Most glaucoma damage happens between visits.

GlaucoSim brings the full clinical glaucoma exam (visual field, acuity, contrast sensitivity, anterior segment, quality of life, and contactless acoustic IOP screening) into the patient's home, on devices they already own. Continuous, voice-guided, longitudinal.

01 · The clinical gap

Glaucoma
is monitored
like it's static.

Standard care treats progression as a snapshot taken every six to twelve months. Between visits, clinicians rely on patient self-report, single-point IOP measurements, and a treatment plan whose adherence is invisible. The result: late detection of progression, and vision loss that was preventable.

"What happened
between
the last visit
and today?"

  1. 01
    Visual field progression goes undetected for months.
    A new scotoma can emerge weeks after the last in-clinic perimetry, and only gets caught at the next scheduled exam.
  2. 02
    IOP is sampled at one moment in time.
    Diurnal IOP variation can exceed 10 mmHg. Office tonometry samples a single window, frequently the wrong one.
  3. 03
    Adherence is inferred, not measured.
    ~50% of newly-diagnosed patients discontinue medication within months. Clinicians find out when the next field shows progression.
  4. 04
    Quality of life is rarely tracked over time.
    NEI VFQ-25 is validated but seldom administered longitudinally, even though it captures the patient-side reality the perimeter misses.
  5. 05
    Patients can't see their own data.
    Without visibility into their own progression and adherence, there is no behavioral feedback loop.
02 · The platform

The full clinical exam,
self-administered,
at home.

Six tests, voice-guided, calibrated to the patient's own device. No specialized hardware. No clinic appointment required. Each result feeds into a longitudinal record that the treating physician can review on a single dashboard, sorted by progression risk.

Standard

Visual field

24-2 protocol with adaptive thresholding, voice-guided. Pre-rendered point list compatible with standard automated perimetry.

Reliability indices · Per-quadrant MD
Standard E F P

Visual acuity

Logarithmic chart adapted to the device's true pixel density via DPI calibration. Snellen, E-game, HOTV, Landolt-C variants.

Per-eye logMAR · Confidence band
Standard

Contrast sensitivity

Pelli-Robson-style protocol. Detects functional impairment that visual acuity misses entirely, an early glaucoma signature.

Log CS score · Norm-referenced
Standard

Anterior segment

Five gaze positions per eye captured with the smartphone's rear camera and continuous flash. Iris diameter and palpebral fissure scaled in millimeters.

Standardized · Reviewable as MP4
Standard

NEI VFQ-25

Mangione 2001 validated quality-of-life questionnaire, monthly. Captures the patient-side functional impact that perimetry misses.

12 subscales · Composite trend
Contactless

IOP · acoustic

A contactless IOP screening method: a low-frequency sweep excites the eye globe and the front camera tracks sub-pixel iris vibration. Resonance frequency relates to scleral stiffness, which relates to intraocular pressure.

04 · Reliable in any environment

Clinic-grade conditions,
in any room.

On-device machine learning keeps the test environment controlled in real time. Face-mesh tracking, pixel-level photometry and gaze monitoring enforce the same protocol every session, on the patient's own device, without a clinician in the room. The same exam, calibrated to whatever screen, distance and lighting the patient has.

Working distance

Face-mesh-anchored distance estimation enforces the target working distance per take. Per-patient calibration tightens the band on the first frame so optotype size, perimetric eccentricity and acoustic geometry stay constant across sessions.

Live mm · Per-take gate

Cover detection

Pixel-brightness analysis confirms the contralateral eye is properly occluded during every monocular test. The patient gets real-time feedback when the cover slips, so each acuity, perimetry and contrast trial stays truly monocular.

Per-frame · Real-time prompt

Ambient luminance

Front-camera photometry checks ambient luminance before every session and throughout each take. Tests gate behind a luminance window so contrast measurements, perimetric thresholds and optotype legibility stay reproducible regardless of room lighting.

Pre-take check · In-take monitoring

Fixation & gaze

Continuous gaze tracking flags fixation losses during perimetry and confirms the patient is looking at the camera during anterior-segment recording. Reliability indices sit next to every visual-field result, the way clinicians expect to read them.

Fixation losses · False-positive index
05 · The science

Built on peer-reviewed
foundations.

Every test in the platform is grounded in published clinical or biophysical research. We cite the underlying studies for each component (the disease burden, the validated protocols, and the biophysics behind the contactless IOP signal) so clinicians can audit what we built on, not just what we claim.

06 · Built for both sides

For the treating
physician, and
the patient at home.

Two surfaces, one data model. The treating glaucoma specialist sees longitudinal progression and adherence per patient. The patient gets a guided routine that turns a clinic-grade exam into a few minutes a day, on their own device, with no clinic appointment and no extra hardware.

For the glaucoma specialist.

The dashboard a treating physician opens between appointments to triage who needs attention now.

  • Risk-sorted patient queue
    Patients triaged automatically by recent test variance, missed sessions, and reported symptoms.
  • Longitudinal trend per test
    VF, VA, CS, ext-eye, IOP-β, VFQ-25 plotted on a single timeline per patient. Progression flagged automatically.
  • Adherence visibility
    Drop-taking reminders, symptom logs, side-effect reports. The patient-side data that the next clinic visit usually misses.
  • One-tap clinical PDF per exam
    Each session exports as a clinical PDF in the format your existing EHR can ingest.

For the patient.

A guided home routine that fits between coffee and the morning eye drops. No training, no extra device, no clinic visit.

  • Voice-guided in plain language
    An on-screen avatar walks the patient through every test step. No manual to read, no technician needed.
  • Calibrated to the patient's device
    Screen DPI, working distance, ambient lighting and gaze are auto-detected so the test is the same on a budget Android as on a flagship iPhone.
  • See your own progression
    Patients view their results over time, side-by-side with prior weeks, and share the report with their doctor in one tap.
  • Drop reminders & symptom log
    Daily eye-drop reminders, side-effect logging and symptom check-ins build the adherence signal the clinic visit alone cannot capture.

A clinician who got tired of watching preventable vision loss.

Most glaucoma vision loss is preventable when caught early. The bottleneck has never been the science. It is access. We can detect early progression at home, cheaply, with devices patients already own. The clinic visit can stop being the only datapoint.

Mauro is an ophthalmologist trained in clinical glaucoma management and applied machine learning. GlaucoSim was built to close the gap between scheduled clinic visits (where patient deterioration is finally seen) and the months of progression that happen in between.
