- ItemAccuracy and reliability of remote retinopathy of prematurity diagnosis.(2006-03-14) Chiang, Michael F; Keenan, Jeremy D; Starren, Justin; Du, Yunling E; Schiff, William M; Barile, Gaetano R; Li, Joan; Johnson, Rose Anne; Hess, Ditte J; Flynn, John TTo determine the accuracy and reliability of retinopathy of prematurity ROP diagnosis using remote review of digital images by 3 masked ophthalmologist readers
- ItemAssessment of image-based technology: impact of referral cutoff on accuracy and reliability of remote retinopathy of prematurity diagnosis.(2006-06-16) Chiang, Michael F; Keenan, Jeremy D; Du, Yunling E; Schiff, William; Barile, Gaetano; Li, Joan; Hess, Ditte J; Johnson, Rose Anne; Flynn, John T; Starren, JustinTelemedicine has potential to improve the delivery quality and accessibility of ophthalmic care for infants with Retinopathy of Prematurity ROP Using a telemedicine screening strategy three potential diagnostic cutoffs may be used to define disease that warrants ophthalmologic referral presence of any ROP presence of moderate type 2 prethreshold ROP or presence of severe ROP requiring treatment This study examines the relationship between accuracy and reliability of diagnosis by three masked ophthalmologist graders at each of these diagnostic cutoffs The sensitivity specificity inter grader reliability and intra grader reliability showed significant variation depending on the diagnostic cutoff with best results at cutoffs of type 2 prethreshold ROP or treatment requiring ROP Before the large scale adoption of telemedicine for image based screening of diseases such as ROP standards defining clinically relevant referral cutoffs must be established and diagnostic accuracy and reliability at these cutoffs must be characterized
- ItemTelephotoscreening to detect retinopathy of prematurity: preliminary study of the optimum time to employ digital fundus camera imaging to detect ROP.(2002-05-08) Yen, Kimberly G; Hess, Ditte; Burke, Barbara; Johnson, Rose Anne; Feuer, William J; Flynn, John TLabor intensive screening of infants in the neonatal intensive care units is the only way presently to detect retinopathy of prematurity ROP Our purpose is to determine if RetCam 120 images Massie Research Laboratories Inc Dublin Calif acquired by a neonatal nurse can be used to screen for ROP by performing 2 screening sessions at 32 to 34 weeks examination 1 and 38 to 40 weeks examination 2 postconceptional age
