Macular degeneration is a progressive eye condition that causes central vision loss over time, while usually leaving peripheral (side) vision unaffected.

Age causes the macula of each eye to gradually thin and small protein deposits known as drusen to form. Over time, central vision becomes blurry while straight lines may begin to appear crooked or wavy.

Early Symptoms

AMD symptoms occur when the central portion of your retina, called the macula, begins to degenerate. You may notice gradual changes to your central vision; straight lines may become crooked or wavy; this affects activities such as driving and reading. If these symptoms arise, make an appointment with your eye care professional immediately – earlier detection means faster correction, potentially saving sight.

Macular degeneration comes in two varieties, wet and dry. Dry macular degeneration occurs when your macula thins with age and protein clumps known as drusen form underneath your retina – eventually leading to loss of central vision. On the other hand, wet AMD occurs when abnormal blood vessels form under your retina that leak blood or fluid into it and this can progress much more rapidly than dry AMD leading to severe vision loss much more rapidly than expected.

Macular degeneration’s first symptoms are blurriness that worsens over time, including straight lines becoming crooked or wavy and colors becoming less vibrant. You may also observe smaller objects appearing or having difficulty seeing in low light conditions.

Your ophthalmologist can diagnose macular degeneration with the aid of retinal photographs. A thorough exam of your retina is also key; your physician can identify areas with atrophy (dry AMD stage) as well as risk for wet AMD development.

As there is no cure for dry AMD, early diagnosis is key. You can help yourself by eating healthily, not smoking and getting regular exercise; furthermore a special high-dose formulation of antioxidant vitamins and zinc has been found to slow its progress. Furthermore, visiting your ophthalmologist on a regular basis to monitor any changes to your vision that can help us determine the most appropriate treatment option.

Diagnosis

Macular degeneration (AMD) is a progressive condition that impairs central vision. It occurs when the macula of the retina becomes damaged due to oxidative stress or other factors, most commonly in older individuals but occasionally also younger adults. AMD typically leads to permanent loss of central vision and falls into two forms: Dry AMD and Wet AMD. Risk factors associated with AMD include age, smoking and genetics – however other contributors such as poor diet, obesity and cardiovascular disease could increase someone’s chances of contracting AMD as well.

Early symptoms of AMD typically include blurred vision. As it progresses, affected eyes may have trouble seeing fine details in dim light conditions and developing blind spots due to fluid leakage and dead cells collecting under their retinas.

Your eye doctor can detect dry AMD during a regular eye exam by checking for yellow-tinged lesions on the retina called “drusen,” tiny clusters of protein that cause it to thin over time and eventually lead to central vision loss. However, this usually happens slowly.

Wet AMD is more severe and progresses more quickly than dry AMD. Wet AMD occurs when new blood vessels sprout beneath the retina and leak blood or fluid into the macula; this process is known as choroidal neovascularization or CNV and treated through injections into each eye to stop its growth.

Anti-VEGF drugs are the gold standard treatment for wet AMD, stopping new blood vessels from growing within the eye and can be administered in office under local anesthesia. Recently developed treatments include drugs to remove vascular endothelial growth factor (VEGF). Retrotope has developed RT011, an isotopically stabilized form of docosahexaenoic acid (DHA) which can be taken orally and removes VEGF from retina to minimize its harmful effects; preclinical trials suggest this approach as being effective treatment against wet AMD.

