Objectives

This paper evaluates the accuracy of the Eye-N-JOY (ENJ), a novel device (Patent no. US 9844317 B2), for identifying the presence of amblyopic risk factors. This device was developed to assess both visual acuity, ocular alignment, and eye movement; all while watching images on a tablet screen.

Methods

A prospective, single-center, comparison study. Participants were examined by the ENJ first and then underwent a comprehensive full eye examination by pediatric ophthalmologists including cycloplegic refraction. Both the technician operating the ENJ and the physicians were masked to each other’s findings. Children aged 18–72 months (1.5 to 6 years) attending a tertiary medical center for a full standard pediatric ophthalmology examination were included. The visual acuity and alignment were compared between the ENJ and the gold standard full ophthalmologic examination. The differences were noted, and the sensitivity and specificity were calculated.

Results

A total of 51 children were enrolled, 33 (64.7%) girls, aged 18–72 months. All children successfully completed the examination by the ENJ. No significant difference between the ENJ and the reference examination was detected in visual acuity measurements in both eyes (Pv = 0.553 for the right eye and 0.803 for the left). Overall agreement between all referral indications between the ENJ and reference examination was 84.3%, with 90.9% agreement in VA referral criteria and 90.1% in alignment referral criteria.

Conclusions

Eye-N-Joy can reliably examine both visual acuity and ocular misalignment in verbal and pre-verbal children.

一种评估不会说话和说话的儿童弱视危险因素的新型装置——一项试点研究

 目标

本文评估了 Eye-N-JOY (ENJ) 的准确性，这是一种新型设备（专利号 US 9844317 B2），用于识别弱视危险因素的存在。该设备的开发目的是评估视力、眼球排列和眼球运动；在平板电脑屏幕上观看图像的同时。

 方法

一项前瞻性、单中心比较研究。参与者首先接受 ENJ 检查，然后由儿科眼科医生进行全面的眼部检查，包括散瞳验光。操作 ENJ 的技术人员和医生都对彼此的发现不知情。年龄在 18 至 72 个月（1.5 至 6 岁）的儿童到三级医疗中心接受全面标准的儿科眼科检查。对 ENJ 和金标准全面眼科检查之间的视力和排列进行了比较。记录差异，并计算敏感性和特异性。

 结果

共有 51 名儿童入组，其中 33 名女孩（64.7%），年龄 18-72 个月。所有孩子都顺利完成了 ENJ 的考试。在双眼视力测量中，ENJ 与参考检查之间没有检测到显着差异（右眼P v = 0.553，左眼 P v = 0.803）。 ENJ 和参考检查之间所有转诊指征的总体一致性为 84.3%，其中 VA 转诊标准的一致性为 90.9%，一致性转诊标准的一致性为 90.1%。

 结论

Eye-N-Joy 可以可靠地检查语言和语言前儿童的视力和眼部错位。
