History and Documentation

A thorough history often points to the diagnosis before any test is run. The ophthalmic assistant gathers it in a structured order:

Chief complaint (CC) — the reason for the visit, recorded in the patient's own words ("my right eye has been red for three days").

History of present illness (HPI) — characterizes the complaint: onset, duration, severity, location (one eye or both), what makes it better or worse, and associated symptoms (pain, discharge, flashes, floaters).

Past ocular history — prior surgeries, trauma, patching as a child, glasses or contact lens wear.

Medical history, medications, and allergies — systemic disease (diabetes, hypertension, autoimmune disease) affects the eye; always record current medications and drug allergies before any drop is instilled.

Family history — glaucoma, macular degeneration, strabismus, and many corneal dystrophies run in families.

Social and functional history — smoking, occupation and hobbies, driving needs.

At 9% of the exam, History and Documentation is the heaviest single content area on the COA — worth studying in full depth.

Start open-ended — "tell me about the problem" — and let the patient talk. The real concern often surfaces in the first unprompted sentence. Then focus with targeted questions until every dimension is pinned down:

Onset and tempo — sudden (minutes to hours) points toward vascular events and retinal detachment; gradual (months to years) fits cataract, presbyopia, and refractive drift. "When did you first notice it?" beats "has it been a while?"

Laterality — one eye or both? Monocular symptoms localize to that eye or its nerve; binocular symptoms suggest refractive, neurologic, or systemic causes.

Severity — quantify. Pain on a 0–10 scale; vision loss as "can't read street signs" vs "can't count fingers."

Timing and course — constant or intermittent, better or worse through the day, improving or progressing.

Modifying factors — better with blinking (tear film), worse with reading (accommodative or binocular), worse in dim light (cataract, media).

Associated symptoms — pain, redness, discharge, photophobia, halos, headache, flashes, floaters, double vision. The associations are often more diagnostic than the main complaint.

Avoid leading questions — "it doesn't hurt, does it?" contaminates the answer. Ask, then record what the patient actually said.

The history taker is the clinic's early-warning system. These stories get escalated to the physician immediately — not booked into a routine slot:

The assistant does not diagnose — the assistant recognizes the pattern, documents it accurately, and makes sure the doctor hears about it now.

The medication list is clinical gold — take it completely, including over-the-counter drugs and supplements.

Drugs the eye clinic specifically hunts for:

Allergies — record the drug AND the reaction ("penicillin — hives"). A reaction description separates true allergy from intolerance and guides safe substitutes. Confirm allergies before any drop is instilled, every visit.

Systemic disease — for diabetes, capture duration and control (recent A1c): they predict retinopathy better than the diagnosis alone. Hypertension, autoimmune disease (RA, lupus, Sjögren), and thyroid disease all have ocular signatures worth connecting to the visit.

Family history that changes management — glaucoma in a first-degree relative substantially raises risk and lowers the threshold for a full workup; macular degeneration, strabismus and amblyopia, high myopia, and inherited retinal dystrophies (retinitis pigmentosa) all run in families. Ask by disease, not just "any eye problems in the family?"

Social history — smoking is the biggest modifiable risk factor for macular degeneration and worsens thyroid eye disease and cataract; alcohol and recreational drug use affect surgical planning and compliance. Ask routinely and without judgment.

Occupation and hobbies — welding, grinding, and woodworking without safety glasses are foreign-body and burn risks; long screen days drive dryness and accommodative complaints; pilots, drivers, and machinists have visual standards to meet.

Functional demands — does the patient drive at night? Read music? Work at two monitor distances? Night-driving glare trouble is often the first real-world sign of cataract, and the prescription the doctor writes should serve the life the patient actually lives — which the history has to capture first.

The chart is a clinical tool and a legal document. If it isn't documented, it didn't happen.

Write entries that are factual, specific, attributed, and complete: "Patient states vision worsened over 2 weeks; denies pain, flashes, floaters." Never editorialize ("probably exaggerating") — opinions don't belong in the record.

Corrections (paper) — single line through the error so it stays legible, then initials, date, and the correct entry. Never white-out, scribble over, or remove pages.

Late entries (paper or EHR) — label as a late entry or addendum with the date actually written. Backdating or silently editing a signed note is falsification.

Abbreviation safety — OD/OS/OU are standard, but OD also means "once daily," and wrong-eye errors are serious; many clinics require writing "right eye"/"left eye" in full on orders and surgical paperwork. Use only your clinic's approved abbreviation list.

SOAP placement — the history is the S (Subjective); measurements are O; the physician's interpretation is A; next steps are P.

Access and ownership — the practice maintains the record; the care team uses it for treatment; the patient has a legal right to a copy. Browsing charts out of curiosity or discussing them with unauthorized family members violates confidentiality.

Special situations — for children, gather history from the parent while engaging the child; for limited English proficiency, use a qualified medical interpreter, not a family member (and never a minor).
