玻璃膜疣:使用 EDI-OCT 的形态学特征
本研究旨在利用增强深度成像光学相干断层扫描 (EDI-OCT) 研究儿童视盘玻璃膜疣 (ODD) 和视乳头周围高反射卵圆形肿块状结构 (PHOMS) 的形态特征。它还评估了这些特征的存在是否与视乳头周围视网膜神经纤维层(RNFL)厚度减少有关。 ODD 儿童的回顾性观察研究。所有受试者均接受了完整的眼科检查和多模态成像。 ODD 在 EDI-OCT 上被识别为位于筛板前面的外接低反射球体元素,完全或部分被高反射边界包围。 PHOMS 被鉴定为位于乳头周围的高反射卵圆形结构。 ODD 和 RNFL 损失以及 PHOMS 和 RNFL 损失之间的关联均使用卡方检验进行了测试。总共对 20 名儿童的 38 只眼睛进行了分析。 90% 的患者存在 PHOMS。 ODD 和 PHOMS 主要见于鼻腔、鼻上腔和鼻下腔。在鼻部 (p = 0.02)、鼻上部 (p = 0.05) 和颞下部 (p = 0.04) 区域,ODD 与 RNFL 厚度减少之间存在显着正相关。没有发现与 PHOMS 的存在存在显着关联。 EDI-OCT 允许对儿童 ODD 和 PHOMS 进行形态学分析。研究发现玻璃疣在外观和对 RNFL 的影响上都与 PHOMS 不同。 ODD 是低反射性的,出现在筛板上方的 ONH 上,并与 RNFL 厚度减少相关。相反,PHOMS 是位于 ONH 周围的高反射结构,与 RNFL 损失无关。
