The Foldable Capsular Vitreous Body (FCVB) is a medical device made to replace the natural gel (the vitreous) inside the back part of the eye when that gel is lost, damaged, or when the eye is badly injured. It is a soft, thin capsule shaped like the normal vitreous body. Surgeons fold it, place it inside the eyeball, and then fill it through a valve system with a fluid such as silicone oil or balanced salt solution. Once filled, it pushes gently outward to support the retina and keeps the shape of the eyeball. It is used especially in very difficult eye cases where other treatments have failed or where the eye is in danger of shrinking or becoming nonfunctional. PubMedPMCPMCEyeWikiBioMed CentralIOVS
The Foldable Capsular Vitreous Body is a medical implant designed to replace or support the natural vitreous gel inside the eye when that gel has been lost or severely damaged, such as after major trauma, complicated retinal detachment, or in eyes dependent on silicone oil. It is a soft, foldable capsule made from specially modified liquid silicone rubber that can be implanted into the vitreous cavity and then filled—most commonly with silicone oil—to act as an internal tamponade. This device holds the retina in place, helps maintain intraocular pressure, and minimizes direct contact between the tamponading fluid (like silicone oil) and delicate ocular tissues, reducing emulsification and inflammation. Early and mid-term studies report that FCVB can remain in the eye for extended periods with relatively low complication rates and can achieve retinal reattachment in many challenging cases. ResearchGate Lippincott Journals TVST
The FCVB acts like an internal scaffold or internal balloon that holds the retina in place, prevents the eye from collapsing, and avoids some problems that happen with direct use of silicone oil (like the oil moving around or causing damage). It can also be used as a vehicle to slowly release drugs inside the eye. FrontiersTVST
Types and Variations of FCVB
Although the general design of FCVB is consistent— a foldable capsule with a tube-valve system— there are meaningful variations and developments. Below are the major types or functional variations:
Silicone Elastomer Capsule Filled with Silicone Oil: This is the original and most common version. The capsule is made of high-purity medical-grade silicone rubber. After implantation, it is filled with silicone oil through the valve to provide long-term internal pressure and retinal support. This design minimizes silicone oil emulsification and displacement compared to direct oil filling. IOVSMacquarie University
Silicone Rubber Capsule with Balanced Salt Solution (BSS): In some experimental or modified uses, the FCVB is filled with BSS to maintain intraocular volume without direct silicone oil contact, useful in selected scenarios to reduce some oil-related effects while still preserving eye shape. Frontiers
Drug-Eluting FCVB: The capsule can be loaded or combined with therapeutic drugs (for example, antibiotics like levofloxacin or anti-inflammatory agents like dexamethasone) for slow controlled release inside the eye. This dual function supports mechanical structure and local drug delivery. TVST
Pressure-Control Valve FCVB: Some versions include refinements aimed at regulating internal pressure, helping maintain a safer and more stable intraocular pressure over time. EyeWiki
Modified FCVB for Scleral Buckling: A novel adaptation uses a foldable capsular structure as part of a scleral buckle system to treat complex rhegmatogenous retinal detachment, especially where traditional buckling or vitrectomy alone is insufficient. Europe PMC
FCVB for Silicone Oil–Dependent Eyes: Eyes that cannot maintain retinal reattachment without silicone oil repeatedly require support; FCVB provides an intermediate solution between long-term oil tamponade and enucleation (removal), preserving the globe more stably. BioMed Central
Combination Designs in Clinical Trials: Various studies have trialed FCVBs with different fill substances, structural reinforcements, and postoperative positioning options, adjusting the inner content and stiffness to match patient needs. FrontiersIOVS
Each type maintains the core idea: a foldable capsule that provides internal support while reducing complications of free-floating vitreous substitutes. Macquarie University
Causes / Clinical Situations
The FCVB is not used for a single disease; it is chosen when the eye has suffered severe injury or disease that disrupts the normal vitreous-retinal interface, threatens the shape of the eye, or leaves prior treatments insufficient. Here are 20 distinct causes or clinical situations where FCVB is considered:
