目的:使用动态超宽场红外共聚焦扫描激光检眼镜(IRcSLO)描述玻璃体混浊的外观。
方法:回顾性病例系列。
方法:使用动态超宽场IRcSLO成像分析了主诉肌营养不良患者的眼睛(NidekMirante,NidekCo.,Ltd.,Gamagori,Japan),并根据玻璃体混浊严重程度量表进行分类。
结果:本研究纳入21例患者的30只眼。平均年龄为56岁。症状持续时间从1天到超过365天。玻璃体漂浮物最常见的原因是玻璃体后脱离(63.3%),其次是玻璃体脱水(23.3%),小行星透明病(10%)和玻璃体出血(3.3%)。3只眼睛的不透明度被列为1级(10%),10只眼睛中的2级(33.3%),11只眼睛中的3级(36.6%),4级两只眼睛(6.6%)和5级四只眼睛(13.3%)。1级混浊患者比2级或更高混浊患者年轻。可以在0%的1级混浊眼睛中识别出可见的Weiss环,40%的眼睛有二级混浊,100%的眼睛有3级混浊,100%的眼睛有四级混浊。在患有5级混浊的患者中,无法识别Weiss戒指。
结论:动态超宽视野IRcSLO成像是评估玻璃体漂浮物患者的有用工具。它允许数字的准确可视化,密度,以及玻璃体混浊投射在视网膜很宽区域的阴影的行为,与患者对漂浮物的感知呈正相关。
OBJECTIVE: To describe the appearance of vitreous opacities using dynamic ultra-widefield infrared confocal scanning laser ophthalmoscopy (IRcSLO).
METHODS: Retrospective case series.
METHODS: Eyes of patients complaining of myodesopsia were analyzed using dynamic ultra-widefield IRcSLO imaging (Nidek Mirante, Nidek Co., Ltd., Gamagori, Japan), and classified according to a vitreous opacity severity scale.
RESULTS: Thirty eyes of 21 patients were included in this
study. The average age was 56 years. Symptom duration ranged from 1 to more than 365 days. The most common cause of vitreous floaters was posterior vitreous detachment (63.3%), followed by vitreous syneresis (23.3%), asteroid hyalosis (10%) and vitreous hemorrhage (3.3%). Opacities were classified as Grade 1 in three eyes (10%), Grade 2 in 10 eyes (33.3%), Grade 3 in 11 eyes (36.6%), Grade 4 in two eyes (6.6%) and Grade 5 in four eyes (13.3%). Patients with Grade 1 opacities were younger than patients with opacities Grade 2 or greater. A visible Weiss ring could be identified in 0% of eyes with Grade 1 opacities, 40% of eyes with Grade 2 opacities, 100% of eyes with Grade 3 opacities, and 100% of eyes with Grade 4 opacities. In patients with Grade 5 opacities, a Weiss ring could not be identified.
CONCLUSIONS: Dynamic ultra-widefield IRcSLO imaging is a useful tool to evaluate patients with vitreous floaters. It allows for accurate visualization of the number, density, and behavior of the shadows that vitreous opacities project over a very wide area of the retina, which has a positive correlation with patient perception of floaters.
