Panretinal Laser Photocoagulation
Pain with severe changes in the eye's blood vessels is not always present. Therefore, the patient may believe the condition is stable, although the retina is already deprived of oxygen and responds by growing weak new vessels. Panretinal laser photocoagulation is used in such conditions. This procedure is necessary to reduce vascular activity and reduce the risk of vision complications.

What is panretinal laser photocoagulation and when is it needed?
This method involves the doctor applying controlled laser pulses to the periphery of the fundus. The laser targets ischemic areas rather than the center responsible for clear vision. This reduces vascular activity and the risk of hemorrhage.
Prolonged oxygen deprivation leads to retinal neovascularization. These vessels bleed easily and can lead to scarring.
How does panretinal photocoagulation work?
Panretinal photocoagulation is based on the precise thermal action of a laser. The doctor treats the peripheral areas where the retina suffers most from a lack of blood supply and supports the growth of new vessels. After treatment, the vascular stimulus is reduced.
The main goal is to stabilize the process and reduce the risk of further vision deterioration.
For what conditions do we recommend the procedure?
Retinal laser coagulation is most often used for complications of diabetes. The doctor assesses the stage of the disease, the macula, the periphery, and the transparency of the optical media. Based on the examination results, the treatment volume is determined.
The procedure is considered for the following conditions:
- Proliferative diabetic retinopathy
- Severe retinal neovascularization
- High risk of hemorrhage
- Need to prevent complications
This list does not replace a consultation. The decision is made by an ophthalmologist after an in-person evaluation.
Indications and limitations for treatment
Indications depend on the diagnosis and the activity of the process. The ocular condition of two diabetic patients can differ significantly. Therefore, the doctor examines the fundus, studies the images, and assesses the safety of the procedure.
Panretinal laser photocoagulation is not performed formally. In cases of severe macular edema, dense hemorrhage, medial opacity, or other limitations, the doctor may first suggest another stage. The strategy should reduce risk.
Proliferative diabetic retinopathy and other retinal conditions
Diabetic retinopathy develops when diabetes mellitus damages the small retinal vessels. In the early stages, changes may occur without any noticeable symptoms.
As the disease progresses to a proliferative form, new, weak vessels begin to grow. Proliferative diabetic retinopathy is dangerous due to hemorrhages, scarring, and tractional retinal detachment.
When You Shouldn't Delay a Visit to the Ophthalmologist
Don't delay if your vision has suddenly deteriorated, you experience a "curtain" in front of your eye, flashes, pain, redness, or a sudden increase in floaters. These symptoms require an examination because they may be related to:
- Hemorrhage
- Retinal Tension
- Another Complication
With diabetes, regular vision monitoring is necessary, even if a person's vision is normal and nothing bothers them.
General information
How panretinal laser coagulation is performed at our clinic
At our clinic, diagnosis, laser treatment, and follow-up are all part of a single procedure. The doctor explains the purpose of the procedure, the possible sensations, and when to return for a follow-up appointment.
Before the procedure, an individual treatment plan is developed. It takes into account the diagnosis, the area of ischemia, the condition of the macula, and the patient's tolerance to the treatment. Sometimes the procedure is performed in a single visit, while other times it is divided into stages.
Preparation for the procedure
Preparation begins with an appointment. The ophthalmologist will review the diagnosis, any complaints, previous surgeries, eye injections, and any episodes of hemorrhage. Afterward, the doctor will examine the posterior segment of the eye and determine if laser treatment is safe.
To clearly see the periphery of the retina, the pupil must be dilated. After applying the drops, vision may remain blurred for several hours. On the day of the appointment, it's best not to drive and plan your return journey home in advance.
Key Stages of the Session
Local anesthetic drops are used beforehand. The doctor then inserts a contact lens or uses a magnifying system. Laser retinal treatment follows the protocol chosen after diagnosis.
What sensations occur during and after the laser treatment?
During the session, flashes of light and a feeling of pressure from the lens are possible. Moderate discomfort or short painful pulses are possible. After the procedure, vision may be blurred. Light sensitivity or aching pain may sometimes occur. In such situations, the doctor will explain in advance when an urgent call to the clinic is needed.
Frequently Asked Questions
Patients often ask similar questions before treatment. The doctor provides personalized recommendations only after an examination.
What is PRC and why is this procedure necessary?
Is PRC painful?
How long does recovery take after the procedure?
Can vision be fully restored after panretinal coagulation?
Our clinic offers retinal treatment, including diagnostics, laser treatment, and follow-up. If your vision has worsened due to diabetes, you've experienced floaters or flashes, or your doctor has already mentioned the risk of vascular complications, don't delay your appointment. An ophthalmologist will examine your fundus, conduct a physical examination, and explain whether laser retinal treatment is appropriate.
Doctor's quote:
"Our goal is not just to perform laser treatment, but to accurately determine the scope of treatment and preserve the maximum possible functional potential of the retina. Therefore, we always begin with a thorough diagnosis and provide patient support after the procedure."
You can schedule an appointment in advance to choose a convenient time. During the consultation, the doctor will assess your eye condition, explain the plan, and provide recommendations. If panretinal laser photocoagulation is needed, it's best to make the decision after a comprehensive diagnosis.