Severe Ocular Trauma (Globe Rupture or Penetrating Injury) – When the eyeball is torn or broken, internal structures are damaged; after reconstruction, FCVB can help keep the eye’s shape and prevent collapse. PubMedPMCResearchGate
Complicated Retinal Detachment – Detachments that are large, recurrent, or associated with scar tissue (e.g., rhegmatogenous with significant breaks) often need strong internal support. PMCBioMed Central
Proliferative Vitreoretinopathy (PVR) – Scar tissue forms on the retina causing traction and redetachment; conventional methods may fail, and FCVB provides a more stable long-term tamponade. PubMedMacquarie University
Silicone Oil–Dependent Eyes – Eyes that previously required long-term silicone oil but suffer from complications when oil is removed; FCVB acts as a safer alternative to continual free oil. BioMed Central
Recurrent Retinal Detachment after Silicone Oil Removal – When retina keeps detaching after oil is removed, FCVB can serve as a more secure internal support. BioMed Central
Eyes at Risk of Phthisis Bulbi (Eye Shrinking / Atrophy) – Severe injury or chronic detachment threatens the eye shrinking; FCVB helps maintain the globe’s structure to avoid this outcome. PMCResearchGate
Severe Vitreous Hemorrhage with Underlying Traction – When blood and scar tissue block vision and pull on the retina, FCVB helps after clearing and reattaching the retina. MDPI
Endophthalmitis Leading to Structural Damage – Deep infection inside the eye may damage internal support; after infection control, FCVB may be used to preserve the eye and reestablish internal volume. PMCBioMed Central
Ocular Atrophy from Chronic Disease – When chronic disease slowly deforms internal structures, FCVB can act to stabilize remaining anatomy. PMC
Traumatic Retinal Detachment with Stiff (Fibrotic) Retina – Trauma causing both detachment and stiffening makes reattachment difficult; FCVB provides consistent support while the retina heals.
Failed Vitrectomy with Persistent Non-attachment – When standard vitrectomy fails to keep the retina attached, FCVB is used as a salvage method. IOVS
Severe Ocular Inflammation with Structural Compromise – Inflammation (e.g., chronic posterior uveitis) that leads to vitreous changes or traction may necessitate replacement and structural support. MDPI
Tumor Involving the Vitreous/Posterior Segment (after excision) – After removing tumors that disrupt the vitreous-retinal interface, FCVB can help maintain anatomy. (Inference based on typical need for vitreous support after extensive posterior segment surgery.) MDPI
High-risk Retinal Surgery with Poor Prognosis for Reattachment – Eyes where conventional support is unlikely to succeed due to complexity may get FCVB earlier as a long-term support. Macquarie University
Complicated Diabetic Tractional Retinal Detachment – In advanced diabetic disease, fibrous membranes pull on the retina, and after removal, FCVB can stabilize both the retina and eye shape. MDPI
Combination Vitreoretinal Conditions (e.g., mixed PVR and traction) – Multiple overlapping mechanisms make standard tamponades insufficient; FCVB’s mechanical reliability helps. Macquarie University
Eyes with Uncontrolled Silicone Oil Emulsification – When silicone oil breaks into small droplets causing secondary issues, encapsulating the oil inside FCVB limits emulsification. Macquarie University
Severe Posterior Segment Scarring after Infection or Surgery – Scarring that distorts the globe internally may be better managed with an internal balloon-like support. BioMed Central
Prevention of Globe Collapse During Staged Surgeries – In multi-stage reconstruction, FCVB can temporize internal support while planning further correction. PMC
Eyes Refusing or Unsuitable for Enucleation/Artificial Eye – When patients wish to keep the natural globe despite low vision, FCVB can delay or avoid removal by maintaining form and preventing atrophy. BioMed Central
Symptoms
These symptoms are usually from the underlying diseases or injuries that eventually make a surgeon consider FCVB:
Sudden Severe Vision Loss – A major red flag, common in retinal detachment or trauma. MDPI
Curtain or Shadow Over Vision – Patients often describe a dark curtain coming across their field when the retina detaches. MDPI
Floaters and Flashes of Light – Early signs of vitreous traction or retinal tear that can progress to detachment. MDPI
Persistent or Recurrent Red Eye / Inflammation – Chronic inflammation may damage internal structures requiring structural support. MDPI
