Disciform scars are serious retinal lesions that can lead to significant vision loss, typically due to wet age-related macular degeneration (AMD). Our retina specialists at Specialty Vision are dedicated to providing personalized evaluations and support for those affected by this condition.
A disciform scar is a fibrotic lesion that forms in the macular area of the retina, often as the end result of neovascular changes in wet age-related macular degeneration. This condition represents a significant turning point, as it replaces vital retinal structures, leading to permanent visual impairment. Understanding this condition is essential because it directly impacts central vision, which is crucial for tasks that require fine detail.
At its core, a disciform scar is the outcome of the body’s attempt to repair damage caused by abnormal blood vessel growth beneath the macula. In cases of wet age-related macular degeneration (AMD) or other conditions with choroidal neovascularization (CNV), new but fragile blood vessels grow abnormally through the layers of the retina. These vessels leak fluid, lipids, and blood, which results in damage to both the retinal pigment epithelium (RPE) and the photoreceptors responsible for clear, sharp vision. Over time, the healing response leads to the deposition of fibrous tissue, forming a disc-shaped scar that permanently disrupts the architecture of the macula.
This is the central part of the retina dedicated to high-resolution and color vision. It is the most sensitive area in the retina, allowing us to read, drive, and recognize faces.
The RPE is a layer of pigmented cells that supports the photoreceptors by providing nutrients, removing waste products, and maintaining overall retinal health.
This thin barrier lies between the retina and the choroid and plays a key role in the transport of nutrients and waste products.
Located beneath Bruch’s membrane, the choroid is a complex network of blood vessels that supplies the retina with oxygen and nutrients.
Each of these layers plays a critical role in maintaining vision. When the integrity of these structures is compromised due to abnormal blood vessel behavior, a disciform scar may develop, leading to irreversible visual loss in the center of the field of vision.
In wet AMD, the process begins with the development of abnormal blood vessels from the choroid. These new vessels grow through Bruch’s membrane under or within the retinal pigment epithelium. Because these vessels are not as stable as the normal vasculature, they are prone to leaks.
The fragile nature of these newly formed vessels means that fluid, lipids, and sometimes blood can seep into the retinal layers. This leakage creates pools of fluid and disrupts the structure of the retina and RPE. When blood is involved, it adds an additional layer of complexity to the damage, as the blood components can further irritate and injure the retinal tissue.
In response to the leakage and hemorrhage, the body initiates a healing process. Cells lay down fibrous tissue to try and repair the damage, which eventually organizes into a disc-shaped scar beneath the retina. Unfortunately, this fibrotic tissue replaces vital retinal cells that were once responsible for visual acuity.
Surrounding the scar, the retinal tissue may begin to atrophy, meaning the cells gradually deteriorate and die. This atrophy, coupled with additional pigmentary changes in the retina, can extend the region of vision loss over time.
Although this process is the body’s attempt at healing, the formation of a disciform scar is essentially a dead end concerning visual restoration. The photoreceptors and RPE cells that are replaced by fibrous tissue cannot be recovered, making the resulting vision loss permanent.
During a thorough eye examination, a disciform scar appears as a round or oval, gray-white elevated lesion located in the macula. This area might also show pigment clumping, remnants of subretinal hemorrhage, or lipid exudates surrounding the scar.
At the stage when a disciform scar has developed, neovascular activity has typically ceased. Although this means the active leaking of fluid has stopped, the damage—now in the form of fibrous tissue—remains as a permanent mark on the retina.
These clinical features make it clear that a disciform scar is not simply a temporary setback but a clear indicator of substantial and irreversible damage within the central retina. Our retina specialists emphasize that identifying such changes early can be pivotal in managing overall retinal health.
OCT provides cross-sectional images of the retina, offering detailed information about the structural changes caused by a disciform scar. On OCT, the scar is seen as an elevation of the retina with fibrotic tissue disrupting the normally smooth layers, especially the outer retinal layers that house the photoreceptors.
This imaging method involves injecting a fluorescent dye into the bloodstream and capturing its movement through the eye’s blood vessels. In cases of disciform scarring, FA highlights areas of blocked fluorescence due to previous hemorrhages or shows diffuse staining of the scar tissue. This helps our retina specialists visualize where the fibrosis has replaced healthy tissue and gauge the extent of damage.
By integrating these imaging techniques into clinical assessments, our retina specialists can make a more accurate diagnosis and better understand the progression of the condition, even though the scar itself remains irreversible.
One of the hallmark signs of a disciform scar is a loss of central vision. Patients may notice a blurred spot or a dark area—commonly referred to as a scotoma—in the center of their visual field.
This refers to the distortion of straight lines. For example, words or objects might appear wavy or out of alignment, indicating that the normal curvature of the retina is being altered by the scar tissue.
Patients often find it more difficult to distinguish objects from their background, particularly in low-light conditions. This loss of contrast sensitivity can significantly affect daily activities that require sharp vision.
