Fundus cameras capture images of the retina, optic disc, macula, and posterior pole, offering a non-invasive way to visualize internal eye structures. It helps detect early signs of eye conditions such as diabetic retinopathy, glaucoma, and macular degeneration.
With growing demand for faster, more accurate screening tools, fundus imaging has become a routine part of clinical workflows worldwide. However, today’s cameras need features such as high-resolution imaging, enhanced low-light performance, and real-time connectivity.
In this blog, you’ll find out how fundus cameras are used across different clinical scenarios and how recent innovations are pushing the boundaries of their performance.
Popular Applications of Fundus Cameras
Diabetic retinopathy
Fundus photography is important for detecting and managing diabetic retinopathy. It helps visualize microaneurysms, hemorrhages, and vascular abnormalities in the retinal blood vessels caused by prolonged high blood sugar. With regular imaging, doctors can monitor disease progression and initiate timely treatment to preserve vision.
Glaucoma
Fundus cameras capture detailed images of the optic nerves, making them valuable in identifying early signs of glaucoma. Changes such as increased cupping and nerve fiber loss in the optic nerves can be tracked over time, enabling quick intervention.
Age-Related Macular Degeneration (AMD)
Fundus imaging plays a major role in monitoring AMD by showing drusen deposits and macular pigment changes in macula, the central part of the retina. It is useful for distinguishing between dry and wet forms of the disease.
Retinal detachment or tears
Early signs of retinal detachment or small tears can be caught through careful fundus examination. High-resolution images allow ophthalmologists to assess the peripheral retina, where detachments often begin. Prompt detection can prevent serious complications, including permanent vision loss.
Pre- and post-surgery evaluation
Before ocular surgery, fundus images help map the retinal condition and plan the procedure accurately. After surgery, they are used to monitor healing, check for infections, and ensure there are no new retinal issues. It supports a full-circle view of patient recovery and outcome tracking.
Retinal disease research
Fundus photography provides consistent, high-quality images for tracking disease biomarkers and evaluating treatment effects. Researchers rely on this imaging to ensure accuracy and reproducibility across clinical trials.
Routine eye exams
Even in general check-ups, fundus images can uncover hidden problems like hypertension, macular changes, or early signs of optic nerve damage. These scans make it easier to detect conditions before symptoms arise.
Emerging Innovations in Fundus Photography
AI and ML
Fundus Photography is no exception when it comes to the wave of AI/ML integration. Recent research has shown that AI-based DL algorithms for optic nerve disease performed well in differentiating glaucoma from non-glaucoma on color fundus photographs. AI-based retinal imaging tools are being adopted in clinical settings as well.
Combination with OCT
Optical Coherence Tomography refers to a non-invasive imaging approach that offers high-resolution cross-sectional visuals of the retinal layers beneath the surface. Fundus photography, on the other hand, provides detailed images of the surface. Together, they complement each other in providing a complete picture of the retinal health.
Augmented and Virtual Reality
Modern-day surgical procedures are adopting AR and VR systems into their workflows to enhance the surgeon’s vision. Fundus photographs could be overlaid with the surgeon’s field of view to guide surgical instruments with greater precision in AR-assisted retinal surgeries. These photographs can be used to create 3D models that support planning complex retinal surgeries.
The use of virtual reality glasses in surgeries
Multispectral imaging
Fundus cameras are able to capture image data at varying wavelengths across the electromagnetic spectrum beyond the visible light range. When combined with fundus photography, it captures retinal images at different wavelengths. These include infrared or UV, which can reveal additional details about the retina that are not visible in standard fundus photography.
