Wet macular degeneration, also known as neovascular or exudative AMD (age-related macular degeneration), is a more advanced and severe form of AMD compared to the dry form. It involves the growth of abnormal blood vessels beneath the macula, the central part of the retina responsible for sharp, central vision.

Macular neovascularization (MNV) is a condition characterized by the abnormal growth of new blood vessels in the macula, the central part of the retina responsible for sharp, central vision. This phenomenon is a hallmark feature of wet or neovascular age-related macular degeneration (AMD).
In macular neovascularization:
Macular neovascularization is a significant concern because the abnormal blood vessels can disrupt the normal architecture and function of the macula, which is critical for tasks such as reading, recognizing faces, and seeing fine details.
Early detection of macular neovascularization is crucial for timely intervention and treatment to minimize vision loss. Anti-vascular endothelial growth factor (anti-VEGF) drugs are a common and effective treatment for wet AMD associated with macular neovascularization. These drugs work by inhibiting the growth of new blood vessels and reducing leakage, thus preserving vision and preventing further damage to the macula.
In wet macular degeneration, a macular scar refers to the formation of fibrous tissue or scar tissue in the macula, the central part of the retina responsible for sharp, central vision. The scar tissue develops as a result of the growth of abnormal blood vessels (neovascularization) beneath the macula, which can leak blood and fluid into the surrounding retinal tissues. Over time, as these abnormal vessels leak and heal, they can lead to the formation of scar tissue, replacing the normal retinal architecture.
A macular scar is a late-stage manifestation of wet macular degeneration and is associated with significant and often irreversible vision loss. The scar tissue disrupts the normal structure and function of the macula, leading to distortions and impairments in central vision.
There is no effective medical or surgical treatment to reverse or remove a macular scar once it has formed. The focus of treatment for wet macular degeneration is primarily on preventing the progression of the disease and minimizing further damage to the macula.
However, it’s important to note that research in the field of ophthalmology is ongoing, and there may be developments or new treatment approaches that have emerged since my last update. Additionally, individuals with macular scars may benefit from low-vision rehabilitation services, which can help optimize their remaining vision and enhance their ability to perform daily activities.
If you or someone you know has wet macular degeneration or is concerned about vision changes, it is crucial to consult with an eye care professional for a thorough evaluation and appropriate management. They can provide the most up-to-date information on treatment options and support for vision rehabilitation.
In wet macular degeneration, retinal fluid refers to the abnormal accumulation of fluid within or beneath the retina. This fluid accumulation is a consequence of the growth of abnormal blood vessels (neovascularization) beneath the macula, which can leak blood and fluid into the surrounding retinal tissues. The presence of retinal fluid can contribute to vision distortion and, if left untreated, may lead to irreversible vision loss.
There are two main types of retinal fluid associated with wet macular degeneration:
The presence of retinal fluid is typically identified through imaging techniques such as optical coherence tomography (OCT). Monitoring the extent and characteristics of retinal fluid is crucial in the management of wet macular degeneration.
Treatment for wet macular degeneration often involves anti-vascular endothelial growth factor (anti-VEGF) drugs, which are injected into the eye to inhibit the growth of abnormal blood vessels and reduce the leakage of fluid. These treatments aim to minimize the accumulation of retinal fluid, preserve vision, and prevent further damage to the macula.
Regular eye exams and imaging tests are essential for monitoring the presence of retinal fluid and adjusting the treatment plan as needed to optimize visual outcomes for individuals with wet macular degeneration.
A pigment epithelial detachment (PED) is a characteristic feature observed in certain cases of wet macular degeneration, particularly in the context of neovascular or exudative age-related macular degeneration (AMD). A PED refers to the separation or detachment of the retinal pigment epithelium (RPE) layer from the underlying structures, often accompanied by the accumulation of fluid or other substances.
Here are key points about pigment epithelial detachments in the context of wet macular degeneration:
It’s important to note that not all cases of wet macular degeneration involve pigment epithelial detachments, and the severity and characteristics can vary among individuals. Regular eye examinations, including imaging studies, are crucial for the accurate diagnosis and management of wet AMD, including conditions like pigment epithelial detachment. Individualized treatment plans are developed based on the specific features observed in each case.
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular or wet age-related macular degeneration (AMD) that is characterized by abnormal blood vessel growth in the choroid, which is the vascular layer beneath the retina. PCV is considered a distinct entity within the spectrum of neovascular AMD, and it has some unique features that differentiate it from other forms of wet macular degeneration.
Key characteristics of polypoidal choroidal vasculopathy include:
Treatment Approach: The treatment of polypoidal choroidal vasculopathy may involve a combination of approaches, and it can be different from the standard treatments for other types of wet AMD. The two main treatment modalities include:
It’s important to note that the choice of treatment for PCV is individualized, and decisions are based on factors such as the characteristics of the condition, the extent of polypoidal lesions, and the patient’s overall health. The field of ophthalmology continues to evolve, and new research may influence treatment approaches for PCV over time. Patients with PCV should consult with their eye care professionals for a comprehensive evaluation and personalized treatment plan.
A submacular hemorrhage in wet macular degeneration refers to the accumulation of blood beneath the macula, the central part of the retina responsible for sharp, central vision. This condition can occur as a complication of abnormal blood vessel growth associated with wet or neovascular age-related macular degeneration (AMD).
Characteristics of Submacular Hemorrhage:
The choice of treatment depends on factors such as the size and location of the submacular hemorrhage, the overall health of the eye, and the patient’s individual circumstances. It’s crucial for individuals with submacular hemorrhage to consult with their eye care professionals for a comprehensive evaluation and to discuss the potential risks and benefits of each treatment option. Early intervention is often key to optimizing visual outcomes in cases of submacular hemorrhage.
