Periorbital Necrotizing Fasciitis (PNF)

Periorbital (or periocular) necrotizing fasciitis is a rare but extremely dangerous skin and soft-tissue infection that attacks the tissue layers just under the skin around the eyelids and the eye socket. “Necrotizing” means “causing tissue death,” and “fasciitis” means “inflammation and infection of the fascia,” which are the thin sheets of tissue that separate and support muscles and other structures. In this condition, bacteria spread quickly along these tissue planes, cutting off blood flow and destroying skin and deeper tissues. Even though the eyelids and face have a rich blood supply—which usually helps fight infection—this particular infection can still move fast and cause serious problems, including loss of vision, loss of the eye, or even death if not treated urgently. It is a surgical emergency. NCBIPubMedWiley Online LibraryNature

Periorbital necrotizing fasciitis is a fast-moving, flesh-destroying bacterial infection that attacks the soft tissues around the eye (eyelids, brows, cheek, and sometimes the orbit). It spreads along the thin sheets of tissue called fascia, cutting off blood supply and causing the skin and deeper tissues to die (necrosis). Because blood flow collapses, the infection can outrun the body’s defenses and antibiotics, so emergency surgery to remove dead tissue plus broad-spectrum IV antibiotics is the standard of care. Without rapid treatment, people can lose vision, the eye, or even their life. Mortality for necrotizing fasciitis overall is high; in the periorbital region it’s lower than in limbs but still serious, and vision loss is not uncommon. NCBIwebeye.ophth.uiowa.edu

A helpful way to remember this illness is: it looks like “cellulitis” at first, but gets worse very quickly, the pain is often severe and “out of proportion” to what you can see on the skin, and dead or dying skin can appear later with dark patches or blisters. Around the eyes, swelling can be dramatic, and the infection can sometimes spread into the orbit (the bony eye socket), putting the eye and vision at risk. While periorbital cases may have somewhat better survival than infections on the arms or legs, they still carry a risk of blindness and a small but real risk of death. PubMed

Bacteria get into the eyelid or nearby facial skin through a small break—this could be a cut, an insect bite, a pimple that was squeezed, a surgical wound, or spread from a nearby infection such as sinusitis or a blocked tear sac. Once inside, certain aggressive bacteria release toxins and enzymes that help them travel quickly along the thin tissue sheets. As they spread, tiny blood vessels clot off, the tissue loses its blood supply, and the skin and soft tissues die. This “runaway” effect is why the illness moves fast and why treatment must be swift. NCBI

Types

There are two useful ways to think about “types” for this condition: by germs and by location/severity.

A. By germs (microbiology typing)
Doctors often group necrotizing fasciitis by the mix of bacteria involved:

1. Type I (polymicrobial) – more than one kind of bacterium at the same time—usually a mix of aerobic (need oxygen) and anaerobic (do not need oxygen) bacteria. This is common in head and neck infections. hopkinsguides.com

2. Type II (monomicrobial) – usually Group A Streptococcus (Strep pyogenes), sometimes with Staphylococcus aureus (including MRSA). This type can be very fast-moving. hopkinsguides.com

3. Type III – water-associated bacteria such as Vibrio vulnificus, often after marine exposure or wounds in warm seawater; these can be extremely aggressive. Cleveland Clinic

4. Type IV – fungal causes (rare), usually in people with poor immunity. Around the eye, angioinvasive fungi (like mucormycosis) are a different disease category but can mimic necrotizing infection in terms of tissue death and urgency. AAO

B. By location/severity in and around the eye

1. Preseptal (periorbital) disease – infection is in front of the orbital septum (a thin barrier in the eyelid). This is the more common periocular form and is still dangerous because it can spread. EyeWiki

2. Postseptal (orbital) spread – infection has gone behind the septum into the eye socket. This raises the risk of vision loss, eye movement problems, bulging of the eye, and spread to the brain. EyeWiki

Causes

Below are twenty real-world ways the infection can begin. Think of them as triggers or entry points for bacteria. Some are minor, but they matter because the bacteria involved can be very aggressive.

