Glaucoma Awareness Week 2024: 5 Common Myths And Facts You Should Know About Glaucoma

Myth 1: Glaucoma only affects the elderly population.

Fact: While the incidence of glaucoma is comparatively higher among older people, it can affect individuals at any age. The increase in intraocular pressure leading to optic nerve damage can be due to multiple factors, like genetics, high blood pressure, diabetes, or eye injuries.

Myth 2: People with perfect vision do not develop glaucoma.

Fact: Anyone can develop glaucoma, no matter how good or perfect their vision is currently. Individuals with 20/20 vision can still develop the disease; that is why glaucoma is known as the ‘Silent Thief of Vision’. Hence, it is important to get your eyes checked, even if you do not have prescription glasses.

Myth 3: Glaucoma only affects one eye.

Fact: Glaucoma can usually develop in both eyes, but pressure often elevates in one eye initially. The gradual increase in intraocular pressure damages the optic nerve, leading to changes in vision. In most cases, our peripheral vision is affected first, and it eventually leads to tunnel vision in the advanced stages.

Myth 4: Excessive screen time and an improper diet raise the risk of glaucoma.

Fact: There's no scientific evidence linking excess screen time and an improper diet to glaucoma. However, myopia (nearsightedness) patients may be at risk.

Myth 5: If you develop glaucoma, you will become blind.

Fact: Glaucoma is the leading cause of preventable blindness. Glaucoma could be prevented with early detection, diagnosis, and prompt treatment. It can be controlled with eye drops and the latest procedures like trabeculoplasty and MIGS (Minimally Invasive Glaucoma Surgery).
