To evaluate whether infrared video imaging can supplement traditional examination and imaging methods to identify and quantify symptomatic vitreous opacities. A prospective nonrandomized nonmasked series was performed that included eyes of consecutive patients with a primary complaint of symptomatic vitreous opacities. A macular vitreous opacity score (0-4) was developed to grade the size of the opacities in relation to the macula after refixation of up, down, left, and right saccades. Grade 0 indicated an absence of opacities. Grades 1 to 4 represented how many quadrants of the macula were obscured by opacities for more than 50% of the total video capture time (grade 1 = 1%-25%; grade 2 = 26%-50%, grade 3 = 51%-75%; grade 4 = 76%-100%). Grade 2 opacities were divided into subcategories 2A and 2B depending on whether they were central enough to obscure the fovea for more than 50% of the time. The study comprised 52 eyes of 40 patients. Thirty-two eyes (62%) with symptomatic vitreous opacities were grade 1, 6 (11%) were grade 2A, 6 (11%) were grade 2B, 5 (10%) were grade 3, and 3 (6%) were grade 4. Infrared video imaging is a useful supplement to traditional examination and imaging methods for the identification and quantification of symptomatic vitreous opacities. The macular vitreous opacity score can help standardize vitreous opacity documentation in the clinical setting for future case selection.
评估红外视频成像是否可以补充传统检查和成像方法，以识别和量化有症状的玻璃体混浊。进行了一项前瞻性非随机非盲法系列研究，纳入了以有症状玻璃体混浊为主诉的连续患者的眼睛。制定了黄斑玻璃体混浊评分（0-4分），用于在向上、向下、向左和向右扫视重新注视后，对混浊相对于黄斑的大小进行分级。0级表示无混浊。1至4级表示在视频总采集时间的50%以上，黄斑的多少个象限被混浊遮挡（1级=1%-25%；2级=26%-50%；3级=51%-75%；4级=76%-100%）。2级混浊根据其是否足够靠近中心，在50%以上的时间内遮挡中央凹，分为2A和2B亚类。该研究包括40例患者的52只眼睛。32只（62%）有症状的玻璃体混浊眼睛为1级，6只（11%）为2A级，6只（11%）为2B级，5只（10%）为3级，3只（6%）为4级。红外视频成像对于识别和量化有症状的玻璃体混浊是传统检查和成像方法的有用补充。黄斑玻璃体混浊评分有助于在临床环境中标准化玻璃体混浊的记录，以便未来进行病例选择。
