Once the components of the POAG material are identified, Dr. Pattabiraman’s team will compare POAG patients with age-matched, non-affected subjects, leading to a better understanding of the underlying mechanism of the material’s formation.
Jessica M. Skeie, PhD, Carver College of Medicine Award: $15,611
Dr. Skeie, an Assistant Research Scientist/Engineer at the Carver College of Medicine in Iowa, will investigate the metabolic optimization of endothelial keratoplasty graft tissue preparation, as she tries to determine if the viability of corneal transplant tissue can be improved by treating it with antioxidant molecules before surgery. The implications of Dr. Skeie’s research on partial-thickness corneal transplantation could be significant. Demand is increasing for eye banks like Eversight to prepare partial-thickness tissue grafts, which replace a patient’s affected corneal endothelium, the inner lining responsible for maintaining a clear cornea. But approximately one third of the cells in a partial-thickness cornea transplant do not survive the first six months after surgery, and that can lead to a loss of corneal clarity. Dr. Skeie and her team will test whether donor endothelial cells exposed to antioxidant molecules can improve cell viability following tissue preparation for partial-thickness transplants. The research is also intended to help improve the understanding of the mechanisms involved in corneal endothelial cell health, and how to reduce or eliminate adverse effects on transplant tissue.
K.P. Connie Tam, PhD, Cleveland Clinic Lerner College of Medicine Award: $20,000
Dr. Tam, an Assistant Professor of Ophthalmology at the Cleveland Clinic Lerner College of Medicine, will investigate whether antibacterial eye drops can help prevent or reduce the severity of the disease caused by Pseudomonas aeruginosa, a major bacterial pathogen, which can lead to serious eye infections. The implications of Dr. Tam’s project could lead to better optimization of the use of keratin antimicrobial eye drops, resulting in novel anti-infective therapeutics for combating infections of the cornea and other sites.
Sarah Wood, OD, MS, University of Michigan Kellogg Eye Center Award: $15,000
Dr. Wood, a Clinical Instructor of Ophthalmology and Visual Sciences at the Kellogg Eye Center, will study a new treatment called Intense Pulsed Light (IPL) for the treatment of dry eye disease, which often causes debilitating inflammation of the eyes and is suspected of compromising surgical outcomes and patient satisfaction following cataract and refractive surgery and corneal transplantation. Additional studies are critical to a better understanding of the potential for IPL to minimize objective measures of dry eyes and improve patient quality of life.
Charles Yu, MD, University of Illinois Eye and Ear Infirmary Award: $15,000
Dr. Yu, an Assistant Professor of Ophthalmology at the University of Illinois Eye and Ear Infirmary in Chicago, is working to develop an advanced artificial cornea, a keratoprosthesis, often used when a corneal transplant is not possible because of a prior rejection, or excessive ocular damage. Currently, a keratoprosthesis operation requires a three-piece plastic device sandwiched around a donor cornea and sutured into the eye of the patient. While it offers short term visual improvements, patients often lose vision due to complications like membrane formation around the device. Dr. Yu’s one-piece keratoprosthesis requires a smaller incision resulting in faster patient recovery and does not require the use of donor tissue like existing devices. If successful, this artificial cornea could become available for human clinical trials and eventually be used for curing corneal blindness.
