All patients were first examined with binocular indirect ophthalmoscopy (BIO), which served as the reference standard. The patients were then assessed by two devices. Imaging quality, ability to judge the zone and stage of ROP, agreement with the BIO results, vital signs, and pain scores were compared between these two devices. In total, 142 eyes of 71 infants were included. For the smartphone-based fundus photography, image quality was graded excellent or acceptable in 91.4% of examinations, although it was still significantly inferior to that of the contact imaging device (p &lt; 0.001). The smartphone-based fundus photography images had moderate agreement with the BIO results regarding the presence or absence of plus disease (Cohen\u2019s \u03ba = 0.619), but evaluating the zone (p &lt; 0.001) and stage (p &lt; 0.001) of ROP was difficult. Systemic parameters, except for heart rate, were similar between the two imaging devices (all p &gt; 0.05). In conclusion, although the smartphone-based fundus photography showed moderate agreement for determining the presence or absence of plus disease, it failed to identify the zone and stage of ROP.<\/jats:p>","DOI":"10.3390\/diagnostics12040945","type":"journal-article","created":{"date-parts":[[2022,4,10]],"date-time":"2022-04-10T06:02:54Z","timestamp":1649570574000},"page":"945","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Comparison of RetCam and Smartphone-Based Photography for Retinopathy of Prematurity Screening"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1689-9730","authenticated-orcid":false,"given":"Jui-Yen","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, Taoyuan 333, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6814-6530","authenticated-orcid":false,"given":"Eugene Yu-Chuan","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, Taoyuan 333, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alay S.","family":"Banker","sequence":"additional","affiliation":[{"name":"Banker\u2019s Retina Clinic and Laser Centre, Navrangpura, Ahmedabad 380009, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4994-8391","authenticated-orcid":false,"given":"Kuan-Jen","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, Taoyuan 333, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yih-Shiou","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, Taoyuan 333, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi-Chun","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, Taoyuan 333, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3053-433X","authenticated-orcid":false,"given":"Jhen-Ling","family":"Huang","sequence":"additional","affiliation":[{"name":"Center for Big Data Analytics and Statistics, Chang Gung Memorial Hospital, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei-Chi","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Chang Gung Memorial Hospital, Linkou Medical Center, Taoyuan 333, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"311","DOI":"10.1001\/archopht.123.3.311","article-title":"15-year outcomes following threshold retinopathy of prematurity: Final results from the multicenter trial of cryotherapy for retinopathy of prematurity","volume":"123","author":"Palmer","year":"2005","journal-title":"Arch.
