If you are preparing for the Certified Retinal Angiographer credential, the single most useful document is the blueprint that tells you what the exam actually measures. The Ophthalmic Photographers' Society (OPS) Board of Certification publishes ten weighted examination content areas in its CRA Program Guide (version 15.1, effective June 2026). These areas are official exam objectives drawn from the 2017 job analysis, which means they reflect what working retinal angiographers actually do rather than what a training course happens to cover.
This guide walks through every domain by name, explains what each one is likely to ask of you, and shows how to turn the published weights into a sensible study order. If you are still deciding whether to pursue the credential, start with What Is CRA Certification? and CRA Requirements 2026: Eligibility, Prerequisites & How to Qualify, then come back here to plan your preparation.
The Ten Domains and Their Weights at a Glance
The table below lists each domain exactly as the blueprint names it, along with its published weight. Because the weights sum to 100%, they are the clearest available signal of how your study hours should be distributed.
| 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% |
The Two Heavy Domains: Fluorescein Angiography and Fundus Photography
Domain 7: Fluorescein Angiography (25%)
This is the largest domain and the heart of the credential. The title specifies fluorescein angiography performed with either a fundus camera or a scanning laser ophthalmoscope (SLO), so expect questions that treat both platforms rather than assuming one device.
Fluorescein Angiography with Fundus Camera or Scanning Laser Ophthalmoscope
Candidates must understand the complete procedure from patient preparation to image interpretation.
- The phases of the angiogram and the timing relationships between them
- Filter selection and how excitation and barrier filters work together
- Injection technique, dye delivery, and what to do when timing goes wrong
- Recognizing common patterns such as hyperfluorescence and hypofluorescence, and what each can indicate
- Troubleshooting poor-quality images: exposure, focus, media opacity, and patient cooperation
- Differences in image acquisition and appearance between fundus camera and SLO systems
Because this domain also overlaps with safety and pharmacology, questions about adverse reactions to the dye can appear in several guises. Treat it as the anchor of your preparation and revisit it repeatedly, not once.
Domain 5: Fundus Photography (23%)
Fundus photography is nearly as heavy as angiography, and it is where many candidates underinvest because the work feels routine. The blueprint covers both the fundus camera and the scanning laser ophthalmoscope, so the domain tests whether you can produce consistent, diagnostic-quality color and filtered images on either platform.
Fundus Photography - Fundus Camera and Scanning Laser Ophthalmoscope
Expect questions on image quality, field coverage, and technique rather than purely theoretical optics.
- Standard fields and montage construction for documenting the posterior pole and periphery
- Stereo photography technique and why it matters for depth assessment
- Alignment, working distance, focus, and flash or illumination adjustments
- Common artifacts, their causes, and how to correct them at the camera
- Handling small pupils, media opacities, and difficult fixation
Together these two domains reward hands-on familiarity. If your daily work leans heavily toward one platform, deliberately study the other, since the exam does not assume your clinic's equipment matches the blueprint.
Foundation Domains: Anatomy, Safety, Photography, and Data
Domain 1: Anatomy, Physiology, and Pathology of the Eye (16%)
At 16%, this is the third-largest domain and the one that gives meaning to everything else. You cannot interpret an angiogram without knowing what the retinal and choroidal circulations look like normally and how disease disrupts them. The domain title explicitly includes pathology, so questions go beyond naming structures to recognizing how disease presents in images.
- Layers of the retina and the separate vascular supplies of the retina and choroid
- The blood-retinal barriers and why their breakdown produces leakage
- Common posterior-segment conditions you will photograph, including diabetic retinopathy, age-related macular degeneration, retinal vascular occlusions, and macular edema
- How pathology alters the expected appearance on fundus images and angiograms
Domain 3: General Photography (10%)
General Photography is the principles layer beneath all of your imaging: light, optics, exposure, and image formation. It supports Domains 5 and 7, so a weak grasp here quietly costs you points elsewhere. Expect questions on resolution, depth of field, filters, color, and the relationship between exposure variables, applied to ophthalmic contexts.
Domain 2: Patient Management and Patient/Operator Safety (6%)
This domain is small but practical. It covers communicating with patients, obtaining cooperation, positioning, infection control, and recognizing and responding to emergencies. Because retinal angiography involves intravenous dye and the possibility of a reaction, knowing the correct response sequence is the kind of question that rewards clear, procedural memory. For background on the certification's practical prerequisites, including current CPR, see CRA Requirements 2026.
Domain 4: Data and Image Management (4%)
The smallest of the foundation domains addresses how images are named, stored, retrieved, and protected. Think file organization, patient identification accuracy, image quality control, archiving, and privacy considerations. It is a modest slice of the exam, but the questions tend to be straightforward and reward careful reading more than deep study.
Specialty Imaging: Autofluorescence, ICG, Pharmacology, and Other Technology
Domain 6: Monochromatic Imaging and Fundus Autofluorescence (5%)
This domain covers red-free and other monochromatic imaging, along with fundus autofluorescence (FAF). Know what each technique is designed to highlight, why a filtered or monochromatic image reveals features that color photography can mask, and how autofluorescence reflects the metabolic state of the retinal pigment epithelium. Candidates often find this domain easier once Domains 5 and 7 are solid, since it builds on the same optical foundations.
