Flashes, many new floaters, or a curtain over the vision is an eye emergency.
Report new distortion, a central blind spot, or sudden vision change promptly.
New central distortion or sudden vision loss requires urgent assessment.
Severe pain, redness, light sensitivity, or worsening sight after an injection also needs urgent care.
Follow-up depends on the AMD stage, symptoms, imaging, and treatment plan.
Early or intermediate dry AMD may be monitored through routine dilated examinations, while geographic atrophy and wet AMD often require more frequent visits and imaging.

Keep appointments even if vision seems unchanged because OCT may detect changes before symptoms develop.
Between visits:
Check each eye separately as instructed.
Use an Amsler grid if recommended.
Continue prescribed injections and monitoring unless your clinician advises otherwise.
Bring an updated medicine and supplement list to appointments.