1. Small cuts or scratches on the eyelid or nearby face (nails, jewelry, rough rubbing). Cleveland Clinic

2. Insect bites that are scratched open. Cleveland Clinic

3. Pimples, styes, or boils on the eyelid that are squeezed or manipulated, allowing bacteria to dive deeper. EyeWiki

4. Surgical wounds near the eye (e.g., eyelid surgery, tear-duct surgery). PMC

5. Facial trauma (falls, sports injuries) with skin breaks that get contaminated. PMC

6. Sinus infections that spread to the orbit or eyelids. EyeWiki

7. Dental or gum infections that extend into the facial planes. EyeWiki

8. Blocked tear sac (dacryocystitis) that ruptures or spreads. EyeWiki

9. Animal or human bites around the eye. Cleveland Clinic

10. Water exposure of open wounds (lakes, ocean, hot tubs) leading to water-borne bacteria like Vibrio. Cleveland Clinic

11. Foreign bodies (e.g., plant splinters) that carry bacteria under the skin. NCBI

12. Skin conditions (eczema, dermatitis) that crack the skin barrier. NCBI

13. Shaving, threading, or plucking eyebrows/eyelashes that nick the skin. EyeWiki

14. IV drug use with contamination that seeds nearby facial tissue (less common around the eye but possible). NCBI

15. Recent chickenpox (varicella) in children, which can be linked to severe skin infections. Radiopaedia

16. Diabetes mellitus, which raises risk by weakening immune defenses (a cause in the sense of enabling infection to take hold). NCBI

17. Long-term steroid use or other immunosuppression, which lowers the body’s ability to fight infection. PubMed

18. Obesity and poor circulation, which reduce tissue oxygen and healing. NCBI

19. Alcohol misuse, which impairs immune function and wound healing. NCBI

20. Hospital or postoperative contamination despite best efforts, particularly with resistant bacteria like MRSA. hopkinsguides.com

Symptoms

Here are fifteen common features. Not everyone has all of them, and some appear as the disease advances. The “red flags” are pain out of proportion, very rapid worsening, and dark or dying skin.

1. Severe pain that feels “too much” for what the skin looks like early on. This mismatch is a classic warning sign. NCBI

2. Rapid swelling of the eyelids and surrounding face over hours, not days. PubMed

3. Redness that spreads quickly and edges that seem to “march” across the skin. NCBI

4. Skin color changes to dusky, purple, or gray patches; later, black areas (necrosis). NCBI

5. Blisters or bullae filled with clear, brown, or bloody fluid. NCBI

6. “Wooden-hard” feeling when you press the swollen skin (firmness from deep fascial infection). NCBI

7. Crackling under the skin (crepitus) from gas produced by bacteria (not always present). NCBI

8. Numbness or decreased sensation over the skin as nerves die (a late sign). NCBI

9. Fever, chills, and feeling very unwell, which suggest systemic illness. NCBI

10. Foul-smelling discharge from wounds or areas of dead skin. NCBI

11. Severe eyelid tenderness to light touch, worse than typical cellulitis. NCBI

12. Drooping, tight, or tense eyelids that may be difficult to open. EyeWiki

13. Bulging of the eye (proptosis) if the infection extends behind the septum into the orbit. EyeWiki

14. Painful or limited eye movements (ophthalmoplegia) and double vision, also suggesting orbital involvement. EyeWiki

15. Blurred vision or vision loss, which is an emergency and requires immediate specialist care. PubMed

Diagnostic tests

Below are twenty tests, grouped by category. Very important: no single test “rules it out.” Doctors use the whole picture—history, exam, labs, and imaging—and, if in doubt, they explore the tissue surgically, because delayed treatment can be devastating. Imaging helps, but it must not postpone urgent surgery when the diagnosis is strongly suspected. PMCAJR American Journal of Roentgenology

