What You Are Actually Studying For
The Certified Retinal Angiographer credential is awarded by the Board of Certification of the Ophthalmic Photographers' Society (OPS). It certifies that an ophthalmic photographer can perform retinal angiography and related fundus imaging safely and competently. If you are still orienting yourself, what CRA certification is and what the CRA acronym stands for are covered separately. This guide assumes you have decided to sit for the exam and want a plan that works.
The controlling document for everything below is the OPS CRA Program Guide (version 15.1, effective June 2026). Its ten weighted content areas are official exam objectives based on the 2017 job analysis, not a suggested curriculum. That distinction matters: every domain is fair game, and the weights tell you roughly how many of your 175 questions come from each.
Exam Format and Logistics
The written exam is delivered as a computer-based test at Prometric test centers. No current remote or adaptive delivery option is verified, so plan around a physical testing site and its availability. For scheduling windows and deadlines, see our CRA exam dates guide.
| Element | What the Program Guide Says |
|---|---|
| Questions | 175 multiple-choice; four choices, one correct or best answer |
| Time limit | Two hours |
| Scored vs. unscored items | Split not separately disclosed |
| Guessing | No extra penalty; incorrect or blank answers simply earn no credit |
| Reference materials | Closed book; outside references, personal calculators, and electronics prohibited |
| Supplied materials | Scratch paper and pencil |
| Identification | Valid government photo ID required |
| Initial fee | $465 member / $590 non-member (non-member price includes one year of OPS membership; the $50 non-refundable application component is included, not extra) |
| Retest fee | $285 |
Two practical points follow from this table. First, 175 questions in 120 minutes leaves roughly 41 seconds per item, so you cannot afford to agonize. Second, because blank answers earn nothing and wrong answers cost nothing extra, you should answer every question, even if you have to eliminate one or two options and guess. The full pricing picture, including renewal, is in our CRA certification cost breakdown.
Where the Points Live: Weighting Strategy
The published weights sum to 100%, which makes triage straightforward. The table below lists all ten domains using the official names.
| Domain | Weight |
|---|---|
| Fluorescein Angiography with Fundus Camera or Scanning Laser Ophthalmoscope | 25% |
| Fundus Photography - Fundus Camera and Scanning Laser Ophthalmoscope | 23% |
| Applies the Principles of the Anatomy, Physiology, and Pathology of the Eye | 16% |
| General Photography | 10% |
| Patient Management and Patient/Operator Safety | 6% |
| Monochromatic Imaging and Fundus Autofluorescence | 5% |
| Pharmacology | 5% |
| Data and Image Management | 4% |
| Indocyanine Green (ICG) Angiography | 3% |
| Other Imaging Technology | 3% |
The top two domains account for 48% of the weights, and adding anatomy, physiology, and pathology brings the top three to 64%. A study plan that front-loads those three areas covers nearly two-thirds of the exam. That said, the bottom seven domains still make up over a third of your questions, and a candidate who ignores them can lose enough points to fall short. For a deeper walk through each area, see the complete guide to all 10 CRA content areas.
Mastering Fluorescein Angiography (25%)
This is the largest single domain and the heart of the credential. Expect questions that test whether you understand the physiology behind the images, not just the button sequence.
Fluorescein Angiography with Fundus Camera or Scanning Laser Ophthalmoscope
You must connect dye behavior, optics, and clinical findings, on both fundus camera and SLO platforms.
- Phase recognition: know the sequence of the angiographic phases and what a normal timing pattern looks like, so you can spot delayed or abnormal filling.
- Filters and spectral behavior: understand why exciter and barrier filters are paired and what happens when they are mismatched or degraded.
- Hyperfluorescence and hypofluorescence: be able to reason from a described image pattern to its likely cause, such as leakage, staining, pooling, window defects, or blocked fluorescence.
- Technique and timing: injection timing, image capture strategy, and what to do when a patient's circulation or cooperation changes the plan.
- Troubleshooting: poor contrast, media opacities, incorrect focus, and artifacts that mimic pathology.
A good drill is to take any angiogram you have captured and write out, in plain sentences, what each phase should show and what the abnormal version would look like. If you can explain it without notes, you are ready for the scenario questions.
