What is Glaucoma?

Understanding About
Glaucoma

Glaucoma, a group of eye conditions, damages the optic nerve responsible for transmitting visual information to the brain. Typically associated with high eye pressure, glaucoma can also occur with normal pressure. 

While it can affect individuals of any age, it’s more prevalent among older adults, often leading to blindness in those over 60. Many forms of glaucoma show no early warning signs, with vision changes becoming noticeable only in advanced stages.

Regular eye exams, including eye pressure measurements, are crucial for early detection. With timely recognition, vision loss from glaucoma can be slowed or prevented, necessitating lifelong treatment or monitoring for those affected.

FAQS
Glaucoma is caused by high levels of pressure within the eye. This intraocular pressure (IOP) presses on the optic nerve, causing damage, and eventually leading to permanent vision loss.
Glaucoma has been nicknamed the silent thief of sight because it often causes permanent vision loss before the disease is even detected. In its early stages, glaucoma does not typically present with any symptoms that would send you to your eye doctor with complaints of vision changes. Therefore, by the time you see your eye doctor, a large amount of vision loss has already occurred.
f glaucoma is not effectively controlled at an early stage, the disease can cause severe peripheral vision loss— resulting in a condition called ‘tunnel vision’. Tunnel vision blocks your ‘side vision’, and limits your field of vision to strictly seeing images in your central vision, or straight ahead.
Peripheral vision is affected first, and if not effectively controlled at this point, can result in tunnel vision. As the disease progresses, central vision is affected next, leaving the person with partial, or complete permanent vision loss.
Glaucoma affects more than 70 million people, worldwide. Glaucoma is a leading cause of irreversible blindness, and accounts for 12.3% of global blindness. Glaucoma affects up to 5% of adults ages 70 and above, and increases to over 9% for those 80 and older.

Yes, stress can elevate intraocular pressure, which may aggravate glaucoma.

While surgery can significantly lower eye pressure, regular follow-ups are necessary as pressure may fluctuate.

Yes, acute angle-closure glaucoma can develop suddenly and requires emergency treatment.
