To compare refractive data of Plusoptix AO9 (Plusoptix, Inc., Atlanta, GA) and Spot (Welch Allyn, Skaneateles Falls, NY) photoscreeners with retinoscopy in pseudophakic eyes of children.
In this prospective study, patients underwent testing with the Plusoptix and Spot photoscreeners prior to their examination by a pediatric ophthalmologist masked to the results of both photoscreeners. Data including testability and estimated refractions were entered into a Research Electronic Data Capture database for statistical analysis. For bilateral pseudophakia, one randomly selected eye was included in the analysis.
Forty-four eyes were included, with a mean age of 7.4 ± 4.8 years. Refraction was estimated in all eyes using retinoscopy, but a refractive estimate was obtained in only 11.3% (5 of 44) of eyes using the Plusoptix binocularly and 63.6% (28 of 44) of eyes using the Spot. Compared to retinoscopy, the Plusoptix showed a mean difference of -0.80, 0.10, and -0.75 diopters (D) for sphere, cylinder, and spherical equivalent, respectively (P > .05). Comparable values for the Spot were 0.18, -0.26, and 0.05 D, respectively (P > .05). Compared to retinoscopy, the Plusoptix showed a mean absolute difference of 1.30, 0.80, and 1.25 D for sphere, cylinder, and spherical equivalent, respectively (P > .05). Similar values for the Spot were 1.38, 0.88, and 0.97 D, respectively (P > .05).
Refraction was estimated in a higher number of pseudophakic eyes of children using the Spot as compared to the Plusoptix. The Spot may be useful to evaluate myopic shift in pseudophakic eyes of children. [J Pediatr Ophthalmol Strabismus. 2016;53(3):146-149.].
比较Plusoptix AO9（Plusoptix公司，佐治亚州亚特兰大）和Spot（韦尔奇·阿林公司，纽约州斯卡奈特勒斯福尔斯）照片筛选仪与检影验光在儿童人工晶状体眼的屈光数据。
在这项前瞻性研究中，患者在接受儿科眼科医生检查之前，先使用Plusoptix和Spot照片筛选仪进行检测，该儿科眼科医生对两种照片筛选仪的结果均不知情。将包括可检测性和估计屈光度在内的数据录入研究电子数据采集数据库进行统计分析。对于双眼人工晶状体眼，随机选择一只眼睛纳入分析。
共纳入44只眼，平均年龄为7.4±4.8岁。所有眼睛均使用检影验光法估计屈光度，但使用Plusoptix双眼测量时，仅11.3%（44只眼中的5只）的眼睛获得了屈光度估计值，而使用Spot时为63.6%（44只眼中的28只）。与检影验光相比，Plusoptix的球镜、柱镜和等效球镜平均差异分别为-0.80、0.10和-0.75屈光度（D）（P>.05）。Spot的可比数值分别为0.18、-0.26和0.05 D（P>.05）。与检影验光相比，Plusoptix的球镜、柱镜和等效球镜平均绝对差异分别为1.30、0.80和1.25 D（P>.05）。Spot的相似数值分别为1.38、0.88和0.97 D（P>.05）。
与Plusoptix相比，使用Spot能在更多儿童人工晶状体眼中估计屈光度。Spot可能有助于评估儿童人工晶状体眼的近视偏移。[《小儿眼科与斜视杂志》。2016；53(3)：146 - 149。]