A) Physical exam tests

1) Vital signs check (fever, heart rate, blood pressure, breathing).
This looks for whole-body illness (sepsis). High fever, very fast heart rate, fast breathing, or low blood pressure suggest a dangerous systemic response and the need for urgent care in hospital. It does not diagnose necrotizing fasciitis by itself, but it tells the team how sick the patient is and how quickly to act. NCBI

2) Pain-out-of-proportion assessment.
The clinician gently examines the eyelids and surrounding skin while asking about pain. In necrotizing fasciitis, pain is often severe even when skin changes still look “mild,” because the deeper tissue planes are being destroyed. This mismatch is a classic red flag. NCBI

3) Skin inspection for color change, bullae, and necrosis.
Doctors look for dusky patches, purple or gray discoloration, fragile blisters (bullae), and black, dead skin. These visual signs point strongly to necrotizing infection rather than simple cellulitis. NCBI

4) Palpation for “woody” firmness and crepitus.
A firm, board-like feel suggests the deeper fascia are involved. If gas is present, gentle pressure may produce a crackling sensation. These clues raise suspicion for necrotizing fasciitis. NCBI

5) Focused ocular exam (visual acuity, pupils, eye movements, proptosis).
Checking vision with a near card or Snellen chart, looking for a relative afferent pupillary defect (RAPD), assessing eye movements, and noting any eye bulging help decide if infection has spread behind the septum into the orbit, which raises the risk of vision loss and intracranial spread. EyeWiki

B) Manual (bedside) tests

6) “Finger test” / “probe-to-fascia” bedside exploration.
With local anesthesia, a small incision is made to reach the fascia. In necrotizing fasciitis, the fascia often feels slippery and easily separated by a blunt probe, with gray, thin, “dishwater” fluid and little bleeding from dead tissue. This quick bedside test can confirm suspicion and prompt immediate surgery. EyeWikiNCBI

7) Gentle skin traction to look for undermining.
The clinician gently lifts the edge of discolored skin; if it lifts away from the underlying tissue easily with poor bleeding, that suggests tissue death beneath. This is a quick, practical sign supporting the diagnosis when combined with other findings. NCBI

8) Capillary refill/blanch test over eyelid skin.
Pressing and releasing the skin should bring quick pink color back in healthy tissue. Slow or absent refill suggests poor blood flow from vascular clotting in necrotizing fasciitis. It is not specific, but together with other signs it supports the diagnosis. NCBI

9) Bedside mapping of sensation with a cotton tip.
Areas of numbness or reduced feeling indicate nerve injury from tissue death, which tends to appear later in the course and signals a more advanced infection. NCBI

C) Laboratory and pathological tests

10) Complete blood count (CBC) with differential.
High white blood cells suggest infection; very high counts or a left shift can appear in severe disease. Low platelets can point to sepsis-related clotting problems. The CBC helps grade severity but is not specific. NCBI

11) C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).
These are inflammation markers that tend to be high in necrotizing fasciitis. Very high CRP can raise suspicion. Again, they support but do not prove the diagnosis. NCBI

12) Serum chemistries (sodium, creatinine, glucose) and lactate.
Low sodium (hyponatremia), rising creatinine (kidney stress), high glucose (especially in diabetes), and elevated lactate (poor tissue perfusion) point to severe systemic illness and a higher risk course. NCBI

13) Blood cultures.
Blood cultures may grow the causative bacteria, guiding antibiotic choice. A negative culture does not rule out the disease. hopkinsguides.com

14) Wound swab/aspirate for Gram stain and culture.
Sampling fluid or tissue from the leading edge of infection can identify the bacteria (for example, Group A Strep, Staph aureus/MRSA, or a mix of aerobic and anaerobic organisms), which helps tailor antibiotics. Polymicrobial growth suggests Type I disease. hopkinsguides.com