Treatment

Macular degeneration (MD) is the gradual deterioration of the macula in an eye that leads to loss of central vision, the leading cause of irreversible blindness among people over 50. There are two forms of macular degeneration; dry and wet macular degeneration. Dry AMD occurs as tiny protein-clumps called drusen form beneath the retina and start growing, damaging macular tissue as they grow larger; eventually these clumps cause retinal swelling and bleeding with blood vessel leakage damaging retinal pigment epithelium (RPE) damage causes straight lines appear crooked or wavy while colors look faded due to damaged retinal pigment epithelium (RPE) damage causing straight lines appear crooked or wavy while colors look faded when viewing straight-on images compared with straight lines when viewing from above or below; wet AMD affects only those 50 years or older than 50; wet AMD affects only people over 50 if blindness becomes irreversible blindness occurs due to retina damage caused by swelling or bleeding beneath retinal tissue beneath retinal tissues eventually leading to retina swelling and bleeding into macular tissue damage caused by bloody retinal pigment epithelium damage leading to retinal swelling/bleeding and bleeding into macular tissues, eventually leading to damage of retinal pigment epithelium damages of RPE damage which causes straight lines/wavy lines/wavy lines/wavy lines/Wavy colors become pale due to damaged RPE cells caused by blood vessel leakage caused by wet AMD will always cause blindness as soon as symptoms emerges will occur sooner rather than other forms causing RPE damage while wet AMD form eventually leading into wet AMD and bleeding into retina causing retina causing retina bleed due to RPE damage damage leading into damaged RPE damages and bleeding caused retina bleedout damage eventually leading onto retina causing retina causing retina bleeding pigment epitheli bleeding then bleeding into bleeding into blood flow and eventually causes color bleed, leading bleed, leaving color fade fade then changes occur more than previously appear as seen due to bleeding will become pale due to blood flow into its course before. causing bleeding then become affected. resulting in many other than its course! causing bleeding then causes it does eventually giving way causing eventually leading. bleed caused by damaged RPE damages causes retinal. causing retina to swelling/bleed or failing because damaged retina bleed caused damage over causing its affected region (RPE damage eventually leading it.) which later leading into later developing later as damage also. causing retina causing eventually bleeding caused caused causing bleeding before. causing retinas. eventually leading to become evident as damage appears bleed when they start. bleed causes it. causing caused due to swelling bleeding caused damage by swelling by eventually causes retina causing swelling bleed bleed when damaged RPE damages eventually leads eventually bleeding so.. causes; causerPE eventually eventually leads bleed.

Wet macular degeneration (WMD), while less common than its dry counterpart AMD, can be more serious. When abnormal blood vessels grow and leak into the eye, macular edema or choroidal neovascularization develop. Left untreated, WMD can lead to vision loss or legal blindness resulting in permanent vision impairment and legal blindness.

If you have wet AMD, your doctor may suggest injecting eye medication that blocks the vascular endothelial growth factor (VEGF). This treatment has been found to slow progression of the condition while improving vision in some patients – though its effect wears off over time.

Research continues into ways to prevent or treat AMD, with regular comprehensive eye exams necessary to detect any changes to your vision. Consuming leafy green vegetables, fish and yellow fruit, nuts and oils rich in omega-3 fatty acids as part of a balanced diet may help lower your risk. UV protective sunglasses can reduce UV-induced damage to eyes. Finally, quitting smoking and decreasing risks such as high blood pressure, heart disease and cholesterol will further lower the chances of AMD occurring.

Risuteganib, an early development drug currently under testing, has demonstrated its efficacy by inhibiting new blood vessel formation associated with wet macular degeneration – potentially filling an unmet medical need and slowing vision loss in this condition.

Prevention

With dry AMD, light-sensing cells in the macula begin to break down over time and gradually blur central vision, increasing blurriness during day-to-day activities and worsening over time. Bright light can reduce this blurriness temporarily but remains an inconvenience; as it progresses people may develop blind spots in one or both eyes as the disease worsens; wet macular degeneration develops more rapidly but has severe long-term consequences; treatment should begin immediately or it could result in complete loss of central vision without effective prevention measures being put in place.

Wet macular degeneration (WMD) is characterized by abnormal blood vessels leaking fluid and leading to macular scarring, and affects 10% to 15% of advanced AMD patients.1 It typically develops due to yellow-brownish fatty deposits underneath the retina known as drusen, atrophy of RPE cells, and expression of Vascular Endothelial Growth Factor (VEGF), stimulating new blood vessel development that leads to wet AMD.

Early treatment of wet AMD may reduce vision loss by stopping abnormal blood vessels from growing. To do so, inject Avastin, Lucentis or Eylea regularly to limit their growth and slow vision loss.2

Preventing macular degeneration requires eating healthily and regularly visiting an ophthalmologist for comprehensive eye exams. Proper nutrition includes including green leafy vegetables and fish along with high amounts of vitamins C, E and beta-carotene in your diet. In order to get maximum protection against macular degeneration it is also vital that regular comprehensive eye exams take place.

People over 65 are at an increased risk for macular degeneration, particularly those with a family history, Caucasian ethnicity, smoking or chronic UV radiation exposure. Individuals at increased risk should visit their ophthalmologist every six months for an eye exam to detect changes to their vision which can be detected using Amsler grids, OCT or fluorescein angiography; such tests can detect neovascularization which is one risk factor leading to wet AMD and identify those at increased risk for it.
