RESEARCH ACTIVITIES

Dana Center faculty have continued to carry out major research related to public health ophthalmology, to publish those findings, and to train a wide range of students in this work.

Trachoma

Trachoma is still the leading infectious cause of blindness worldwide and Dana Center faculty have led trachoma control programs for nearly three decades. We have carried out clinical trials in Tanzania, Ethiopia and Niger and in collaboration with the World Health Organization; we have conducted research on all facets of the SAFE strategy. We continue to provide technical assistance to partners and countries about trachoma control. Current research in Tanzania is investigating approaches to reduce infection and disease in communities, and to better screen and treat trichiasis in adults. We are partnering in the development of alternative diagnostic/surveillance tools for trachoma control with studies in Tanzanian and Nepal. Most recently, we have a new clinical trial to determine the added benefit for communities with low levels of C. trachomatis infection of a program to identify and treat new families who arrive after mass treatment, and travelers who leave and may bring back trachoma, as they could be an important source of re-infection.

We have studies in Tanzania on improved screening methodologies for identifying trichiasis cases and getting them to surgery. We continue to explore methods for improving trichiasis surgery outcomes in developing countries. Dana Center faculty are part of a cooperative agreement with PAHO, and sit on the technical expert committee of International Trachoma Initiative, and the Special Technical Advisory Group for Neglected Tropical Diseases for WHO.

Diabetic Retinopathy

To address the fact that nearly half of adults with diabetes do not have their eyes screened on an annual basis, we carried out research on an opportunistic model to screen individuals with diabetes in pharmacies. This effort faced logistical obstacles and we instead shifted our work to charity hospitals where screening efficiency was found to be substantially higher. This work, funded by the Centers for Disease Control, is ongoing and manuscripts have been submitted.

In addition, in collaboration with Helen Keller International, we have been developing and expanding diabetic retinopathy screening programs in Bangladesh and Indonesia. Both programs are now established and the Indonesia program has been expanded to community health centers where even more of the at risk population can be screened. Furthermore, we recently completed a trial (funded by Sightsavers International) assessing strategies to improve patient follow-up after screening. With the implementation of better educational programs and closer monitoring the Chittagong screening program was able to achieve nearly 80% follow up of patients who screened positive for diabetic retinopathy.

Dana Center faculty continue their collaboration with researchers in England to develop an online system for training and evaluation for fundus image grading centers. This is a core activity that will be needed to sustain these burgeoning programs.

Glaucoma

Dana Center faculty continue to work on imaging techniques that will help distinguish those with angle closure glaucoma from those without the condition. Recent investigations include the development of automated algorithms for classifying the angle status of individuals using OCT. We also have assessed novel components of angle closure including iris and choroidal volume change. This work is being conducted at Hopkins as well as in China, Singapore, and India.

We have recently completed a study with investigators at the Aravind Eye Institute in India and found that family members of angle closure glaucoma patients have a much higher risk of angle closure glaucoma. This finding may lead to improved screening recommendations for angle closure disease. We also are examining the genetic basis of angle closure glaucoma in this population to identify new potential targets for disease treatment.

Finally, we have an ongoing large clinical trial underway in Guangzhou, China to determine if laser iridotomy is beneficial for treating individuals with narrow angles. This study has enrolled over 800 people after screening more than 10,000 and is in its 4th year of follow-up with over 90% remaining in the study. Results from this trial will guide the treatment of angle closure throughout the world.

Cataract and Refractive Error

The Dana Center is working closely with Aravind Eye Institute to develop new models for increasing cataract surgical quality and volume in Africa. This work, funded by the Hilton Foundation, focuses on partnering with existing eyecare programs to help them improve their service delivery and ultimately to dramatically increase the volumes of surgery performed. The Dana Center is documenting the baseline condition at these institutions, the inputs of the program, and the overall outcomes. This approach was developed under the leadership of Alfred Sommer and in collaboration with leaders in African ophthalmology. So far five hospitals are participating and after one year dramatic changes are already taking place.