15) Tissue biopsy/histopathology.
A small sample viewed under the microscope shows dead fascia, neutrophil invasion, thrombosed vessels, and sometimes visible bacteria. Histology is considered a gold standard confirmation, but treatment should not wait for these results when the clinical picture is clear. NCBI Some clinicians calculate a score called LRINEC from routine labs to estimate risk of necrotizing fasciitis. However, studies show mixed performance, and a low score can miss cases. It can be one piece of information, but clinical judgment and imaging/surgical exploration matter most. PMCScienceDirect

D) Electrodiagnostic / monitoring tests

16) Electrocardiogram (ECG).
Severe infections stress the heart. ECG helps detect rhythm problems or strain in very sick patients. It does not diagnose necrotizing fasciitis but is part of safe care for unstable patients. NCBI

17) Pulse oximetry (oxygen saturation).
A finger sensor tracks oxygen levels continuously. In advanced infection with sepsis, oxygen levels can fall; this guides urgent supportive care. Again, this supports the evaluation but does not confirm the disease itself. NCBI

E) Imaging tests

18) Ultrasound of eyelid/orbit (bedside if needed).
Ultrasound can show thickened fascial layers, turbid fluid tracking along tissue planes, and bright echoes with “dirty” shadowing if gas is present. It is quick and available in the emergency department and can help distinguish abscess from cellulitis. Radiopaedia

19) Contrast-enhanced CT of the orbits and sinuses.
CT is fast and shows fascial thickening, fat stranding, fluid collections, and soft-tissue gas if present. It maps how far the infection has spread, whether the orbit is involved, and whether sinuses or deeper spaces are affected. CT guides both urgency and surgical planning. AJR American Journal of Roentgenology

20) MRI of the orbits/brain with contrast.
MRI is slower but best for soft-tissue detail. It can outline inflammation along fascia, pick up early deep involvement, and help evaluate the orbit and intracranial structures if spread is suspected. MRI is very helpful when CT is unclear and the patient is stable enough to undergo the scan. PMC

Non-Pharmacological Treatments (therapies & other supports)

1. Immediate surgical debridement (source control)
   Purpose: remove all dead tissue so antibiotics and blood flow can reach healthy areas.
   Mechanism: cutting away necrotic tissue stops bacterial spread, reduces toxins, and restores perfusion. Urgent, sometimes within hours; repeat debridements are typically needed. Infectious Diseases Society of America

2. Serial “second-look” operations
   Purpose: reassess edges and remove any newly necrotic tissue every 24–36 hours until the wound is clean.

   Purpose: stabilize airway, breathing, and circulation; treat shock.
   Mechanism: IV fluids, vasopressors if needed, oxygen/ventilation to maintain organ perfusion. PMC

4. Tight but safe blood-sugar control
   Purpose: high glucose fuels bacteria and weakens immunity.
   Mechanism: insulin protocols target ~140–180 mg/dL in sepsis to reduce complications while avoiding hypoglycemia. PMC

5. Early, high-protein nutrition
   Purpose: supply calories and protein to rebuild tissue and support immunity.
   Mechanism: guidelines suggest ~1.2–2.0 g/kg/day (ASPEN) or ~1.3 g/kg/day (ESPEN) protein during critical illness. Enteral feeding is preferred when feasible. nutritioncare.orgESPN

6. Eye surface protection

   Purpose: save vision when orbit pressure is dangerously high.
   Mechanism: Lateral canthotomy/cantholysis immediately when IOP ≥40 mmHg with vision risk—do not delay. EyeWiki

8. Negative-pressure wound therapy (NPWT, “VAC”)
   Purpose: speed granulation and manage exudate once infection is controlled.
   Mechanism: controlled suction removes fluid, improves perfusion, and promotes healthy tissue growth. JOMS

9. Multidisciplinary team care
   Purpose: coordinate oculoplastics, ENT/maxillofacial, plastics, ID, ICU, wound care.
   Mechanism: rapid, coordinated decisions reduce delays and complications. aast.org

10. Hyperbaric oxygen therapy (HBOT) — selectively
    Purpose: adjunct in some centers after debridement to improve oxygen delivery and hinder anaerobes/toxin effects.
    Mechanism: high-pressure oxygen may enhance leukocyte killing and inhibit clostridial toxins; evidence is mixed and mostly observational, availability is limited; never delay surgery for HBOT. PMC+1PLOS

11. Meticulous wound care & dressing changes
    Purpose: keep wounds clean and moist to heal.
    Mechanism: removes slough, protects granulation tissue, and reduces bacterial load.