Eye Pain or Discomfort – Especially after trauma, infection, or increased internal tension. PubMed
Decreased Intraocular Pressure (Hypotony) – Can signal globe structural failure, leakage, or atrophy risk. FCVB helps stabilize pressure. PMCResearchGate
Enlarged or Misshapen Eye After Trauma – Structural damage or swelling signaling internal compromise. ResearchGate
Shrinking Eye (Early Phthisis Signs) – Warning that the globe is collapsing; FCVB can be used to prevent progression. PMC
Recurrent Retinal Detachment Symptoms after Prior Surgery – Symptoms like shadows returning after earlier repair. BioMed Central
Blurry Vision Not Improved with Glasses – Could be from internal changes like scar traction or detachment. MDPI
Distorted Vision (Metamorphopsia) – Retinal surface irregularity or traction; underlying detachments can cause this. MDPI
Visible Blood in the Eye (Hyphema or Vitreous Hemorrhage) – Indicates trauma or proliferative disease affecting internal structures. ResearchGate
Leakage or Wound Issues after Surgery (e.g., Seidel positive) – Structural breach may complicate healing and necessitate more stable internal support. IOVS
Poor Response to Prior Tamponade (e.g., silicone oil) with Recurrence – Signals need for alternate support method like FCVB. BioMed Central
Signs of Infection Inside Eye (Redness, Cloudy Media, Discharge) – Severe infection can damage vitreous-retinal interfaces and later require replacement. PMCBioMed Central
Diagnostic Tests
To decide whether FCVB is needed and to understand the underlying condition, doctors perform a range of exams and tests. These are grouped and explained below.
A. Physical Exam
Visual Acuity Measurement
This is the basic test of how well a person sees with each eye. It helps track loss of central vision from detachment, trauma, or other damage. MDPIPupillary Light Reflex Test
Shining light into the eye checks the pupil’s response. Abnormal reaction can signal optic nerve or severe retinal damage. MDPIExtraocular Muscle Movement (Motility)
The doctor asks the patient to follow a target to see if the eye moves normally. Restrictions may occur with trauma, inflammation, or internal pressure changes. ResearchGateExternal Eye Inspection
Looking at the eyelids, conjunctiva, cornea, and sclera for redness, swelling, scars, or deformity gives clues to trauma, infection, or chronic disease. ResearchGateIntraocular Pressure Measurement (Tonometry)
Measures pressure inside the eye. Too low may mean leakage or rupture; too high could complicate healing. FCVB helps stabilize pressure in fragile eyes. PMCIOVS
B. Manual Ophthalmic Tests
Slit-Lamp Examination
A focused light and microscope are used to inspect the front part of the eye (cornea, lens, anterior chamber) for inflammation, hemorrhage, or wound integrity. IOVSIndirect Ophthalmoscopy
This allows the doctor to see the back of the eye, including the retina and vitreous. It detects detachment, tears, scar tissue, or tumor involvement. BioMed CentralMDPISeidel Test
Used after surgery or trauma to check if fluid is leaking from the eye’s surface wound. A positive result means leakage and structural compromise. IOVSGonioscopy
Examination of the angle where fluid drains from the eye; helps rule out angle-related issues that might complicate pressure management. MDPIScleral Depression
Gently pressing on the outer white part of the eye during ophthalmoscopy improves visualization of peripheral retina and helps find small tears that could lead to detachment. MDPI
C. Laboratory and Pathological Tests
Vitreous or Aqueous Tap for Culture and Sensitivity
Sampling fluid from inside the eye helps find infection (bacterial/fungal) and guides appropriate antibiotic therapy before or after FCVB use. BioMed CentralPCR Testing for Infectious Agents
Polymerase chain reaction can detect viral or atypical pathogens (e.g., herpes viruses, tuberculosis) that cause internal inflammation or damage. BioMed CentralIntraocular Cytokine / Inflammatory Marker Analysis
Measuring levels of inflammatory signals (interleukins, etc.) can identify ongoing inflammation that may threaten surgical success or indicate underlying uveitis. MDPIBlood Tests for Systemic Disease
Tests like complete blood count, blood sugar (diabetes), and autoimmune panels (ANA, rheumatoid factor) help detect diseases that affect the retina or healing. MDPI
D. Electrodiagnostic Tests
Electroretinography (ERG)
Measures electrical responses of the retina to light. Helps assess retinal function when media are cloudy or structural damage may limit vision recovery. MDPIVisual Evoked Potentials (VEP)
