Glaucoma is one of the primary causes of permanent blindness in the United States, and early manifest glaucoma trial and monitoring are essential in managing it effectively. Your eye doctor can assess the progression of glaucoma through a series of tests, such as pupil dilation and eye drops to numb your eyes – these assessments should be part of any comprehensive eye exam. Here are some of the common glaucoma staging and progression risk factors.
Family History of Glaucoma
Many positive traits can be passed from generation to generation, from physical features and a sense of humor to medical conditions like glaucoma. Unfortunately, these qualities often go unused or ignored by their respective recipients.
Studies reveal that lifetime risk for hereditary glaucoma increases by 22% among relatives of patients than among controls, making it essential for those living with hereditary glaucoma to ensure that all family members are aware of this elevated risk and undergo screening regularly; doing so could reduce vision loss caused by hereditary glaucoma.
High Intraocular Pressure (IOP)
An increase in intraocular pressure (IOP) is one of the primary risk factors for glaucoma. This occurs when fluid in the eye, known as aqueous humor, can’t drain out regularly and builds up, increasing IOP.
Eye drops are commonly used to reduce intraocular pressure (IOP). Some increase aqueous humor outflow, while others reduce production from the ciliary body or have both effects at work simultaneously.
Structural-functional dissociation is a hallmark of glaucoma progression when structural changes appear without visual symptoms.
Age & Risk Factors for Glaucoma
Age is one of the influential risk factors for progression and glaucoma, increasing incrementally with each passing year. African Americans over 40 and all adults over 60, as well as those who have a family history of the condition, are especially at risk.
Glaucoma, often known as the “silent thief of sight,” makes regular comprehensive eye exams with their ophthalmologist crucial to detect early symptoms and limit further damage. More severe forms can even cause blind spots without showing symptoms, so these exams must take place regularly to protect vision.
How Smoking Raises Glaucoma Risk Factors
Smoking reduces blood flow to the optic nerve, increasing risk factors like diabetes, high blood pressure, and cataracts – as well as hastening its progression in Glaucoma patients. Therefore, quitting smoking should be seen as paramount.
Researchers recently conducted an advanced glaucoma intervention study that demonstrated that smoking history can be used as an accurate predictor of how quickly their RNFL will thin over time. Using OCT imaging, researchers examined the relationship between smoking intensity and rate of progression (assessed via OCT imaging over eight years).
Diabetes & Glaucoma Risk Management
Diabetes alters how the eye functions and poses an increased risk for glaucoma. People living with diabetes are at increased risk for primary open-angle glaucoma, which may lead to vision loss and blindness.
Diabetic retinopathy, an eye condition that damages the macula, increases the risk for glaucoma. It can lead to blurred vision and floating spots or dots, causing visual field abnormalities.
An active diet and regular physical activity are key components to reducing the risk of diabetes-related glaucoma symptoms. Furthermore, maintaining an appropriate blood sugar level and managing your blood pressure are helpful strategies.
Age-Related Macular Degeneration (ARMD)
Age-related macular Degeneration (ARMD) has been linked with several risk factors for glaucoma, including thinner corneas and lower visual acuity. ARMD leads to decreased visual clarity and, ultimately, blindness. It is the leading cause of blindness.
ARMD occurs when the macula at the center of your retinal nerve fiber layer becomes damaged. This damage is often due to the build-up of pressure within your eye that causes blurry and distorted vision. A recent study demonstrated that ARMD was associated with progression to wet glaucoma due to choroidal neovascular membrane formation.
High Blood Pressure with Glaucoma
The Ocular hypertension treatment study shows that fluctuating blood pressure levels, particularly, may increase the risk of developing normal tension glaucoma. This may occur as fluctuations can disrupt the oxygen supply and cause eye tissue damage. Elevated intraocular pressure (IOP) is one glaucoma risk factor; however, some individuals with the condition can have normal or even low pressures.
Glaucoma medications may help lower eye pressure to protect against vision loss. An elevated IOP also predicts whether the condition will progress. Other exam findings, such as age, cornea thickness, optic nerve head cup size measurements, and initial peripheral vision test scores, may also play a key role.
Age-Related Macular Degeneration (ARMD)
Though the exact pathophysiology of ARMD remains unknown, it has long been associated with progression to glaucoma in some patients. Numerous factors may play a role in this progression, including elevated IOP levels, significant diurnal IOP fluctuations, thinner corneas, and specific genetic polymorphisms.
Macular degeneration is a disease that results in loss of central vision. It may manifest either dryly, where vision becomes blurry and distorted, or wetly, when blood vessels grow beneath the retina and release fluid and blood into the macula.
Managing Glaucoma & Eye Injury Risks
Eye injuries can result from accidents, sports activities, or work activities and could potentially lead to glaucoma in severe cases. People living with glaucoma must comply with their treatment plan, such as taking medication and attending follow-up eye appointments, to minimize vision loss and keep progression to a minimum.
Studies have proven this helps, yet some patients need help to comply due to forgetfulness, other priorities, or lack of knowledge. Such issues could make controlling progression challenging, and providing education may help.
Conclusion
Understanding and managing the various risk factors for glaucoma is essential in preventing its progression and minimizing vision loss. Addressing these factors through a proactive and informed approach can help mitigate the devastating effects of glaucoma and improve the quality of life for those affected.
