To evaluate the use of high-definition, wireless video recording Pivothead glasses in streamed strabismus examinations.
A pediatric ophthalmologist wearing Pivothead glasses simultaneously performed and recorded strabismus examinations, which were completed in primary gaze, with and without correction, and at distance and near. Parameters included category of strabismus, angle measurements, and ocular motility. Another pediatric ophthalmologist, masked to clinical findings, reviewed and graded live video feed. At least 3 months later, both pediatric ophthalmologists graded the stored videos. Agreement was determined by unweighted kappa for categorical variables, intraclass coefficient for continuous variables, and percent agreement.
A total of 100 videos were recorded for 37 enrolled patients aged 4-16 years. Agreement between streamed and in-person examinations was perfect for both horizontal and vertical (κ = 1.0) deviations. Agreement for degree manifest (tropia vs intermittent tropia vs phoria) was almost perfect for all deviations (κ = 0.94). Agreement was excellent for angle measurements of both horizontal (ICC = 0.95) and vertical (ICC = 0.91) deviations. Inferior and superior oblique agreement was 93% and 98%, respectively. Similar agreement was also observed between store-and-forward versus gold standard examinations.
Real-time video feed obtained with video glasses can be read with a high degree of reliability for detecting strabismus category, angle, and extraocular motility.
评估高清、无线视频录制 Pivothead 眼镜在斜视检查中的应用。
一名小儿眼科医生佩戴 Pivothead 眼镜同时进行并记录斜视检查,检查在第一眼位、矫正和不矫正时以及在远距和近距进行。参数包括斜视类型、角度测量和眼球运动。另一名小儿眼科医生对临床发现进行了评估和分级。至少 3 个月后,两名小儿眼科医生对存储的视频进行了分级。使用无序分类变量的未加权 Kappa、连续变量的组内系数和百分比一致性来确定一致性。
共记录了 37 名 4-16 岁患者的 100 个视频。实时检查和面对面检查在水平和垂直(κ=1.0)偏差方面具有完美的一致性。对于所有偏差,显性(斜视与间歇性斜视与隐斜视)的分级一致性几乎是完美的(κ=0.94)。水平(ICC=0.95)和垂直(ICC=0.91)偏差的角度测量一致性非常好。下斜肌和上斜肌的一致性分别为 93%和 98%。存储和转发与金标准检查之间也观察到了类似的一致性。
通过视频眼镜获得的实时视频可以高度可靠地用于检测斜视类型、角度和眼外肌运动。
