Glaucoma is a slowly progressing problem. On an average, untreated Glaucoma takes around 10-15 years to advance from early damage to total blindness. With an IOP (Intraocular Pressure) of 21-25 mmHg it takes 15 yrs to progress, an IOP of 25-30 mmHg around seven years and pressure more than 30 mmHg takes three years.
Untreated glaucoma can progress to blindness within several years. Acute angle-closure glaucoma is a less common form that can impair vision much more quickly. Early diagnosis and treatment usually results in excellent success and saved vision.
While there is no cure for glaucoma, people experiencing the condition can enjoy a normal, active, and fulfilling life by keeping the condition under control to slow or prevent vision loss.
What Is Acute Angle Closure Glaucoma? This serious condition makes the pressure inside your eye (your doctor may call it intraocular pressure, or IOP) go up suddenly. It can rise within a matter of hours. It happens when fluid in your eye can't drain the way it should.
The most common type is primary open-angle glaucoma, with age as a factor in its progression. Over the years, the person's eye drainage system becomes obstructed, causing inadequate fluid outflow from the eye and eventually causing a progressive increase in IOP.
By the time you notice vision loss from glaucoma, it's too late. The lost vision cannot be restored, and it's very likely you may experience additional vision loss, even after glaucoma treatment begins.
Patients with glaucoma have a normal life expectancy and, with treatment, can carry out activities as they did before diagnosis.
stages: stage 0 (normal visual field), stage I (early), stage II (moderate), stage III (advanced), stage IV (severe), and stage V (end-stage). Staging criteria are based mainly on the HVF, with MD as the primary measure.
In the worst-case scenario, stress can trigger an attack of acute angle-closure (also called narrow-angle) glaucoma. Angle-closure glaucoma is a medical emergency that requires immediate treatment to prevent vision loss.
Glaucoma is indeed a potentially blinding disease. Worldwide, it is the second most common cause for irreversible blindness. However, with early diagnosis and modern treatment, blindness is very uncommon.
What's the most common age for developing glaucoma? You are most at risk for developing glaucoma if you are 40 years old or older. But that's not to say that this is the only time you can develop glaucoma. Like any other health condition, anyone can develop glaucoma.
In addition to avoiding caffeine, saturated fats, trans fatty acids, and salt in your daily diet, glaucoma patients should also consider avoiding any foods they're allergic to. Some of these lifestyle choices might be difficult to make, but they're more than worth it when maintaining eye health.

Glaucoma is a leading cause of blindness
And unfortunately approximately 10% of people with glaucoma who receive proper treatment still experience loss of vision.
Most eyes do not suffer disease progression at rates that may lead to future visual impairment. However, between 3 and 17% of eyes progress at rates of loss that could lead to perimetric blindness within 20 years.
Defining advanced glaucoma
This Glaucoma Staging Codes (GSC) categorisation considers glaucoma to be advanced if there is evidence of glaucomatous optic disc and visual field (VF) loss in both upper and lower hemifields and/or a defect encroaching within 5° of fixation.
Central corneal thickness is a non-modifiable risk factor and the most robust factor in the development of glaucoma.
Stage 1: Glaucoma begins with any alteration to your drainage system, which leads to increased intraocular pressure.
If you are in a high-risk group, get a comprehensive dilated eye exam to catch glaucoma early and start treatment. Prescription eye drops can stop glaucoma from progressing. Your eye care specialist will recommend how often to return for follow-up exams.
Lowering eye pressure can slow down or stop glaucoma progression. Many patients fail to take their glaucoma medications as prescribed. It's vital that you take the drops exactly as prescribed by your doctor. If you don't, they could do you more harm than good.
Normal eye pressure ranges from 12-21 mm Hg, and eye pressure of greater than 21 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension. High eye pressure alone does not cause glaucoma.
Untreated glaucoma can lead to the faster development of permanent vision loss or blindness. Treatments can slow down additional vision loss, but they can't restore lost vision. It's important to see an eye doctor right away if you have eye pain, severe headaches or vision problems.
The Blue Mountains Eye Study found an age‐standardised all case mortality of 24.3% in persons with glaucoma and 23.8% in those without glaucoma nine years after initial evaluation. In our study, 29.8% of our patients with glaucoma died within 10 years of diagnosis; most as a consequence of vascular disease.
