Degenerative retinoschisis is a common retinal condition affecting many adults. At Specialty Vision, our skilled retina specialists can help you understand its impact on your vision and ensure your eye health is prioritized.
This page provides comprehensive information on degenerative retinoschisis, detailing its nature, impact on vision, diagnostic methods, management strategies, and essential guidance for preserving retinal health.
Degenerative retinoschisis affects approximately 4% of individuals over the age of 40. It is often asymptomatic and discovered incidentally during routine eye examinations.
Degenerative retinoschisis is a condition in which the retina, the light-sensitive tissue at the back of your eye, splits into two distinct layers. This separation primarily affects the outer edges, or the peripheral retina, though in some cases it may occur in the central region. Understanding this condition is essential for those experiencing changes in their vision, and our retina specialists are here to help clarify what it means for your eye health.
When we talk about degenerative retinoschisis, we refer specifically to the acquired form of this retinal disorder. In this condition, the retina essentially divides into separate layers—a process that can compromise how well your eye gathers and transmits visual information. Often seen in patients in their 50s, 60s, and 70s, degenerative retinoschisis is sometimes also known as senile retinoschisis, although it can occasionally develop in younger individuals as well.
This condition is characterized by a split that usually occurs in the peripheral retina, although the central area might also be affected. The retina plays such an important role in turning light into images that travel to your brain, and when its layers separate, the result may be subtle or, in some cases, more noticeable changes in vision.
In degenerative retinoschisis, the term “schisis” comes from the word for split or cleft. Essentially, a part of the retina may separate into two potential layers: one containing the light-sensing cells and the other containing the cells that relay signals to your brain via the optic nerve. The split can follow different patterns and is generally categorized by its appearance. There are two primary subtypes described:
This form is more commonly observed and tends to present with minimal elevation of the retinal layers. As a result, it might not significantly affect your vision right away.
Often referred to as the blistered or raised form, this type features a more pronounced separation and can potentially lead to complications such as retinal holes or even a retinal detachment. The primary difference between these two subtypes lies in the amount of elevation seen in the retinal layers, with the bullous form posing a higher risk for more serious complications.
Our eyes work best when every layer of the retina is correctly aligned to capture light and create clear images. With degenerative retinoschisis, this organized structure is disrupted.
Many people with this form of retinoschisis may not notice any significant symptoms, primarily because the separation often occurs in areas of the retina away from your central vision. However, if the changes become more severe or if the condition affects the edges of your visual field, you might experience issues such as a loss of peripheral vision. In more pronounced cases, some patients describe seeing floaters—small spots or lines that drift in your field of vision—or flashes of light, which can be unsettling on their own.
It’s important to remember that even if you feel your vision hasn’t suffered dramatically, routine examinations can help catch subtle changes early. Our retina specialists stress the importance of these check-ups to ensure we address any potential progression of the condition.
Understanding the signs of degenerative retinoschisis can help you know when it’s time to schedule an eye exam. Even if symptoms seem mild, early evaluation is important for tracking the condition and preventing potential complications. While many people may not notice any symptoms for years, there are several changes that can eventually develop:
As the retinal layers separate, especially in the outer parts of the retina, you may notice difficulty seeing things to the side or a gradual loss of side vision.
You might see tiny spots or shapes floating in your vision or experience brief flashes of light. These can be signs of retinal stress or traction.
Though less common, some people report wavy or bent lines, especially when looking at straight edges or text, indicating possible retinal involvement near the macula.
Some may experience a dim, shadowy patch in their side vision, which can sometimes be mistaken for tired eyes or normal aging.
You may notice it's harder to see in low light or dim conditions, or to distinguish between similar colors and shades.
Retinoschisis may make it harder to see clearly in the dark or while driving at night, especially if peripheral vision is affected.
One of the puzzling aspects of degenerative retinoschisis is that its exact cause remains unclear. Unlike congenital forms of retinoschisis, where a genetic mutation is more evident, the acquired type doesn’t have a well-established origin in the medical community. Researchers continue to investigate why the retina splits, but what we do know is that the risk increases as we age.
This age-related association is why degenerative retinoschisis typically surfaces in people in their 50s, 60s, or 70s. As time goes on, the structural integrity of the vitreous—the gel-like substance in your eye—can change, which might contribute in small part to the onset of the condition. However, it is important to note that while age is a significant factor, not everyone in these age groups will experience degenerative retinoschisis. Factors such as the overall health of the retina and the natural aging process of the eye tissues also play roles.
