Age-Related Macular Degeneration: How Is It Detected and Managed?

What is AMD?

The macula is the central part of the retina used for reading, recognizing faces and seeing fine detail. In AMD, macular tissue gradually becomes dysfunctional while peripheral vision is often preserved.

Small deposits called drusen may appear in early disease. Drusen do not mean that severe vision loss is inevitable, but they make monitoring and risk assessment important.

Symptoms patients may notice

Symptoms can include central blur, difficulty reading despite updated glasses, faded colors or a need for brighter light. Straight lines may look wavy, or a small part of a word may seem missing.

Cover one eye at a time while reading or using an Amsler grid if your clinician recommends it. Home monitoring does not diagnose AMD, but a new change should trigger an eye examination.

How is AMD diagnosed?

Assessment starts with a dilated retinal examination. OCT provides cross-sectional images of the macula, while fluorescein angiography or OCT angiography may be used when abnormal vessels or leakage are suspected.

The key question is not only whether AMD is present, but which stage and phenotype is present and whether there is active disease requiring prompt treatment. Visual acuity alone is not enough for that decision.

Dry AMD, geographic atrophy and wet AMD

Dry AMD is the most common form and may remain stable or progress slowly. Geographic atrophy refers to areas where retinal cells are lost; specialist treatment is discussed according to lesion location, stage and risk profile.

Wet AMD involves abnormal blood vessels beneath the retina that can leak or bleed. Anti-VEGF injections are the main treatment for many active cases and require planned monitoring. The medication and interval are individualized by a retina specialist.

Treatment and protecting vision

For selected stages of dry AMD, a clinician may discuss an AREDS2 formulation. Supplements are not appropriate for everyone and can interact with smoking status or medical conditions, so do not start them without staging and medical advice.

Stopping smoking, controlling blood pressure and diabetes, staying active and eating a balanced diet rich in vegetables support general and retinal health. UV-blocking sunglasses and scheduled follow-up remain useful even when symptoms are mild.

When is it urgent?

New line distortion, a central gray or dark spot, or sudden central vision loss can indicate active neovascular disease and needs urgent assessment. Do not wait for a routine appointment or drive if vision is unsafe.

Frequently asked questions

Does AMD cause complete blindness?

It mainly affects central vision, while peripheral vision is often retained. The impact varies by type, stage and treatment response, which is why early monitoring matters.

Is there an eye drop that cures AMD?

No home eye drop restores damaged macular cells. Active wet AMD may need injections, while dry AMD is managed according to stage and risk.

Does every patient need AREDS2 supplements?

No. Benefit is linked to specific AMD stages and supplements may be unsuitable for some people. Discuss them with a retina clinician.

Can AMD have no symptoms?

Yes, particularly in early stages. Retinal examination and imaging can detect changes before obvious vision loss.
