Introduction
Most students and junior doctors are familiar with the standard medical clerking structure: history, past medical history, examination, investigations, and plan. However, when entering an ophthalmology clinic or casualty, documentation quickly becomes more specialised. Notes are concise, anatomy-driven, laterality-specific, and often incorporate diagrams. Understanding this distinctive style is essential for patient safety and for making the most of an ophthalmology placement (1,2).
Visual Acuity as the “Vital Sign”
In general medicine, observations such as heart rate, blood pressure, respiratory rate, oxygen saturation, and temperature are regarded as vital signs. In ophthalmology, visual acuity (VA) plays a similar role and is always documented first. Each eye must be tested separately, unaided and with correction, and a pinhole test should be included where relevant. If vision is very poor, the descending scale of “count fingers,” “hand movements,” “perception of light,” and “no perception of light” is used (3). Clinical guidelines for ophthalmic referral explicitly state that visual acuity is a mandatory part of documentation, highlighting its importance for diagnosis and triage (4).
Laterality Must Always Be Clear
Ophthalmology differs from many specialties in that laterality must be unambiguous. Every finding, investigation, and treatment must specify right eye (RE) or left eye (LE). Even in bilateral disease, documenting each eye separately is crucial, as pathology is often asymmetric. Errors in laterality have been well documented: Elghrably and Fraser found significant instances of right–left transposition in ophthalmic notes, including in diagrams and consent forms, demonstrating the patient-safety risks of unclear documentation (1).
Anatomy-Based Structure
While general medical notes are often arranged by system (cardiovascular, respiratory, abdominal), ophthalmic examination follows the front-to-back anatomy of the eye. Notes typically begin with external structures (lids, lashes, adnexa), then proceed to the anterior segment (conjunctiva, cornea, anterior chamber, iris, pupil, lens), and finish with the posterior segment (vitreous, optic disc, macula, vessels, retinal periphery). This structured approach ensures consistency across clinicians and reduces the risk of omitting key findings (2).
Use of Abbreviations
Ophthalmology relies heavily on abbreviations that are widely accepted within the specialty but unfamiliar to most juniors. Common examples include VA (visual acuity), IOP (intraocular pressure), AC (anterior chamber), and RAPD (relative afferent pupillary defect). These terms are standardised and facilitate rapid documentation, but they can initially appear cryptic to those outside the field (3).
Visual Documentation
Unlike most medical records, ophthalmic documentation frequently incorporates drawings. Fundus charts, corneal sketches, and schematic diagrams are essential for recording spatial detail, progression of pathology, and communication with colleagues. Retinal drawings, in particular, remain widely used as a complement to written notes and digital imaging, enabling precise localisation of lesions (5). The use of schematic colour-coding in ophthalmology has also been described as a standardised way of conveying complex findings efficiently (2).
Immediate Investigations
In contrast to other specialties where investigations are often ordered and reviewed later, many ophthalmic investigations are carried out and documented during the same clinic visit. Examples include optical coherence tomography (OCT), fundus photography, and visual field testing. Results are usually available immediately and often pasted directly into the patient record, creating a workflow unique to ophthalmology (3,4).
Precision in Management
Ophthalmic prescribing requires exact specification of laterality, frequency, and drug concentration. For example: “G. Chloramphenicol 0.5% qds RE for 1 week.” Omitting laterality risks errors with potentially serious consequences, as shown in studies of outpatient ophthalmic prescribing and laterality documentation (1,4).
