This story is part of a series on current advances in regenerative medicine. This piece is part of a series dedicated to improving the eyes and restoring vision.

In 1999, I defined regenerative medicine as a collection of interventions that restore normal function to tissues and organs damaged by disease, injured by trauma, or worn out over time. I include a full spectrum of chemical, gene and protein-based drugs, cell-based therapies, and biomechanical interventions that achieve that goal.

Glaucoma is a leading cause of irreversible blindness and disability worldwide. This is a group of eye conditions that damage the optic nerve, which connects the eye to the brain, causing vision loss. Glaucoma is the second leading cause of blindness globally, according to a systematic review and meta-analysis of global causes of blindness and distance vision loss by the Brian Holden Vision Institute.

The global prevalence of glaucoma is expected to increase from 76 million people in 2020 to 111.8 million by 2040. This increase in the prevalence of glaucoma will have a significant economic impact on health care systems and individual patients. Traditional methods of diagnosing glaucoma and tracking its progression using standard technology are challenging in clinical practice. However, using artificial intelligence (AI) and deep learning (DL) algorithms in health care may improve the diagnosis and screening of glaucoma.

How is Artificial Intelligence used to diagnose eye problems?

In their recent article, a team from Nanjing Medical University in China explained and illustrated the process of using artificial intelligence and deep learning-based algorithms to diagnose eye-related disorders and diseases.

Generally speaking, diagnosing glaucoma using AI involves carefully processing various data such as optic disc photos, visual fields, and intraocular pressure. The algorithm eliminates noise, artifacts, and irrelevant information to ensure accurate results while learning specific features and patterns associated with glaucoma through training. It is rigorously tested in the validation phase to confirm its effectiveness. If successful, it is further evaluated in the testing phase to ensure a reliable diagnosis.

When algorithms are implemented in clinical practice, physicians collect data such as optic disc photographs, visual fields, and intraocular pressure readings from patients and preprocess the data before applying the algorithm to diagnose glaucoma. Are.

Role of deep learning in glaucoma diagnosis

One of the essential roles of deep learning in glaucoma diagnosis is the ability to detect and differentiate normal eyes from those with early-stage glaucoma. Deep learning models trained from fundus photographs can identify specific fundus lesions in glaucoma, including abnormalities of the retinal nerve fiber layer. This will allow for earlier diagnosis of glaucoma and potentially reduce the risk of vision loss.

Furthermore, deep learning algorithms trained from optical coherence tomography (OCT) data can detect microstructural damage caused by glaucoma and its progression over time. Deep learning algorithms are proving to be more accurate than manual or automated segmentation methods in identifying early signs of glaucoma, according to research conducted by Wake Forest School of Medicine in North Carolina.

Deep learning can also detect glaucoma from fundus image regions outside the optic nerve head (ONH), as seen in a study by a team in Sydney, Australia. This is highly promising for the broader clinical applicability of deep learning in computer-assisted glaucoma screening and follow-up. It can also provide a comprehensive evaluation of the retina, helping physicians detect early symptoms of glaucoma that may have gone unnoticed.

Benefits of Artificial Intelligence and Deep Learning for Diagnosis

Duke Eye Center at Duke University reviewed the benefits of using sophisticated deep learning algorithms for glaucoma diagnosis. They found that these algorithms can provide diagnoses significantly faster than traditional methods, increasing efficiency and expediting treatment plans. Additionally, the accuracy of these algorithms is superior to traditional methods, enabling early detection and intervention, which can effectively stop disease progression. This improves patient outcomes and reduces health care costs associated with late-stage treatments.

Deep learning algorithms have tremendous potential to improve medical care access, especially for underserved populations living in remote areas without access to ophthalmologists. These algorithms allow patients in these areas to receive timely and accurate diagnoses, leading to better health care outcomes and reducing health care disparities. These algorithms enable eye care services to be accessed equally, regardless of location.

Additionally, health care professionals can use deep learning algorithms to reduce clinical variability, leading to more reliable and accurate assessments. This, in turn, creates greater confidence in the accuracy of medical diagnoses and promotes improvements in patient care.

Challenges of implementing deep learning in clinical practice

Despite promising results, several challenges must be addressed when implementing deep learning algorithms for glaucoma detection in clinical practice.

One of the primary challenges arises from the need for greater standardization in the data sets used to train these algorithms. Since different research studies and healthcare institutions may use different data collection techniques and formats, it becomes important to establish standardized data sets that can be used to train learning algorithms specific for the diagnosis of glaucoma. Can be done equally.

Apart from data standardization, another barrier is the accessibility of these algorithms to all healthcare providers. Although they have shown great promise in glaucoma detection, their deployment and use may not be feasible for all health care professionals, especially those serving underserved populations. Therefore, there is a need to develop user-friendly interfaces and tools that enable healthcare providers from different backgrounds to effectively use deep learning algorithms in detecting glaucoma among underserved populations.

setting our sights on the future

Glaucoma is a significant cause of blindness and disability worldwide. Its prevalence will increase in the coming years, leading to significant impacts on health care systems and individual patients. Advances in artificial intelligence and deep learning algorithms in health care have shown great potential in improving the accuracy of diagnosing glaucoma and tracking its progression. These algorithms could provide faster and more accurate diagnoses, potentially improving access to care for underserved populations and reducing diagnostic variability.

However, some challenges must be addressed before deep learning algorithms for glaucoma detection can be widely implemented in clinical practice. These include a focus on data standardization and improving access. By addressing these challenges, we can pave the way for widespread and accurate implementation of deep learning algorithms in clinical practice for early detection and management of glaucoma.
