Comparison of Smartphone-Based Ophthalmoscopy With Dilated Ophthalmic Examination to Detect Ocular Pathologic Features

Purpose: To evaluate the ability of smartphone-based imaging to detect ocular pathologic features compared to dilated ophthalmic examination by retinal specialist ophthalmologists. Methods: 160 outpatients underwent dilated examination and smartphone ophthalmoscopy. The smartphone was equipped with a compact add-on that filtered and delivered the smartphone’s LED light coaxially to the camera, allowing a clear and convenient view of the retina. Results: K-values for all lesions (k ≥ 0.66) demonstrated substantial agreement between smartphone-based imaging and clinical examination. Conclusion: Smartphone ophthalmoscopy showed considerable agreement with clinical examination in the detection of ocular diseases, suggesting a potential role in screening environments for smartphone-based imaging
