Macular degeneration is a chronic eye disease that typically causes blurred central vision, distorted images, and dark spots in the central visual field. The primary cause of macular degeneration is the gradual aging of the eye over time, hence it is often referred to as age-related macular degeneration.
However, some young people may develop macular degeneration due to other factors. So, with current medical technology, are there viable treatment options for macular degeneration? Can some forms of macular degeneration resolve on their own? The following will explain the causes and treatment methods of macular degeneration.
Causes of Macular Degeneration
Age-related macular degeneration has multiple causes, with the primary factor being age-related changes. It is the leading cause of central vision loss in individuals aged 50 and above. However, some younger individuals may also develop macular degeneration, potentially due to congenital genetic factors or acquired unhealthy habits. Other causes of macular degeneration include:
- Smoking: Studies show that smokers have a 3 to 4 times higher risk of developing macular degeneration compared to the general population.
- Poor dietary habits: Long-term consumption of high-fat, high-sugar foods leads to obesity and the "three highs" (high blood pressure, high blood sugar, high cholesterol), compromising the health of eye blood vessels and increasing the risk of macular degeneration.
- Prolonged exposure to intense sunlight: UVA rays in sunlight accelerate the aging of photoreceptor cells, leading to macular degeneration.
- Cellular Growth Factor Effects: Certain genetic abnormalities in the human body are associated with macular degeneration, such as complement factor B and complement factor H. These genetic abnormalities have been proven to be highly correlated with the progression of macular degeneration.
Additionally, while it's rumored that blue light from electronic devices may contribute to the younger onset of age-related macular degeneration, there currently isn't sufficient research data to substantiate this claim. However, using electronic devices in dimly lit environments may cause the macula to absorb more blue light, potentially triggering various eye conditions.
Will macular degeneration improve?
Some patients ask, "Will surgery for macular degeneration help?" or "Will macular edema resolve on its own?"
It is important to understand that macular degeneration cannot resolve on its own. Treatment options are available to slow the progression of the disease and alleviate its symptoms. To prevent further vision loss, it is recommended to seek prompt medical attention from an ophthalmologist for the treatment of macular degeneration.
What surgical treatment options are available for age-related macular degeneration?
Laser surgery and injections are available treatments for macular degeneration. The cost of these procedures depends on the specific treatment plan. Since macular degeneration symptoms may affect only one eye initially or develop in both eyes sequentially, the cost of treatment—whether laser or injection—will vary accordingly.
Currently, intravitreal injections are the most common treatment for age-related macular degeneration. For patients with more severe cases, doctors may recommend surgical intervention to treat macular degeneration.
Additionally, most treatment plans for age-related macular degeneration focus on the more severe wet form. For dry age-related macular degeneration, doctors typically recommend patients increase their intake of eye-healthy foods or supplements, quit smoking and other unhealthy habits, and undergo regular check-ups.
Laser photocoagulation
Laser photocoagulation can treat not only age-related macular degeneration but also other eye conditions such as cataracts. It works by using the laser's thermal energy to eliminate abnormal blood vessels in the eye, thereby reducing vascular leakage and halting vision deterioration. However, photocoagulation for macular degeneration may damage healthy tissue. If the abnormal vessels are located very close to the center of the macula, alternative treatment options are recommended.
Photodynamic Therapy
Photodynamic therapy combines medication and laser treatment for age-related macular degeneration. An ophthalmologist first injects a photosensitizing solution into the patient's arm. This solution circulates through the bloodstream and attaches to abnormally proliferating blood vessels. A cold laser is then used to activate the photosensitizing solution, which eliminates the proliferating blood vessels in the eye, thereby treating age-related macular degeneration.Unlike laser photocoagulation, photodynamic therapy does not damage surrounding ocular tissues and can also help improve vision issues.

