Purpose: To determine the incidence of retinopathy of prematurity (ROP) in Gansu, China by combining bedside examinations with remote RetCam (Clarity Medical Systems, Pleasanton, CA, USA) diagnosis.
Methods: ROP screening via indirect ophthalmoscopy followed by RetCam imaging was performed from 2014 to 2015. Three ROP-experienced ophthalmologists interpreted images remotely. Incidence of ROP was determined by combining bedside and telemedicine diagnoses.
Results: Of 139 examined infants and 137 complete records, 20 (14.6%) patients developed ROP, with 11 (8.0%) stage 1, six (4.4%) stage 2, and three (2.2%) stage 3 based on combined diagnoses. Perinatal asphyxia was significantly associated with ROP incidence (p = 0.01). ROP incidence by combined diagnosis (20/137 or 14.6%) versus clinician diagnosis alone (21/137 or 15.3%, p = 0.50) was similar. Telemedicine changed diagnoses in 4/21 (19.0%) ROP cases.
Conclusions: Telemedicine may be helpful in confirming ROP incidence and may serve as a training and support model for less experienced and professionally isolated ROP examiners.
