Fellows are encouraged to be involved in clinical or laboratory research during the Fellowship. Each fellow must present a research project at least once during their fellowship at the department's annual Research Conference.
The Retina Service is actively involved in clinical and laboratory investigations. The Fellows have access to the Experimental Surgery Unit as well as all laboratories within the Department if arrangements are made with the appropriate supervisors of those laboratories. An EyeSi vitrectomy simulator is also available to fellows at the Veterans Affairs Hospital.
Research is usually performed within the department but can take place in another department or, occasionally, at another institution. The research interests of the faculty are varied, and many projects are in progress. Presentations of research are made annually during the Resident/Fellow Research Conference at the end of the academic year. The P.J. Leinfelder Award is given annually by a faculty committee to the fellow who has made the most significant contributions in preparing and delivering their research.

About the University of Iowa Institute for Vision Research
University of Iowa Institute for Vision Research has its own pharmaceutical grade, clinical Good Manufacturing Practice (cGMP) facility that is wholly dedicated to novel gene and stem cell therapies for humans with genetic eye diseases. The Retina Service is a regular site for major nationwide collaborative studies including:
- Gene therapy for Leber Congenital Amaurosis Trial (phase II/III sponsored by Spark Therapeutics)
- Gene therapy for exudative AMD (phase I)
- Combination anti-VEGF/PDGF therapy for wet AMD
- Combination anti-VEGF/ang-2 therapies
- Multicenter Uveitis Steroid Treatment (MUST) Trials
- Visual cycle modulator for dry AMD
- AREDS and AREDS II
- Comparisons of Age-Related Macular Degeneration Treatments Trial (CATT)
- VIEW1 (VEGF-trap)
- The Collaborative Ocular Melanoma Study (COMS)
- Choroidal Neovascularization Prevention Trial (CNVPT)
- Submacular Surgery Trials (SST)
- Complications of Age-Related Macular Degeneration Prevention Trial (CAPT)
- Protein Kinase C Inhibitor Study of Diabetic Retinopathy
- The Vitreoretinal Service has functioned as both an investigative center and as the national Photography Reading Center for the Collaborative Ocular Melanoma Study (COMS).
Research studies in large and small animals utilizing novel therapies focused on gene replacement and autologous, CRISPR-corrected stem cells are being conducted by Drs. Elliott Sohn, Steve Russell, and Ed Stone at the UI Institute for Vision Research.
Faculty and Research Areas of Interest
Michael D. Abramoff, MD, PhD
Research Areas of Interest
- Develop novel methods for computer aided diagnosis and image analysis - combining clinical ophthalmology, visual neuroscience, and bioinformatics to study the phenotypes and genotypes of these diseases.
- Our team has developed image analysis algorithms that simulate visual processing by the human brain to improve existing image analysis techniques. We are starting to test the image processing algorithms on larger groups of patients collected through our retinal imaging networks.
- We aim to make computer-aided diagnosis and digital retinal imaging for the screening, diagnosis and measurement of diabetic retinopathy, age related macular degeneration and glaucoma, patient friendly, low-cost and effective.
