Panretinal Photocoagulation (PRP) Laser is a specialized laser treatment used to manage and stabilize retinal diseases, primarily proliferative diabetic retinopathy. It works by applying laser burns to the peripheral retina to prevent the growth of abnormal blood vessels. This treatment plays a crucial role in protecting vision by reducing the risk of severe complications related to retinal ischemia.
Here’s the thing: the health of the retina is vital for clear and steady vision. When abnormal blood vessels start developing at the back of the eye, especially in patients with diabetic retinopathy or retinal vein occlusion, action is needed quickly to prevent further vision loss. Panretinal Photocoagulation Laser is designed to address these issues by strategically targeting and treating areas that are lacking proper blood flow.
This treatment is not designed to improve existing vision. Instead, it aims to halt the progression of abnormal vessel growth, which helps reduce the risk of vitreous hemorrhage, retinal detachment, or painful increases in eye pressure. Our Retina Specialists employ advanced laser technology to carry out this procedure with care and precision.
Panretinal Photocoagulation Laser (PRP) is a laser-based treatment for retinal diseases marked by the formation of abnormal blood vessels. In conditions like proliferative diabetic retinopathy, tiny yet fragile blood vessels start growing on the surface of the retina. These vessels can leak, bleed, or cause a build-up of fluid that threatens overall vision.
The treatment involves delivering multiple small laser burns to the peripheral regions of the retina. These burns intentionally scar areas with significant ischemia (lack of oxygen) to reduce the retina’s demand for oxygen. This process helps in shutting down the stimulus for new, abnormal vessels to develop.
Let me explain how the PRP Laser works. A laser, which may emit green, yellow, or red light, is carefully applied to the retina using special instruments like a slit lamp or a Laser Indirect Ophthalmoscope (LIO). The light energy burns the targeted retinal tissue in a controlled manner, leading to scarring. This scarring helps to stop the production or further progression of fragile, abnormal blood vessels.
By creating these deliberate burns, the retina’s overall need for oxygen decreases. Consequently, the body's natural healing response is triggered, which further helps to shrink the abnormal blood vessels. It’s a preventive approach meant to stop further deterioration of vision rather than to restore vision that has already been compromised.
Abnormal or new blood vessels develop when parts of the retina do not receive adequate oxygen—a condition known as ischemia. The retina, in its effort to counteract the oxygen deficiency, produces these fragile vessels. Unfortunately, while well-intentioned, these vessels are prone to leaking and rupturing, which can worsen retinal damage.
Panretinal Photocoagulation works by burning segments of the ischemic retina. This controlled injury reduces the retina’s stimulus for new vessel formation. The scarring that results essentially 'decommissions' the problematic region, preventing further vessel growth that can lead to complications like bleeding into the vitreous or even retinal detachment.
Preparation is key when it comes to experiencing a smooth and confident treatment session. Before undergoing PRP Laser, patients are encouraged to read the detailed information leaflet provided by the clinic. Sharing this information with a partner or family member can be very helpful, especially if extra support is needed during and after treatment.
There are a few important things to keep in mind:
Your comfort and understanding of the process are a priority. It is always a good idea to ask questions in the clinic if anything about the procedure seems unclear.
On the day of your treatment, you will be required to check in at the Eye Hospital Reception or the Day Case Unit. Once there, a nurse will welcome you and check your vision before administering dilating drops to your treated eye. These drops help the treating Retina Specialists to have an unobstructed view of the back of your eye for precise treatment.
During the procedure, you may be asked to sign a consent form after having any specific risks and expectations of the procedure explained to you in detail. It’s worth noting that the procedure is usually carried out over one or more treatment sessions, depending on the extent of retinal disease and your tolerance for the procedure.
The actual laser treatment involves the following steps:
Throughout the session, you might feel a sense of warmth or notice a dull ache in the treated eye. This sensation is common and often managed with over-the-counter pain relief medication, similar to what you’d use for a headache.
Immediately following the PRP Laser treatment, you’ll notice some temporary changes in your vision. The eye that received the treatment may appear “dazzled” or somewhat darker due to the laser burns and the lingering effect of the dilating drops. This altered vision typically resolves within 24 to 48 hours.
It’s important to remember that while you may experience a degree of discomfort or vision changes, these effects are expected and usually temporary. To ensure your comfort, our Retina Specialists might suggest taking pain relief medication, such as paracetamol, which is effective in managing any mild discomfort or dull ache post-treatment.
Due to the temporary visual impairments, you should avoid driving for at least 24 hours after the procedure. A follow-up appointment will be scheduled to assess how your eye is responding to the treatment, and to determine if further sessions are required. This follow-up is an essential aspect of ensuring the treatment’s effectiveness and maintaining your overall retinal health.
While the initial treatment plan may require multiple sessions, it's important to note that PRP can be repeated or combined with other therapies if the disease continues to progress. This flexible approach allows for adjustments to the treatment strategy, ensuring that patients receive comprehensive care tailored to the evolving needs of their retinal health.
