Fundus photography: retinal photos

Color eye photography is a diagnostic tool used for visual documentation of various eye structures. It allows the ophthalmologist to photograph the front of the eye, including the eyelids, conjunctiva, cornea, and iris, or the fundus, which includes the retina, its blood vessels, and the optic nerve. Its primary purpose is to create a baseline record that can be compared with future photographs, thereby tracking changes over time, such as lesion growth, hemorrhages, or alterations in optic nerve structure.

Color photography is recommended for a variety of medical conditions. In the front of the eye, it can document lesions on the eyelids or conjunctiva, opacities or foreign bodies in the cornea, and moles (nevi) in the iris. In the fundus, photography is crucial for monitoring retinal changes in diseases such as diabetic retinopathy, age related macular degeneration (AMD), and retinal vein occlusions. It also aids in documenting changes in the optic nerve head, characteristic of neurological diseases and glaucoma.

Before the test, it is important to have a referral from an ophthalmologist. If you have any previous eye photographs, it is advisable to bring them for comparison. If you wear contact lenses, you may be asked to remove them before the photography, so it is a good idea to bring cleaning solution and a storage case for your lenses. No fasting or other special preparation is typically required.

The test is performed while seated. The patient is asked to rest their chin on a support and focus their gaze on a specific point. A specialized camera images the required area of the eye. Sometimes, especially for fundus photography, eye drops will be instilled to dilate the pupils. Pupil dilation allows for a wider field of view and a more comprehensive look at the retina and optic nerve. During the photography, there may be camera flashes, which can cause brief and temporary glare.

Color eye photography is a non invasive test and is generally not painful. The risks associated with the test are minimal. The camera flashes may cause a mild, transient sensation of glare. If dilating drops were instilled, you may experience blurred vision, especially for near objects, and light sensitivity (glare) for several hours after the test. These effects typically resolve on their own.

After the test, you can receive the captured images. It is important to remember that the photograph itself does not constitute a medical diagnosis and does not replace a comprehensive eye examination by an ophthalmologist. The interpretation and evaluation of the photographs are performed by the referring ophthalmologist, according to the purpose of the referral and the clinical findings. If pupil dilation was performed, you should avoid driving or activities requiring sharp vision until your vision returns to a safe state, usually after several hours. It is advisable to arrange for someone to accompany you or use public transportation.