Domain 8: Indocyanine Green (ICG) Angiography (3%)
ICG angiography images the choroidal circulation using a near-infrared dye. Although it carries only 3% of the weight, it is conceptually distinct from fluorescein, so it is worth understanding what ICG shows that fluorescein does not and why. Focus on the contrast between the two dyes: wavelengths, the structures each best visualizes, and the clinical situations where ICG is chosen.
Domain 9: Pharmacology (5%)
Pharmacology links directly to safe angiography. Expect questions on dilating agents, the dyes used in angiography, contraindications, possible adverse reactions, and emergency medications. Treat it as a companion to Domain 2 and Domain 7, since a dye-reaction question can blend all three.
Domain 10: Other Imaging Technology (3%)
The final domain is a catch-all for imaging modalities beyond the core photographic and angiographic techniques. At 3%, you need working familiarity rather than mastery: understand what each additional modality captures, how it complements angiography, and the general principles behind it.
A Quick Way to Classify the Small Domains
Group the four smallest content areas by their relationship to the big ones.
- Study with Domain 7: ICG Angiography (8) and Pharmacology (9)
- Study with Domain 5: Monochromatic Imaging and Autofluorescence (6)
- Study on its own, briefly: Data and Image Management (4) and Other Imaging Technology (10)
Question Format and Exam Mechanics
The written exam consists of 175 multiple-choice questions. Each has four answer choices with one correct or best answer, and you have two hours. OPS does not separately disclose how many of those questions are scored versus unscored, so plan to treat every question as if it counts. There is no extra penalty for guessing beyond receiving no credit for an incorrect or blank answer, which makes answering every question the sensible default.
- Delivery: Prometric computer-based test-center delivery. No current remote or adaptive option is verified.
- Closed book: Outside references, personal calculators, and electronics are prohibited. Scratch paper and a pencil are supplied.
- Identification: A valid government photo ID is required.
- Scoring: The standard is criterion-referenced, set with a Modified Angoff V competency method and reported as a scaled score. No current numeric cut score is publicly verified, so be wary of any source claiming one. Our breakdown in CRA Passing Score 2026 explains what is and is not known.
- Results: Passing candidates receive a pass notice without a numeric score. Failing candidates receive a scaled score and a diagnostic content-area report. Initial score reports are provisional pending a 72-hour statistical verification.
Fees and Application Mechanics That Affect Your Timeline
The initial fee is $465 for OPS members and $590 for non-members, with an optional one-year OPS membership included in the non-member price. The $50 non-refundable application component is already included in those amounts, not added on top. A retest costs $285. For a full breakdown, see CRA Certification Cost 2026: Complete Pricing Breakdown.
Eligibility is not a simple sign-up. You need an accepted applicant-produced imaging portfolio, verification from an employing physician or institution of two years of retinal-angiography experience, and current CPR including a current in-person skills assessment. Specified education or professional credentials can substitute for up to one year of experience, and a Provisional CRA status exists for candidates still completing the work-experience requirement. The guide advises submitting your application and portfolio at least eight weeks before your desired exam date, so build that lead time into your plan. For scheduling, see CRA Exam Dates 2026.
Turning the Weights Into a Study Sequence
The blueprint suggests an obvious principle: study in proportion to weight, but sequence by dependency. Anatomy and pathology give meaning to the images, general photography supports the camera work, and the large imaging domains then draw on both. A sensible order front-loads the foundations, spends the most time on Domains 5 and 7, and saves the small specialty domains for later weeks when they can attach to material you already know.
Build the Foundation
- Domain 1: retinal layers, dual circulation, and the major pathologies
- Domain 3: optics, exposure, and filter principles that Domains 5 and 7 rely on
Fundus Photography Depth
- Domain 5: fields, stereo technique, artifacts, and platform differences
- Domain 6: monochromatic imaging and autofluorescence as an extension of the same skills
Fluorescein Angiography Mastery
- Domain 7: phases, filters, injection, patterns, and troubleshooting
- Domains 8 and 9: ICG and pharmacology, studied alongside fluorescein for contrast
Safety, Data, and Remaining Topics
- Domain 2: patient management and emergency response
- Domains 4 and 10: image management and other imaging technology
Integration and Practice
- Mixed timed sets of roughly 175 questions to rehearse the two-hour pace
- Targeted review of whichever domains your practice results show as weakest
This sequence assumes you already work in or near retinal imaging, since eligibility requires experience. If your hands-on exposure to one modality is thin, extend the relevant week. For a broader preparation framework, read the CRA Study Guide 2026: How to Pass on Your First Attempt, and for a sense of how demanding the material is, see How Hard Is the CRA Exam?. When you are ready to test yourself against realistic questions, try the CRA practice tests, which are organized to reflect these ten content areas.
Key Takeaway
Let the diagnostic report guide a retake. If you do not pass, the content-area report tells you which domains to rebuild. Because the same ten weights apply on every attempt, a retest ($285) is best spent on a targeted rebuild of your weakest weighted areas rather than a full restart.
