Fundus Camera vs OCT: What Should an Optometry Clinic Buy First?

fundus camera

For many clinic owners, the first major imaging purchase comes down to a fundus camera or an OCT machine. Both support retinal assessment, baseline records and clearer referrals, yet they answer different clinical questions.

A fundus camera records a colour image of the retinal surface. OCT records cross-sectional data from retinal and optic nerve structures. One gives broad visual documentation; the other gives depth, layer analysis and repeatable measurements.

The right first purchase depends on your patient mix, clinical scope, staff capability, room layout, referral pathway and capital plan. This guide compares fundus camera vs OCT options through a practical clinic lens.

Key Highlights

  • Choose a fundus camera first when routine retinal screening, colour documentation and fast image sharing are central to the clinic.
  • Choose an OCT machine first when glaucoma assessment, macular disease review or co-management forms a large part of weekly work.
  • Fundus photography and OCT are complementary. Neither device should be treated as a complete eye examination on its own.
  • Measure value through scan demand, staff time, repeat imaging, referral quality, service support and downtime.
  • Clinics with strong demand across screening and structural assessment may gain more from a combined or staged setup.

What Each Device Solves Clinically

fundus camera captures a two-dimensional image of the retina, optic disc, macula and visible retinal vessels. Field of view varies by model, from posterior-pole imaging to widefield capture.

Colour photography creates a baseline for diabetic retinopathy screening, optic disc and macular records, visible lesion documentation, referral attachments and mobile workflows.

Digital retinal imaging can support diabetic retinopathy detection, yet it does not replace a complete dilated examination when clinical findings or image quality call for one. The American Academy of Ophthalmology states that validated digital imaging can be an effective detection method, with dilated fundus examination remaining the reference standard in its diabetic retinopathy guidance.

BOC Instruments supplies fixed, automated and portable Fundus Cameras for different clinical settings. Available configurations can support room-based screening, delegated capture, outreach work and mobile imaging.

When comparing models, review:

  • Field of view
  • Minimum pupil size
  • Mydriatic and non-mydriatic capability
  • Autofocus and auto-capture functions
  • Image resolution
  • DICOM or practice software compatibility
  • Portability and room requirements
  • Training and servicing arrangements

What an OCT machine records

Optical coherence tomography creates cross-sectional images from reflected light. It can show retinal layers, retinal nerve fibre layer thickness, ganglion cell analysis, macular fluid, pigment epithelial change and vitreomacular interface findings.

An OCT machine can support:

  • Macular fluid assessment
  • Drusen and retinal pigment epithelium review
  • Vitreomacular disorder assessment
  • Retinal nerve fibre layer analysis
  • Glaucoma progression review
  • Corneal or anterior segment protocols on compatible systems
  • OCT angiography on selected models


Evidence for glaucoma assessment is substantial. A meta-analysis covering 150 studies, 16,104 glaucomatous eyes and 11,543 normal eyes reported an area under the receiver operating curve of 0.897 for average retinal nerve fibre layer measures and 0.885 for macular ganglion cell complex measures. The researchers described OCT as an adjunct to diagnosis rather than a stand-alone test.

BOC’s range of Optical Coherence Tomographs includes systems suited to general optometry, glaucoma assessment, macular imaging and advanced multimodal workflows.

Selection should rest on scan protocols, reports, software, operator steps and service access rather than one technical specification.

A 2024 posterior-pole screening study found gradable images in 97.5% of OCT examinations and 73.5% of fundus photographs. OCT produced stronger agreement between optometrist and ophthalmologist assessments, with a kappa value of 0.50 compared with 0.39 for photography.

Sensitivity was similar, and photography had slightly higher specificity. The findings support complementary use rather than proving one modality is best for every clinic.

Diagnostic Use Cases by Practice Type

General optometry and screening-led practices

A general practice may use a fundus camera across a larger share of routine examinations. It often suits clinics with high patient volume, a strong diabetes screening service, several trained operators or a staged capital plan.