While the medical community continues to piece together the exact mechanisms behind the retinal split, it is clear that current research emphasizes careful monitoring in at-risk populations to ensure any progression is caught early.
While there is no cure for degenerative retinoschisis, many patients manage its progression through regular monitoring and practical interventions. The first step is always a thorough discussion with our retina specialists who can explain what any changes mean for your vision and how best to proceed.
In many cases, degenerative retinoschisis is considered benign, meaning that it does not significantly impair vision or require aggressive treatment. However, it is essential to remain vigilant, as a small percentage of cases can lead to complications like retinal holes or even retinal detachment. Here are some important considerations when managing this condition:
Frequent check-ups are critical. Even if you are not experiencing any significant symptoms, monitoring your retinal health ensures that any changes are evaluated early.
Many people with retinoschisis benefit from glasses that help correct refractive errors. This adjustment can make a difference in daily visual clarity, even if the underlying structural change remains unaltered.
If your vision begins to change noticeably, specialized low vision aids can help reduce the impact on your daily activities. These devices support better visual performance and improve quality of life.
In the event that the condition progresses to involve retinal holes or detachment, more active intervention may be required. Options such as laser therapy or cryotherapy (cold treatment) might be considered to stabilize the situation. Managing degenerative retinoschisis is all about staying informed and proactive. Our retina specialists always encourage patients to call the office if there are any changes in vision, no matter how small they may seem.

Most individuals diagnosed with degenerative retinoschisis can lead healthy, active lives, especially when the condition does not progress beyond a benign state. Knowing that you have this retinal split might initially cause some concern, but it’s important to remember that not every case requires invasive treatment. Regular follow-up visits can help keep a close eye on the condition without the need for immediate intervention.
For many patients, understanding the difference between retinoschisis and retinal detachment is an important aspect of navigating their eye health. Though they may seem related, these two conditions affect the eye in distinct ways.
Retinal detachment occurs when the entire retina pulls away from the underlying supportive tissue. This can lead to a dramatic and immediate loss of vision, making it a sight-threatening emergency. In contrast, retinoschisis involves a separation within the retina itself, meaning that the layers split but the retinal tissue does not fully detach from its support. This key difference means that while retinal detachment often requires swift surgical intervention, degenerative retinoschisis might be observed over time with regular check-ups.
It is also possible, though less common, for a person to experience both conditions concurrently. When the bullous form of degenerative retinoschisis becomes more pronounced, the likelihood of forming retinal holes increases, and these holes can sometimes lead to a retinal detachment. However, early detection and monitoring can often prevent the transition from a benign split to a more severe detachment. If you’re ever uncertain about changes in your vision, don’t hesitate to discuss them with our retina specialists.
Because the symptoms of degenerative retinoschisis can be subtle, diagnosis is often made during a comprehensive eye exam conducted by our retina specialists. Several specialized tests are typically performed to look closely at the layers of the retina:
Also known as fundoscopy, this test allows the specialist to examine your retina using a specialized instrument called an ophthalmoscope. It offers a direct view of the retina and can sometimes reveal the splits that define retinoschisis.
OCT is a non-invasive imaging technique that uses light waves to create cross-sectional pictures of your retina. This method provides a detailed look at the layers of your retina, helping to distinguish between the different types of retinoschisis.
In cases where the view is hindered or more detail is needed, an ocular ultrasound (B-scan) may be used to get clear images of the retina’s structure.
This test records the electrical responses of the retinal cells to light, helping our retina specialists assess the function of the retina even if the split is not immediately visible on imaging.
To further evaluate the blood vessels in your retina, a dye is introduced into your bloodstream, and a specialized camera takes images of the retina. This test helps determine if the retinal circulation is affected, which can be important in assessing overall retinal health.
The retina, which is normally a single, cohesive layer, splits into two distinct layers. This separation mostly affects the peripheral areas of the retina but can sometimes extend closer to the center, affecting vision depending on the extent of the split.
In many cases, degenerative retinoschisis is benign and does not have an immediate impact on central vision. However, it is important to attend regular check-ups since progression to complications like retinal holes or detachment is possible, particularly with the bullous type.
While it often remains stable and asymptomatic, in rare cases where complications develop, vision loss can occur. That’s why routine monitoring and early intervention, if necessary, are key components of managing the condition.
Tests such as ophthalmoscopy, OCT, B-scan ultrasonography, ERG, and angiography are commonly used to assess your retina. These imaging and diagnostic tools help clarify the situation and inform the treatment plan, ensuring that any changes are caught early.
