Vision changes can be alarming, especially when they happen slowly over time. Conditions like glaucoma and age‑related macular degeneration (AMD) are two of the most common causes of vision loss in adults, and both can develop silently before noticeable symptoms appear. Regular eye exams are essential for detecting these conditions early, before they lead to irreversible vision loss.
Understanding the early signs and differences between glaucoma and macular degeneration empowers you to protect your sight. This guide explains what each condition is, typical symptoms, and why scheduling a professional evaluation at Lakeside Vision in Hawley is crucial.
What Are Glaucoma and Macular Degeneration?
Glaucoma
Glaucoma refers to a group of eye diseases that damage the optic nerve — the cable that connects the eye to the brain. This damage is often related to elevated intraocular pressure. Over time, untreated glaucoma leads to peripheral (side) vision loss, and eventually, central vision loss. Because early glaucoma may not cause symptoms, many people don’t realize they have it until it has progressed significantly. (Mayo Clinic)
Macular Degeneration
Age‑related macular degeneration (AMD) affects the macula — the central part of the retina responsible for sharp, detailed vision. When the macula deteriorates, you may notice blurriness or distortion in the center of your vision. AMD is the leading cause of central vision loss in people over age 60.

Both conditions can occur in one or both eyes and may progress slowly, which is why early and regular screening is so important. A comprehensive eye exam is the most reliable way to detect early signs before noticeable vision loss occurs.
Early Signs of Glaucoma
One of the most concerning aspects of glaucoma is its ability to develop without early symptoms. In many cases, vision changes only appear after the optic nerve has already been significantly damaged. (Mayo Clinic)
Watch for these indicators:
- Gradual loss of peripheral (side) vision
- Difficulty adjusting from dark to light environments
- Halos or rainbow‑colored rings around lights
- Redness or eye pain (more common in acute types)
- Severe headache or nausea with eye pain (acute angle‑closure glaucoma)
Because open‑angle glaucoma — the most common form — may cause no early symptoms, eye pressure testing and optic nerve evaluation during a Comprehensive Eye Exam are vital for early detection.
Glaucoma treatment focuses on lowering eye pressure to slow or prevent further nerve damage. This may include prescription eye drops, laser therapy, or surgery depending on disease severity.
Early Signs of Macular Degeneration
AMD typically affects central vision first. The changes can be subtle at the start, and many people don’t notice symptoms until the condition has progressed. (Lakeside Vision and Optical)
Common early symptoms include:
- Blurred or fuzzy central vision
- Distorted lines or shapes (straight lines appear wavy)
- Dark or empty areas in the center of vision
- Colors appear less vibrant or faded
In early AMD, symptoms may be barely noticeable. Simple tools like an Amsler grid during your eye exam can reveal central vision distortion long before you recognize it on your own. If changes are present, a consult with a specialist experienced in macular degeneration care helps guide personalized monitoring or treatment.

How These Conditions Differ
Although both glaucoma and AMD are age‑related eye conditions, they affect different parts of the eye and cause distinct types of vision loss.
| Condition | Affected Area | Early Vision Change |
|---|---|---|
| Glaucoma | Optic nerve | Peripheral vision loss first |
| Macular Degeneration | Retina (macula) | Central vision blurs or distorts |
Unlike routine refractive vision changes, neither disease’s early symptoms typically improve with new glasses. Both require clinical assessment and monitoring as part of a comprehensive eye health program.
Why Early Detection Matters
Because glaucoma and macular degeneration can progress without noticeable symptoms, many patients are unaware they have a serious eye disease until vision loss has already begun. Early detection dramatically increases the number of treatment options and the likelihood of preserving vision. (Mayo Clinic)
At Lakeside Vision, we use advanced diagnostic technology to screen for glaucoma, AMD, and other ocular diseases during every eye exam. These evaluations include measurements of eye pressure, imaging of the retina and optic nerve, and functional vision testing.
You can learn about this in detail during your next Comprehensive Eye Exam.
Who Is at Risk?
Though anyone can develop glaucoma or AMD, certain factors increase your risk:
Risk factors for glaucoma:
- Family history of glaucoma
- Age over 60
- High intraocular pressure
- African, Hispanic, or Asian ancestry
- History of eye trauma
Risk factors for macular degeneration:
- Age over 50
- Smoking
- Family history of AMD
- Cardiovascular disease
- Light eye color
Regular exams become increasingly important as you age, especially if you have risk factors for either condition.
Advanced Care and Treatment Options
Glaucoma Management
Treatment for glaucoma focuses on preserving the optic nerve and slowing disease progression. Depending on how advanced the case is, options include:
- Prescription eye drops to lower eye pressure
- Laser procedures to improve fluid drainage
- Minimally invasive glaucoma surgery (MIGS) or traditional surgery
Your eye doctor at Lakeside Vision & Optical will determine the best plan based on the type and severity of glaucoma.
Macular Degeneration Care
While AMD can’t be reversed once vision loss begins, early intervention can significantly slow progression and preserve functional vision. Management options may include:
- Nutritional supplements with AREDS2 formula
- Injection therapy for wet AMD
- Lifestyle recommendations to protect eye health
Your personalized plan is tailored through ongoing monitoring and imaging of the macula.
What Happens at Your Eye Exam
During a visit for early signs of glaucoma or macular degeneration, your exam may include:
- Visual acuity testing
- Intraocular pressure measurement
- Retinal imaging and OCT scans
- Peripheral vision testing
- Amsler grid for central vision distortion
A comprehensive exam at Lakeside Vision allows your doctor to detect subtle changes in eye structure and function before symptoms worsen. Access our full list of preventive and disease‑focused care through our eye care services in Plano.
When to Seek Immediate Care
Contact your eye doctor promptly if you experience:
- Sudden changes in vision
- New dark spots or shadows
- Rapid distortion of central vision
- Severe eye pain or headache with vision changes
These symptoms may indicate acute eye conditions that require urgent evaluation.
Protecting Your Vision in Hawley
Vision preservation begins with awareness and early detection. Glaucoma and AMD don’t always cause noticeable symptoms in their early stages, and that’s why annual comprehensive eye exams are essential. Detecting subtle changes early gives your eye care team the best chance to protect your vision for years to come.
Schedule your eye exam with Lakeside Vision today to get screened for glaucoma, macular degeneration, and other age‑related eye conditions. Your vision is too important to wait.
