PURPOSE
To validate the smartphone photography as a screening tool for amblyogenic conditions in children.
METHODS
Children between 5 to 8 years attending eye out patient department (OPD) were photographed (by an optometrist) with a smartphone to capture their pupillary red reflexes followed by clinical examination by the principal investigator (PI). The PI on the basis of clinical examination identified children with significant amblyogenic conditions and, subsequently, two ophthalmologists independently categorized the photographs on the basis of color, symmetry, and shape of the pupillary reflex into normal or abnormal. The identification of amblyogenic conditions on clinical examination was compared to that on photography. Refractive errors <3D and anisometropia <2D were excluded. Sensitivity, specificity, positive predictive value, and negative predictive value of smartphone photography screening were determined.
RESULTS
In all, 250 children were screened. Clinically 23.6% were harboring amblyogenic conditions. The mean sensitivity and specificity of screening by smartphone were 94% and 91%, respectively.
CONCLUSION
Smartphone photography is a reliable tool for detection of amblyogenic conditions in children.
目的
验证智能手机摄影作为儿童致弱视条件筛查工具的有效性。
方法
在眼科门诊就诊的 5 至 8 岁儿童，由验光师使用智能手机拍摄其瞳孔红色反射，随后由主要研究者（PI）进行临床检查。PI 根据临床检查结果确定具有明显致弱视条件的儿童，然后由两名眼科医生根据瞳孔反射的颜色、对称性和形状将照片独立分类为正常或异常。将临床检查确定的致弱视条件与摄影检查结果进行比较。排除等效球镜度<3D 和屈光参差<2D 的情况。确定智能手机摄影筛查的灵敏度、特异性、阳性预测值和阴性预测值。
结果
共筛查了 250 名儿童。临床检查发现 23.6%的儿童存在致弱视条件。智能手机筛查的平均灵敏度和特异性分别为 94%和 91%。
结论
智能手机摄影是一种可靠的儿童致弱视条件检测工具。
