Laser Retinopexy: Sealing Retinal Tears to Protect Your Vision
Who Is at Risk for Retinal Tears?
Retinal tears can occur in anyone, but certain factors make them significantly more likely. Understanding your personal risk helps guide how often you should be monitored and when to seek urgent care.
The most common cause of a retinal tear is a posterior vitreous detachment (PVD), a natural process in which the vitreous gel inside the eye shrinks and pulls away from the retina with age. This pulling force can tug on the retina and create a tear. PVD becomes increasingly common after age 50 and is responsible for the majority of acute retinal tears seen by Retina Specialists.
Several conditions increase the likelihood that a retinal tear will develop or require treatment. Your Retina Specialist will take these into account when planning your care.
- High myopia (severe nearsightedness), which significantly increases retinal tear risk compared to non-myopic individuals
- Lattice degeneration, a thinning and weakening pattern in the peripheral retina found in a small portion of the general population
- Prior cataract surgery, particularly when combined with lattice degeneration
- A previous posterior vitreous detachment
- Eye trauma or injury
- A personal or family history of retinal detachment
Even after a successful laser seal, some eyes require retreatment. A meaningful percentage of treated eyes need additional laser at a follow-up visit, with roughly half of those cases involving a new tear in a different location rather than the original one. Factors associated with a higher likelihood of needing further treatment include tears in the upper-outer region of the retina, the presence of bleeding inside the eye (vitreous hemorrhage), and having multiple retinal breaks at the time of initial treatment.
Symptoms to Watch For
Knowing the warning signs of a retinal tear is one of the most important things you can do to protect your vision. Some tears cause no symptoms at all, but many produce sudden, noticeable changes that call for immediate attention.
The following symptoms can appear suddenly and should never be ignored or dismissed as normal aging changes in your vision.
- A sudden increase in floaters, especially a shower of small dark spots, strings, or cobweb-like shapes
- Flashing lights (called photopsia), often seen as brief streaks or arcs in the side vision
- A shadow or curtain spreading across part of your visual field
- A sudden decrease in overall vision clarity
Any of these symptoms, especially in combination, warrant same-day evaluation by a Retina Specialist.
If you experience new floaters, flashing lights, or a shadow across your vision, do not wait for a routine appointment. These can be signs of an active retinal tear or early retinal detachment, and time is critical. A Retina Specialist needs to examine your eye the same day these symptoms begin.
It is also important to know that even if your initial exam after a PVD appears normal, there remains a real risk of developing new retinal breaks in the weeks that follow. This is one reason why follow-up exams are scheduled even when nothing is found on the first visit.
How a Retinal Tear Is Diagnosed
Diagnosing a retinal tear requires a thorough examination by a Retina Specialist. Because tears most often occur in the far edges of the retina, a standard eye exam is not sufficient, and specialized techniques are needed to see the full picture.
Dilating drops are placed in the eye to widen the pupil, allowing the Retina Specialist to see the entire retina, including its outermost edges. Using a specialized lens and bright light source, the specialist carefully examines the peripheral retina for tears, holes, and areas of thinning such as lattice degeneration. This examination is the primary tool for detecting retinal breaks.
Additional imaging may be used to confirm the diagnosis or plan treatment. Optical coherence tomography (OCT) is a non-invasive scan that produces detailed cross-sectional images of the retina and can reveal fluid beneath the retina or subtle structural changes near a tear. Wide-field retinal photography captures detailed images of the peripheral retina and provides a documented baseline for comparison at future visits. Our team also uses OCT angiography, fluorescein angiography, and B-scan ultrasound when additional information is needed.
Treatment Options for Retinal Tears
The goal of treatment is to create a stable seal around the tear before fluid can pass beneath the retina and cause a detachment. The right approach depends on the size, location, and characteristics of the tear.
Laser retinopexy is the preferred treatment for most retinal tears. Our Retina Specialists generally favor it over other options because it produces faster tissue adhesion and carries a lower risk of complications. Treatment typically involves applying two or more near-confluent rows of laser burns that fully surround the tear, creating a complete barrier.
Some tears are positioned far forward in the eye or in locations that are difficult to reach with a laser beam. In these cases, cryopexy may be used instead. Cryopexy is a freezing treatment applied to the outside of the eye that achieves the same goal of producing scar tissue to seal the tear. The choice between laser and cryopexy depends on where the tear is located and which approach allows for the most complete seal.
In select cases where a retinal detachment has already begun, a Retina Specialist may use pneumatic retinopexy alongside laser treatment. Pneumatic retinopexy involves injecting a small gas bubble into the eye to gently push the detached retina back against the wall of the eye. Once the retina is repositioned, laser retinopexy is performed to seal the tear. The gas bubble dissolves on its own over the following weeks.
For certain patients at very high risk of retinal detachment, such as those with Stickler syndrome, a genetic connective tissue disorder, a Retina Specialist may recommend treating vulnerable areas of the peripheral retina even before a tear develops. This preventive approach has been shown to meaningfully reduce detachment risk in appropriate candidates. Your specialist will discuss whether preventive treatment is right for your individual situation.
