How Does Glaucoma Affect Vision

Glaucoma is a disorder in which the optic nerve of your eye is damaged. Over time, it worsens. It’s frequently linked to an increase in intraocular pressure. Glaucoma is a disease that runs in families. It is frequently not discovered until later in life. Intraocular pressure, or the pressure inside your eye, can harm your optic nerve, which sends images to your brain. Glaucoma can cause permanent vision loss or perhaps total blindness within a few years if the damage increases.

The majority of persons with glaucoma do not experience any early signs or pain.

Visual Symptoms Reported by Patients with Glaucoma

Glaucoma vision loss has typically been termed as “peripheral vision loss.” By asking patients precise detailed questions about how they see, we hoped to improve our clinical understanding of the visual symptoms induced by glaucoma.

Patients with varied types and stages of glaucoma who were clinically diagnosed were included in the study. All were given a thorough eye examination, which included Octopus visual field testing. If a patient had other ocular disorders that affected their vision, such as cornea, lens, or retina pathologies, these were ruled out. Patients were asked to fill out an oral survey on their visual complaints. We looked at the visual symptoms that glaucoma patients experienced and compared the severity of visual field loss to the visual symptoms they reported.

Ninety-nine patients responded to the survey. Primary open-angle glaucoma was diagnosed in the majority of patients (76 percent). All patients, including those with early or intermediate glaucoma, reported a need for additional light and hazy vision as the most common symptoms. Patients with larger field loss (Octopus mean defect >+9.4 dB) were more likely to have trouble seeing objects to one or both sides, as if looking through filthy glasses, and trouble distinguishing boundaries and colours.

What Does Vision Look Like With Glaucoma?

The following are the most common visual complaints described by glaucoma patients:

  • More light is required.
  • Vision is blurry.
  • Recognizing glare
  • Peripheral vision impairment
  • Contrast is difficult to distinguish.

How Long Does It Take For Glaucoma To Affect Vision?

Glaucoma takes about 10-15 years to progress from early damage to ultimate blindness if left untreated. It takes 15 years to progress from a 21-25 mmHg IOP to a 25-30 mmHg IOP, seven years to progress from a 25-30 mmHg IOP to a pressure greater than 30 mmHg, and three years to progress from a pressure greater than 30 mmHg IOP.

Does Glaucoma Cause Blurry Vision?

The typical understanding of glaucoma sufferers’ vision loss as loss of peripheral vision is not accurate. The most prevalent symptoms described by glaucoma patients were a need for more light and impaired vision.

How Can I Improve My Vision With Glaucoma?

These suggestions may aid in the management of high eye pressure or the promotion of eye health.

  • Maintain a balanced diet. A nutritious diet can help you stay healthy, but it won’t stop your glaucoma from getting worse.
  • Exercise in a safe manner.
  • Caffeine should be consumed in moderation.
  • Drink plenty of water.
  • Sleeping with your head raised is a good idea.
  • Take the medication as directed.


Glaucoma cannot be prevented. However, if you catch it early enough, you can reduce your chance of eye injury. Maintain a regular eye exam schedule. The earlier your doctor detects glaucoma symptoms, the sooner you can begin treatment. Every 3 to 5 years, all adults should get their eyes tested for glaucoma. Get a full eye checkup from an eye doctor every 1 to 2 years if you’re over 40 and have a family history of the condition. If you have diabetes or are at risk for other eye illnesses, you may need to visit more frequently.
