What Actually Happens at a Dry Eye Evaluation

Quick Answer: A dry eye evaluation at Eyes On The Lake in Bay View, Milwaukee is a dedicated 30-minute appointment, separate from a routine eye exam. Dr. Vaugn Schneider runs about twelve tests, including tear film, blink video, eyelid tone, staining, MMP-9 inflammation testing, a Demodex check and gland imaging, then reviews your results with you in the room.

Most people arrive at a dry eye evaluation with the same two feelings. Relief that someone is finally going to look properly — and a quiet worry that they are about to be sold something expensive.

So here is exactly what happens, start to finish, including the part at the end where you might say no. The appointment is a 30-minute slot; the practice works hard to be efficient and respect your time.

Why this is its own appointment

A routine eye exam checks your vision and your eye health broadly. It is not built to evaluate the ocular surface, and there is not enough time in it to do so properly.

A dry eye evaluation is a different appointment with a different purpose. Usually we schedule it after something has already come up — either you mentioned symptoms, or Dr. Schneider saw something on your eye surface during a regular exam that deserved a closer look. (If you're not sure whether your symptoms point to dry eye, start with the signs people most often miss.)

The goal is not to confirm that you have dry eye. It is to find out which kind, and what specifically is driving it. Those are different questions with different answers, and the treatment follows from the answer. We explain why dry eye usually comes down to three different failure points, each with its own fix.

The twelve things we measure

How your eyes actually feel. We start with the SPEED questionnaire — a standardized measure of dry eye symptoms. It gives us a number we can track over time, so six months from now we are comparing scores rather than memories.

How much tear you have. Tear meniscus height measures the little reservoir of tear that sits along your lower lid. It tells us whether volume is part of your problem.

What your tears are made of. Tear quality looks at the composition — particularly the oil layer, which is what stops your tears evaporating.

How fast your tear film breaks up. Tear break-up time is exactly what it sounds like. We watch how long your tear film stays intact after a blink. A healthy film generally holds for about ten seconds or more; in dry eye it often breaks up much sooner.

How you blink. We film it. Blink rate — how often — and blink efficacy — whether your lids actually close all the way. Dr. Schneider also asks you to close your eyes and hold them closed; commonly, the lids begin to separate and drift open after a few seconds. She shows you the video. Incomplete blinking is far more common than people realize, especially in anyone who works at a screen, and it means the bottom portion of your eye never gets resurfaced. It isn't part of a routine eye exam, so many people have never had it measured.

How your eyelids hold up. We test eyelid laxity and strength. Your lids are the pump that moves oil out of the glands and spreads it across your eye. When they loosen with age, that pump weakens.

Where the surface is damaged. Two dyes — sodium fluorescein and lissamine green — reveal damage to the cornea and conjunctiva that is invisible otherwise. This is where we see how much the dryness has actually cost you.

Whether there is active inflammation. MMP-9 testing detects an inflammatory marker on the ocular surface. It matters because inflammation drives a cycle: inflamed lids produce bad oil, bad oil means unstable tears, unstable tears inflame the surface further. If MMP-9 is positive, breaking that cycle becomes a priority.

What your glands look like. Meibomian gland imaging photographs the gland structure inside your upper and lower eyelids using infrared light, on our CA-800 imager. The instrument calculates the percentage of gland loss, and Dr. Schneider reviews that result with you in the exam room. It is usually the moment the whole thing becomes real for people — because glands that have shortened or disappeared are visible. Research is under way into bringing damaged glands back, but today the best treatments rely on early intervention: preserving the gland tissue you still have and getting it working again.

What comes out of them. We express the glands under pressure and watch what emerges, gland by gland. Clear oil is what we want. Cloudy, thick, toothpaste-consistency, or nothing at all tells us where you are.

A physical exam of the lid margins. We look for blepharitis, telangiectasia — small visible blood vessels along the lash line — crusting, and collarettes. And we always check the lashes for Demodex, the tiny mites that are a common, treatable contributor to lid inflammation.

A real conversation about your life. Long hours at a screen. A fan blowing on you at night. CPAP. Preserved drops used too often. A dusty workplace. Dry hospital air. Known allergies. Food sensitivities, gut health, omega intake. Autoimmune disease, chemotherapy, hormonal changes, and the long list of medications that cause dryness.

That last one is not filler. A meaningful share of dry eye is being driven by something on that list, and no device fixes a cause that is still running. If your history points toward something systemic, such as Sjögren's or a thyroid condition, Dr. Schneider refers you out for the right testing.

Then we sit down and go through it

Dr. Schneider reviews the findings with you — the images, the numbers, what each one means, and how they fit together. Then you get a personalized plan covering both in-office treatment and what you do at home. There is no fixed recipe; the plan follows what your evaluation found.

You are not asked to decide in the chair. If you are ready and eager to start, and there is same-day availability, the team does its best to begin treatment that day.

"It took years for their eyes to get to the stage they are at now, so it will take time and effort on both our parts to get them back to a healthy and comfortable baseline. Some will feel relief much faster, some will take longer. What I can tell them honestly is what I expect, based on their specific disease level." — Dr. Vaugn Schneider, OD, CFMP, Eyes On The Lake, Bay View

What happens if you decide not to treat

Some patients aren't ready. That is a completely reasonable position, and here is what we do about it.

You start with at-home care, and Dr. Schneider sets up a follow-up appointment so she can see whether the at-home therapy is making an impact. And that is genuinely it — no pressure to change your mind. If you change your mind sooner, there's no need to wait: call and come in.

The one thing she will say plainly is that dry eye is a chronic, progressive disease. It will not resolve on its own, and if things start to change further, monitoring is how she can step in. That is why the follow-up matters even when treating isn't on the table yet.

When you are ready, she is ready.

How long it takes, what to bring, and how to prepare

It's a 30-minute appointment. That covers the testing, a review of your images and results with Dr. Schneider, and your plan.

Bring:

• Every eye drop you use — the prescriptions, the artificial tears, the ones in the bathroom drawer you gave up on.

• A full list of your medications and supplements.

• Your glasses, plus your lens case if you wear contacts (handy if you start treatment the same day).

• A rough note of when your symptoms started and what makes them worse.

• Any previous eye records you have.

Contact lenses: there's no contact lens requirement for the evaluation itself.

Driving: pupils are not dilated at this visit, so you can drive yourself home.

Cost: the evaluation can be billed to in-network medical insurance or paid out of pocket, and HSA/FSA funds can be used. Our team looks up your benefits before your visit, so you know what to expect. In-office treatments are HSA/FSA eligible.
