What it is
The examination in the office gives a lot of information, but there are things that can only be measured or seen with a test: the exact shape of the cornea, the layers of the retina or the visual field (peripheral vision). Tests record those measurements and make it possible to compare them from one visit to the next.
There is no fixed package of tests: the specialist orders only the ones that answer the specific question about each eye. Most of them cause no pain and do not touch the eye, and some require dilating the pupil.
Techniques and procedures
-
01
Corneal topography and tomography
They map the curvature and thickness of the cornea. They are the basis for detecting keratoconus and for deciding whether someone is a candidate for refractive surgery.
-
02
Optical coherence tomography (OCT)
It shows the layers of the retina and optic nerve in cross section without touching the eye. It is used in macular degeneration, macular edema and glaucoma follow-up.
-
03
Visual field
It measures how far each eye sees to the sides. It is the test that shows whether glaucoma has already taken part of the peripheral vision and whether it is still progressing.
Who treats it
When to get checked
- Your ophthalmologist ordered a test to confirm or rule out a diagnosis.
- You want to know whether you are a candidate for refractive surgery.
- You are being followed for glaucoma, retina or keratoconus and it is time to compare.
- You are preparing for cataract surgery and the eye needs to be measured.
If any of these sound familiar, the sensible step is an assessment: that is where you find out what is going on and what to do about it.
General guidance. It does not replace an assessment by a specialist.

Notes
What is worth knowing about your eyes

Am I a candidate for refractive surgery?
It is not for everyone, or at any point in life: first we check your prescription, your corneal shape and the ocular surface.

Diabetes: your retina gets checked even if you see well
The damage starts without symptoms and shows up in a dilated exam, so the check-up is scheduled instead of waiting for trouble.

Glaucoma gives almost no warning
Side vision goes little by little and the brain fills in what is missing. By the time you notice, the optic nerve is damaged.

The cornea is the window of the eye
When it loses clarity or changes shape, vision blurs even with the right lenses: a prescription that will not settle deserves an exam.

Floaters, flashes and shadows
A sudden burst of them, or a shadow moving in from the side, should not wait for your next visit: it calls for a prompt retina exam.

If glaucoma runs in your family
Your check-ups start earlier. Pressure alone is not enough: the optic nerve and the visual field are assessed too, and repeated over time.

Dry eye: why it burns and what helps
It is rarely a lack of water: usually the tear film evaporates too fast. That is why drops alone are not always enough.

After retina surgery
Vision takes time to settle and the follow-up visits are part of the treatment, not paperwork: that is where we see if things are going where they should.

Glaucoma drops are for every day
They are not felt and they do not relieve a symptom: that is why they get forgotten. What they do is hold the pressure while the nerve holds on.

Frequently asked questions
What people ask us most before their first visit
Do I need a referral to book a visit?
No. You can book your consultation directly. If another doctor referred you, please bring their notes and any tests: they help us avoid repeating work that is already done.
How long does the first assessment take?
Between 30 and 60 minutes. It includes a full eye exam.
What should I bring to my appointment?
Your current glasses, a list of the medications you take and any previous eye tests or prescriptions. If you wear contact lenses, ask us how long before the visit you should take them out.
Will my pupils be dilated? Can I drive afterwards?
Often yes, especially for retina and glaucoma exams. The drops leave your vision blurry and light-sensitive for a couple of hours, so it is best to bring someone along or not drive back.
Where is the clinic?
In Santa Fe, inside an office tower: Prolongación Vasco de Quiroga 4001, Tower A, 5th floor, office 5. Allow a few minutes for the entrance and the elevator; the "Directions" button opens the route on the map.
