What Is Retinal Detachment?
Retinal detachment is a medical emergency in which the retina — the thin layer of light-sensitive tissue lining the back of the eye — separates from its underlying supportive tissue. When the retina detaches, it loses access to its blood supply and the oxygen and nutrients it needs to function. Without prompt surgical intervention, retinal detachment can cause permanent vision loss in the affected eye.
Retinal detachment requires urgent evaluation, ideally within 24 hours of symptom onset. If you experience a sudden increase in floaters, flashes of light, or a shadow spreading across your vision, contact West Boca Eye Center immediately. Early treatment significantly improves the likelihood of preserving and restoring vision.
Types of Retinal Detachment
There are three types of retinal detachment, each with a different underlying cause and treatment approach:
Rhegmatogenous Retinal Detachment
The most common type. A tear or break in the retina allows vitreous fluid to seep behind the retina and separate it from the underlying tissue. Rhegmatogenous detachments are most often caused by age-related changes in the vitreous gel, which shrinks and pulls away from the retina over time. If the vitreous pulls hard enough to create a tear, fluid passes through the opening and lifts the retina from the eye wall.
Tractional Retinal Detachment
Scar tissue on the retina contracts and pulls the retina away from the back of the eye. This type is most commonly associated with diabetic retinopathy, where abnormal blood vessel growth leads to scar formation on the retinal surface. Patients with poorly controlled diabetes are at elevated risk.
Exudative Retinal Detachment
Fluid accumulates beneath the retina without a tear or break being present. This type can result from inflammatory disorders, vascular abnormalities, or tumors behind the retina. Treatment focuses on the underlying condition causing fluid buildup rather than surgical reattachment of the retina itself.
Symptoms and Warning Signs
Retinal detachment is painless, which is why recognizing the visual warning signs is critical. Symptoms typically develop suddenly and may include:
- A sudden increase in floaters — dark spots, specks, or cobweb-like shapes drifting across your vision
- Sudden flashes of light in the affected eye, especially in peripheral vision
- A shadow or dark curtain spreading across part of your visual field
- Blurred or distorted vision that worsens progressively
- A sensation of heaviness in the eye
These symptoms can develop over hours or days. A few occasional floaters are common and usually harmless, but a sudden shower of new floaters — especially accompanied by flashes of light — warrants immediate evaluation. Dr. Brent Bellotte and the retina team at West Boca Eye Center provide urgent consultations for patients experiencing these symptoms.
How Is Retinal Detachment Diagnosed?
At West Boca Eye Center, Dr. Bellotte uses several diagnostic tools to evaluate the retina and determine the type, location, and extent of detachment:
- Dilated eye examination: Drops are used to widen the pupil, allowing a thorough view of the retina through an ophthalmoscope. This is the first step in identifying tears, holes, or areas of detachment.
- Optical coherence tomography (OCT): A non-invasive imaging scan that produces high-resolution cross-sectional images of the retina. OCT can detect subtle fluid accumulation beneath the retina and measure retinal thickness with precision.
- Ultrasound imaging: If bleeding or other opacities prevent a clear view of the retina, an ultrasound probe is placed gently against the eyelid to create a real-time image of the retinal structures behind the obstruction.
- Fluorescein angiography: A fluorescent dye is injected into a vein in the arm and photographed as it circulates through the blood vessels of the retina. This test identifies areas of leakage, abnormal blood vessel growth, or compromised blood flow.
These diagnostic methods allow Dr. Bellotte to map the detachment precisely and determine the most appropriate surgical approach for each patient.
Retinal Detachment Treatment
All retinal detachments require treatment. The specific procedure depends on the type of detachment, its severity, and how much of the retina is affected. Dr. Bellotte performs the following retinal detachment surgeries at West Boca Eye Center in Boca Raton:
Pneumatic Retinopexy
A gas bubble is injected into the vitreous cavity of the eye, where it rises and presses against the detached retina, pushing it back into position against the eye wall. The retinal tear is then sealed with cryopexy (freezing treatment) or laser photocoagulation. Pneumatic retinopexy is typically used for smaller, uncomplicated detachments in the upper portion of the retina. After the procedure, specific head positioning is required to keep the gas bubble pressing against the correct area. The bubble is gradually absorbed by the body over one to three weeks.
Scleral Buckling
A silicone band or sponge is sutured to the outside of the eye (the sclera), creating an indentation that pushes the eye wall inward toward the detached retina. This relieves the traction pulling on the retina and allows it to reattach. The buckle remains permanently in place and is not visible. Scleral buckling is effective for detachments caused by multiple tears or when the detachment is more extensive. It is often combined with cryopexy to seal the retinal tears.
Vitrectomy
The vitreous gel is surgically removed to eliminate any traction pulling on the retina. Dr. Bellotte then uses laser or cryopexy to seal the retinal tears and fills the eye with air, gas, or silicone oil to hold the retina in place during healing. Air and gas bubbles are naturally absorbed by the body and replaced by the eye's own fluid over several weeks. Silicone oil provides longer-term support but requires a second procedure for removal, typically three to six months later. Vitrectomy is the most versatile approach and is used for complex, large, or recurrent detachments.
