Smartphone fundus photography offers a simple way to document optic nerve and retinal changes using readily available smartphones. This technique is crucial for eye care when traditional fundus cameras are unavailable.

Area of Science:

Ophthalmology
Medical Imaging
Optical Engineering

Background:

Smartphone fundus photography utilizes smartphone cameras with handheld indirect ophthalmoscopy lenses.
It serves as a vital tool for documenting optic nerve, retina, and retinal vessels when fundus cameras are inaccessible.
The widespread availability of smartphones enables retinal imaging in diverse clinical settings.

Purpose of the Study:

To review the optical principles of indirect ophthalmoscopy and fundus photography.
To provide a detailed step-by-step method for capturing high-quality retinal images using a smartphone.
To highlight the advantages and applications of smartphone-based retinal imaging.

Main Methods:

Review of optical principles governing indirect ophthalmoscopy and fundus photography.