Fundus Photography Fundamentals (23%)
The second-largest domain covers the bread-and-butter work of an ophthalmic photographer, on both fundus cameras and scanning laser ophthalmoscopes.
Fundus Photography - Fundus Camera and Scanning Laser Ophthalmoscope
Image quality, alignment, and standardized capture drive most questions here.
- Optical principles: illumination and observation paths, field of view, magnification, and how pupil size and media clarity limit image quality.
- Camera operation: focus, alignment, working distance, and exposure and flash settings.
- Standard views and montages: how fields are positioned and how overlapping images are planned for a complete composite.
- Stereo and special techniques: when and how to capture stereo pairs and what makes them diagnostically useful.
- Artifact identification: reflections, dust spots, uneven illumination, and how to correct each at the camera.
Because this domain is close to daily practice for working photographers, it is often where candidates feel most confident. Do not let that become overconfidence: the exam asks for the textbook reasoning behind what you do automatically. Write out the "why" for each standard step.
Anatomy, Physiology, and Pathology (16%)
This domain, formally titled "Applies the Principles of the Anatomy, Physiology, and Pathology of the Eye," is where imaging skill meets clinical knowledge. It is the third-largest area and the one that most often surprises technically strong photographers.
- Retinal layers and vasculature: know the dual blood supply concept and why different structures appear when they do in an angiogram.
- Common conditions: be able to match a described disease process to the imaging features you would expect, including diabetic retinopathy, age-related macular degeneration, vascular occlusions, and macular conditions.
- Barriers: understand the blood-retinal barrier and why its breakdown produces leakage.
- Terminology: exam questions use precise clinical vocabulary, so build a glossary and test yourself on it.
Key Takeaway
Do not study pathology as a list of diseases. Study each condition as an imaging pattern: what the fundus photo shows, what the angiogram shows, and why. That is how the exam asks about it.
The Smaller Domains Worth Real Time
The remaining seven domains total 36% of the weights. Individually small, collectively decisive.
General Photography (10%)
This tests photographic fundamentals such as exposure, lighting, depth of field, and composition, plus external and anterior-segment photography concepts. Strong ophthalmic photographers sometimes underestimate it because the vocabulary of general photography differs from daily clinical shorthand.
Patient Management and Patient/Operator Safety (6%)
Expect questions on patient communication, positioning, infection control, and responding to adverse reactions during dye injection. Know the difference between mild and serious reactions and the appropriate escalation for each, according to your facility's protocols.
Monochromatic Imaging and Fundus Autofluorescence (5%) and Pharmacology (5%)
Autofluorescence questions center on what structures and pigments produce signal and how to interpret reduced or increased signal. Pharmacology covers the agents involved in imaging, including mydriatics and the angiographic dyes, along with their uses, contraindications, and side effects.
Data and Image Management (4%), ICG Angiography (3%), and Other Imaging Technology (3%)
These are the lowest-weighted areas, but they are not throwaways. Know image storage, labeling, and privacy fundamentals; the characteristics of indocyanine green and how its infrared behavior differs from fluorescein; and the basics of other imaging modalities you may encounter in a retina practice. A short, focused review of each pays off because the questions tend to be direct.
Eligibility, Portfolio, and Application Timing
Before you can sit for the written exam, you have to clear the eligibility steps. The full breakdown is in our CRA requirements guide, but the essentials are:
- An accepted applicant-produced imaging portfolio.
- Verification from your employing physician or institution of two years of retinal-angiography experience.
- Current CPR, including a current in-person skills assessment.
- Specified education or professional credentials may substitute for up to one year of experience.
- Provisional CRA is a distinct status for candidates who are still completing the work-experience requirement.
OPS does not mandate a particular preparation course or a universal number of training hours. Submit your application and portfolio at least eight weeks before your desired examination date, because the portfolio must be reviewed and accepted before testing. If you are building your skills through formal instruction, see our overview of CRA training pathways.
An Eight-Week Domain-Driven Schedule
Rather than a generic template, this schedule sequences study by weight and dependency. Anatomy and physiology come first because they make the angiography material make sense. Adjust the pacing to your experience; a working angiographer may compress the early weeks, while a newer photographer may stretch them.
Foundations: Anatomy, Physiology, Pathology
- Build your terminology glossary and retinal anatomy sketches.