Measures the signal sent from the eye to the brain; useful when optic nerve or severe retinal disease is suspected and to help predict visual outcome after complex surgery. MDPI
E. Imaging Tests
B-Scan Ultrasound
Uses sound waves to see inside the eye when the view is blocked by blood, scar, or opaque media; critical to detect retinal detachment, mass, or globe shape after trauma. MDPIOptical Coherence Tomography (OCT)
A non-contact scan that gives cross-sectional images of the retina. It shows how the retina is attached, thickness changes, or traction. FrontiersMDPIFluorescein Angiography
Dye is injected into the bloodstream to highlight blood flow in the retina; helpful to see leaking vessels, ischemia, or neovascular membranes in diabetic or inflammatory disease. MDPIComputed Tomography (CT) Scan
Used in trauma to assess bone fractures, foreign bodies, and gross globe integrity when the eye has been injured severely. ResearchGate
Non-Pharmacological Treatments / Supportive Therapies
These are therapies, lifestyle changes, and procedural supports that help the eye before, during, or after use of FCVB or in managing the underlying retinal/vitreous disease. Each is described with purpose and mechanism in simple terms.
Posture positioning after surgery – After retinal procedures, maintaining certain head positions (e.g., face-down) helps the internal tamponade press the retina in the correct place so it can stick back. This uses gravity to aid healing. Mayo Clinic
Low vision rehabilitation – When vision is reduced, trained therapists use magnifiers, lighting techniques, and strategies to help patients use remaining vision better. This improves daily function even if full vision isn’t restored. PMC
Visual training / eye exercises – For some conditions, guided activities can help the brain adapt to visual changes and optimize use of residual sight. This includes tracking, focusing, and contrast enhancement drills. MDPI
Protective eyewear – After trauma or during recovery, wearing safety glasses prevents further injury or accidental pressure on the healing eye. Simple physical protection reduces risk of re-injury.
Control of systemic health (blood sugar / blood pressure) – Healthy overall body circulation supports eye healing; high blood sugar or blood pressure can worsen retinal disease or delay recovery. MDPI
Smoking cessation – Smoking reduces blood flow and increases oxidative stress in eye tissues, impairing healing and increasing the chance of complications. Stopping helps oxygen and nutrients reach the retina. EatingWell
UV and blue light protection – Sunglasses that block harmful light reduce chronic oxidative stress to retinal cells, helping preserve the remaining vision. Verywell Health
Nutritional optimization (whole foods) – Eating foods rich in antioxidants and healthy fats supports retinal health from the inside. A balanced diet helps the eye resist damage and recover more effectively. EatingWell
Ocular surface lubrication (artificial tears) – Keeping the front of the eye moist prevents irritation that can distract from healing and cause reflex inflammation.
Stress management / mental health support – Chronic stress can raise inflammation and lower compliance; managing stress supports overall recovery and encourages adherence to treatment plans. MDPI
Light modulation (glare reduction) – Using tinted lenses or adjusting lighting reduces discomfort from bright lights, helping patients use vision more effectively during recovery.
Patient education and adherence coaching – Teaching patients their role (e.g., medication use, positioning) increases successful outcomes.
Eye movement optimization (saccade training) – For peripheral vision loss or scotomas, training can help patients learn to scan and compensate. PMC
Avoidance of heavy lifting / Valsalva maneuvers – Sudden pressure spikes in the eye can dislodge the retina or tamponade; avoiding straining protects the repair.
Sleep hygiene with eye protection – Preventing inadvertent pressure during sleep (e.g., not sleeping on the operated side) supports healing.
Use of low vision aids (magnifiers, high-contrast devices) – Enhances function in daily tasks while structural recovery is ongoing. PMC
Controlled gradual activity resumption – Slowly returning to normal activities avoids sudden eye stress and helps the body adapt without compromising the repair.
Regular monitoring with fundus photography or OCT – Imaging without drugs helps detect early problems before they become serious.
Avoiding eye rubbing – Physical manipulation can interfere with healing or displace internal devices; keeping hands away protects the eye.