Dana Center faculty in collaboration with Helen Keller International, continue to support expansion of cataract surgical training using novel methods in south China. Access to qualified clinicians who are capable of providing high-quality cataract surgical care remains a significant problem in China. Most of the cataract surgeons practicing in remote rural Chinese communities do not have the requisite skills and equipment needed to ensure good visual outcomes. We continue to support surgical training and outreach programs using a unique approach in which surgeons are trained in their local hospitals by expert trainers. Furthermore, we have carried out several operational research projects to determine the factors that determine who does and does not receive an eye exam and how best to encourage patients who need surgery to take advantage of the services being offered.

Also in collaboration with HKI, Dana Center faculty support the expansion of refractive services in China, Indonesia and Vietnam. We have shown that when carrying out school-based activities it is important to screen teachers as well because they frequently need glasses. Our faculty have completed clinical trials to document the effectiveness of the provision of ready-made spectacles and continue to publish data from this work.

Finally, Dana Center faculty recently started a study of reading and vision in school children. This study will determine if vision factors as opposed to dyslexia help to explain why some children read poorly. This study will enroll 400 second graders, administer standardized reading and vision tests, provide


Page 3

glasses as needed, and then re-evaluate children at 6 months for change in reading ability. If some poor readers benefit from spectacles, magnification or other interventions, then we will pursue a larger clinical trial to develop an approach that could be used widely in young children to improve overall school performance.

Vision Loss and Function

A major focus of the Dana Center is to determine the magnitude of the problem of vision impairment and to publicize our findings to help advocate for eyecare services to be provided to the populations who need them. In the recent past we published a lead article in the Journal of the American Medical Association (JAMA) on the prevalence of vision loss in the United States using data collected during the National Health and Nutrition Examination Survey (NHANES). Dana Center faculty are also assessing the impact of vision loss using population-based data (the Salisbury Eye Evaluation project) as well as data collected on patients cared for at the Wilmer Eye Institute. A particular emphasis has been placed on “real-world” measures of disability, such as testing of physical activity in the normal routine through the use of accelerometers, assessing travel outside the home using remote tracking devices, and testing of book reading through a validated test of sustained silent reading. We have continued to expand this work and recently completed the recruitment for a prospective cohort study of Falls in Glaucoma (FIGS) which is funded by the NIH. This 5-year grant will determine what factors lead glaucoma patients to fall at much higher rates than those without glaucoma and will help in developing to interventions to prevent falling and disability in these patients.

Retinal Degenerations

The Dana Center faculty run the Data Coordinating Center for a series of studies on Stargardt’s diseases, determining the risk of progression using a variety of outcome measures. We are also the Data Coordinating Center for a clinical trial of nutrition supplements in patients with ocular albinism.

Large Database Analysis

The Dana Center faculty are continuing their long tradition of health services research. Using the Medicare billing database we have documented the volume of glaucoma care being delivered, types of interventions and tests performed, their change over 2002-2009, and the cost of treatment. We also have used NHANES to identify what factors are associated with not being screened for diabetic retinopathy, and have just completed using the same database (with additional grading of optic nerve images) to analyze glaucoma prevalence and associations as well as eyecare utilization among persons with glaucoma. These manuscripts are in submission.

