Macular degeneration affects the macula, the small central area of the retina that enables sharp central vision and color perception. Most commonly age-related, it can cause blurring of central vision, distortion of straight lines, and difficulty seeing fine detail. This page provides general information, common risk factors, and guidance on which eye specialists to consult. It is for informational purposes and not a substitute for an individual medical assessment.
The macula is a tiny but vital part of the retina responsible for detailed vision and color. Degeneration occurs when retinal cells and supporting tissue change, or when deposits (drusen) build up, reducing macular function. The condition may progress slowly in some people and more rapidly in others, so periodic eye examinations are important to monitor changes early.
Typical signs include a gradual blurring of central vision, straight lines appearing wavy (metamorphopsia), difficulty reading small print, or reduced color contrast. Sudden, marked loss of vision in one eye, the sensation of a curtain across vision, or rapid new distortion are warning signs that require prompt evaluation by an eye clinic or emergency services.
Age is the primary risk factor, but family history, certain genetic predispositions, smoking, poorly controlled chronic diseases, and long-term unprotected sun exposure can raise risk. Helpful general measures include quitting smoking, eating a balanced diet rich in eye-healthy nutrients, wearing UV-protective sunglasses, and keeping regular eye check-ups. These suggestions support eye health but do not replace individualized medical advice.
If macular degeneration is suspected, start with an ophthalmologist (eye doctor). Retina specialists carry out detailed retinal imaging and assessments and can advise on next steps. For people with reduced vision, low-vision services, visual aids, and rehabilitation teams (including ophthalmologists, low-vision therapists, and occupational therapists) can help maintain independence and quality of life.
