These are some of the diagnostic tests commonly used in eye care. Your specialist will recommend the ones relevant to your evaluation — not every test is required for every patient.
An OCT scan captures detailed cross-sectional images of the retina and optic nerve using light waves, without touching the eye.
It is often used to evaluate retinal conditions and glaucoma. The scan is generally quick and non-invasive; the specialist reviews the images as part of your evaluation.
A fundus examination allows the specialist to view the back of the eye — including the retina, optic nerve and blood vessels — often after dilating drops are applied.
This is a common part of comprehensive eye examinations and diabetic or retinal screening.
This test maps your complete field of vision, including peripheral vision, and is often used to detect or monitor conditions like glaucoma.
During the test, you typically respond when you notice lights appearing at different points, while the machine records your field of vision.
Tonometry measures the pressure inside the eye, a key indicator used in glaucoma screening and monitoring.
The test is brief and is a standard part of most comprehensive eye examinations.
Corneal topography maps the curvature of the cornea’s surface in detail, helping to detect irregularities such as keratoconus or to plan refractive surgery.
It is a non-contact scan that takes only a few moments to complete.
Pachymetry measures corneal thickness, an important factor in glaucoma assessment and in evaluating candidacy for refractive surgery.
It is a quick, straightforward test usually performed as part of a broader evaluation.
Biometry measures the eye’s length and other dimensions, and is most commonly used to calculate the correct intraocular lens (IOL) power before cataract surgery.
This measurement supports accurate surgical planning for cataract procedures.
A slit-lamp is a microscope with a bright light source that allows a specialist to examine the front structures of the eye — including the cornea, iris and lens — in magnified detail.
It is one of the most frequently used tools in a standard eye examination.
Retinal imaging captures photographs of the retina for documentation and to track changes over time.
This is often used alongside other retinal tests, particularly for monitoring diabetic retinopathy or other retinal conditions over successive visits.
The specialist or technician explains the test and its purpose beforehand.
Some tests require dilating drops or brief preparation.
Most diagnostic tests are quick, painless and non-invasive.
Your specialist reviews the results with you and explains next steps.

Most diagnostic eye tests are non-invasive and cause little to no discomfort. Some, like tonometry, involve brief contact or an air-puff sensation, which your specialist will explain beforehand.
Some tests, such as fundus examination, require pupil dilation, which can temporarily blur near vision and increase light sensitivity for a few hours. Your specialist will advise if this applies to you.
Most individual tests take only a few minutes, though a comprehensive evaluation involving several tests may take longer. Your care coordinator can give you a time estimate when booking.
No — your specialist recommends specific tests based on your symptoms, history and the purpose of your evaluation, not a standard fixed panel.