Harry A. Quigley, MD

Maumenee Professor of Ophthalmology

Director, Glaucoma Service

Dr. Quigley was born in St. Louis and is a graduate of Harvard College and Johns Hopkins Medical School (Alpha Omega Alpha). After ophthalmic residency at the Wilmer Institute, he did a fellowship with Douglas Anderson at the Bascom Palmer Eye Institute, Miami. He became the A. Edward Maumenee Professor of Ophthalmology in 1994, directing the Glaucoma Center of Excellence and for 20 years was director of the Dana Center for Preventive Ophthalmology at Wilmer. He was a founding member of the American Glaucoma Society, serving for 8 years as its Secretary. He was elected to 5 year terms as chief executive officer of the Association for Research in Vision and Ophthalmology (ARVO) and Editor-in-Chief of Investigative Ophthalmology and Visual Science. He has published over 350 peer-reviewed articles, and his reports are the most cited in the ophthalmic literature over the last 30 years (Archives of Ophthalmology, 2007). He has been honored with the Friedenwald Award by ARVO, the Doyne Medal by the Oxford Ophthalmological Congress, the Leslie Dana Medal by the St. Louis Society for the Blind, and by research awards from Research to Prevent Blindness, the Alcon Research Award (twice), the European Society of Ophthalmology (Prix Jules Francois), the Chicago Ophthalmological Society (best teacher), Ophthalmological Society of Scotland (Mackenzie Medal), Australian Society of Ophthalmology (Gregg Medal), Irish Ophthalmological Society (Mooney Medal), and the New York Academy of Sciences (Lewis Rudin Prize). He is a Gold Fellow of ARVO, a recipient of the Secretariat Award of the American Academy of Ophthalmology. He has given 35 named lectures, including the 66th Edward Jackson Lecture (American Academy of Ophthalmology). Dr. Quigley has trained 55 glaucoma clinician--scientists who practice in the U.S. and worldwide. His research has improved the early diagnosis of glaucoma and has developed instruments and techniques to identify glaucoma damage better including a suturing technique for trabeculectomy that has been widely adopted. His investigations demonstrated the degree of glaucoma damage that precedes present detection methods. He was the first to report on long-term success with laser iridotomy.

He has participated in pioneering studies of the epidemiology, morbidity and progression rate of glaucoma and other eye disease in American, African, Asian, and Hispanic populations, serving as a consultant to the World Health Organization. He conceptualized new roles for iris and choroidal volume change as risk factors in angle closure glaucoma. In the laboratory, he has demonstrated successful gene therapy to protect retinal ganglion cells from experimental glaucoma, and developed glaucoma models in monkeys, rats and mice.

Shannath Merbs, MD, PhD Associate Professor of Ophthalmology

Shannath L. Merbs, M.D., Ph.D., FACS is an Associate Professor of Ophthalmology at the Wilmer Eye Institute and an Associate Professor of Oncology in The Johns Hopkins University School of Medicine. She is the current Executive the Secretary of the American Society of Ophthalmic Plastic and Reconstructive Surgery and is the director of the ASOPRS fellowship program for the Wilmer Eye Institute. Dr. Merbs recently completed the Leadership Development Program through the American Academy of Ophthalmology. In addition to her NIH-funded basic science research on the role that epigenetics and DNA methylation play in retinal development and disease, Dr. Merbs is also actively involved in research to improve the outcome of surgery for trachomatous trichiasis, the leading infectious cause of blindness worldwide. With colleague Dr. Emily Gower, Dr. Merbs developed a new surgical instrument called the TT clamp to aid non-physician surgical technicians who perform the surgery. She was a co-investigator in a clinical trial in Tanzania to test the outcome of surgery using the TT clamp vs the standard instrumentation that was funded by the Bill and Melinda Gates Foundation. Dr. Merbs is also the lead author of the new edition of the World Health Organization manual for trichiasis surgery. Dr. Merbs was invited by the Colombian Ministry of Health and the Pan American Health Organization to lead a national training program for trachomatous trichiasis surgery in Mitu, Colombia, a small town located in Southeastern Colombia in the Amazon Basin only accessible by river or plane. Trachoma has recently been identified in the local population that lives in the rainforest there. She taught surgeons from Bogota how to do trachoma surgery and as a group they operated on about 30 patients with severe disease. In June, she went back to Mitu assess the individuals who had received surgery the year before and taught a new set of surgeons. A manuscript on the potential importance of incision height in the surgery was recently accepted and might eventually lead to changing the way the surgery is done throughout the world.