   Dose: 3.375–4.5 g IV q6–8h (extended/continuous infusion often used in sepsis).
   Purpose: broad polymicrobial coverage including anaerobes.
   Mechanism: cell-wall inhibition plus β-lactamase blocking.
   Side effects: diarrhea, rash, renal injury with other nephrotoxins, sodium load. Infectious Diseases Society of AmericaFDA Access Data

2. Meropenem (carbapenem)
   Dose: 1 g IV q8h (extended infusion common in ICU).
   Purpose: very broad coverage of gram-negatives (including ESBL), gram-positives, anaerobes.

   Side effects: seizures (rare, higher risk in CNS disease/renal failure), GI upset. Infectious Diseases Society of America

3. Cefepime (4th-generation cephalosporin) ± Metronidazole
   Dose: Cefepime 2 g IV q8–12h plus Metronidazole 500 mg IV/PO q8h.
   Purpose: alternative broad regimen (cefepime covers many gram-negatives; metronidazole adds anaerobes).
   Mechanism: cell wall synthesis inhibition; metronidazole causes DNA strand breaks in anaerobes.
   Side effects: encephalopathy with cefepime (high dose/renal failure), metallic taste with metronidazole. Infectious Diseases Society of America

4. Vancomycin (glycopeptide)
   Dose: 15–20 mg/kg IV q8–12h with AUC-guided monitoring.
   Purpose: MRSA and resistant gram-positive coverage in empiric therapy.
   Mechanism: blocks cell wall synthesis at D-Ala-D-Ala.
   Side effects: nephrotoxicity (monitor levels), “red man” syndrome if infused fast. Infectious Diseases Society of AmericaNCBI

5. Linezolid (oxazolidinone) — alternative to vancomycin for MRSA or for GAS toxin suppression if clindamycin cannot be used
   Dose: 600 mg IV/PO q12h.
   Purpose: gram-positive coverage including MRSA; good tissue penetration; may reduce toxin production.
   Mechanism: binds 50S ribosome, halting protein synthesis.
   Side effects: thrombocytopenia (esp. >10–14 days), serotonin-drug interactions, neuropathy (long courses). NCBI

6. Clindamycin (lincosamide) — key adjunct when GAS suspected/confirmed
   Dose: 600–900 mg IV q8h.
   Purpose: suppresses streptococcal toxin production and works even in stationary-phase bacteria.
   Mechanism: 50S ribosomal inhibitor; reduces exotoxin synthesis.
   Side effects: C. difficile diarrhea, rash, liver enzyme elevation. Infectious Diseases Society of AmericaPMC

7. Penicillin G (narrow β-lactam) — once GAS is proven
   Dose: 4 million units IV q4h (or continuous infusion) plus clindamycin.
   Purpose: definitive therapy for invasive GAS.
   Mechanism: cell wall synthesis inhibition; clindamycin adds toxin suppression.

8. Ceftriaxone (3rd-gen cephalosporin) ± Metronidazole (if using a cephalosporin-based regimen)
   Dose: Ceftriaxone 2 g IV q24h; Metronidazole 500 mg q8h.
   Purpose: broad gram-negative/positive coverage with added anaerobes.
   Mechanism/SEs: as above; ceftriaxone can cause biliary sludging. Infectious Diseases Society of America

9. Daptomycin (lipopeptide) — MRSA alternative (not for lung infections)
   Dose: 6–8 mg/kg IV q24h.
   Purpose: for MRSA when vancomycin can’t be used or is failing.
   Mechanism: membrane depolarization causing rapid bactericidal effect.
   Side effects: myopathy (monitor CPK).