Environmental optimization (reducing dust, allergens) – Clean air reduces irritation and secondary inflammation that could interfere with ocular healing.
Drug Treatments
These drugs are commonly used to treat inflammation, infection, neovascularization, and complications in eyes needing FCVB or undergoing vitreoretinal surgery.
Dexamethasone intravitreal implant (0.7 mg) – A corticosteroid placed inside the eye to reduce inflammation and macular edema. It suppresses immune response, decreasing swelling and helping stabilize vision. Common side effects include increased intraocular pressure and cataract progression. ScienceDirect
Triamcinolone acetonide (intravitreal injection) – Another steroid used for similar purposes (non-infectious uveitis, edema). It reduces inflammation by blocking inflammatory pathways. Risks include eye pressure rise and potential infection if sterile technique fails. PMC
Anti-VEGF agents (e.g., bevacizumab, ranibizumab) – These block vascular endothelial growth factor to reduce abnormal vessel growth and leakage in conditions like proliferative vitreoretinopathy or neovascular complications. Used in adjunct when neovascularization threatens retinal stability. AAO
Topical antibiotics (e.g., moxifloxacin drops) – Given perioperatively to reduce surface bacterial load and minimize risk of endophthalmitis (intraocular infection). Mechanism: inhibit bacterial DNA synthesis or cell wall components.
Intravitreal antibiotics (e.g., vancomycin + ceftazidime) – Used prophylactically in high-risk situations or as treatment for suspected infection; they directly kill intraocular bacteria. American Society of Retina Specialists
Carbonic anhydrase inhibitors (e.g., oral acetazolamide or topical dorzolamide) – Used to control elevated intraocular pressure which can be a complication post-surgery. They reduce aqueous humor production.
Beta-blocker eye drops (e.g., timolol) – Another pressure-lowering class to protect optic nerve function when pressure is high.
Non-steroidal anti-inflammatory drops (e.g., nepafenac) – Reduce surface inflammation, helpful in early postoperative period to control mild inflammatory symptoms without steroid side effects.
Systemic steroids (short-course oral prednisolone) – In some inflammatory retinal conditions, systemic suppression is needed briefly to reduce damage from aggressive inflammation.
Anti-fibrotic modulators under investigation (e.g., agents targeting proliferative vitreoretinopathy pathways) – Emerging drugs aim to reduce scar formation that can pull on the retina, such as those modulating transforming growth factor-beta activity. PMC
Dietary Molecular Supplements
These are nutrients and small molecules shown to support retinal/ocular health. Dosages are typical ranges; individual needs should be personalized with a doctor.
Lutein (10–20 mg/day) – A carotenoid concentrated in the macula that filters blue light and acts as an antioxidant, protecting photoreceptors from light-induced damage. PMC
Zeaxanthin (2–10 mg/day) – Works with lutein to protect the macula; filters high-energy light and reduces oxidative stress. Verywell Health
Omega-3 fatty acids (DHA/EPA, 500–1000 mg/day) – Support retinal cell membrane health, reduce inflammation, and help tear production; important for overall ocular function. Dryeye RescuePMC
Vitamin C (500–1000 mg/day) – Antioxidant that scavenges free radicals in ocular tissues, supporting collagen and vascular stability. NCCIH
Vitamin E (200–400 IU/day) – Protects lipid membranes in photoreceptors from oxidative damage. Works synergistically with vitamin C. NCCIH
Zinc (25–80 mg/day) – Helps transport vitamin A from the liver to the retina and is part of antioxidant enzymes; shown in AREDS formulations to slow AMD progression. NCCIH
Copper (2 mg/day, often paired with zinc) – Prevents zinc-induced copper deficiency; part of antioxidant defense. NCCIH
Astaxanthin (4–12 mg/day) – A potent antioxidant that may protect retinal cells from oxidative stress and improve microcirculation. (Emerging evidence from eye health supplement reviews.) Verywell Health
Alpha-lipoic acid (300–600 mg/day) – Antioxidant that regenerates other antioxidants and may help with neuroprotection in retinal disease. Verywell Health
Bilberry extract (standardized anthocyanins, 80–160 mg/day) – May improve microvascular circulation and act as an antioxidant, though evidence is mixed; often included in ocular health blends. Verywell Health
Note: Many ocular supplement formulas (like AREDS2) combine several of these; evidence supports benefits in specific diseases like AMD, not necessarily for all vitreoretinal conditions. NCCIH
Regenerative / Stem Cell or Advanced Biologic Approaches
These are emerging or investigational therapies aimed at healing or replacing damaged retinal structures.