Changes in the retina may lead to subtle shifts in how colors are perceived, further complicating the task of distinguishing critical details in the environment.
It’s important to note that by the time these symptoms become apparent, considerable damage to the macular region has often taken place. This is why early detection of the underlying CNV and subsequent intervention is so critical. While symptoms such as blurred central vision or distorted lines can be concerning, they serve as essential prompts to consult with our retina specialists before the condition progresses too far.
In highly myopic eyes, CNV may develop, and the resulting disciform scar can mimic those found in wet AMD. The difference lies primarily in the overall refractive error and underlying structural changes in the myopic eye.
This condition can lead to CNV and subsequent disciform scarring. The pattern of scarring and the distribution may vary slightly, but the end result is similar in terms of visual compromise.

Sometimes, the abnormal growth of blood vessels occurs without a clearly identifiable cause, yet the end-stage result can be the formation of a disciform scar.
Certain inherited or systemic conditions can cause breaks in Bruch’s membrane, which predispose the eye to CNV and the eventual development of a disciform scar.
Each of these conditions shares common elements with disciform scarring caused by wet AMD, yet they also have distinguishing features that our retina specialists consider during diagnosis. Differentiating between these conditions can help in tailoring the appropriate monitoring and, when possible, intervention strategies.
One of the most crucial aspects of managing disciform scar is prevention. Once the scar has formed, the damage is irreversible, and the resulting central vision loss is permanent. Early detection of CNV in the context of wet AMD is key to preventing progression to a full-blown disciform scar. When the abnormal vessels are caught early, treatments—particularly anti-VEGF therapies such as ranibizumab or aflibercept—can slow the growth of CNV and reduce the likelihood of bleeding and scarring.
Our retina specialists recommend that patients, especially those at risk for AMD due to age or family history, undergo regular eye exams that include thorough fundus evaluations. Detecting early signs of neovascular activity before scarring ensues offers the best opportunity to preserve central vision. By monitoring changes over time with repeated imaging and clinical examinations, any early leakage or hemorrhage can be identified and managed swiftly.
The very nature of a disciform scar is that it represents a healed stage of injury with permanent replacement of functional retinal cells by fibrous tissue. This means that even if the active neovascular process stops, the scar remains.
While anti-VEGF drugs are effective in controlling new blood vessel growth and fluid leakage in the early stages of wet AMD, they do not have the ability to reverse the damage once a disciform scar has developed.
For patients with established disciform scars, there is a strong focus on low vision rehabilitation. This includes using specialized visual aids and adaptive techniques to help maintain quality of life despite the central vision loss.
The prognosis for patients with a disciform scar is generally guarded, as the resulting central vision loss is permanent. Our retina specialists stress that once this fibrotic change has occurred, the emphasis shifts from restoring vision to helping patients optimize their remaining sight and adjust to their visual limitations. Regular follow-up care becomes essential, both to monitor for any additional retinal changes and to provide supportive services like vision rehabilitation.
Unfortunately, the central vision loss caused by a disciform scar is permanent. While low vision aids may help optimize the remaining peripheral vision, there is no proven treatment to reverse the fibrotic changes.
Disciform scars are primarily caused by the body’s response to leakage and hemorrhage from abnormal blood vessels associated with conditions such as wet AMD. The fibrotic healing process replaces vital retinal tissues, leading to permanent damage.
Prevention focuses on detecting and treating choroidal neovascularization early. By intervening promptly, particularly with anti-VEGF therapies, the progression toward disciform scarring can be slowed or halted before extensive damage occurs.
Techniques like OCT reveal an elevation of the retina with fibrotic tissue and disruption of the outer retinal layers, while fluorescein angiography may show blocked fluorescence or staining of the scar tissue.
These frequently asked questions underscore the importance of regular eye examinations and early intervention. Our retina specialists are always ready to address these concerns and provide clear explanations to patients at every stage of their care.
Devices such as magnifiers, specialized reading glasses, and other adaptive technologies can help maximize the use of remaining vision. Our retina specialists can recommend resources and training programs tailored to each individual’s visual needs.
Vision rehabilitation programs focus on teaching techniques to use peripheral vision more effectively. This can include learning new ways to navigate everyday tasks and acquiring adaptive strategies for reading, driving, and other activities.
Continuous monitoring is essential. Even though the disciform scar itself does not improve, regular follow-up with our retina specialists can help manage any additional complications and provide ongoing support for visual rehabilitation.
Adjusting to changes in vision can be challenging. It is often beneficial to seek support from professionals who specialize in low vision counseling or support groups that provide encouragement and practical advice.
Living with a disciform scar is undoubtedly a significant adjustment. However, with the right support system and adaptive strategies in place, patients can continue to lead fulfilling lives. Our retina specialists are committed to being a trusted partner in this journey, ensuring patients feel informed and supported every step of the way.