10. Empiric antifungal therapy only if fungal NF is suspected (rare)
    Example: Liposomal amphotericin B or an echinocandin per ID/ophthalmology advice.
    Purpose/Mechanism/SEs: targeted at proven fungi; significant toxicity; not routine in typical PNF. Society of Critical Care Medicine (SCCM)

Key principle: For suspected NF, IDSA recommends empiric coverage with either (a) vancomycin or linezolid plus piperacillin-tazobactam (or a carbapenem), or (b) vancomycin/linezolid + ceftriaxone + metronidazole. For confirmed GAS, use penicillin + clindamycin. Infectious Diseases Society of America

Important note on “Immunity boosters” and stem-cell drugs

There are no approved “hard immunity boosters” or stem-cell drugs for periorbital necrotizing fasciitis. Using unproven products can delay life-saving surgery/antibiotics and cause harm, so I can’t recommend them. What clinicians may consider in specific situations is below—only under specialist care:

1. IVIG (intravenous immunoglobulin) for streptococcal toxic shock syndrome (STSS)
   Dose (typical): 1–2 g/kg divided over 1–2 days.
   Function/Mechanism: may neutralize GAS superantigens; evidence is mixed and IDSA does not recommend routine use in NF without STSS. Risks: thrombosis, kidney injury (sucrose-stabilized products), aseptic meningitis. Infectious Diseases Society of AmericaPMC

2. Hydrocortisone for refractory septic shock
   Dose: 200 mg/day IV (e.g., 50 mg IV q6h) if shock persists despite fluids/vasopressors.
   Function/Mechanism: restores vascular responsiveness in catecholamine-refractory shock; not an infection cure. Risks: hyperglycemia, delirium, infection risk with long use. PMC

3. Insulin infusion protocols in ICU
   Target: maintain glucose about 140–180 mg/dL.
   Function/Mechanism: improves immune function and lowers infection complications while avoiding hypoglycemia. Risks: hypoglycemia without close monitoring. PMC

4. G-CSF (filgrastim) only if true neutropenia from another cause
   Function/Mechanism: raises neutrophil counts; not routine for NF and not recommended for general use in NSTI. Risks: bone pain, leukocytosis. Infectious Diseases Society of America

5. Anticoagulation for DVT prophylaxis (e.g., LMWH)
   Function: prevents clots in immobilized, septic patients. Risks: bleeding; individualized.

6. Evidence-guided nutrition (not “boosters”)
   Function: adequate protein/energy supports immune cells and collagen formation; see supplements below. Risks: over-feeding; use dietitian guidance. ESPN

Dietary & Molecular Supplements

Always discuss supplements with your medical team; some interact with antibiotics or affect surgery.

1. Protein (food or medical nutrition)
   Dose: aim for ~1.2–2.0 g/kg/day total protein in critical illness if kidneys allow.
   Function/Mechanism: supplies amino acids for collagen and immune cells. nutritioncare.org

2. Arginine-enriched oral nutrition
   Dose: as part of specialized wound-healing formulas per label.
   Function/Mechanism: arginine becomes conditionally essential under stress, supporting nitric oxide signaling and collagen deposition; evidence suggests improved wound healing when used with full nutrition. Lippincott Journals

3. Glutamine (specialist-guided)
   Dose: per ICU dietitian if indicated (routine use varies by guideline).
   Function/Mechanism: fuel for enterocytes and immune cells; may support gut barrier.

4. Omega-3 fatty acids (EPA/DHA)
   Dose: commonly 1–2 g/day combined EPA/DHA in recovery phases.
   Function/Mechanism: anti-inflammatory lipid mediators that may modulate excessive inflammation.

