Appointed by King Khaled as the consulting engineer to the Royal Court, he played a pivotal role in the country’s economic evolution and educational transformation, participating in close to 100 major construction projects in the Kingdom, including that of the largest eye hospital in the Middle East – the King Khaled Eye Specialist Hospital.

Al-Rashid, who lost vision in one eye as a child, first met David Tse 27 years ago and credits him for preserving the sight in his other eye. Through the years they forged a strong connection, which led to Al-Rashid’s generous philanthropy. “Dr. Al-Rashid is a rare blend of intelligence, experience, imagination, and uncommon wisdom,” says Tse. In 2010, Al-Rashid established two endowed chairs at the University of Miami, one to support Tse’s research in ophthalmic plastic, orbital surgery, and ocular oncology at Bascom Palmer; and the other to establish the Dr. Nasser Ibrahim Al-Rashid Chair in the Division of Hepatology and the UM Center for Liver Diseases.

A few years later, the Al-Rashid family made a $10 million gift to build the Dr. Nasser Ibrahim Al-Rashid Orbital Vision Research Center. The grant enabled the construction of the center, and also the recruitment of leading scientists. That support also established two endowments that will ensure scientific research is funded in perpetuity. Dr. Al-Rashid recently committed an additional $2.5 million over the next five years to the Al-Rashid Orbital Vision Research Center.

Neuroscience and the Optic Nerve

A Novel Treatment for Injury to the Optic Nerve
Orbital Vision ResearchThe optic nerve forms the connection between our eyes and our brains. Like the spinal cord, it is part of our central nervous system (CNS) and has limited capacity for repair once injured. The optic nerve is responsible for transmitting the electrical signals generated by the retina to the visual centers of the brain for decoding into what we perceive as sight. Unfortunately, several diseases and conditions can affect the optic nerve and lead to the loss of vision. Following trauma to the head for example, the optic nerve can become diseased and undergo degeneration due to traumatic optic neuropathy (TON), which ultimately leads to irreversible vision loss and blindness. Despite the high cost to a TON patient’s quality of life, there are no known treatment options that reliably improve visual outcomes. The lack of efficacious treatment is due to our poor understanding of the molecular mechanisms and pathways that contribute to the onset and progression of the disease.

The Al-Rashid Center has recently developed an animal model of TON that closely resembles the human condition without the limitations of tissue ultrastructure damage found in other animal models of optic nerve injury. This model has allowed our scientists to study indirect trauma to the nerve at the molecular level immediately following injury when disease-initiating cascades are first activated. These studies have led to the first-ever targeted treatment for Traumatic Optic Neuropathy, providing patients with the best prognosis for recovering vision. Given the highly encouraging results seen in pre-clinical testing, the Al-Rashid Center is now focusing on the establishment of a large multicenter clinical trial to gain approval of this novel therapy and make it available to all those affected by this devastating condition.

Addressing Mitochondrial Dysfunction in Neurodegenerative Conditions
Orbital Vision ResearchOne of the discovered determinants of degeneration of neurons in the visual system is mitochondrial dysfunction due to trauma or disease. The Al-Rashid center has embarked on an ambitious project of discovering novel pharmaceutical agents that can help ameliorate the mitochondrial dysfunction observed prior to the loss of nerve conductivity. We are evaluating compounds designed specifically to reduce mitochondrial oxidative stress or enhance the effectiveness of the electron transport chain on the preservation of functional vision in disease and following injury to the visual system.


Orbital Tumors and Malignancies

Next-Generation Sequencing of Adenoid Cystic Carcinoma
Orbital Vision ResearchThe Al-Rashid Center has pioneered the discovery of the mutational burden in a highly lethal tumor of the lacrimal gland, adenoid cystic carcinoma. We have identified novel mutations in this tumor type that may lead to the development of novel therapies for these patients. The Al-Rashid research team is now engaged in high-throughput screening assays of FDA-approved drugs using our in-vitro models to find the best possible combination of immunotherapy and epigenetic modulators that will allow us to more effectively kill the tumor cells while preserving normal tissues around it. In this way, we plan to pioneer a novel treatment paradigm that will save the eye, preserve vision, and save our patients' lives.

Development of the first Orbital Tumor Oncologic Toolbox
Orbital Vision ResearchIn order to better understand the lethal tumors around the eye, and find the most effective therapies to deal with them, the Al-Rashid center team has developed unique in-house tools that are used to assess the effectiveness of novel drugs and treatments. We have established the first adenoid cystic carcinoma cell lines available, with 9 cell lines currently in culture. Similarly, we have established an in-vivo animal model xenograft model for the disease, and are close to establishing the first endogenous tumor model for adenoid cystic carcinoma, an advancement that will help other cancer researchers in their fight against this type of cancer in other parts of the body. Finally, we have developed a targeted expression panel to identify particular protein profiles for individual cases that can aid in choosing the most appropriate therapies.

Discovery of Novel Adjuvant Therapeutic Targets in Adenoid Cystic Carcinoma
By studying how tumors respond to the current medical treatments designed to kill them yields powerful insights into the biological mechanisms that cancers use to resist the treatment and stay alive. We have performed studies into how adenoid cystic carcinoma responds to a novel intra-arterial chemotherapy treatment developed by Dr. Tse, and have found novel targets that we can use to augment the effect of the chemotherapy. Using a combinatorial approach, we have shown a strong synergistic effect of this adjuvant treatment in-vitro and in the pre-clinical setting, and are now designing clinical trials to move this new, more effective treatment into the standard of care for these patients.

