Macular degeneration refers to any condition whereby the macula (the small area at the back of your eye that allows you to clearly perceive details, including needle threading) becomes impaired and leads to blurry central vision or dark or distorted areas in its vicinity. It may cause blurring central vision as well as regions which become darker or distorted over time, eventually leading to blind spots on either side of your field of vision.

Prevailing conditions such as macular degeneration can be identified with a comprehensive dilated eye exam, showing early symptoms such as straight lines that appear wavy or an empty spot in the center of your field of vision.

Drusen

Drusen are yellow deposits found under the retina that are characteristic of macular degeneration. They typically take the form of round dots on retinal pigment epithelium (RPE) with various sizes and may form subretinal deposits with sawtooth patterns on optical coherence tomography (OCT) images. Drusen are most frequently associated with age-related macular degeneration but may also occur as part of other retinal disorders or systemic diseases.

Dry macular degeneration is the most frequent form of macular degeneration, whereby the macula thins with age and small protein deposits called drusen accumulate, slowly impairing vision. While dry macular degeneration does not lead to complete blindness, those living with this condition still maintain useful side or peripheral vision but cannot see fine details clearly in their center of visual field.

Wet macular degeneration occurs when abnormal blood vessels form beneath the retina and release fluid into the eye, causing scarring of retinal tissue and leading to rapid vision loss. While wet macular degeneration may seem less serious at first glance, its symptoms can quickly escalate into serious vision loss if left untreated.

Some individuals with intermediate AMD experience spontaneous drusen regression. Although it has been proven that such regression can prevent progression to wet macular degeneration, these episodes do not seem to prevent progression further than intermediate AMD.

At present, research into new treatments for macular degeneration is ongoing. One promising strategy may involve laser therapy as a potential treatment strategy to decrease risk of neovascularization; if proven effective this could substantially lower blindness risk from macular degeneration.

Researchers have noted that wet macular degeneration is preceded by OCT imaging features including drusen growth, decreased outer nuclear layer/Heinle fiber layer thickness at the drusen apex and intraretinal hyperreflective foci. Researchers hypothesize that multiple factors lead to macular degeneration including lipofuscin accumulation, abnormalities in photoreceptor and RPE cell function disruption and inappropriate complement activation.

Blind Spots

Macular degeneration occurs when your retina (the layer of tissue at the back of your eye that detects light and transmits images to your brain) starts to break down, specifically the macula (responsible for central vision; you need this ability for driving, reading and recognising faces). When this area of retina begins to malfunction, central vision becomes impaired or distorted and you may notice objects appear blurrier or different than expected, although peripheral and side vision usually remains functionally normal.

Dry age-related macular degeneration (ARMD) is the most frequent form of macular degeneration. Symptoms tend to be milder than with wet ARMD and progress slowly over time. Blurry central vision may precede dark or blank spots appearing in your field of view or straight lines becoming crooked or wavy; all caused by damage from aging blood vessels that leak fluid under the retina that causes vision loss over time. The macula can become damaged over time due to age related blood vessel leakage under retina which causes the macula to be damaged through abnormal blood vessel development which allows fluid leakage beneath retina which gradually worsens vision over time causing further vision loss over time and damage occurs from abnormal blood vessel leakage under retina causing damage through ageing blood vessel growth from leakage which leakage under retina causing damage which further degrades vision further worse over time resulting in further vision loss from underneath retina leaking fluid beneath retina which causes vision deterioration over time causing vision loss over time as more fluid leakage leakage underneath retina causes leakage from beneath retina to cause macular damage from abnormal blood vessels which leak fluid under retina, leading to leakage under retina which in turn causes further vision impairment from year after another year’s leakage below retinal surface which in turn causes this leakage to leakage which damage; eventually leading to macular damage to continue worsen vision worse over time due to leakage under retinal damage caused by ageing caused by ageing blood vessel leakage over time due to slow progressing visually over time due to leakage makes its damage over time and this leaking occurs as leakage causes vision damage by leakage caused by ageing blood vessel leakage through leakage from abnormal vessels developing and eventually worsen damage which causes vision leaking under retina which leakage causes further leakage due to more leaking under retina damage from behind retina leakage under retinal leakage due to finally worsening damage over time causing vision worsening under retinal leakage further leakage which eventually worsening due leakage which eventually worsening over time due to leakage through later leakage leaving behind which causes vision worsening under retinal leakage under retinal damage over time leaking which causes leakage then worse over time which leakage then worse. This leaking fluid build up from under retina damage through retinal layers due leaking under retinal surface due to leakage eventually worsens leakage occurs further damage then slow progression leading to worse. causing vision to worsen further worsens over time causing more and worsen causing leakage eventually affect it further worse causing leakage underneath further worsen. causing vision which eventually worsen then eventually leading to finally getting better further worsen further worse than before finally leading allowing. thereby further. causing leakage underneath leaving retina leakage which leakage eventually leaking of fluid underneath retinala leaking which leakage leakage occurs further over time eventually due to more fluid leakage overtime then eventually which gradually worse which also happens gradually due to leakage as leakage beneath. leaking under retina leakage is then worse further leakage by over time which then leakage through than it’s than then caused leakage as result in it all while slow progress this.

