The Division of Ophthalmology at the Cook County Health offers medical and surgical ophthalmic care to adults and children with diseases and injuries of the eye, orbit and eyelids.

Common diseases that affect the eye include diabetes, glaucoma and cataracts, but in addition, comprehensive care is offered to patients suffering from a broad spectrum of common and rare eye conditions ranging from eye disease due to premature birth to severe traumatic injury in adults.
Each year, the division treats 50,000 patients, performing over 2,300 major ocular surgeries, 10,000 intraocular injections and over 2,000 laser procedures. This is in addition to routine medical management of ophthalmic disease, as well as countless numbers of minor procedures. The Division of Ophthalmology is the busiest unit under the Department of Surgery.
Clinic services include fluorescein angiograms, visual field testing, ultrasound imaging, corneal hysteresis, ocular coherence tomography and nerve fiber layer analysis. The physicians utilize many methods of sophisticated care options, and many eye diseases can be treated with medical, surgical or laser procedures.
The Ophthalmology clinic, located in the Professional Building, is a comprehensively equipped facility with specialists available in seven subspecialties including: medical/surgical retina, oculoplastics, cornea, glaucoma, uveitis, pediatrics/strabismus and neuro-ophthalmology.
Minor surgery procedures can be performed within the clinic and the vast majority of major surgical procedures are performed on an outpatient basis using “same-day” surgery in the Hospital.

      Residency Program

      The ophthalmology residency training program at Cook County Health is fully accredited by the Accreditation Council on Graduate Medical Education (ACGME), and approved by the American Board of Ophthalmology.
      The goal of the residency is to develop skilled practicing comprehensive ophthalmologists and subspecialists by providing extensive clinical and surgical experience over a four-year period.
      The program accepts four residents per year and participates in the central application service (CAS) of the San Francisco Matching Program. Admission is contingent upon the successful completion of an ACGME accredited or Canadian-approved internship.
      All major subspecialties in ophthalmology are represented in the division with respect to clinical experience and faculty involvement. These include the following:


      The PGY-1 residency positions were integrated into the program July 2021 providing our residents with a comprehensive experience prior to beginning their formal ophthalmology training. The first year begins with a two-week orientation in which subspecialty attendings give introductory lectures and provide hands-on instruction in use of ophthalmic equipment and refraction. Rotations consist of two-, four- and six- week rotations in a variety of specialties, including internal medicine, plastics, dermatology and ophthalmology. During their ophthalmology rotation, residents will participate in general clinic, as well as train in ophthalmic imaging, testing and refraction.
      During the second year, residents become integrated into Stroger Hospital Eye Clinic, as well as at our satellite clinic at Provident Hospital. At Provident Hospital, residents attend biweekly clinics for three months during the year where they experience their initial exposure into the operating room, as well as individualized attention with anterior segment and retina subspecialty attendings. Meanwhile at Stroger Hospital, there are three three-month rotations in general clinic where residents learn to assume increasing responsibility in managing patients. Residents also participate in oculoplastics rotations where residents serve as primary surgeons in minor procedures, as well as participate in oculoplastic clinical evaluations and a pediatrics rotation where residents have weekly first-hand experience in strabismus surgeries. First-year residents also perform anterior segment laser and retina laser procedures and intravitreal injections as proficiency allows.
      The third-year resident schedule is divided into four blocks. During the three months of the consult rotation, the resident is responsible for treating both outpatient and inpatient consults. The consult resident also gains exposure to pediatric ophthalmology and retinopathy of prematurity screening during this rotation block. The retina rotation comprises a second block, where residents are exposed to extensive retinal pathology. This block provides residents with an opportunity to gain proficiency in intravitreal injections and retinal laser procedures. A third block consists of three months at the Blue Island Health Center Eye Clinic, which is staffed by Stroger Hospital Ophthalmology faculty. During this rotation, a second-year resident is introduced to major intraoperative procedures, including cataract surgery. The resident performs 20 to 30 cataract surgeries as the primary surgeon during the Blue Island rotation. A fourth block is spent as chief of the comprehensive Eye Clinic. There is one morning per week devoted to ophthalmic pathology under the guidance of our ocular pathologist, Dr. Bamba where residents gross in ophthalmic specimens and review previous slides at the microscope.
      The major focus of the fourth-year resident is performing surgical procedures. More than 2,300 major operative eye cases are performed each year. The senior resident performs all surgical cases. All major surgery is supervised by attending physicians. Starting in 2017, a new rotation at Provident Hospital, another Cook County Health affiliate, has been established. Stroger Hospital Ophthalmology faculty also staff Provident Hospital. This rotation will allow for three days weekly in the operating room with further emphasis on expanding residents surgical skills. Senior residents are also responsible for aiding in patient care, and overseeing junior residents and medical student education in the general eye clinic. One senior resident is selected yearly to function as Chief Resident with administrative and educational responsibilities.


      Subspecialty attendings conduct teaching conferences daily in which material in the Ophthalmology Basic and Clinical Science Course (BCSC), published by the American Academy of Ophthalmology (AAO), is systematically covered. 
      The BCSC books are provided to each resident at the start of their first year. Monday mornings are devoted to Morning Report to review on-call issues and discuss cases. Every morning thereafter, lectures are held where attendings presents on high yield topics within their subspecialty. Grand Rounds are held each semester and formal Journal Club is held on a quarterly basis. Prior to the annual in-service examination (OKAPs) in March, a three-day comprehensive review of all BCSC topics is held at Stroger Hospital and is open to all Chicago-area residency programs at no cost. 

      In addition to the comprehensive in-house academic program, residents can participate in citywide combined educational programs. The first of these is the Chicago Curriculum in Ophthalmology (CCO), which is a lecture series with faculty from all six Chicago area residency programs participating. Lectures are held from September through April on Saturday mornings. Stroger Hospital Ophthalmology residents also attend the Chicago Ophthalmological Society (COS) monthly meetings free of charge. These meetings are held monthly on Monday evenings at the University of Chicago Gleacher Center from September through April. Nationally known speakers from all ophthalmic specialties are invited to give talks at this excellent forum.

      All Cook County Health Ophthalmology residents have full privileges at the Stroger Hospital Tice Library and the Rush University’s Medical Library.

      All residents are required to participate in at least one research project during their residency. The research project should lead to completion of a structured abstract for paper or poster presentation or a manuscript suitable for submission.
