    Background/Aims: To report the 1 year experience of the Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) telemedicine initiative.

    Methods: 42 consecutively enrolled infants who met ROP examination criteria were screened between 12/1/2005 through 11/30/2006 with the RetCam II and evaluated by the SUNDROP reading center at Stanford University. Nurses obtained 5 images in each eye. All patients also received a dilated examination by the author within one week of discharge from the hospital. Outcomes included referral-warranted disease, need for treatment, and anatomic outcomes. Referral-warranted disease was defined as any Early Treatment Retinopathy of Prematurity (ROP) Disease Type 2 or greater, or any plus disease. Retrospective analysis of 84 eyes, 131 unique examinations and 1315 unique images the SUNDROP archival data is here reported.

    Results: In the initial 12-month period, the SUNDROP telemedicine screening initiative had not missed any referral warranted ROP. Calculated sensitivity and specificity was 100% and 95%, respectively. No patient progressed to retinal detachment or other adverse outcomes.

    Conclusions: The SUNDROP telemedicine screening initiative for ROP has proven to have a high degree of sensitivity and specificity for identification of referral warranted disease. These results indicate telemedicine may improve accessibility of ROP screening.
