What is Glaucoma?

Glaucoma is a group of eye diseases that cause progressive damage of the optic nerve at the point where it leaves the eye to carry visual information to the brain.

If left untreated, most types of glaucoma progress (without warning nor obvious symptoms to the patient) towards gradually worsening visual damage and may lead to blindness. Once incurred, visual damage is mostly irreversible, and this has led to glaucoma being described as the “silent blinding disease” or the “sneak thief of sight”.

Glaucoma Facts – Worldwide

78 million have glaucoma
111.8 million are predicted to have glaucoma by 2040
Glaucoma is the most common cause of irreversible blindness
In many cases, glaucoma may be asymptomatic, meaning it shows no symptoms; half of those living with glaucoma are unaware that they are affected
Every 1 in 200 people aged 40 have glaucoma, which rises to 1 in 8 by aged 80.
The earlier the diagnosis, the less damage will be done and the more vision will be saved!

Patients don’t see their scotoma!

The patient’s view: no apparent scotoma

“Glaucoma is one of the leading causes of irreversible blindness, but with early treatment, the damage may get limited and sight may be saved.”

Fabian Lerner
President World Glaucoma Association
(2020 – 2021)

“By promoting regular testing, we also want glaucoma patients to get their relatives involved, as the chances of them getting glaucoma are 10 times higher than someone with no glaucoma history in their close family environment.”

Ivan Goldberg
Council Member World Glaucoma Association

That’s how TowardPI supports Eye Specialists

TowardPI OCT has a number of methods and options to offer when it comes to glaucoma screening, follow-up and patient management:
the Biomechanical Glaucoma Factor for early detection of normal tension glaucoma as well as biomechanically corrected intraocular pressure. All this is available from TowardPI.

The TowardPi OCT has a normative database of approximately 1,000 subjects for glaucoma diagnosis, which is the largest in the world. This results in the highest matching accuracy and precision for the most critical glaucoma parameter—RNFL thickness.Combined with its ultra-widefield SLO imaging, it not only enables glaucoma detection but also predicts early-stage glaucoma at an academic level. Why? Traditional glaucoma assessments only evaluate RNFL thickness within a limited area of approximately 6 mm around the optic disc and macula. However, early glaucoma often begins at the peripheral retina. This is where TowardPi OCT stands alone globally—its maximum scan range reaches 24 × 20 mm, several times larger than conventional devices such as Zeiss, allowing it to capture and analyze peripheral RNFL changes that other OCT systems simply cannot detect.
