The Short Answer: Certified Retinal Angiographer
On this site, CRA stands for Certified Retinal Angiographer. It is a professional certification for ophthalmic imaging specialists who perform retinal angiography, most notably fluorescein angiography (FA) and indocyanine green (ICG) angiography, along with the fundus photography and related imaging that surrounds those procedures.
The three words each carry meaning. Certified signals that a credentialing body has verified both your hands-on experience and your knowledge through a formal examination. Retinal narrows the scope to imaging of the retina and related structures of the posterior segment of the eye. Angiographer identifies the core skill: capturing images of blood flow and vascular structures in the eye after a dye is introduced.
If you have searched for related questions such as what CRA is, what the CRA abbreviation means, or what CRA certification involves, this article gives you the foundation. The rest of the page explains who issues the credential, what is tested, and what the title means for your career.
Who Awards the Credential
The Certified Retinal Angiographer credential is awarded by the Ophthalmic Photographers' Society (OPS) Board of Certification. The OPS is the professional organization for ophthalmic photographers and imaging specialists, and its Board of Certification administers the CRA program, sets eligibility rules, and publishes the program guide that defines the exam.
The controlling document is the CRA Program Guide. The current version, 15.1, is effective June 2026. Its ten weighted content areas are the official exam objectives, based on a 2017 job analysis. This matters because many candidates assume exam outlines are loose study suggestions. For the CRA, the published weights describe what the exam actually measures.
What a Retinal Angiographer Actually Does
A retinal angiographer is part photographer, part clinical technician, and part patient-care professional. The work sits between the examination room and the diagnostic reading room: the images you capture help ophthalmologists and retina specialists diagnose and monitor conditions affecting the back of the eye.
Core responsibilities
- Performing fluorescein angiography with a fundus camera or scanning laser ophthalmoscope, capturing the timed sequence of dye transit through the retinal and choroidal circulation.
- Performing ICG angiography to visualize deeper choroidal circulation.
- Capturing high-quality fundus photographs, including color and filtered images that document the retina and optic nerve.
- Acquiring monochromatic and fundus autofluorescence images that reveal structural and metabolic changes.
- Managing patients before, during, and after imaging, including consent considerations, comfort, and recognizing adverse reactions to dyes.
- Managing images and data so that results are labeled, stored, and retrievable.
Because angiography involves injecting a dye, the role carries real patient-safety responsibility. That is why pharmacology and patient/operator safety appear as formal exam content areas rather than afterthoughts.
The Ten Content Areas Behind the Title
The best way to understand what "Certified Retinal Angiographer" means in practice is to look at what the exam covers. The program guide divides content into ten weighted areas that sum to 100%. For a deeper walkthrough, see our complete guide to all 10 CRA content areas.
| Domain | Content Area | Weight |
|---|---|---|
| 1 | Applies the Principles of the Anatomy, Physiology, and Pathology of the Eye | 16% |
| 2 | Patient Management and Patient/Operator Safety | 6% |
| 3 | General Photography | 10% |
| 4 | Data and Image Management | 4% |
| 5 | Fundus Photography - Fundus Camera and Scanning Laser Ophthalmoscope | 23% |
| 6 | Monochromatic Imaging and Fundus Autofluorescence | 5% |
| 7 | Fluorescein Angiography with Fundus Camera or Scanning Laser Ophthalmoscope | 25% |
| 8 | Indocyanine Green (ICG) Angiography | 3% |
| 9 | Pharmacology | 5% |
| 10 | Other Imaging Technology | 3% |
Fluorescein Angiography (25%)
The single largest area, and the reason the credential carries "angiographer" in its name. Expect questions on procedure, timing, image interpretation of angiographic phases, and recognizing technical problems in captured sequences.
- Phases of dye transit and what each shows
- Camera and scanning laser ophthalmoscope technique
- Troubleshooting poor-quality angiograms
Fundus Photography (23%)
The second-largest area and the foundation for everything else. Fundus photography and fluorescein angiography together account for 48% of the published weights, so strength in these two areas carries much of the exam.
- Fundus camera and scanning laser ophthalmoscope operation
- Image quality, field coverage, and common artifacts
- Documenting retinal and optic nerve findings
Anatomy, Physiology, and Pathology (16%)
The clinical knowledge that lets you understand why you are capturing a particular image and what a good result should show.
- Structures of the posterior segment and their vascular supply
- Common retinal and choroidal conditions
- How pathology changes the appearance of angiographic images
The smaller areas should not be dismissed. Pharmacology (5%), Patient Management and Patient/Operator Safety (6%), and ICG angiography (3%) are compact, but they are also areas where focused review pays off quickly. Our CRA study guide shows how to sequence all ten.
How the Exam Is Built and Delivered
The CRA written examination is a computer-based test delivered at Prometric test centers. The format is straightforward:
- 175 multiple-choice questions, each with four choices and one correct or best answer.