Colour images can support:

  • Baseline retinal documentation
  • Diabetic retinopathy screening
  • Optic disc comparison
  • Macular records
  • Patient file documentation
  • Referral communication
  • Review of visible retinal changes over time


For diabetes services, non-mydriatic photography has a defined role in Australia. Current Medicare Benefits Schedule guidance covers bilateral retinal photography for eligible diabetes assessments and directs referral when retinopathy is detected or images are inadequate.

Eligibility differs by provider type and patient criteria. Clinics should check current MBS requirements before preparing a revenue forecast.

Glaucoma-focused practices

Clinics with a high glaucoma-suspect load may place OCT first. Structural analysis can add retinal nerve fibre layer and ganglion cell data to disc assessment, tonometry, gonioscopy, pachymetry and visual fields.

NICE glaucoma guidance recommends several tests before referral, including visual fields, stereoscopic optic nerve assessment, intraocular pressure measurement and angle assessment. OCT or an optic nerve head image may contribute where available.

This supports a multi-test model rather than an OCT-only diagnosis.

An Australian study reviewed 994,461 patients across 331 optometry practices. Practices using routine OCT had 1.39 times the adjusted odds of glaucoma referral compared with practices without routine OCT. In a subset with ophthalmologist feedback, 21% of referrals were judged not to have glaucoma.

The findings point to stronger case-finding and a continued need for careful interpretation.

Macular disease and ageing patient groups

OCT is commonly the stronger first investment for clinics managing many patients with:

  • Age-related macular degeneration
  • Diabetic macular oedema
  • Retinal vein occlusion
  • Epiretinal membrane
  • Vitreomacular traction
  • Central serous chorioretinopathy
  • Unexplained visual change


OCT can show fluid and layer changes that may not be clear on a colour photograph.

Optometry Australia’s 2024 AMD Clinical Practice Guide recommends colour fundus photography and OCT for AMD imaging. It reports that reticular pseudodrusen may be missed in about half to three-quarters of eyes on colour photographs and can be distinguished on OCT.

Colour imaging remains useful for recording haemorrhage, pigmentation, visible drusen and lesion distribution.

Regional and mobile clinics

Portable retinal photography can suit outreach work where transport, room footprint and quick image transfer matter. OCT may still be the right first device for a regional clinic with a strong glaucoma or macular caseload.

The decision needs a service plan covering:

  • Installation
  • Remote technical support
  • Staff training
  • Parts availability
  • Loan equipment
  • Repair turnaround
  • Software support
  • Data backup


BOC’s customer profile identifies downtime and limited on-site support as major concerns for regional clinics. The brand’s service model focuses on continuity across the equipment lifecycle.

Ask BOC to review your patient mix, room plan and referral pathway before a quotation is finalised. A fit-out consultation can narrow the shortlist to systems that match daily clinical use.

Budget, Throughput and Referral Impact

Compare lifecycle cost, not the quote alone

The purchase price is one part of the investment. Clinics should review the total installed and supported cost across the expected equipment lifecycle.

Include:

  • Hardware
  • Software licences
  • Delivery
  • Installation
  • Staff training
  • Warranty terms
  • Preventive servicing
  • Repair response
  • Loan-unit access
  • Networking
  • Room modifications
  • Future upgrades


Clinics comparing OCT configurations can use BOC’s OCT machine guide to assess clinical requirements, scan features, workflow needs and long-term ownership factors.

A lower initial quote may offer less value when software support, training, parts or local servicing are limited. Equipment downtime can affect bookings, referral timelines and patient flow.

Test the real weekly workflow

A fast scan speed does not always produce a fast appointment. Patient positioning, repeat scans, data entry and report review all affect throughput.

During a demonstration, record:

  • Average capture time
  • Number of repeat attempts
  • Ease of patient positioning
  • Report access
  • Progression comparison tools
  • Referral export quality
  • Staff confidence
  • Performance with small pupils
  • Performance with media opacity
  • Performance with poor fixation


Consistent capture may matter more than headline scan speed. Ask several team members to operate the device during the trial rather than relying on a supplier-led demonstration alone.

Measure referral quality

A new imaging device may increase the number of findings. Clinics still need internal rules for artefacts, incidental findings, urgency grading and clinical correlation.

The HERMES trial studied a teleophthalmology pathway for community optometry retinal referrals using OCT data and specialist review. It reported a 59% reduction in false-positive urgent referrals among referred participants compared with standard care.