Biomedical Engineering

Novel Biomaterials and Compounds for Nerve Regeneration
Orbital Vision ResearchRegeneration of central nervous system neurons (CNS) and neural integration of new sprouting neurites into the circuitry is a rare event. This is largely due to the fact that the mammalian CNS is riddled with repulsive stimuli to new neurite outgrowth and synaptic reconnections. By focusing on the repulsive cues that are specifically found in the inner retina and optic nerve, the Al-Rashid center has been able to develop proprietary compounds which antagonize this repulsion and promote significant new dendrite sprouting and reconnection even from mature CNS neurons. Using in-vivo models of optic neuropathic death, we were able to show that our novel compounds aid in the regeneration of axons past gliotic scars and help preserve dendritic arbors in the retina. We are now working with our Biomedical Engineering and Medicinal Chemistry collaborators to package the compounds in the most effective formulation for delivery and bioavailability. We have so far been able to introduce these compounds into nerve conduit sheaths that are used in nerve reconnection surgery, and have shown a significant improvement in nerve conductance with their use.

Developing the Next Generation of Affordable Facial and Ocular Prosthetics
Orbital Vision ResearchUnfortunately, many conditions in ophthalmology require the removal of the patient’s eye and socket tissues in order to save the patient’s life. For these patients, the resulting facial defect leaves an emotional scar far greater than the physical one, and many cannot afford the cost of a prosthesis. In the Al-Rashid Center, we have devised a way, using state-of-the-art 3D facial scanning and 3D Printing, to manufacture high-quality prosthetics that are both more affordable than the standard prosthetics offered today, and also avoid the timely procedure of mold casting and curing. We have developed this technology also with the hopes of deploying the technology around the world to countries where patients do not even have access to standard prosthetic manufacturers. To further these efforts, we have established a fundraising campaign called Save The Eye (see below).


Campaign Save The Eye - Bringing hope to patients in need of prosthetic eyes

Save The Eye is a fundraising campaign started by Dr. David Tse and Rick Arkush for the purchase of an ophthalmic 3D printer. Dr. Tse and his team will use this printer to produce financially attainable prosthetic eyes for Bascom Palmer Eye Institute patients, as well as people throughout the world who have lost an eye and cannot afford prosthetics.

There are many people who have lost an eye and then successfully moved on to fulfill their dreams. Rick Arkush is one of them. A patient of Dr. Tse’s, Arkush lost an eye due to a rare form of cancer called lacrimal gland adenoid cystic carcinoma. Rick has now made it a lifelong goal to support positive outcomes for people who have suffered from the loss of an eye or will be faced with that decision.

Stem Cells and Regenerative Ophthalmology

The next frontier in human healthcare is Regeneration. At the Al-Rashid Center, we look beyond stopping the progression of disease and have started working towards restoring function and regenerating lost tissues. In no other organ system is the concept of regeneration more impactful to the quality of life than in the eye. That is why we make use of the latest advances in Stem Cell Biology, Genetic Engineering, Epigenetics, Biomaterial Sciences, and Tissue Engineering to drive our core program on Regenerative Ophthalmology. Below are examples of some of our ongoing projects:

Lacrimal Gland Development and Regeneration
Orbital Vision ResearchDry eye disease is the leading cause of ocular morbidity worldwide and a highly prevalent disease. The condition causes permanent discomfort and pain that is only temporarily addressed by the use of lubricating eye drops. The Dr. Nasser Ibrahim Al-Rashid Orbital Vision Research Center at the Bascom Palmer Eye Institute is the world leader in the study of the lacrimal gland and the diseases affecting it. Within that context, our laboratory has achieved several milestones that are crucial for the elaboration of a lacrimal gland regeneration program. We have been able to characterize the molecular determinants behind lacrimal gland development, identified a population of progenitor cells that can be harvested for tissue engineering applications, and designed an optimal culture and biomaterial scaffold to bioengineer new gland tissues. We are now moving to the pre-clinical testing of these artificial lacrimal glands to determine their functionality and effectiveness at ameliorating dry eye conditions.

Retinal Organoid Platform for Regenerative Cell Therapies
Orbital Vision ResearchOptic neuropathies are a general set of diseases for which effective treatment remains elusive. Medical management of the optic neuropathy patient focuses on eliminating risk factors, treating symptoms, and attempting to slow down the progression of the disease. Unfortunately, and despite our best efforts, optic neuropathies invariably progress to visual loss and are one of the leading causes of irreversible blindness worldwide. However, with the advent of regenerative medicine and stem cell technologies, the concept of replacing damaged tissues to reestablish lost functionality has become a reality in many diseases such as arthritis, bone defects, and even cardiomyopathies.

In the eye, cellular replacement therapies are currently under investigation for the treatment of macular degeneration and retinitis pigmentosa. Yet, cellular therapies for neuronal replacement in the inner retina have proven to be more challenging to accomplish. Achievement of a functional regenerative therapy for optic neuropathies would signify a drastic improvement for the quality of life of millions of patients around the world. The Al-Rashid Center team seeks to overcome key technical limitations hindering the development of regenerative therapies for inner retinal neurons in a comprehensive tissue engineering approach to retinal ganglion cell regenerative therapies.

We have developed a stem cell platform that utilizes induced pluripotent stem cells differentiated into retinal organoids in the lab. These organoids help us screen drugs for unforeseen retinal toxicities, but also allow provide us with a source of new retinal neurons to be used in cellular replacement strategies. Our isolated retinal ganglion cells achieve functional maturity and express all of the correct markers for mature RGCs. We are now elaborating on the surgical procedures needed to transplant these new retinal neurons into host retinas and integrate them into the circuitry.