Retinal pigment epithelium (RPE) stem cell implants (e.g., OpRegen) – Transplantation of RPE cells derived from stem cells to replace damaged RPE in diseases like geographic atrophy or severe degeneration; they aim to restore metabolic support to photoreceptors.
Human embryonic stem cell-derived RPE transplantation – Trials have explored placing healthy RPE under damaged retina to rescue photoreceptors; mechanism is cell replacement and trophic support.
Mesenchymal stem cell intraocular injections – Thought to release growth factors and anti-inflammatory cytokines, potentially providing neuroprotection and a niche for tissue stabilization in degenerative conditions.
Neurotrophic factor delivery (e.g., CNTF implants) – Sustained release of factors like ciliary neurotrophic factor to support survival of retinal neurons; acts by promoting cell health and reducing apoptosis.
Gene-modified cell therapy – Cells engineered to secrete protective proteins (e.g., anti-angiogenic or anti-inflammatory) implanted in or near retina to create a therapeutic microenvironment.
Biologic scaffolds with cellular seeding – Use of biodegradable scaffolds seeded with retinal progenitor or support cells to structurally replace damaged layers and guide tissue regeneration. PMC
Note: Most of these are under clinical investigation and not standard of care yet; they aim at hard-to-heal damage where conventional repair (including FCVB) has limited effect.
Related Surgeries / Procedures

Frequently Asked Questions (FAQs)
What conditions need a Foldable Capsular Vitreous Body?
Advanced retinal detachment, severe ocular trauma, eyes dependent on silicone oil, and some complicated vitreoretinal pathologies. ResearchGatePubMedHow is FCVB different from regular silicone oil tamponade?
FCVB contains the tamponade inside a capsule, limiting direct contact with eye tissues, reducing emulsification, and offering longer-term stability. Lippincott JournalsIs FCVB safe?
Studies show relatively low complication rates with long-term implantation, and it is generally well tolerated in difficult cases. TVSTLippincott JournalsWill my vision fully recover after FCVB?
Vision outcome depends on the underlying damage; the device mainly preserves structure. Some patients regain partial vision, but severe prior injury may limit full recovery. TVSTCan FCVB be removed later?
Yes, in many cases it can be explanted if indicated, though the decision is individualized based on eye stability. ResearchGateHow long does it stay in the eye?
It can remain for years; some studies report safe use over multi-year follow-up without major issues. Lippincott JournalsWhat are common complications?
Possible complications include infection, elevated intraocular pressure, and failure of retinal reattachment, but rates are lower than some alternatives in complex eyes. ResearchGateLippincott JournalsDo I still need medications after FCVB surgery?
Yes. Anti-inflammatory drops, antibiotics, and pressure-lowering medications may be needed to support healing and prevent complications. PMCAmerican Society of Retina SpecialistsCan I have an MRI with FCVB?
Most FCVBs are silicone-based and generally MRI-compatible, but specific device labeling and surgeon guidance must be confirmed before scanning. (Patient should verify with their implant documentation.)How soon can I resume normal activity?
Gradual return is advised; heavy lifting or straining is avoided initially. Exact timing comes from the surgeon based on healing. Mayo ClinicDoes diet really affect eye healing?
Yes. Antioxidants, omega-3s, and stable metabolism help tissues recover and resist further damage. EatingWellNCCIHAre supplements necessary?
Supplements help when diet alone is insufficient, especially in high-risk retinal conditions (e.g., AREDS2-type formulations). They are not magic cures but supportive. NCCIHWhat if I have trouble with head positioning after surgery?
Therapists and support tools (pillows, reminders) can help; adherence improves surgical success. Mayo ClinicWill I need low vision rehab?
If vision does not fully recover, rehabilitation improves quality of life by teaching how to function with remaining sight. PMCCan underlying systemic disease affect outcomes?
Yes. Poorly controlled diabetes or high blood pressure can worsen healing and increase risk of further detachments. Good systemic control is essential. MDPI