Vascular endothelial growth factor (VEGF) is a key molecule that stimulates the formation of abnormal and fragile blood vessels in response to retinal ischemia. Elevated levels of VEGF are commonly found in proliferative diabetic retinopathy and other retinal conditions.
Panretinal Photocoagulation (PRP) creates controlled burns in the peripheral retina, reducing its oxygen demand. This decrease in metabolic stress leads to lower VEGF production, indirectly preventing the formation of abnormal vessels.
In modern treatment protocols, PRP is sometimes combined with intravitreal anti-VEGF injections. This combination addresses both the structural issues in the retina and the molecular pathways that drive abnormal vessel growth.
By using both PRP and anti-VEGF injections, the treatment strategy can be optimized to stabilize the retina and improve overall outcomes for patients with diabetic retinopathy. This dual approach targets the root causes of vessel proliferation while providing a comprehensive management plan.
Although very uncommon, watch for symptoms like sudden flashes of light, an increase in floaters, or a curtain-like shadow over your vision. If these occur, contact our office immediately so we can provide prompt care.
Reducing Bleeding Risk: By inducing controlled scarring of the abnormal vessels, the laser treatment minimizes the chance of bleeding into the vitreous, the gel-like substance inside the eye.
Protecting the Drainage System: The treatment decreases the likelihood that new, abnormal vessels will invade the eye’s drainage channels, which can lead to increased internal eye pressure and painful glaucoma.
Metabolic Demand Reduction: Scarring from the laser lowers the metabolic needs of the retina, discouraging the growth of additional abnormal vessels that could worsen retinal damage.
The laser creates small, precise scars in the peripheral retina, reducing its oxygen demand and signaling the body to halt abnormal vessel growth. This method carefully treats the affected areas while preserving central vision.

Not every patient with retinal disease requires PRP Laser treatment. Eligibility is based on the severity of abnormal vessel growth and overall eye health. PRP is typically reserved for advanced proliferative diabetic retinopathy or, in some cases, ischemic retinal vein occlusion, and may not be indicated in early stages of diabetic retinopathy.
Timely evaluation is crucial to maximize the benefits and minimize risks. Early intervention ensures that the treatment is introduced at a stage where it can provide the best possible outcome for patients with advanced retinal disease.
Certain media opacities, such as dense cataracts, may necessitate alternative imaging or treatment approaches. Addressing these issues early helps set proper expectations and ensures that the chosen treatment strategy is tailored to the patient’s specific condition.
Our Retina Specialists employ advanced imaging technologies—such as optical coherence tomography (OCT) and fluorescein angiography—to obtain a detailed picture of your retina before, during, and after treatment.
This detailed assessment is essential for tailoring the PRP Laser procedure to your specific condition. By pinpointing areas of retinal ischemia, our specialists can apply the laser burns with exceptional precision, ensuring that only the necessary areas are treated while preserving as much healthy tissue as possible.
In every step of the process—from the initial consultation and preparation to the actual treatment and follow-up—our Retina Specialists are committed to providing personalized, compassionate care. If you ever have any questions or concerns about the treatment, please don’t hesitate to call our office. We’re here to help clarify your options and to support you through each stage of your eye care journey.
No, the primary purpose of PRP Laser treatment is to halt the progression of abnormal blood vessel growth. The goal is to prevent further vision loss rather than to restore lost vision.
While the treatment is not completely painless, most patients experience only a dull ache or discomfort. Local anesthesia is used to help manage any discomfort during the procedure.
The number of sessions depends on the extent of your retinal disease and your individual tolerance. In many cases, the treatment may be divided into two or three sessions to achieve the best results without overwhelming the eye.
Some patients may experience a decrease in peripheral vision, temporary changes in night vision, or altered contrast sensitivity. These side effects are weighed against the benefits of preventing more serious complications.
Due to blurred vision from the dilating drops, it’s important to avoid driving for at least 24 hours after the treatment. Most other activities can be resumed once your vision begins to clear.
If you have more questions about the treatment process or post-treatment expectations, our Retina Specialists are always available to provide tailored guidance based on your specific condition.
Follow-up care is critical to ensure that the effects of the Panretinal Photocoagulation Laser remain stable and continue to protect your vision. Follow-up appointments give our Retina Specialists the opportunity to assess the treated areas, evaluate the healing process, and determine if additional sessions are needed.
The retina is carefully examined for any changes in the appearance of abnormal vessels or signs of further ischemia. In some cases, adjustments to the treatment plan may be made based on how your eye is responding. This ongoing care is a cornerstone of effective retinal management and is tailored to your specific needs.
These are important not only for ensuring the immediate success of the treatment but also for long-term visual stability. Our Retina Specialists emphasize patient education, and you’ll be informed about what signs to watch for and when to seek additional medical advice. This collaborative approach helps in maintaining your eyes’ health over the years.
It’s normal to feel a bit uneasy when you notice changes in your vision right after undergoing PRP Laser treatment. However, most of these changes—such as temporary blurred vision, decreased contrast sensitivity, or mild discomfort—are expected outcomes.
