Wet vs dry AMD is the first distinction patients ask about.
Both are forms of age-related macular degeneration, but they behave very differently.
Clear counseling reduces fear and improves follow-up.
What Is Dry AMD
Dry AMD involves drusen and gradual loss of retinal pigment epithelium and photoreceptors.
It accounts for most cases of AMD.
Vision declines slowly over years.
Therefore, many patients notice little at first.
What Is Wet AMD
Wet AMD involves choroidal neovascularization.
New vessels leak fluid and blood under the macula.
Vision can fall within days or weeks.
So wet disease is an emergency (see new treatments for neovascular AMD).

Dry disease causes blur, trouble with dim light and slow central loss.
Wet disease causes distortion, a dark spot or sudden blur.
Straight lines look bent.
Also ask about new symptoms at every visit.
Wet vs Dry AMD on Examination
Dry AMD shows drusen and pigment changes.
Geographic atrophy shows sharply outlined areas of loss.
Wet AMD shows fluid, hemorrhage and exudate.
So the fundus often gives the answer.
Imaging
OCT shows drusen, atrophy and fluid.
Fluorescein angiography shows leakage.
OCT angiography can show new vessels without dye.
Therefore, image any patient with new symptoms.
Progression From Dry to Wet
A sizable minority of eyes with intermediate AMD progress to advanced disease within five years.
Risk rises with large drusen and fellow-eye disease.
Smoking raises the risk.
So monitor high-risk eyes closely.
Home Monitoring
Patients can use an Amsler grid or a home device (see home monitoring devices for AMD).
New distortion should prompt a same-week visit.
Early treatment preserves vision.
Also remind patients to cover each eye separately.
Treatment of Wet AMD
Anti-VEGF injections are the standard.
Ranibizumab, aflibercept, bevacizumab and faricimab all work.
Regular follow-up prevents recurrence.
Therefore, plan long-term care.
Treatment of Dry AMD
No treatment restores lost cells.
AREDS2 supplements slow progression in intermediate disease (see AREDS2 supplements).
Complement inhibitors now slow geographic atrophy growth.
So treatment options are growing.
Lifestyle Advice for Both Forms
Stop smoking, which is the strongest modifiable risk.
Eat a diet rich in leafy vegetables and fish.
Protect the eyes from strong sunlight.
Also control blood pressure.
Low Vision Support
Many patients keep useful peripheral vision.
Magnifiers, lighting and training help daily tasks (see low vision rehabilitation in AMD).
Early referral improves independence.
So do not wait for advanced loss.
Explaining Wet vs Dry AMD to Patients
Use a simple picture of the macula.
Describe dry AMD as a slow wearing down.
Describe wet AMD as leaking new vessels.
Therefore, the urgency of wet disease becomes clear.
Wet vs Dry AMD: Practical Summary
Ask about distortion at every visit and check with OCT.
Treat wet disease at once with anti-VEGF.
Because dry disease can turn wet, teach home checks.
Finally, support lifestyle change.
Pitfalls to Avoid
- Do not tell patients that dry AMD can never turn wet
- Never delay injections in active wet disease
- Avoid ignoring new distortion
- Do not skip smoking cessation advice
Wet vs Dry AMD in the Fellow Eye
Patients with wet AMD in one eye face higher risk in the other.
Monitor the fellow eye closely.
Because early detection matters, teach home checks.
Therefore, schedule frequent visits.
Wet vs Dry AMD and Supplements
AREDS2 supplements help intermediate dry AMD.
They do not treat wet disease directly.
Because supplements vary, recommend the studied formula.
Then explain realistic benefits.
Wet vs Dry AMD and Geographic Atrophy
Geographic atrophy is the advanced dry form.
Complement inhibitors slow the growth of atrophy.
Because treatment needs injections, discuss burdens.
So decide together with the patient.
Wet vs Dry AMD and Driving
Central vision loss affects reading and driving.
Test visual acuity against legal standards.
If vision falls, advise on safe alternatives.
In addition, refer for low vision services.
Wet vs Dry AMD and Anxiety
Fear of blindness is common in AMD.
Honest, hopeful information eases worry.
Because most patients keep useful vision, say so.
Then offer support groups.
Wet vs Dry AMD: Frequently Asked Questions
Patients ask whether diet can reverse AMD.
It cannot, but good habits slow progression.
They ask whether eye injections hurt.
Most feel only pressure, so reassure them.
Wet vs Dry AMD: Practical Summary
If the patient reports new distortion, image the macula at once.
Because wet disease needs fast injections, book the visit within days.
However, reassure patients with dry disease that slow loss is usual.
Finally, repeat the education at every visit.