- Link each major condition to its expected imaging pattern.
- Take a short diagnostic quiz to expose gaps.
Fluorescein Angiography
- Review phases, filters, and abnormal fluorescence patterns.
- Practice reading angiograms and writing out interpretations.
- Cover technique, timing, and troubleshooting scenarios.
Fundus Photography and General Photography
- Review optics, alignment, montage planning, and stereo technique.
- Refresh exposure, lighting, and external photography concepts.
The Smaller Domains
- Patient safety and adverse reactions, pharmacology, autofluorescence, ICG, data management, and other imaging technology.
Timed Practice and Weak-Spot Repair
- Run full-length practice sets against the two-hour clock.
- Review every miss by domain and revisit the weakest areas.
For timed practice that mirrors the real format, use the question sets on the CRA practice test site. Pair that with the quick-reference facts in our CRA cheat sheet during the final week. Since 175 questions in two hours leaves little room to dawdle, practicing at pace matters as much as knowing the content.
Test-Day Mechanics
On exam day, bring a valid government photo ID. The exam is closed book, and outside references, personal calculators, and electronics are prohibited; the test center supplies scratch paper and a pencil. Use that scratch paper to jot down any mnemonics or timing sequences the moment the exam begins, then move on.
Pace yourself at roughly 40 seconds per question for a first pass. Answer what you know, make an educated pick on the rest, and flag anything you want to revisit if time allows. Since there is no extra penalty beyond earning no credit, never leave an item blank.
Scoring and What to Expect Afterward
Passing is determined by a criterion-referenced Modified Angoff V competency standard with scaled reporting. That means you are measured against a competency standard rather than ranked against other candidates. No current numeric cut score is publicly verified, so be wary of any source claiming a specific percentage you must hit; our CRA passing score guide explains what is and is not known. Passing candidates receive a pass notice without a numeric score. Candidates who do not pass receive a scaled score and a diagnostic content-area report, which is a genuinely useful roadmap for a retest. Initial score reports are provisional pending a 72-hour statistical verification, and the Program Guide allows for reporting delays during exam-development cycles.
After You Pass: Recertification
Certification is not permanent. Recertification runs on three-year cycles beginning January 1 of the year after you earn the credential. To renew, you need 15 continuing education credits (CECs) earned during the cycle, including at least five from attending official OPS or OPS BOC pre-approved courses or workshops. Teaching, eligible non-OPS-approved attendance, and publication categories are each capped at ten credits, and eligible non-OPS attendance earns 0.5 CEC per hour. The alternative is retaking the examination by the end of year three.
Renewal costs $100 for members and $225 for non-members. If you renew by retesting, you pay the examination fee without an additional recertification fee. OPS's live renewal pages reference current CPR and accept specified American Heart Association or American Red Cross online refresher testing, while the June 2026 guide's renewal checklist omits CPR; confirm the current requirement with OPS when your cycle comes up.
If you are weighing whether the investment pays off, our analyses of whether CRA certification is worth it, CRA earnings, and CRA jobs will help you make that decision with eyes open.
Frequently Asked Questions
The written exam has 175 multiple-choice questions, each with four choices and one correct or best answer, and a two-hour time limit. OPS does not separately disclose how many items are scored versus unscored.
Fluorescein Angiography (25%) and Fundus Photography (23%) together account for 48% of the published weights, and Anatomy, Physiology, and Pathology adds another 16%. Prioritize those three, but do not neglect the smaller domains, which collectively make up over a third of the exam.
No current numeric cut score is publicly verified. OPS uses a criterion-referenced Modified Angoff V competency standard with scaled reporting. Aim for solid mastery of every domain rather than a specific percentage.
The initial fee is $465 for OPS members and $590 for non-members, with the non-member price including one year of OPS membership. A retest costs $285. The $50 non-refundable application component is already included in these figures.
Submit your application and imaging portfolio at least eight weeks before your desired exam date. The portfolio must be accepted before you can test, so starting it early prevents delays.
Success on the CRA exam comes from matching your effort to the published weights, grounding your knowledge in real imaging scenarios, and practicing at the pace the two-hour clock demands. When you are ready to test your readiness, head to the CRA practice test and start working through timed questions by domain.
