No. Classic dry older aged macular degeneration is progressive at its own rate. The areds vitamin supplement has been shown to slow the progression but nothing so far reverses the damage. You should be followed for this by a retinal specialist.
Probably not. Macular degeneration ir due to damage and atrophy of the macula, the central part of the retina where vision is sharpest. Two types (wet &dry) exist and treatment/ppognosis varies. The dry type is usually more benign and slower to progress. Treatment is aimed at halting progression. It includes smoking cessation as well as vitamin/antioxident supplements.
Very different. There are two general forms: dry accounts for about 85% of cases which is the slow breakdown of macular pigment and vision decrease. The wet form has a more rapid progression with formation of new blood vessels, severe vision loss and occasionally intraocular hemorrhage. There are new medications which can address this.
Subcategory. Divided this way since the treatment is different. Wet forms are currently treated with serial anti-vegf injections. Dry does not have leakage but can lead to geographic atrophy which also permanently decreases vision.
Loss of vision w/age. This is a failure of the maintainance of the health of vessels supplying the critical, central portion of the retina. In the 'wet' form, the vessels leak and can cause sudden, profound vision loss. The dry form vessels slowly dry up, leading to gradual vision loss. Meds to treat the wet form are available and if successful, convert you to the dry form. Use the areds supplement to slow it down.
Not exactly. Both the wet and dry forms of macular degeneration cause decrease in central vision. Distortion is often an early symptom and an amsler grid is a good self screening tool. Vision loss from the dry form is usually slowly progressive and lessor in degree than the wet form which can have very dramatic decrease in vision that is rapid and significant.
Yes and no.. Dry macular degeneration (amd) and wet amd both affect central vision. However, the mechanism by which the loss of vision occurs is different. Dry amd causes pigmentary change and thinning (atrophy) in the tissue, whereas wet amd results from either fluid leakage from blood vessels or actual blood hemorrhage in the tissue. Generally, dry amd causes milder vision loss, and wet amd is more severe.
Eye Exam. Dry and wet AMD are diagnosed by a good Ophthalmic exam. If you have any vision loss or problems, you should be seen by an ophthalmologist or retinal specialist as soon as possible. In the dry form there are changes in the back of the eye readily seen and in the wet form you can have sudden loss of vision which is treatable if seen ASAP.
Maybe. Patients with 5 or more soft drusen in either eye are considered to have "intermediate" amd (age related macular degeneration) and these patients and some more advanced amd benefit from being on areds vitamins (see the nei. Gov website). These includes caretenoids astaxanthin. This has not been definitively shown to delay amd or any other ye disease.
Possible. This is an antioxident supplement, but once damage is done it probably wont help. On the other hand if you dont hve side effects it cannot hurt to try.
Both bad. The dry form is the underpinning to both of these. Wet tends to occur a little younger and can cause a rapid drop in vision. With current injectable medication, much of wet can be reversed and prevented from advancing, . But the dry form underlies it and will carry forth at its own rate. So both are bad.
Wet vs dry macular. They are both bad, but each act differently. Wet macular degeneration can cause a sudden dramatic loss of central vision, but has a treatment available to improve the vision if this happens. Dry macular degeneration is slow and progressive central vision loss over years that is currently irreversible.
Not yet. While there are several medications as well as stem cell and gene therapies that are currently being investigated, no treatment has been proven to be safe and effective for geographic atrophy, the hallmark of dry amd. High dose anti-oxidant vitamin supplementation has been shown to be helpful in preventing the progression to the wet form of macular degeneration when certain early signs are present.
Two types. 1. Dry: areds vitamins, tobacco cessation. 2. Wet: intravitreal injections of anti-vegf molecules like avastin, lucentis, (ranibizumab) or eylea.
