Macular degeneration cannot be reversed, but eating foods such as kale and spinach may help slow its progression.

Treatment options for wet macular degeneration typically involve using non-painful laser light therapy to destroy abnormally leaking blood vessels that lead to wet AMD. This form of therapy has proven very successful at halting further vision loss while also increasing quality of life.

Photodynamic Therapy (PDT)

Treatment for wet macular degeneration uses a combination of photosensitizer (such as verteporfin) and low-powered laser to slow or stop vision loss. The combination works by decreasing new blood vessel growth within the eye, thus slowing or stopping vision loss.

Unfortunately, this treatment has its limitations; it only proves successful during the earliest stages of neovascularization, before any permanent damage has been done to the macula, and cannot reverse existing damage.

Studies investigating the use of adjunctive PDT for wet age-related macular degeneration have been performed extensively, with most showing little or no benefit. The largest trial thus far was the Treatment of Age-Related Macular Degeneration with Photodynamic Therapy (TAP) trial which showed that PDT can cut visual acuity decline by half while failing to restore lost vision.

Another disadvantage of PDT is its regular treatment requirements. Patients need to receive several injections of photosensitizer at regular intervals over several months. After which, retinal specialists use laser beams to irradiate any areas that still appear active – taking less than a minute per eye and generally being safe for most individuals.

Recent developments have produced more effective alternatives than photodynamic therapy (PDT), including anti-angiogenic drugs like Macugen, Avastin and Lucentis that suppress new blood vessel formation to reverse some of the visual acuity loss caused by neovascularization. Unfortunately these medications also come with their own side effects such as itching, discomfort, dry mouth red eyes desquamation erythema at injection sites sometimes even erosive pustular dermatosis which could limit market growth of photodynamic therapy market overall.

Anti-VEGF Treatment

Current treatments for wet age-related macular degeneration (neovascular AMD) focus on halting the formation of abnormal blood vessels that could damage vision and lead to permanent eye damage. Anti-VEGF injections intravitreally are an essential element in managing wet AMD, though they are expensive and require frequent clinic visits for monthly treatment, often throughout one’s entire lifetime.

Bevacizumab and ranibizumab, developed as cancer treatments, have become the industry standard when it comes to anti-VEGF therapy. Both can be delivered intravitreally to block new blood vessel formation by blocking interactions between VEGF and its receptors on retinal cells – these revolutionary anti-VEGF treatments have revolutionized treatment of neovascular AMD while helping patients retain vision while continuing daily activities.

However, medications require frequent visits to an eye care clinic for injections and can result in discomfort for some patients. A recent study from a Swedish eye care clinic determined that discomfort was directly correlated to longer intervals between injections; additionally, frequent treatments could significantly lower quality of life.

Investigators analyzed data on 106 patients with wet AMD who were receiving regular intravitreal anti-VEGF injections. Researchers assessed best-corrected visual acuity (BCVA) of each eye before and after intravitreal injection as well as average central macular thickness (CMT) and optical coherence tomography angiography angiography measurements in both eyes. Outer retinal tubulations (ORTs) were examined using spectral-domain optical coherence tomography and OCT angiography; presence or absence of fluid accumulation was recorded by OCT angiography. Furthermore, outcomes for patients included reduced accumulation and an ETDRS letter loss between consecutive injections in their better eye.

Laser Surgery

Laser surgery uses a high energy beam of light to destroy fragile, leaky blood vessels under the retina that form in wet macular degeneration (AMD). The procedure has been shown to slow vision loss in some people diagnosed with wet AMD; however, its success can only be guaranteed if abnormal blood vessels form away from the fovea of macula; otherwise laser therapy could damage surrounding healthy tissue and diminish your vision further.

When performing laser treatments on the retina, surgeons must clearly see both the target lesion and surrounding retinal pigment epithelial (RPE) layer in order to deliver laser heat accurately to its intended site. A variety of factors influence this, such as how well an eye absorbs laser light; pigments found within RPE have different absorption rates; Melanin located within RPE cells as well as choroidal melanocytes have wide spectrums of absorption while hemoglobin and xanthophylls found within inner and outer plexiform layers have narrower spectrums of absorption rates.

New technology now enables surgeons to view retinal pigment epithelial layer cells through laser-induced fluorescence, aiding them in selecting an appropriate wavelength and monitoring effects of treatment. Fluorescence of cell debris within retinal pigment epithelial layer provides key insight as to whether or not their treatment is having its desired impact and possible adverse side effects.

Amsler Grid

People living with dry macular degeneration should use an Amsler grid at home between visits to an eye care practitioner in order to monitor their vision at home and reduce the risk of wet macular degeneration progression and improve visual results through treatment. Doing this regularly has proven very effective.

Wet AMD symptoms tend to appear quickly and suddenly, often associated with distortion in vision – for instance straight lines may become wavy or the words on a page may move up and down the page. Distortions may affect both eyes equally or just one. With time, however, distortion tends to worsen in central field of vision area.

An effective way to diagnose wet macular degeneration is through a comprehensive eye exam, consisting of visual acuity tests, dilated pupil examination, and Amsler grid testing. A visual acuity test measures your ability to see at various distances while the dilated pupil examination can detect fluid or blood under your retina.

An Amsler grid is a simple grid of black and white lines printed either on paper or displayed digitally, suitable for testing eye disorders. To use it effectively, stand 18 inches (40 cm) away from it while covering one eye. Focus your gaze upon its central dot while looking closely at any distortions or missing lines in the grid – then repeat this test using both eyes.

Amsler grids can be used at home to detect macular degeneration and other retinal problems such as cataracts. It’s essential to regularly monitor your vision and report any changes or irregularities to an ophthalmologist for medical advice.

Angiography

Angiography utilizes a special catheter to inject radiopaque dye that highlights blood vessels on x-ray, providing physicians with an overview of blood vessel anatomy and flow within the body for diagnosis and treatment of conditions like narrowed, blocked, damaged arteries or veins. Angiography can be applied across many parts of the body such as head (carotids), heart, lung, kidneys or limbs and serves both diagnostically as well as interventionally for therapeutic treatment purposes.

Wet macular degeneration (WMD) is caused by leakage from abnormal blood vessels that form under the retina, leading to rapid central vision loss and scarring of retinal tissue. Treatment options currently include intravitreal injections of drugs that target VEGF which have shown to improve vision in 30-40% of cases, yet symptoms can still worsen even with treatment. PDT seeks to slow progression by blocking new blood vessel growth using non-toxic photosensitiser activated by red light; PDT improves treatment outcomes even further

This new nanosystem combines dasatinib prodrug and verteporfin photosensitiser into an autonomous drug delivery platform for enhanced effectiveness in treating wet macular degeneration with minimal systemic toxicity. After red light irradiation, di-DAS-VER NPs release their photosensitiser, binding to CNV neovascularisation to induce ROS-mediated occlusion through ROS production and ROS release – providing more efficient therapy with minimal systemic toxicity; using di-DAS-VER platform facilitates other anti-angiogenic agents as well – offering yet another great option for patients suffering from wet macular degeneration.