Wet macular degeneration (ARMD) is more serious than dry AMD and can lead to sudden vision loss. This occurs when abnormal blood vessels that form as part of this condition leak fluid and scar tissue into the retina, and an Amsler grid test can help detect distortion caused by blind spots within your central vision. You can perform the Amsler grid at home by looking at an image with one eye closed while looking through both lenses simultaneously; you should see distortion immediately.

Patients suffering from wet macular degeneration have access to treatments that can both stall its progress and even help improve vision. One such option involves injecting an anti-VEGF medication that works by decreasing abnormal blood vessel growth while stopping fluid leakage.

Those suffering from wet ARMD should contact us as soon as possible in order to schedule an appointment and early diagnosis is key for avoiding blindness caused by macular degeneration.

Blood Vessels

The macula is a small area in our retina that helps us see fine details clearly, enabling activities such as reading and driving. Macular degeneration refers to any breakdown or degradation in this small region that leads to blurriness, dark areas or distortion in central vision – this condition is commonly known as age-related macular degeneration or AMD but can progress into wet macular degeneration as well.

Wet macular degeneration occurs when abnormal blood vessels form under the retina and leak fluid and blood, leading to sudden worsening of blurry central vision and eventual blind spots. Treatment options for wet ARMD include laser surgery or medication directly into the eye. Medication prescribed to our office inhibits the formation of new blood vessels that cause wet macular degeneration. As such, it may slow or stop further central vision loss while in some instances even improving it – it is therefore crucial that patients seek immediate medical advice should they experience sudden vision loss. At Amsler Vision Institute, we can conduct a test to analyze your central vision with an Amsler Grid – an arrangement of black lines arranged on a graph pattern – as a pain-free laser treatment called Visudyne Photodynamic Therapy to destroy abnormal blood vessels that lead to wet macular degeneration.

Capillaries, which are smaller than both arteries and veins, but larger than capillaries in size. Capillaries can be found throughout the body but are particularly prevalent in spleen, bone marrow, and pituitary gland. Their thin wall makes them more distensible than arteries while larger venules feature stronger walls than fine capillaries.

Macular degeneration’s exact cause remains unknown, although certain risk factors have been identified as contributing to it, including family history of macular degeneration, smoking, high blood pressure, lighter eye color and being farsighted. According to studies, eating foods rich in antioxidants such as carotenoids – specifically lutein and zeaxanthin, two naturally-occurring pigments found in foods like kale, spinach and collard greens as well as nutritional supplements – could reduce one’s chances of macular degeneration development.

Diagnosis

Age related macular degeneration, or ARMD, refers to the gradual degradation of your retina’s central area known as the macula and is the leading cause of severe vision loss among those aged 65 or over. Symptoms may include gradual central vision loss that causes straight lines to appear crooked or wavy as well as colors appearing less vibrant or face recognition becoming difficult. While its exact causes remain unknown, genetic factors, smoking, and age all likely play an influential role.

Normaly, your macula detects fine details in your central visual field such as reading, driving and seeing faces. Macular degeneration is divided into dry or wet forms; dry degeneration being more prevalent. Drusen deposits buildup under the macula can reduce its performance over time leading to progressive central vision loss. Ten to fifteen percent of cases progress to wet macular degeneration where new blood vessels grow beneath retina neovascularization which leak fluid into macula and cause permanent damage which leads to rapid central vision loss.

Wet macular degeneration can be treated using medications that halt abnormal blood vessel growth and stop or reduce leakage from these new vessels. When administered directly into the eye, these injected medications can be very helpful in stabilizing or improving vision – typically given once every month; your doctor will discuss its benefits and risks for you.

Studies have revealed that taking certain antioxidant vitamins can slow the rate of progression to advanced macular degeneration in people who are at risk. Your ophthalmologist can recommend appropriate supplements and schedule regular follow up appointments; in addition, advanced tests like optical coherence tomography (OCT) and fluorescein angiography can provide early diagnosis and care. Furthermore, the Age-Related Macular Degeneration Study found that high doses of specific antioxidants significantly slowed progression for individuals at risk.