The result reflects the full clinical pathway rather than the device in isolation. It shows the value of structured image transfer, clear review criteria and specialist input.

Ask regular referrers what information helps them triage or accept a case. The answer may favour colour images, OCT reports or both.

Build a simple return model

Use actual clinic data rather than supplier assumptions.

Estimated monthly imaging contribution

“Completed scans per month × average contribution per scan”

Subtract:

  • Finance or depreciation
  • Service costs
  • Staff time
  • Software fees
  • Consumables
  • Expected downtime
  • Training time

Track operational gains that may not appear as direct imaging revenue:

  • Better baseline records
  • Faster referrals
  • Fewer repeat visits
  • Less external imaging
  • More consistent co-management reports
  • Improved clinical documentation
  • Reduced administrative handling


A clinic purchasing high-value retinal imaging equipment should model conservative, expected and high-demand scenarios before committing capital.

When Clinics Need Both

The modalities answer different questions

Fundus photography shows visible retinal appearance. OCT shows structural depth.

A suspicious macular change may need a colour record and a B-scan. A glaucoma assessment may need disc photography, OCT, visual fields, pressure data and examination findings.

The case for both becomes stronger when:

  • The clinic manages routine screening and disease co-management
  • Referrers request both image types
  • External imaging creates delays
  • Patients often need repeat appointments for separate imaging
  • The clinic manages a high number of glaucoma and macular cases
  • Clinical records need both surface appearance and structural measurements

A staged purchase may suit cash flow

A clinic can begin with the device that serves the larger share of current patients, then add the second modality after demand is measured.

A general clinic may start with a fundus camera for routine retinal records. A co-management-heavy clinic may begin with an OCT machine. The second device can be introduced when scan volume, referrals and staff capability support the investment.

A staged plan gives the clinic time to assess:

  • Actual imaging demand
  • Staff training needs
  • Patient flow
  • Referral patterns
  • Room capacity
  • Revenue contribution
  • Service experience

Combined systems can suit limited space

Combined systems can be practical where floor space, operator movement or patient transfer creates workflow pressure.

BOC lists dual-modality systems that combine OCT and non-mydriatic fundus imaging in one automated unit. A combined platform may reduce equipment footprint and limit the need to reposition patients between separate devices.

Clinics should still assess:

  • Image quality for each modality
  • Available scan protocols
  • Fundus field of view
  • Report format
  • Progression tools
  • Capture speed
  • Service access
  • Software support
  • Staff usability


A combined unit should be judged on both functions. Strong performance in one modality does not confirm that the second function meets the clinic’s needs.

Frequently Asked Questions

No. OCT gives cross-sectional structural detail. A fundus camera gives a colour record of the retinal surface. The stronger choice depends on the clinical task and patient mix.

No. Photography cannot show retinal layers, fluid pockets or quantitative thickness data in the same way as OCT.

Not in every clinic. Many OCT systems have limited peripheral coverage and do not produce a true colour retinal image. Photography may give clearer records of haemorrhage, pigmentation, vessels and lesion location.

Automated fundus photography is often straightforward for trained staff. Automated OCT capture can be delegated, but quality checks and interpretation require deeper OCT knowledge.

A fundus camera may reach more routine patients in a general clinic. OCT may create greater clinical value in a practice with strong glaucoma, AMD or macular demand.

The clinic should assess:

  • Completed scan volume
  • Net contribution
  • Staff time
  • Service costs
  • Referral demand
  • Repeat imaging rates
  • Clinical record value

Ask to see:

  • A complete patient capture
  • Common difficult cases
  • Repeatability tools
  • Progression reports
  • Referral exports
  • Backup processes
  • Training requirements
  • Service response arrangements
  • Loan-unit terms
  • Software support periods

A combined system may suit clinics with limited room space or frequent demand for both modalities. Separate devices may offer more choice in field of view, scan protocols and future replacement planning.

The fundus camera vs OCT decision is less about selecting the more advanced device and more about matching imaging capability to the work your clinic performs each week. Start with clinical demand, test the workflow, review ownership costs and plan service continuity from day one.