Anti-VEGF Intravitreal Injection
Intraocular injections are the most common treatment for macular degeneration. An ophthalmologist administers a local anesthetic to the surface of the eye before injecting anti-vascular endothelial growth factor (VEGF) medication. This blocks the growth of abnormal blood vessels, thereby reducing the risk of bleeding from new blood vessels. The injection therapy not only controls the progression of macular degeneration but also improves impaired vision. It is particularly effective for treating wet macular degeneration.
Another method for treating wet macular degeneration involves intravitreal steroid injections. Long-acting steroids effectively reduce damage to the retinal barrier caused by abnormal blood vessels within the eye and improve macular edema. However, it is important to note that steroids may cause other eye problems such as increased intraocular pressure and cataracts.
New Technology for Treating Advanced Age-Related Macular Degeneration
When laser treatment or injections fail to cure macular degeneration, ophthalmologists typically recommend supplementary methods to help patients improve their vision. These include implanting a bifocal intraocular lens or wearing low-vision glasses. Although such approaches may be more expensive than surgical treatments for macular degeneration, they offer a relatively direct and rapid solution.
Low Vision Glasses
Smart low-vision glasses instantly project images of the surrounding environment onto the healthiest areas of the retina for individuals with low vision, adjusting based on the patient's perception. These glasses enhance the patient's perception of real-world scenes by supplementing and correcting visual details. During setup, ophthalmologists can intuitively calibrate the glasses to help patients achieve optimal vision.
Bifocal Intraocular Lens
SML (Scharioth Macular Lens) is an implantable lens that helps patients "magnify" their visual field. Featuring a specially designed central optical zone, it provides a high additional hyperopic power of +10.0D, improving near vision without compromising distance vision.
Will some macular degeneration improve after surgery?
Unfortunately, macular degeneration cannot be completely cured. Whether undergoing macular degeneration surgery or other treatment options, they can only slightly improve vision and prevent further deterioration.The key lies in prevention. Daily care for eye health is essential: minimize direct exposure to bright light, supplement with nutrients like lutein, and strive to slow the aging process of the eye. Only then can the risk of developing macular degeneration be reduced.
Diet and Care After Macular Degeneration Surgery
Diet and care after macular degeneration surgery are critical steps that directly impact the success rate of the procedure. Following surgery or injections, certain precautions must be observed. For instance, it is essential to strictly adhere to the doctor's instructions regarding the timing of eye drops or oral medication. In daily life, avoid rubbing your eyes, reduce eye strain, and steer clear of environments with high smoke or dust levels, such as construction sites or areas with heavy smoking.
Regarding diet, it is recommended to ensure nutritional balance and increase intake of foods rich in vitamins C, E, A, and zinc, such as dark leafy greens, fruits, and nuts. Doctors typically advise patients to focus on supplementing vitamin C post-surgery, as it aids in accelerating recovery and preventing infections; lutein is recommended as part of long-term health maintenance following macular degeneration surgery.Additionally, patients may consider adopting dietary approaches for macular degeneration recommended by ophthalmologists or nutritionists to maintain healthy vision.
If a patient develops age-related macular degeneration due to high blood pressure, high blood sugar, high cholesterol, or other health issues, they must modify their diet and lifestyle. Only a healthy body can prevent the macular degeneration from worsening again and reduce the risk of recurrence.
Frequently Asked Questions
In most cases, macular degeneration surgery does not require hospitalization. Typically, macular degeneration procedures are performed on an outpatient basis, allowing patients to return home the same day for rest and follow-up appointments as scheduled. However, in some instances, the doctor may decide whether hospitalization for observation is necessary based on the patient's specific condition.
Most macular surgeries do not require hospitalization. Recovery time after macular disease surgery varies from person to person. Doctors will provide specific recommendations based on the type of surgery and the patient's condition.
The effectiveness of macular degeneration treatment varies from person to person, depending on the severity of the condition and the timeliness of treatment. Some cases may improve with treatment but will not disappear completely.
One treatment for macular degeneration involves injecting medication into the macula of the eye. This therapy can help control disease progression and improve vision, particularly in early- and mid-stage cases where injections can yield significant results.
