Understanding Glaucoma: Shedding Light on Vision Loss


Vision is one of our most precious senses, yet conditions like glaucoma pose a significant threat to it. January is Glaucoma Awareness Month—a time dedicated to educating individuals on the disease. 

What is Glaucoma?

Glaucoma refers to a group of eye diseases that damage the optic nerve, usually due to increased pressure within the eye. It often develops slowly and without noticeable symptoms in its early stages, earning it the nickname "the silent thief of sight." If left untreated, glaucoma can result in irreversible vision loss and even blindness.

Types of Glaucoma

There are several types of glaucoma, but the two primary categories are open-angle and angle-closure glaucoma. Open-angle glaucoma, the most common type, develops gradually and is often painless. Angle-closure glaucoma, on the other hand, occurs suddenly and requires immediate medical attention due to its rapid progression.

Risk Factors

While anyone can develop glaucoma, certain factors may increase the risk:

1. Age: Individuals over 60 are at higher risk.
2. Family History: Genetics play a role in some types of glaucoma.
3. Medical Conditions: Diabetes, high blood pressure, and heart disease may elevate the risk.
4. Eye Conditions: Severe nearsightedness, eye injuries, and thin corneas may increase risk.

Symptoms and Diagnosis

Early glaucoma typically doesn't exhibit noticeable symptoms, making regular eye exams crucial for early detection. As the condition progresses, symptoms may include peripheral vision loss, tunnel vision, eye pain, blurred vision, and seeing halos around lights.

Diagnosis often involves comprehensive eye exams that measure intraocular pressure, examine the optic nerve, assess peripheral vision (visual field tests), and sometimes utilize imaging tests like OCTs (Optical coherence tomography).


Treatment and Management

Although there's no cure for glaucoma, early detection and treatment can help slow its progression and prevent further vision loss. Treatment options include prescription eye drops, oral medications, laser therapy, and surgical procedures. The surgeons at Talley Eye Institute utilize a range of glaucoma treatments, to include the latest in minimally invasive glaucoma surgery (MIGS) and treatment technologies. Learn more about glaucoma and treatment options here: https://www.talleyeyeinstitute.com/glaucoma


Education about glaucoma is crucial in preventing vision loss. Regular eye check-ups, especially for individuals over 40 or those with risk factors, can aid in early detection.

Dangers of eye rubbing, and how to avoid it

25 Mar, 2021
‘Tis the season for sniffing, sneezing, and itching. Along with the beauties of spring, we have the inevitable onset of seasonal allergies and all the delightful symptoms that brings. Eye rubbing is such a common occurrence this time of year but can wreak havoc on your eyes for many reasons. • First off, we always urge people to keep hands away from the eyes because rubbing can actually deform, or warp your corneas. Eye rubbing is one of the leading causes of a sight-threatening disease called Keratoconus. More on that topic soon! • GERMS! Your hands carry more germs than any other part of your body and rubbing the eyes can spread those germs and lead to infection. • With airborne pollen and allergens this time of year from blooming trees and flora, it’s easy to get a foreign body in your eye. If you rub when there is something in your eye it can lead to corneal abrasions or other corneal damage. But how do I stop rubbing, you may ask. Rubbing the eyes is so common that we often don’t even realize we’re doing it! Here are some quick tips and tricks to help prevent rubbing. • If there is ever something in your eye, flush the eye with saline solution or artificial tears. Don’t try to pick it out with your fingers or rub the eye. You can also try gently lifting the lid and rolling your eye around a bit, then dabbing gently in the corner of your eye with a clean tissue. • Keep your eyes well lubricated with a good quality artificial tear. Anything that claims to “get the red out” is not good for your eyes, avoid these types of drops. • If you have seasonal allergies, talk with your optometrist about a good allergy drop that can help alleviate the itchiness. • Wear a good set of sunglasses outside. Always a good idea, but it may also help with keeping your hands away from your eyes when outdoors. • If you wear contact lenses, be sure you remove them daily to clean them and allow the eye to “breathe”. Never sleep in your contacts and always change them out according to schedule.

iStent inject W offers hope for those with glaucoma and cataracts

By Stephanie Georges • 09 Nov, 2020
The iStent is a trabecular micro-bypass system implanted at the time of cataract surgery to treat mild-to-moderate primary open-angle glaucoma. The surgeons at Talley Eye Institute began using the original iStent in 2017, upgrading to the iStent Inject in 2019, and finally to the latest iStent inject W in 2020. Dr. Dwight Silvera was the first to implant the iStent inject W in the region. Representing the next generation of the trabecular micro-bypass technology, the iStent inject W provides greater stability of the stent, a more streamlined procedure with better procedural predictability. The iStent inject W is built on a solid, dependable foundation of proven efficacy and safety in thousands of eyes worldwide to reduce eye pressure in adult patients with both cataracts and mild-to-moderate primary open-angle glaucoma. “With iStent inject W, we now have an advanced option that not only effectively manages eye pressure associated with glaucoma but may also reduce our patients’ reliance on glaucoma medication,” said Dr. Silvera. The iStent inject W stents are one of the smallest medical devices known to be implanted in the human body. When inserted into the eye, these tiny stents create two bypasses, or openings, between the front part of the eye and its natural drainage passageway, restoring the eye’s natural ability to drain fluid. For patients managing their glaucoma with medication and are now preparing for cataract surgery, the iStent inject W may be an ideal option. Talk with your doctor to learn if iStent inject W is right for you.
