Barriers to Accessible Ophthalmic Imaging Device Uptake: An Exploratory Study Of Ophthalmology Care Provider Perspectives
Modern eye care relies heavily on imaging technologies such as optical coherence tomography (OCT), fundus cameras, and visual field analyzers to diagnose and monitor eye disease. However, many of these devices were designed for patients who can easily sit upright, position their head on a chinrest, and remain still during testing. This creates significant challenges for people who use wheelchairs, have limited mobility, dementia, intellectual disabilities, or other physical conditions that make standard imaging difficult. The researchers sought to understand why more accessible imaging devices—which include portable, handheld, or height-adjustable equipment—have not been widely adopted despite their potential to improve patient care. To answer this question, they surveyed ophthalmologists, optometrists, nurses, orthoptists, and other eye care professionals across Australia about the barriers they encounter in clinical practice.
The survey revealed that clinicians recognize accessibility as an important issue and generally believe that accessible imaging devices can produce reliable, high-quality images. However, several obstacles continue to limit their use. Cost emerged as the most commonly cited barrier, with many respondents reporting that specialized equipment is expensive and difficult to justify within existing budgets. Participants also reported limited awareness of the available technologies, insufficient training on how to use them effectively, and concerns that some devices remain difficult for patients with disabilities to operate. Imaging was reported to be particularly challenging for wheelchair users and patients with cognitive impairments, highlighting that accessibility is not only a matter of equipment design but also of workflow and staff preparation.
When asked how accessibility could be improved, clinicians emphasized the need for more flexible and user-friendly equipment. Suggestions included imaging systems with adjustable table heights, removable chinrests, wearable or handheld devices, wider bases to accommodate wheelchairs, and equipment capable of capturing multiple types of images without requiring repeated patient repositioning. Participants also recommended integrating software that combines data from different imaging devices into a single platform, making examinations more efficient. Beyond equipment design, respondents stressed that formal staff training, greater familiarity with accessible technologies, and demonstrations from device manufacturers could improve confidence and encourage wider adoption in everyday clinical practice.
The authors also argue that improving accessibility requires changes beyond the clinic itself. Financial incentives, government funding, and reimbursement policies could help practices invest in accessible equipment, while regulatory standards increasingly recognize accessibility as a component of high-quality healthcare. As populations age and more patients live with mobility limitations or chronic disabilities, ensuring that everyone can receive accurate ophthalmic imaging becomes a matter of health equity as well as clinical effectiveness. Better access to imaging could lead to earlier diagnosis of conditions such as glaucoma, diabetic retinopathy, and age-related macular degeneration, reducing the risk of preventable vision loss for underserved patient groups.
Overall, the study concludes that the technology needed to make ophthalmic imaging more inclusive already exists, but widespread adoption has been slowed by practical and systemic barriers rather than technical limitations. The authors acknowledge that their survey included a relatively small sample of Australian eye care providers, meaning additional research is needed to confirm these findings in other healthcare systems. Even so, the message is clear: improving accessibility will require collaboration among device manufacturers, clinicians, healthcare organizations, and policymakers. By investing in better-designed equipment, staff education, and supportive funding, the eye care community can make diagnostic imaging more equitable and ensure that patients with disabilities receive the same standard of care as everyone else.
