Abstract

BACKGROUND:

To evaluate the efficacy of wide-field digital retinal imaging for retinopathy of prematurity screening.

DESIGN:

Retrospective study in a quaternary public neonatal intensive care unit.

PARTICIPANTS:

A total of 108 premature infants screened for retinopathy of prematurity.

METHODS:

Retrospective chart and photo review were performed on participants screened by both serial wide-field digital retinal imaging and concurrent binocular indirect ophthalmoscopy. Review of captured digital photos was performed independently by a masked reader. Using the binocular indirect ophthalmoscopy findings as the gold standard, the efficacy of wide-field digital retinal imaging in detecting treatment-requiring retinopathy of prematurity, defined as type 1 prethreshold disease, was determined.

MAIN OUTCOME MEASURES:

Sensitivity and specificity of wide-field digital retinal imaging in detecting treatment-requiring retinopathy of prematurity.

RESULTS:

Treatment-requiring retinopathy of prematurity was detected in 11 infants by both binocular indirect ophthalmoscopy examination and telemedicine images taken at the same visit. Wide-field digital retinal imaging has a sensitivity of 100% (95% CI: 76.2-100%) and a specificity of 97.9% (95% CI: 93.4-99.7%) in detecting infants with treatment-requiring retinopathy of prematurity. Positive and negative predictive values of wide-field digital retinal imaging were 84.6% (95% CI: 57.8-97.3%) and 100% (95% CI: 96.9-100%), respectively.

CONCLUSIONS:

Wide-field digital retinal imaging is accurate, reliable and efficient in detecting treatment-requiring retinopathy of prematurity. Incorporating wide-field digital retinal imaging with telemedicine in standard retinopathy of prematurity management can potentially improve delivery, accessibility, quality and cost of retinopathy of prematurity care.