What to Expect Before, During, and After Treatment
Laser retinopexy is performed right in our office and takes less than 30 minutes from start to finish. Knowing what to expect helps you feel prepared and confident going into the procedure.
No special preparation is typically required before laser retinopexy. Dilating drops are placed in the eye to widen the pupil, and a topical anesthetic drop numbs the surface of the eye. A special contact lens may be placed gently on the eye to help focus the laser beam precisely onto the retina.
You will be seated at the laser instrument, which looks similar to the equipment used in a routine eye exam. You will see bright flashes of light with each laser pulse. Some patients notice a mild stinging or dull aching sensation during treatment, particularly when treating larger tears. Most patients find the experience very manageable, and the active treatment portion lasts only a few minutes.
Your vision may be slightly blurry for several hours after the procedure due to the dilating drops and the intensity of the laser light. Mild discomfort or a dull ache around the eye for a few hours is normal, and over-the-counter pain relievers are usually all that is needed. Most patients return to their normal daily activities the same day or the following day.
Your Retina Specialist will schedule a follow-up visit within one to two weeks to confirm the laser seal is forming properly. During this healing period, it is important to avoid heavy lifting and strenuous physical activity, as your specialist instructs.
Laser retinopexy is considered very safe, but as with any procedure, risks exist. Possible complications include inadvertent burns to nearby retinal structures, mild inflammation inside the eye, and small changes in peripheral vision near the treated area. In a small number of cases, the seal may not hold and the tear can progress to a retinal detachment, requiring more extensive surgery such as vitrectomy (removal of the gel inside the eye) or scleral buckle (a silicone band placed around the outside of the eye to support the retinal repair).
Long-Term Care After Laser Retinopexy
Treating the tear is an important first step, but protecting your vision long-term requires ongoing attention. Continued monitoring and awareness of new symptoms are essential parts of your care after laser retinopexy.
Your Retina Specialist will determine the right follow-up schedule based on your individual risk factors. Patients with high myopia, lattice degeneration, or a history of tears or detachment in the other eye may benefit from more frequent monitoring visits. Retinal photography at each visit allows our team to compare images over time and detect any subtle changes early.
Between appointments, paying close attention to your vision is one of the most valuable habits you can develop. Some specialists recommend checking each eye separately on a regular basis by covering one eye at a time and noting any changes. New floaters, flashing lights, or a shadow across any part of your vision should prompt you to contact your Retina Specialist right away, without waiting for your next scheduled visit.
When a retinal tear is caught early and the laser seal forms successfully, the long-term outlook is generally very favorable. Most patients retain the level of vision they had before the tear occurred. The treated area will show a small ring of pigmented scar tissue, but this typically does not affect daily vision. Attending all recommended follow-up visits and responding quickly to any new symptoms gives you the best opportunity to maintain good outcomes over time.
Frequently Asked Questions
Here are answers to questions our patients commonly ask about laser retinopexy, including guidance on recovery, recurrence, and when to seek urgent care.
The surface of the eye is numbed with anesthetic drops before treatment begins, so most patients experience only minor sensations. You may feel a brief sting or mild ache with each laser pulse, particularly if the tear is large or located near a sensitive area of the retina. This discomfort typically passes within a few hours. If any lingering soreness occurs afterward, over-the-counter pain relievers are usually sufficient.
Reading, watching television, and light daily tasks are generally fine to resume the same day or the next day. However, your Retina Specialist will typically advise you to avoid heavy lifting and vigorous exercise for one to two weeks while the scar tissue finishes forming. Following these restrictions carefully gives the laser seal the best chance of becoming fully stable before physical strain is placed on the eye.
The original sealed tear generally remains stable once the scar tissue matures. However, new tears can develop in entirely different areas of the retina, particularly in patients with ongoing risk factors such as high myopia or lattice degeneration. This is why regular follow-up exams remain important even after a successful treatment. Your Retina Specialist will recommend a monitoring schedule that is appropriate for your level of risk.
In a small number of cases, fluid may still pass through the tear despite laser treatment, leading to a partial or full retinal detachment. If this occurs, more involved surgical procedures such as vitrectomy or scleral buckle surgery would be necessary. Attending your follow-up appointments as scheduled allows your Retina Specialist to detect any failure of the seal early, before a larger detachment develops and while treatment options remain straightforward.
These two procedures are entirely different and should not be confused. LASIK is a refractive surgery that reshapes the cornea, the clear front surface of the eye, to reduce the need for glasses or contacts. Laser retinopexy uses a different type of laser directed at the retina at the back of the eye to seal a tear and prevent detachment. They treat different structures, different conditions, and have nothing in common beyond the word laser.
Any sudden onset of new floaters, flashing lights, or a shadow or curtain across any part of your vision should be treated as urgent, not something to observe overnight. These symptoms can signal an actively progressing tear or early detachment, and waiting even a day can allow fluid to spread beneath the retina and complicate treatment. If you cannot reach your Retina Specialist immediately, go to the nearest emergency room and explain that you may have a retinal tear.
