A link between fetal light exposure and retinopathy of prematurity
In a multidisciplinary collaboration between basic scientists and clinicians, members of Pediatric Ophthalmology showed that light exposure during pregnancy is a risk factor for severe retinopathy of prematurity. A study published in Nature in February 2013 by researchers in the laboratory of Richard Lang, PhD, and David Copenhagen, PhD, University of California, San Francisco, first showed that a light response in the fetal eye of mice regulates the number of retinal neurons and, in turn, the pattern of retinal vascularization. Taking his cue from this biology, Michael Yang, MD, published an analysis in Ophthalmology that shows reduced light exposure during the first trimester is strongly associated with severe forms of retinopathy of prematurity. These finding may suggest that many cases of retinopathy of prematurity could be prevented if newly pregnant mothers received sufficient daily light exposure.
Eye Genetics Clinic Launched
In October 2012, Pediatric Ophthalmology and Human Genetics established a joint clinic to evaluate and diagnose patients with rare and novel genetic eye disorders. The clinic evaluation and diagnosis side is led by Constance West, MD, Director of Pediatric Ophthalmology, and Howard Saal, MD, Director of Clinical Genetics and Cytogenetics. They are assisted by Virginia Utz, MD, and Robert Hufnagel, MD, PhD. Additional staff includes fellows, residents, genetic counselors, and research coordinators. So far, the Eye Genetics Clinic has provided formal evaluations for more than 20 families. Patients are evaluated by ocular examination, modern imaging, color vision analysis, electrophysiology and clinical genetic testing. The genetic research aspect of the clinic is led by Zubair Ahmed, PhD, Associate Professor of Pediatric Ophthalmology and Human Genetics. With the goal of describing novel diseases and uncovering new disease genes, 70 individuals have been enrolled in Ahmed’s research. Identification of novel disease genes will provide new questions for research in animal model systems, to be answered in research labs of the Visual Systems Group led by Richard Lang, PhD. The group studies the mechanisms of familial ocular disease to identify therapeutic targets and test novel treatments.
Zubair Ahmed, PhD
Zubair Ahmed’s lab continued to investigate the molecular and genetic basis of Usher syndrome and oculocutaneous albinism (OCA) by utilizing human, mouse and zebrafish genetics. In collaboration with the Human Genetic Division, Dr. Ahmed’s lab and Ophthalmology Division clinicians have established a specialized EyeGenetic Clinic at Cincinnati Children’s to provide contemporary clinical and genetic diagnostic facilities. In the past year, work from Dr. Ahmed’s lab was presented at the Association for Research in Otolaryngology (ARO) annual meeting and the Gordon Research Conference (GRC) on Auditory Systems.
Tiffany Cook, PhD
Dr. Cook’s research continues to explore evolutionarily conserved processes underlying retina and lens formation. Her group has made important advances in understanding into how the decision to become neuronal (retina) vs. non-neuronal (lens) is made during development. In addition, Dr. Cook’s retina research has provided mechanistic insight into how the various light-sensing photoreceptor cells are generated and maintained. This work has implications for developing better diagnostic and therapeutic tools for retinal degenerative diseases. Last year, Dr. Cook presented her work at the University of Georgia, the University of Kentucky, and members of her laboratory received awards at the Association for Research in Vision & Ophthalmology Annual Conferences, and the Midwest Society for Developmental Biology Meeting.
Fumika Hamada, PhD
Dr. Hamada’s laboratory studies circadian rhythm of body temperature (body temperature rhythm). Body temperature rhythm is critical for the maintenance of homeostasis functions, such as metabolic energy generation and sleep. Her lab progress has been remarkable as their work reveals the hitherto unknown molecular mechanisms underlying body temperature rhythm and has led to the first identification of a molecule that links circadian clock to body temperature rhythm. Dr. Hamada has presented her work at Cold Spring Harbor, Janelia Farm and SRBR (The Society for Research on Biological Rhythms) meeting.
