Dr Mehta has published extensively on macular degeneration management. Additionally, he is actively engaged with clinical trials such as CAPT study.

Wet age-related macular degeneration occurs when abnormal blood vessels form underneath the retina (macula), leaking fluid or bleeding and blurring central vision. Distorted straight lines on an Amsler grid is an accurate way of diagnosing wet AMD.

Laser photo-coagulation

Laser therapy uses lasers to seal leaky blood vessels in the retina while also stopping new ones from growing, helping reduce macula swelling and protecting vision. It may be used alone or combined with medication for treating proliferative diabetic retinopathy.

Your eye care provider may perform this procedure at their office, where you will either sit or lie down and receive drops to dilate (enlarge) your eyes (dilate). Next, they will use a special tool called a slit lamp to focus a beam of light onto the retina using laser technology; some use contact lenses to help aim the light directly onto your retina and focus it there. A laser will create burn spots which limit growth of new blood vessels on your retina while scarring from laser scarring limits new growth of vessels appearing elsewhere on your retinal surface – your eye care provider may utilize various types of lasers during treatment (slit lamps etc):

For leaky blood vessels in your retina known as choroidal neovascular membrane, they will use a laser with either blue or green wavelength and be suitable for use inside of a FAZ. For other parts of the retina where blood vessel leakage exists, an argon red or krypton green laser might be more appropriate; their aim will be to treat as many lesions quickly to minimize further bleeding or retinal detachment risk.

They will use a yellow or orange laser, which can be applied peripherally on your retina and is especially helpful when treating areas outside of the FAZ; however, its effectiveness for treating juxtafoveal neovascularization is reduced since leaking blood vessels are closer to macula, increasing your risk of vision damage.

Your vision may become temporarily clouded after surgery, so it’s important to follow the doctor’s orders and report any problems immediately. Your eye care provider may suggest making adjustments to your diet to ensure adequate nutritional intake, or provide antibacterial medication as preventative measures against infections.

Ask your eye care provider whether macular degeneration treatment could benefit you. They will discuss both risks and benefits before signing a consent form indicating you understand them and agree to take part in it. Keep in mind, however, that even with this procedure it won’t restore all lost vision entirely – you might still experience loss due to macular degeneration.

Photodynamic therapy

Macular degeneration is a progressive condition of the retina at the back of your eye that leads to central vision becoming blurrier and less distinct, often impacting both eyes at different rates. Although reading small print and seeing fine details becomes harder with time due to light-sensing cells within your macula no longer working effectively over time, your peripheral or side vision remains undamaged and peripheral blindness rarely results.

85-90% of cases of age-related macular degeneration fall under the category of dry AMD, which is marked by yellow deposits called drusen appearing under the retina. While small deposits called drusen may be normal at times, when their size or frequency increases this can indicate progression of disease. About 10% of these cases progress further into wet macular degeneration which involves abnormal blood vessels that leak fluid or blood into macula, damaging its tissue directly.

Photodynamic therapy, which involves injecting photosensitizing drugs followed by laser destruction of abnormal blood vessels, is an emerging treatment option with promising results in slowing vision loss and in some cases improving it. These drugs called anti-VEGF agents work by blocking protein vascular endothelial growth factor which stimulates new vessel formation; once administered they should be injected directly into the vitreous which fills space inside of an eyeball.

Your doctor may use fluorescein angiography during a dilated eye exam to detect macular degeneration, known as fluorescein angiography. For this procedure, harmless orange-red dye known as Fluorescein is injected into one vein in your arm and flowed through retinal blood vessels before being photographed using special cameras. Any abnormal new blood vessels found will show up as abnormal new vessels on these pictures; additionally your doctor will measure straight-ahead (straight down) vision against an Amsler grid chart to see if this test detects changes within.

Photodynamic therapy has proven its efficacy for treating various conditions, such as early stage squamous cell skin cancer, Barrett’s esophagus, advanced T-cell lymphoma and basal and non-small cell lung cancer. As technology improves, researchers hope to further extend its use by inhibiting organ size-regulating signaling pathways within the body; potentially treating soft-tissue sarcoma as well.

