To describe findings for orbital magnetic resonance imaging (MRI) in patients with age-related distance esotropia (ARDE).
We compared 31 orbital MRI from patients with ARDE (77±7 SD years) with 2 control groups: 32 orbits from individuals aged 18-50 years (33±8 SD years) and 16 orbits from individuals aged >60 years (77±7 SD years). MRI scans were acquired using 3D fast field echo in T1 sequence without fat saturation. Exclusion criteria for all groups were neurological or thyroid disease and a relevant ophthalmological history (e.g., high myopia, diplopia from another etiology, complicated cataract surgery, etc.). Muscle displacement and characteristics of the lateral rectus-superior rectus (LR-SR) intermuscular band were analyzed.
The analysis of the muscles and angles revealed a series of statistically significant differences (p<0.07) between the groups. Subjects with ARDE had LR pulley positions 1.32±0.19mm lower than in younger controls, and the medial rectus (MR) pulley positions were 0.68±0.19mm lower than in younger. Older controls had LR and MR pulley positions 0.85±0.20mm and 0.49±0.23mm lower than in younger. ARDE subjects had LR pulley positions 0.46±0.26mm lower than in older control group. The LR-SR band was absent in 35.5% of ARDE patients and in 12.5% of older control group (p=0.168).
MRI showed that displacements of LR and LR-SR band degeneration could facilitate the diagnosis of patients with ARDE.
描述年龄相关性远距离内斜视（ARDE）患者的眼眶磁共振成像（MRI）表现。
我们将31例ARDE患者（77±7标准差岁）的眼眶MRI与2个对照组进行比较：32例18 - 50岁个体（33±8标准差岁）的眼眶和16例60岁以上个体（77±7标准差岁）的眼眶。使用3D快速场回波T1序列且不进行脂肪饱和的情况下进行MRI扫描。所有组的排除标准为神经或甲状腺疾病以及相关眼科病史（如高度近视、其他病因导致的复视、复杂白内障手术等）。分析肌肉移位情况以及外直肌 - 上直肌（LR - SR）肌间带的特征。
肌肉和角度分析显示各组之间存在一系列具有统计学意义的差异（p<0.07）。ARDE患者的LR滑车位置比年轻对照组低1.32±0.19mm，内直肌（MR）滑车位置比年轻组低0.68±0.19mm。老年对照组的LR和MR滑车位置比年轻组分别低0.85±0.20mm和0.49±0.23mm。ARDE患者的LR滑车位置比老年对照组低0.46±0.26mm。35.5%的ARDE患者和12.5%的老年对照组患者不存在LR - SR带（p = 0.168）。
MRI显示LR移位和LR - SR带退变有助于ARDE患者的诊断。
