When Should an Optometrist Refer? The Grey Areas Between Optometry and Ophthalmology

Referral is one of the most important clinical decisions an optometrist makes, but it is rarely as straightforward as recognising a textbook condition and sending the patient to an ophthalmologist. In primary eye care, many patients present with findings that sit somewhere between routine optometric management and specialist investigation. The challenge is deciding not only whether to refer, but who to refer to, how urgently, and what clinical information the receiving practitioner needs.

For an optometrist, this is where clinical judgement matters most. A referral should be based on the patient's symptoms, clinical findings, risk factors and the limits of what can appropriately be managed within the practice. It should also be clear enough that the receiving practitioner can understand why the patient has been referred and what has already been investigated.

Referral is about more than recognising pathology

Some referral decisions are obvious. A patient with a potentially sight-threatening condition, significant acute symptoms or findings requiring specialist intervention should be referred promptly. Other cases are much less clear. An unusual finding may warrant further investigation but not necessarily an emergency referral. A patient may require ophthalmology, but another may be better directed towards a different specialist or healthcare professional.

This distinction matters because inappropriate referrals can create unnecessary pressure on specialist services, while delayed or missed referrals can have much more serious consequences for the patient. Research into optometric referral pathways has found that referral filtering, guidelines and teleophthalmology can reduce unnecessary referrals, while also highlighting the importance of maintaining clinical safety and avoiding false negatives.

The answer, therefore, is not to refer everyone who presents with an unusual finding. Nor is it to try to manage everything within primary eye care. The goal is to make a clinically appropriate decision based on the information available.

The importance of a good referral

Once the decision to refer has been made, the quality of the referral becomes just as important as the decision itself.

A referral should give the receiving practitioner enough information to understand the clinical concern without having to reconstruct the entire consultation. This may include relevant symptoms, visual acuity, examination findings, imaging, intraocular pressure, anterior and posterior segment findings, previous history and any other investigations that influenced the decision to refer.

This is particularly important when a patient is being referred for a specific clinical concern rather than simply for a second opinion. A clear referral communicates the optometrist's clinical reasoning and gives the receiving practitioner a useful starting point for further assessment.

Making referrals part of the clinical workflow

This is an area where digital clinical records can make a meaningful difference. Referral documentation should not require the optometrist to start writing a separate letter from scratch every time a referral is necessary. The information relevant to the referral already exists within the patient's clinical record.

In ASIRA, the discharge summary can be used to create a structured referral from the patient's existing clinical information. The optometrist can select the evaluations that are relevant to the referral rather than sending an unnecessarily large amount of information. This allows the referral to be focused on the clinical question that needs to be addressed while still providing the receiving practitioner with the supporting findings.

The optometrist can also specify the type of practitioner to whom the patient is being referred. This helps distinguish between different referral pathways rather than treating every referral as an ophthalmology referral. The urgency of the referral can also be selected, allowing the optometrist to clearly communicate whether the patient requires routine follow-up, a more timely assessment or urgent attention.

This may sound like a small change to the workflow, but it addresses an important problem in clinical practice: the gap between making a referral decision and communicating that decision effectively.

Referral urgency deserves particular attention

The urgency attached to a referral is not simply an administrative field. It communicates clinical priority.

A referral that does not clearly indicate urgency can leave the receiving practitioner or service to interpret the priority themselves. Conversely, over-classifying referrals as urgent can contribute to unnecessary pressure on specialist services. Recent research into optometry referral pathways has specifically identified incorrect referral urgency as an issue, demonstrating why triage and referral prioritisation need to be considered alongside the referral decision itself.

Having urgency built directly into the referral workflow encourages the optometrist to make that decision deliberately. It also creates a clearer communication pathway between primary eye care and the practitioner receiving the referral.

Where AI can support clinical judgement

The grey areas of referral are also where clinical decision support can potentially be useful. Artificial intelligence should not replace the optometrist's clinical judgement, but it can provide another layer of support when the findings do not lead to an obvious decision.

ASIRA AI can help guide the optometrist when considering whether a referral may be appropriate by assessing the clinical information entered into the patient's record and providing decision support around the referral. The purpose is not to tell the optometrist what to do, but to prompt consideration of whether the findings and clinical context support referral and whether further assessment may be appropriate.

This distinction is important. The responsibility for the clinical decision remains with the optometrist. AI can act as a second set of eyes, helping clinicians consider information that may otherwise be overlooked, particularly in cases where the presentation is less straightforward.

There is growing interest in exactly this role for AI and clinical decision-support systems in eye care. Research has identified potential applications for AI in referral and triage pathways, while also emphasising that these systems require appropriate clinical oversight and validation.

Better referrals mean better continuity of care

The referral is not the end of the optometrist's involvement in the patient's care. It is a handover from one part of the healthcare system to another.

A good referral tells the next practitioner what the optometrist found, what prompted concern, what has already been assessed and how urgently the patient needs to be seen. When this information is structured and communicated clearly, the receiving practitioner can make better use of their consultation time and the patient is less likely to have to repeat their entire story.

For optometrists, the ability to create a referral directly from the clinical record also means that referral becomes part of the normal examination workflow rather than a separate administrative task.

Knowing when to refer is part of being a good optometrist

Good optometry is not about diagnosing and managing everything independently. It is about recognising the limits of primary eye care, identifying when additional expertise is required and making sure the patient reaches the right practitioner at the right time.

The grey areas will always exist. Clinical findings do not always fit neatly into categories, and referral decisions will continue to require professional judgement. What can change is how well that judgement is supported and communicated.

With structured clinical documentation, clear referral pathways and appropriate decision-support tools, optometrists can make referrals more deliberately, communicate their concerns more effectively and maintain better continuity of care.

Ultimately, a good referral is not simply a letter that says, "Please see this patient." It is a clinical handover that explains why the patient needs to be seen, what has been found, who needs to see them, and how urgently they need to be assessed.