Sarah Lopper, OD
Dr. Lopper is a Team Member of the Uveitis Task Force with the Division of Rheumatology. This task force has been working on various educational tools and a reporting system for area eye care providers. They recently published the updated “Best evidence statement (BESt) for Screening for uveitis in children with juvenile idiopathic arthritis (JIA)” in the National Guideline Clearinghouse (an agency of the US Department of Health & Human Services that is an online resource for evidence-based clinical practice guidelines). She is also part of the clinical team that is working on the Divisional outcomes goal for Juvenile Idiopathic Arthritis (JIA) disease and the percentage of JIA patients without active uveitis. Dr. Lopper is a volunteer clinician at the Cincinnati Association for the Blind and Visually Impaired. Her current research includes examining the interactions of visual characteristics of school-aged visually impaired children, validating a functional low vision clinic model and describing predictors for success with reading in these children.
Kelly E. Lusk, PhD, CLVT
Dr. Lusk is the Director of Education and Research for the Cincinnati Children’s Vision Rehabilitation Program (CCVRP), a clinical low vision service delivery program serving children (ages 3-22) with low vision. Current collaborative efforts in research within Cincinnati Children’s include the Aaron W. Perlman Center, the Division of Neonatology and Pulmonary Biology, and the Pediatric Neuroimaging Research Consortium.
W. Walker Motley, MS, MD
Dr. Motley is the Director of the Cincinnati Children’s Clinical Fellowship in Pediatric Ophthalmology and Adult Strabismus. Dr. Motley has continued his work in improving physician education in Cincinnati-based collaboration with pediatric eye surgeons in nine countries. Dr. Motley’s co-authored two peer-reviewed publications in the area eye surgery training. Dr. Motley also continued clinical research on eye disease affecting individual with Down syndrome and other developmental disabilities. Dr. Motley was elected to serve as the Secretary-Treasurer of the Ohio Ophthalmological Society. Dr. Motley was selected to participate in the competitive Leadership Development Program of the American Academy of Ophthalmology.
Michael B. Yang, MD
Dr. Yang's research focus is on retinopathy of prematurity (ROP). His recent clinical research suggested an association between length of day during early gestation (i.e. season of conception) and the subsequent development of ROP during late gestation in premature infants. This work, performed in collaboration with Dr. Lang and colleagues, complements Dr. Lang's findings on the effect of light and melanopsin on vascular development in the eyes of fetal mice and was presented at two national meetings this past year. Under Dr. Yang's leadership, the division has also begun data collection for the G-ROP (Growth for ROP) Multicenter Study which evaluates weekly weight gain after birth in premature infants as a predictor of ROP outcome. The goal of the G-ROP study is to develop a highly accurate model of ROP outcome that allows a reduction in the number of screening eye examinations that have to be performed on premature infants to detect the small number of infants who develop severe ROP. As a member of the Ophthalmic Technology Assessment Committee of the American Academy of Ophthalmology, Dr. Yang co-authored a paper assessing the accuracy of rebound tonometry for the measurement of intraocular pressure.

Alterations of the CIB2 calcium- and integrin-binding protein cause Usher syndrome type 1J and nonsyndromic deafness DFNB48. Nat Genet. 2012; 44:1265-71
- This study describes the identification of a novel gene (CIB2; calcium and integrin binding protein 2) causing autosomal recessive non-syndromic hearing impairment as well as the Usher syndrome 1J (USH1J). Causative mutations in the CIB2 were found in 56 families segregating non-syndromic deafness (DFNB48). Moreover a causative CIB2 mutation was present in one family segregating Usher syndrome (USH1J). This study provides genetic and functional data from human, wild type mouse, zebrafish and Drosophila CIB2 orthologs. Taken together our genetic and functional studies indicate that CIB2 is essential for the development, maintenance and normal receptor potential currents of sensory hair cells and for the photoreceptor function.

- In this study, we uncovered a light response pathway in the fetal eye. This pathway uses the atypical opsin melanopsin to regulate and number of neurons that develop and ultimately, the pattern of vascular development in the eye. An unusual feature of this response is that it occurs while the fetus is still gestating and relies on light that passes through the body wall of the mother. Though this study was performed using mice, it is likely that this same pathway is important for human fetal development.
