Yes. Wet macular degeneration is the growth of new blood vessels beneath the retina. There are new drugs called veg-f inhibitors when injected into the eye can retard the growth of these damaging blood vessels. It's a good idea to see your ophthalmologist if you suspect you have macular problems.
PDT. Pdt laser and intravitreal injection of anti-vegf.
YES! Intravitreal injections of medications into the eye like avastin, lucentis, (ranibizumab) and eylea. Rarely photodynamic theraopy with visydyne is done (an older, less effective treatment). You must see a retina specialist right away.
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.
Actually types. Stages range from mild to severe. There are two general types: the dry form accounting for about 85% of cases which is generally a slow decrease of central vision. The wet form which is more severe has new blood vessels growing in the macula and generally causes more serious and rapid vision loss.
Yes. Patients who have the start of drusen are considered to have "early" amd. Patients with 5 or more soft drusen in either eye are considered to have "intermediate" amd and these patients benefit from being on areds vitamins (see the nei. Gov website). Advanced amd patients have large areas of dry amd also called geographic atrophy or abnormal growing and leaking blood vessels called "wet amd".
Stages of mac degen. The areds severity scale has been used to classify dry macular degeneration. Wet macular degeneration does not have such linear demarcations. It is categorized into classical cnv and occult cnv. There are several subtypes of occult. There are two variants of amd, (retinal angiomatous proliferation) RAP and pcv (polypoidal choroidal vasculopathy). Findings associated with wet amd are critical.
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.
Many. Many different medical treatments have been discovered. There are two types dry and wet types. Avastin (bevacizumab) is a strong new medication used in the fight against wet macular degeneration.
Anti-angiogenics. A new class of medications called anti-angiogenics are now commonly used to treat wet macular degeneration. This treatment has revolutionized care for these patients. Better diagnostic technology is also helping to diagnose earlier leading to better outcomes.
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.
