Ophthalmologist's Report: How to Read the Eye Doctor's Notes

You're holding a sheet with the eye doctor's notes and see a set of letters, numbers, and marks. Let's break down what such a report consists of, what the individual lines mean, and in which cases it's best to clarify the notes with a doctor.

What an ophthalmologist's report consists of

An oculist and an ophthalmologist are the same doctor: ophthalmology studies the eye, its anatomy, physiology, and diseases, and the specialist is called an ophthalmologist, less often an oculist.

That is why the name of the specialty may differ across records, while the substance of the note is the same.

The record is kept separately for each eye. A full examination includes several checks — from visual fields to examination of the fundus; refraction is added if necessary.

The ophthalmologist's entry in the chart

Different lines of the record relate to different eye tests, and each has its own meaning.

If it's unclear which test a number refers to, that's the first reason to ask again.

What the diagnosis and visual acuity values mean

Visual acuity is checked using a chart: you read the symbols from a distance of about 20 feet, that is, roughly 6 meters. The result is recorded separately for each eye — two lines instead of one.

If glasses or lenses are needed, a refraction test is performed: you look through a device with lenses of different powers, and the doctor determines which ones give the clearest vision.

The diagnosis in the report is a short name for the condition. Among the diagnoses are glaucoma, which is detected by visual fields and by pressure inside the eye, cataract and age-related macular degeneration, whose risk is increased by ultraviolet light and smoking, diabetic retinopathy in diabetes, as well as strabismus and amblyopia in children.

Which examinations are hidden behind the record

Behind each line is a specific test. Here is what a full eye examination includes.

• Visual fields — a test that checks peripheral vision; its loss can be a sign of glaucoma.
• Tonometry — measurement of pressure inside the eye, also to look for glaucoma.
• Pupil reaction and eye muscle function — light is shone into the eye and the pupil's response to light is observed, and a object is also followed to assess the muscles that move the eye.
• Fundus examination — the pupils are dilated with drops and the retina, macula, and optic nerve are examined through a magnifying lens.

When to clarify the record with a doctor

Sometimes the report is written correctly but reads like a cipher. Ask during the appointment: what a mark means, which test a number refers to, whether further follow-up is needed and how often.

A separate reason to return to the doctor is a change in symptoms. With blurred vision together with eye pain, flashes of light, black spots, or halos around light sources, you should urgently see a specialist.

The doctor selects the frequency of check-ups based on age, race, risk factors, and general health. With diabetes, an examination is needed every year. Black and African American adults are at increased risk of glaucoma and may start check-ups earlier — this can be asked about with the doctor.

An ophthalmologist's report by itself is not a reason to call an ambulance; 103 or 112 — if vision suddenly disappears or double vision appears.
