About the paper:

Purpose: The presence of red pupillary reflex, with central fixation is an indirect sign of healthy vision.
Smartphones and cameras have inbuilt red reflex blocking. MDEyeCare, is a new app available for iOS that is designed to view the red pupillary reflex in non-dilated children.
Methods: In this pilot study, 257 children were screened with the new app and results were compared to dilated ophthalmic exam with cycloplegic retinoscopy.

Results: The average age was 6.5 years (3 months – 12 years) and 56% were males. There were 25% whites, 20% blacks, 50% Hispanics, 3.5% Asians and 1.5% mixed race.
The app diagnosed amblyogenic refractive error in 91% of patients and detected abnormal fundus finding in 6/7 patients (diffuse choroidal hemangioma was not detected by the app).

Conclusion: Photoscreening with the new app, has a good correlation especially in white and hispanic patients. For patients with darker pigmentation the app needs to be optimized and larger studies to determine sensitivity is required.