Intravitreal injections

Intravitreal injections involve injecting medication directly into the eye using a small needle through its white portion (sclera). To ensure successful outcomes of this procedure, it should only be undertaken by trained retina specialists; otherwise patients may experience pressure but not pain at the time of injection.

Anti-Vascular Endothelial Growth Factor (VEGF) inhibitors are usually injected into the eye to reduce fluid leakage associated with macular degeneration. Additionally, these drugs can also help treat other pathologies including proliferative diabetic retinopathy, retinal vein occlusion and uveitis.

Persons affected by wet age-related macular degeneration will experience an abrupt decrease in central vision due to abnormal blood vessels forming under the retina and leaking blood into their macula, potentially causing permanent damage over time if left untreated.

Wet AMD may be less prevalent than dry macular degeneration, yet its progression can often occur more rapidly due to abnormal blood vessels that leak into the macula and cause permanent scarring that compromises central vision.

Your eye doctor will use an Amsler grid to detect changes in the macula, while fluorescein angiogram may also be performed in order to observe blood flow within your eyes and look for abnormal new vessels that could form.

Patients receiving injections may notice small black spots moving with eye movement caused by air in their medication and will usually dissipate after several hours. Patients may also experience significant irritation following intravitreal injection, in which case frequent application of preservative-free artificial tears will help soothe eye discomfort until it subsides.

After receiving an injection, it is crucial that any signs of infection such as reddening of the white part of the eye, severe pain or light sensitivity be reported immediately as this could indicate endophthalmitis – an eye infection which if left untreated can result in blindness. Furthermore, it’s wise to refrain from touching your eye after the injection and always wear sunglasses in bright lighting conditions.

Surgery

Age-related macular degeneration (AMD) can damage the macula – the area responsible for sharp central vision – leading to rapid loss of central vision and even blindness in older adults. Wet AMD results from new blood vessels forming beneath the retina (choroidal neovascularization). These blood vessels leak fluid or blood into visual messages sent from your eyes to your brain, disrupting visual messages sent back up into your visual system and leading to central vision loss and leading to blindness in this vulnerable demographic. It is one of the leading causes of blindness among older adults and leads them down this path towards blindness as it occurs through new blood vessel choroidal neovascularization caused by new blood vessel formation beneath retina (choroidal neovascularization), with blood vessels leaking fluid or blood entering the optic nerve causing visual messages being disturbed as visual messages come sent up into your visual system from brain, leading them into your visual system and disturbing visual messages sent up from there and disrupted to your brain causing central vision loss over time and leading up-front in older adults! It’s one of many causes of blindness due to loss! This condition contributes directly to blindness among elderly.

Macular oedema occurs when fluid accumulates in the retina and results in swelling known as macular oedema. Symptoms include waviness in straight lines and blurred central vision; various treatments are available to address macular oedema including laser photo-coagulation, intravitreal injections and surgical procedures to alleviate its symptoms.

Another form of wet AMD occurs when yellow deposits, called drusen, form under the retina. Drusen are deposits composed of proteins and lipids found naturally within our bodies; large drusen may indicate early macular degeneration. With wet AMD, however, drusen transform into fragile blood vessels which bleed frequently disrupting visual signals causing permanent loss of central vision if left untreated; anti-vascular endothelial growth factor (anti-VEGF) drugs like Eylea can be used to counteract its action and prevent its creation in order to stop further disruptions in its formative stages thereby slow down its progress resulting in permanent loss of central vision loss over time.

Undergoing surgery for acute macular degeneration may be an effective treatment option if done prior to suffering significant vision loss. Before going under the knife, however, the risks should be discussed with your physician and all instructions pertaining to preparation and recovery must be strictly followed; smoking should also be stopped while eating a nutritious diet with vitamin supplements may help slow progression of disease; furthermore you should wear sunglasses with UV protection whenever outdoors.

Some experimental treatments include transplanting peripheral retinal tissue from living macula to dead ones and genetic modification to enable cells to regenerate. Although neither have shown measurable improvements in vision for humans yet, they offer hope for treating macular degeneration and other eye diseases in the future.
