What Is Glaucoma and the Effects It Has On Your Eyesight

How Does Glaucoma Damage The Eye?

Low vision or reduced vision commonly known as vision impairment – is a stage where vision cannot be further improved by spectacles or contact lenses. Several eye conditions or low vision diseases may be the cause of vision impairment however Glaucoma is the second leading cause of blindness globally.

Glaucoma can be defined as an eye condition that damages one of the most significant areas in the eye: the optic nerve. It is the result of the build-up pressure (intraocular pressure) in the eye that causes the optic nerve severe and in most cases irreversible damage. The optic nerve is responsible to send images to your brain and if severely damaged or the damage worsens, can be the cause of blindness or vision loss permanently

Most cases of glaucoma have reported little or no early symptoms or pain which makes it imperative to get a regular eye check-up from an eye doctor/specialist. The importance of getting regular checkups is the possibility of an early diagnosis and treatment which can help lower the eye pressure preventing you from long-term vision loss.

An estimate of 3 million people in the U.S are estimated to have glaucoma as reported
by the Glaucoma Research Foundation

What Are Some Of The Risks Associated?

Though there may be many causes associated with glaucoma, experts expressed their failure in identifying what blocks the channels responsible for carrying the fluid inside the eye. Others have also categorized it as a genetic disorder or a genetic disease. More common causes include chemical injury to the eye, blocked blood vessels inside the eye, inflammatory conditions, and eye infection.

Adults over 40 are much more prone to be diagnosed with low vision diseases like glaucoma, in comparison to young adults, children, and infants. People with a family history of eye conditions such as glaucoma are subject to the risk of passing it down the family tree in the form of genetic disorders. Diabetic patients, individuals taking steroid medications such as prednisone, are likely to be diagnosed with glaucoma. Other causes may include injury to the eye/eyes, high blood pressure, heart disease, etc.

Glaucoma is also one of the root causes of central visual field defects, also referred to as “tunnel vision.” Patients diagnosed with glaucoma are likely to face impaired sensitivity to contrast or problems with glare, issues adapting to the dark, ability to see in low light, and even read.

The Affects of Glaucoma on Your Eyesight and Overall Health

There are other dire effects of glaucoma other than loss of vision or low vision. Damage to the optic nerve can severely affect the peripheral vision resulting in tunnel vision (shrinking field of view). Other effects may include patchy blind spots on the sides (peripheral), blurred vision, severe headache, eye pain, nausea, and vomiting, etc.

Several low vision aids and low vision solutions are available in the market e.g. optical and non-optical devices, that cater to individuals suffering from different eye conditions e.g. Glaucoma, Macular Degeneration, etc. The purpose of these devices is to facilitate the vision impaired and low vision individuals to carry out routine tasks seamlessly, making use of the several features available in these devices such as magnification, contrast, reading mode, etc.

Devices ideal for Glaucoma Patient

Are there devices that contain a wide array of useful features like magnification, portability needed to carry out daily tasks, each requiring a special feature? Unfortunately, there aren’t many options. The properties and features of each of the low vision device need to be aligned with eye condition as well as the limitation it causes e.g. magnification devices may not be beneficial for specific glaucoma patients who do not yet have central vision loss, common in very advanced glaucoma.

  • Full-Field Microscope Glasses are described as devices ideal for reading due to its portable feature. For it to be used efficiently, good lighting is a must. These glasses have been criticized for their decreased field of view, making the reading experience a bit problematic.

  • Stand Magnifiers – an alternative to microscope glasses, also suitable for reading. The stand magnifier is more stable than a handheld magnifier but does not include portable features making it less accessible in different settings.

  • Handheld Magnifier is the classic low vision solution for short-term reading e.g. price tags and menus.

  • Electronic Magnifiers also are popularly known as CCTV (closed-circuit television) providing a larger field of view on a monitor, with the option of adjusting the magnification and contrast modes.

  • IrisVision can be categorized as the best low vision aids for glaucoma patients, a wearable headset that provides a 70-degree field of view unmatchable by any other low vision device available globally. The images shown in this portable device are sharp and crisp enhancing the overall visual experience for the vision impaired and glaucoma patients. The ‘RP Mode’ will adjust the entire visual captured focusing to its optimum size allowing you to move it across.

    Easy to charge, wireless charging enablement, and free software updates are just some of the few reasons why IrisVision beats all other low vision aids.

Keeping a regular check on your vision and eye’s health is just as important as visiting the dental clinic to ensure good oral hygiene. The significant increase in the usage of digital mediums and exposure to screens through phones, laptops, desktop computers, televisions demand an even more comprehensive eye care routine as well as health and safety measures. Regular eye checkups and eye exams are highly advisable, as early diagnosis prevents the damage from causing serious, irreversible damage that later may not be treatable.

Seeking help from a specialist or professional council is always a smart choice, as it equips you with risk mitigation strategies and information and that has already been tested and validated. Individuals with low vision can also benefit from different devices (mentioned earlier) such as low vision aids for glaucoma patients, after consulting their respective eye specialists enabling them to perform their daily tasks and reclaiming their independence.