Cryopexy and Laser Photocoagulation
Cryopexy (freezing) and laser photocoagulation (focused light energy) are used to seal retinal tears and prevent them from progressing to full detachment. These treatments create a controlled scar that bonds the retina to the underlying tissue. They can be performed as standalone procedures for retinal tears that have not yet progressed to detachment, or in combination with pneumatic retinopexy, scleral buckling, or vitrectomy.
What to Expect After Retinal Detachment Surgery
Recovery varies depending on the procedure performed and the extent of the detachment. General guidelines include:
- Head positioning: After pneumatic retinopexy or vitrectomy with gas, you may need to maintain a specific head position — often face-down — for several days to several weeks. This keeps the gas bubble pressing against the retina in the correct location. Dr. Bellotte will provide specific positioning instructions based on the location of your detachment.
- Activity restrictions: Avoid strenuous activity, heavy lifting, and bending at the waist for the first two to four weeks. These activities can increase pressure inside the eye and interfere with healing.
- Air travel restriction: If a gas bubble was placed in your eye, you cannot fly or travel to high altitudes until the bubble has fully absorbed. Changes in air pressure can cause the gas to expand, dangerously increasing eye pressure.
- Vision recovery timeline: Some improvement may be noticeable within a few weeks, but full visual recovery typically takes three to six months. The final level of vision depends on how long the retina was detached and whether the macula (central retina) was involved.
- Follow-up appointments: Frequent follow-up visits are scheduled in the weeks after surgery to monitor healing, check eye pressure, and confirm the retina remains attached.
Retinal reattachment surgery is successful in approximately 90 percent of cases with a single procedure. In some cases, a second surgery may be needed to fully reattach the retina. Even after successful reattachment, some patients experience changes in vision depending on the duration and extent of the original detachment — particularly if the macula was involved.
Risk Factors
Certain factors increase the likelihood of developing retinal detachment:
- Age — most common in adults over 50, with risk increasing after age 60
- Severe nearsightedness (high myopia) — elongated eyes have thinner retinas
- Previous cataract surgery or other intraocular procedures
- Family history of retinal detachment
- Previous retinal detachment in either eye
- History of eye trauma or injury
- Diabetic retinopathy or other retinal diseases
- Areas of retinal thinning (lattice degeneration)
If you have one or more of these risk factors, regular dilated eye exams are essential for early detection of retinal tears or thinning before they progress to detachment.
Prevention
While not all retinal detachments can be prevented, you can reduce your risk by:
- Scheduling annual dilated eye exams, especially if you are over 50, highly nearsighted, or have a family history of retinal detachment
- Wearing protective eyewear during sports, yard work, and any activity that poses a risk of eye injury
- Seeking immediate evaluation for any sudden increase in floaters, flashes of light, or changes in peripheral vision
- Managing systemic conditions such as diabetes that can affect retinal health
- Discussing your risk factors with your ophthalmologist so that early warning signs can be monitored
Retinal tears, if detected before they progress to detachment, can often be treated with laser or cryopexy in the office — a significantly simpler procedure than full detachment surgery.

Frequently Asked Questions
Is retinal detachment a medical emergency?
Yes. Retinal detachment requires urgent treatment, ideally within 24 hours of symptom onset. The retina cannot function without its blood supply, and the longer it remains detached, the greater the risk of permanent vision loss. If the macula detaches, central vision may be permanently affected even after successful surgery. Seek evaluation immediately if you experience a sudden shower of floaters, flashes of light, or a shadow spreading across your vision.
What types of surgery are used to repair a detached retina?
The three primary surgical approaches are pneumatic retinopexy (a gas bubble injection to push the retina back into place), scleral buckling (a silicone band placed on the outside of the eye), and vitrectomy (removal of the vitreous gel with gas or oil tamponade). The procedure Dr. Bellotte recommends depends on the type, size, and location of the detachment. Cryopexy and laser are used alongside these procedures to seal retinal tears.
How long does it take to recover from retinal detachment surgery?
Initial healing takes two to four weeks, during which activity restrictions and head positioning requirements apply. Noticeable vision improvement often begins within the first few weeks, but full visual recovery typically takes three to six months. Patients who had gas bubble placement cannot fly until the bubble absorbs completely, which may take one to three weeks depending on the type of gas used.
What is the success rate for retinal detachment surgery?
Retinal reattachment surgery is successful in approximately 90 percent of cases with a single procedure. Some complex or recurrent detachments may require a second surgery. The degree of vision recovery depends on how long the retina was detached and whether the macula was involved prior to surgery. Earlier treatment generally leads to better visual outcomes.
Can retinal detachment happen again after surgery?
Yes, recurrence is possible. Patients who have had retinal detachment in one eye are at higher risk for detachment in the other eye as well. Regular follow-up examinations after surgery are essential to monitor for new tears or re-detachment. Dr. Bellotte schedules frequent post-operative visits and provides guidance on warning signs to watch for during recovery and beyond.
