Pediatric Ophthalmology and Adult Strabismus


This fellowship program provides broad exposure to both medical and surgical treatment of pediatric eye conditions and adult strabismus. The Zanvyl Krieger Children’s Eye Center at the Wilmer Eye Institute is a tertiary referral center where clinical fellows enjoy well-rounded exposure to both the clinical and academic sides of pediatric ophthalmology and adult strabismus. We are privileged to have our pediatric and adult facilities combined in a unified, modern, and child-friendly center, providing excellent exposure to a wide variety of pediatric eye diseases as well as to strabismus in adults.

We have trained over 65 clinical fellows in pediatric ophthalmology and adult strabismus since 1979. They have come from a wide cross-section of residency programs, both from the United States and abroad, and a few have come from private practice to start a new career. About 40% are now in private practice, with the other 60% in academic positions, including five full professors and six department chairs.

Program Overview

Fellowship here is stimulating and enjoyable in a supportive atmosphere that we experienced ourselves during a most productive time of our own careers. One-on-one contact with faculty - learning, operating, and teaching in the field of pediatric ophthalmology and adult strabismus takes place within a full-service ophthalmology department. The division has five full-time clinical faculty, two full-time Ph.D. investigators, and two orthoptists. Our fellows can take advantage of continued exposure to world-renowned ophthalmologists in all ophthalmic subspecialties, via lectures and weekly Grand Rounds.


We encourage academic pursuits during the fellowship year. We host departmental Grand Rounds four times each year and have at least six Pediatric Ophthalmology Journal Club evening meetings each year. We also have a year-long pediatric ophthalmology didactic curriculum that is held monthly on Thursday evenings.  The curriculum covers Taylor’s pediatric ophthalmology textbook, landmark articles from the pediatric ophthalmology literature, and noteworthy new studies. Our faculty also conduct surgical skills training sessions in strabismus and anterior segment surgery for both fellows and residents.


The fellow will gain excellent experience in a wide variety of strabismus surgery, with exposure to hang-back surgery, cyclovertical surgery, and adjustable sutures in both children and adults. In addition, experience is gained in congenital cataract surgery, nasolacrimal disorders, and ROP screening and treatment.

Below are the surgical numbers for our fellows during the 2015-16 year:

ProcedurePrimary Surgeon Assistant
Horizontal strabismus227166
Vertical strabismus2210
Inferior oblique2810
Superior oblique158
Adjustable sutures15675
CE w/o IOL25
ROP laser8x
Nasolacrimal procedures (probe/stent/balloon)6x
Glaucoma tube shunt32


An average of one-half day per week is available for research. This can be either on projects of your own choosing or one of the many projects being conducted by our faculty. We encourage fellows to submit their research to AAPOS, ARVO, and/or AAO.

We provide a PGY-5 stipend for each of our fellows (plus fringe benefits, including individual health insurance). The stipend is supported in part by the Judith and Paul Romano "Binocular Vision and Strabismus" Fellowship Endowment Fund, as well as by endowment income from gifts from Dr. Stewart M. Wolff. To help defray part of this expense, the department requires accepted fellows to apply to sources of outside funding when applicable, such as the Heed Ophthalmic Foundation, which provides partial fellowship support to U.S. applicants.

To Apply

The 2018-2019 fellowship application cycle has closed. The application deadline for 2019-2020 is September 2018.

Fellowship start date: July 1, 2019, with a few days allowance for relocating as necessary.

Interviews: We invite promising applicants to an interview at Johns Hopkins, which will be necessary for further consideration. We are sometimes able to interview international applicants at the Annual Meeting of the American Academy of Ophthalmology.

All applications will be submitted centrally to the SF Match site. Please refer to the SFMatch website to register for the match and read about the process for applying to Ophthalmology Fellowship training. Once registered you can view our program listing on the SFMatch directory Web site for all required documents.

U.S.-trained residents apply for and upon receipt of a Maryland medical license, they will be appointed as junior faculty at the Wilmer Eye Institute. 

Applications from other countries are encouraged, particularly from applicants seeking to return to an academic training program in their home country. International fellowship applicants are not required to have a medical license, but they must have passed Steps 1 and 2 of the USMLE exams ( and have a valid Standard ECFMG Certificate ( for graduate medical education in the United States. Unlike requirements for residency training programs, Step 3 of the USMLE is not needed for fellowship training.  

All Fellows, whether from U.S. or international residency programs, receive the same fellowship experience with the same responsibilities.

Faculty Focus

pediatric ophthalmology fellowship facultyPediatric fellowship faculty (L to R): David L. Guyton, M.D., Alex Christoff, C.O., Courtney Kraus, M.D., Megan Collins, M.D., M.P.H., Michael X. Repka, M.D., M.B.A.

Dr. David Guyton is the Zanvyl Krieger Professor of Pediatric Ophthalmology. His primary interests are in complicated strabismus, ophthalmic optics and ophthalmic instrumentation (currently vision screening devices). Time spent with Dr. Guyton will be mostly in strabismus, with a mix of pediatric and adult cases. Adult strabismus cases, comprising approximately 75% of Dr. Guyton’s practice, provide the fellow a unique opportunity to become familiar with more advanced diagnostic and treatment modalities in strabismus. Adult strabismus is more surgically focused than pediatric strabismus because of less long-term follow-up needed. Exposure to adult strabismus cases allows the fellow to become comfortable and familiar with surgical techniques needed for re-operations, as well as crucial diagnostic techniques. More subtle problems that are not always easily appreciated in children, such as those of torsional and vertical strabismus, are magnified in adults, and mastery of management techniques in such situations allows for optimal treatment to be applied to all age groups.

Dr. Michael Repka is the David L. Guyton, M.D., and Feduniak Family Professor of Ophthalmology. He joined Wilmer in 1985 and currently serves as the chief of the division of pediatric ophthalmology and adult strabismus and the Vice Chair for Clinical Practice at Wilmer. He is nationally and internationally known for his contributions in the fields of pediatric ophthalmology, strabismus, retinopathy of prematurity, and pediatric neuro-ophthalmology. Time spent with Dr. Repka will provide exposure to all of these areas.

Dr. Megan Collins is the Fellowship Director. She provides comprehensive care to pediatric patients and performs surgery for adult and pediatric strabismus. Dr. Collins also sees patients with vascular anomalies and craniofacial malformations, as part of the Hopkins craniofacial team.

Dr. Courtney Kraus specializes in pediatric ophthalmology and adult strabismus, with particular interest in pediatric cataracts and corneal diseases. Surgical experience with Dr. Kraus will include pediatric cataracts with and without primary IOL implantation, secondary IOLs and IOL exchanges, and specialty lenses. In addition, she provides medical and surgical care of glaucoma, ptosis, and nasolacrimal duct disorders.
