Which imaging technique is commonly used to evaluate the retina?

Fundus photography is a widely used imaging technique in optometry to evaluate the retina. This method captures detailed photographic images of the interior surface of the eye, particularly the retina, optic disc, and macula. The high-resolution images produced by fundus photography allow clinicians to assess the health of the retinal structures, monitor changes over time, and diagnose various ocular conditions such as diabetic retinopathy, age-related macular degeneration, and glaucoma.

One of the key advantages of fundus photography is its ability to provide a permanent record of the retinal condition, which can be compared in future examinations. Additionally, it is a non-invasive procedure that does not involve radiation, making it safe for patients.

In contrast to fundus photography, ultrasound imaging is generally used for examining the overall structure of the eye and detecting conditions such as retinal detachment, rather than providing a detailed view of the retina itself. CT scans and MRIs, while useful for imaging various conditions in the body, are not typically employed for routine retinal evaluation due to their higher cost, complexity, and radiation exposure.