- Two-hour time limit for the written exam under the current program guide.
- Closed book. Outside references, personal calculators, and electronics are prohibited. Scratch paper and a pencil are supplied.
- Valid government photo ID is required at check-in.
- No guessing penalty beyond the fact that incorrect or blank answers earn no credit, so answer every question.
Scoring uses a criterion-referenced standard (a Modified Angoff method) with scaled reporting. In plain terms, you are measured against a competency standard, not against other candidates. Passing candidates receive a pass notice without a numeric score, while candidates who do not pass receive a scaled score and a diagnostic report by content area. Initial results are provisional pending a 72-hour statistical verification. No current numeric cut score is publicly verified; see our CRA passing score article for what is and is not known.
For a realistic picture of difficulty and historical results, read how hard the CRA exam is and what the pass rate data shows. Historical OPS reports show 537 passes among 857 tested (63%) from 1997 to 2018, but that is a long historical span and not a current first-attempt rate.
What It Takes to Become Eligible
Unlike many certifications where you simply register and test, the CRA requires you to demonstrate practical competence before you sit for the exam. Eligibility centers on:
- An accepted applicant-produced imaging portfolio showing your own retinal imaging work.
- Verification of two years of retinal-angiography experience by your employing physician or institution.
- Current CPR, including a current in-person skills assessment.
Specified education or professional credentials can substitute for up to one year of experience. Candidates who are still completing the work-experience requirement may pursue Provisional CRA, a distinct status. There is no mandatory OPS preparation course and no universal training-hour total.
Plan your timeline carefully: submit your application and portfolio at least eight weeks before your desired examination date. Our CRA requirements guide covers eligibility in detail, and the CRA exam dates article explains scheduling.

- Teaching, eligible non-OPS-approved attendance, and publication categories are each capped at ten credits.
- Eligible non-OPS attendance earns 0.5 CEC per hour.
- Renewal costs $100 for members and $225 for non-members.
- Renewing by retesting requires the examination fee without an additional recertification fee.
Where Certified Retinal Angiographers Work
Certified Retinal Angiographers work wherever retinal disease is diagnosed and managed. Typical settings include:
- Retina specialty practices, where angiography is a daily activity.
- Ophthalmology group practices with in-house imaging.
- Academic medical centers and university eye institutes, often alongside research and clinical trials.
- Hospital eye departments and large multispecialty clinics.
- Clinical research settings, where standardized, high-quality imaging is essential.
The credential signals verified competence to employers, which can help with hiring, advancement, and credibility in specialized roles. To explore the career side, see CRA jobs, the CRA salary guide, and the analysis of whether CRA certification is worth it.
Avoiding the Acronym Mix-Up
"CRA" is a shared abbreviation. Searching the three letters alone can lead to unrelated credentials and fields. If you are researching retinal imaging, make sure every resource you rely on refers specifically to the Certified Retinal Angiographer credential from the Ophthalmic Photographers' Society Board of Certification.
A quick check: a legitimate CRA resource will mention fluorescein angiography, fundus photography, the OPS, and Prometric delivery. If a page talks about unrelated subjects, it is about a different credential and its fees, dates, and requirements do not apply to you. The pages on what CRA stands for, what CRA means, and what a CRA is all treat the term in this retinal imaging sense.
Letting the Weights Shape Your Study Plan
Knowing what CRA stands for naturally leads to the next question: how do you prepare? The published weights offer a clear roadmap. Here is one way to sequence an eight-week window so that the heaviest content gets the most time, while still leaving room for the smaller areas that are easy to overlook. Keep in mind that candidates already working in an angiography suite will find some topics familiar, so adjust accordingly.
Fundus Photography and Anatomy
- Review fundus camera and scanning laser ophthalmoscope technique (Domain 5, 23%)
- Rebuild your retinal and choroidal anatomy and pathology foundation (Domain 1, 16%)
Fluorescein Angiography
- Study dye transit phases, timing, and troubleshooting (Domain 7, 25%)
- Practice recognizing technical errors in angiogram sequences
Supporting Content Areas
- General Photography (Domain 3, 10%) and Patient Management and Safety (Domain 2, 6%)
- Pharmacology (Domain 9, 5%) and Monochromatic Imaging and Fundus Autofluorescence (Domain 6, 5%)
Small Areas and Full Review
- Data and Image Management (Domain 4), ICG Angiography (Domain 8), and Other Imaging Technology (Domain 10)
- Timed practice sets mirroring the 175-question, two-hour format
Key Takeaway
Because Fluorescein Angiography and Fundus Photography together carry 48% of the exam, weakness in either one is very costly. Master those two first, then use the remaining time to close gaps in the smaller areas. A quick-reference review like the CRA cheat sheet helps in the final days, and timed questions on the main practice test site help you adapt to the pace of 175 questions in two hours.
