Clinical applications and future directions of smartphone fundus imaging

AI Generated Summary*

A review surveys smartphone-based retinal photography, covering technique, strengths, limits, clinical uses and future directions. Setups below USD 1000 are contrasted with table-top cameras exceeding USD 10,000. Cited diabetic retinopathy studies report sensitivity from 50% to 91% and specificity from 94% to 99% for detecting any disease, with 100% figures in severe cases. For retinopathy of prematurity, one comparison found 90% sensitivity and 100% specificity for plus disease, while agreement with indirect ophthalmoscopy spanned kappa values of 0.62 to 0.85. Applications in macular degeneration, vascular occlusions, hypertensive retinopathy, telemedicine, operating room confirmation and self-imaging are described. Image quality, narrow field of view, missing standardization, regulatory ambiguity and privacy risks remain concerns the review says must be addressed.
