A thorough clinical history is the foundation of effective diagnosis and management in ophthalmology. In patients presenting with visual complaints, it can distinguish between urgent and non-urgent conditions and guide appropriate management.
However, for many trainees, this process can feel unfamiliar due to limited exposure during training. Thus, this article outlines a practical, step-by-step approach to taking an effective ophthalmology history.
Patient's Ophthalmology History
Presenting Complaint
Key points to clarify patient concerns include:
Nature of the problem (blurred vision, eye pain, redness, diplopia, flashes, floaters, or vision loss)
Laterality (one eye or both)
Onset (sudden or gradual)
Duration (hours, days, months, or years)
Progression (stable, improving, or worsening)
The consultation should begin by inviting the patient to describe their primary concern. Following this, the clinician should clarify key features of the presenting complaint, including laterality, onset, duration, pattern, and progression.
Understanding whether symptoms developed suddenly or gradually, and whether they are stable or worsening, is particularly important in identifying potentially sight-threatening conditions.
A simple framework such as the mnemonic SIGHT can help ensure that these core elements are consistently addressed. Mnemonic SIGHT is:
- Symptom type (nature: blur, pain, diplopia, flashes, floaters)
- Involved eye (laterality)
- Gradual or sudden (onset)
- How long (duration)
- Trend (progression)
History of Presenting Complaint
After presenting the complaint, the ophthalmology history should be explored in more detail:
Visual symptoms
Pain and discomfort
Redness and discharge
Neurological or vascular symptoms
Visual symptoms should always be characterised further by asking about changes in both distance and near vision, as well as whether visual loss is central or peripheral, transient or persistent.
In addition, it is important to enquire about other important sight-related symptoms that the patient may be experiencing. Such as blurred vision, ocular pain, whether it is exacerbated by movement, headaches, photophobia, redness, diplopia, flashes, floaters, visual loss, or discharge.
This is important as associated symptoms can help differentiate between pathologies. For example, the presence of headache or photophobia may suggest inflammatory or neurological causes. Conversely, the presence of redness and discharge may indicate irritation or an infectious cause.
Furthermore, neurological and vascular features should not be overlooked. It is important to exclude symptoms like diplopia, ptosis, or visual field defects, as these may indicate cranial nerve involvement or intracranial pathology. When assessing a patient presenting with transient visual loss, it is vital to exclude a transient ischaemic attack as a possible cause.
Past Ocular History
Ask about any previous eye-related conditions or treatments:
Previous eye diseases or surgeries
Trauma or infections
Glasses or contact lenses
Episodes of similar symptoms
A focused past ocular history is useful in providing clinical context and may make certain diagnoses more or less likely. Establishing whether similar symptoms have occurred in the past can differentiate between recurrent and new pathology. Previous eye conditions, surgeries, ocular trauma, or infections can also guide differential diagnosis.
It is essential to always enquire about a patient’s use of corrective lenses such as glasses or contact lenses. Myopia and hypermetropia can act as risk factors. Whilst myopia may predispose to retinal detachment and open-angle glaucoma, hypermetropia is a major risk factor for acute angle-closure glaucoma.
In addition, contact lens use is a significant risk factor for corneal abrasions and eye infections.
Medical History
Systemic diseases often have ophthalmic manifestations:
Diabetes mellitus
Hypertension
Autoimmune or inflammatory diseases
Thyroid disorders
Neurological conditions
Infectious diseases
History of stroke or cardiovascular disease
Particularly in cases of visual disturbance, it is important to enquire about previous cardiovascular disease or stroke, which may point towards a vascular cause.
A detailed medication history is also essential. In addition to documenting regular medications and ocular treatments, clinicians should specifically ask about steroid use, which can predispose to glaucoma and cataracts. Some other potentially ocular toxic medications include isotretinoin, which can cause severe dry eyes, and hydroxychloroquine, which can cause retinal toxicity.
It is also important to enquire about ocular treatment such as eye drops, and if this is prescribed, whether they are compliant with it. In conditions such as open-angle glaucoma, poor compliance with latanoprost eye drops may lead to progressively worsening visual impairment.
Medication History
Document all medications, including:
Current systemic medications
Eye drops or ocular treatments
Steroid use
Isotretinoin or hydroxychloroquine
History of drug allergies
Medication history is essential, as many drugs can cause side effects in the eyes.
Family History
Family history can provide insight into familial eye diseases. Enquiring about family history of conditions such as glaucoma, retinal dystrophies, age-related macular degeneration, strabismus, and colour vision deficiency may help identify patients at increased risk.
Social and Occupational History
A patient’s lifestyle and occupation can significantly influence both the development and impact of ophthalmic conditions. In terms of risk factors, smoking and alcohol use should be explored, alongside occupational hazards such as prolonged screen exposure or risk of eye trauma.
Beyond clinical symptoms, it is also essential to understand how visual problems affect a patient’s daily life. Difficulties with driving, reading, or navigating familiar environments may indicate significant functional impairment and provide valuable insight into the severity of the condition.
Furthermore, certain ophthalmic conditions may affect a patient’s ability to drive safely, either temporarily or permanently, making it crucial that patients are appropriately counselled.
Finally, understanding a patient’s living circumstances and access to healthcare offers important context for ongoing management, including the feasibility of follow-up and adherence to treatment.
Review of Systems
A brief but targeted review of systems can reveal important clues to underlying systemic disease, with ocular manifestations. Generalised symptoms such as weight loss or fatigue can point towards an underlying systemic disease with ocular manifestations. Symptoms such as joint pain or skin rashes may point towards autoimmune conditions. Conversely, respiratory symptoms could suggest diseases such as sarcoidosis or tuberculosis.
As previously mentioned, neurological symptoms are particularly important to exclude as their presence may indicate optic neuritis or cerebrovascular events, which may require urgent neurological imaging, assessment, and treatment.
Communication Tips and Asking Big Questions Effectively
Taking an effective ophthalmology history relies not only on structure but also on effective communication skills. Beginning with open-ended questions allows patients to share their experiences freely before the clinician narrows the focus to more specific details.
Avoiding medical jargon, maintaining a clear and empathetic approach, and periodically summarising information all help to ensure accuracy and build patient trust. Importantly, clinicians should focus on gathering information that will directly influence clinical decision-making and urgency.
Conclusion
A structured ophthalmology history is essential for accurate diagnosis and effective patient care. By systematically exploring the presenting complaint, associated symptoms, past history, and wider health and social context, clinicians can build a comprehensive understanding of the patient’s condition. Developing confidence in this skill enhances clinical reasoning, ultimately contributing to better patient outcomes.