5. Vitamin C
   Dose: typical diet 75–90 mg/day; in wound healing, clinicians may use higher oral doses short-term.
   Function/Mechanism: collagen cross-linking and antioxidant effects; deficiency impairs wound healing. Office of Dietary Supplements

6. Zinc
   Dose: short-term supplementation often 15–30 mg elemental zinc/day if deficient; avoid >40 mg/day long term (risk of copper deficiency).
   Function/Mechanism: DNA/protein synthesis and immune function critical for skin repair. Office of Dietary Supplements

7. Vitamin A
   Dose: only if deficient and only with clinician guidance (fat-soluble; toxicity risk).
   Function/Mechanism: epithelial integrity and immune modulation.

8. Vitamin D
   Dose: replete deficiency per local protocol (e.g., cholecalciferol weekly loading).
   Function/Mechanism: immune modulation; bone/skin health.

9. Selenium
   Dose: as part of balanced nutrition when deficient.
   Function/Mechanism: antioxidant enzymes (glutathione peroxidase) supporting immune function.

10. Probiotics (case-by-case)
    Function/Mechanism: may help gut balance during prolonged antibiotics; not a treatment for NF and use with caution in the critically ill.

These are adjuncts to surgery/antibiotics, not substitutes. Dietitian-supervised plans are best. ESPN

Surgical Procedures

1. Urgent wide debridement
   Procedure: under anesthesia, surgeons open the infected areas and remove all dead tissue until healthy bleeding edges are reached.
   Why: only way to stop spread and let antibiotics work. Often repeated. Infectious Diseases Society of America

2. Repeat debridements (“second-look” every 24–36 h)
   Procedure: staged returns to the OR.
   Why: NF can advance after the first surgery; staged removal prevents resurgence. Infectious Diseases Society of America

3. Lateral canthotomy/cantholysis for OCS
   Procedure: a small cut at the outer eye corner to release tight tissues and drop eye pressure quickly.
   Why: protects the optic nerve when pressure/vision are threatened (IOP ≥40 mmHg or classic signs). EyeWiki

4. Reconstructive skin grafts or local/regional flaps (after infection control)
   Procedure: once wounds are clean, surgeons cover defects using skin grafts or flaps (e.g., forehead/cheek flaps) to restore eyelid function and protect the cornea.
   Why: to blink, protect the eye, and improve appearance. PubMed

5. Orbital exenteration (rare, last-resort)
   Procedure: removal of the eye and orbital contents when infection destroys the orbit uncontrollably.
   Why: to save life when infection is not controlled by debridement and antibiotics. This is uncommon in PNF. webeye.ophth.uiowa.eduTaylor & Francis Online

Prevention Tips

1. Clean and cover any cuts around the face/eyelids promptly.

2. Treat sinus, dental, or skin infections early.

3. Manage diabetes well (keep glucose in target range). SpringerLink

4. Avoid swimming or hot tubs with open wounds (marine bacteria risk).

5. Don’t share towels/cosmetics; keep makeup brushes and contact lens cases clean.

6. Stop smoking and limit alcohol to support immunity and healing.

7. Seek care promptly if facial redness/swelling spreads fast or pain is severe.

8. Follow post-procedure care after eyelid/orbital surgery exactly.

9. Maintain good nutrition—adequate calories and protein aid skin defenses. nih.org

10. Household hygiene when someone has confirmed GAS (handwashing; don’t share personal items). CDC

---

When to See a Doctor

• Right now if you have sudden, severe eyelid/facial pain, fast-spreading swelling/discoloration, blisters or black skin, high fever, confusion, or feel faint.

• Urgently if vision blurs, the eye bulges or won’t move, pupils look unequal, or lids feel rock-hard—these can signal orbital compartment syndrome.

• Immediately if “cellulitis” isn’t improving on antibiotics within hours and pain is worsening—NF cannot wait. PMC

What to Eat and What to Avoid

1. Prioritize protein at each meal (eggs, fish, poultry, legumes, dairy) to rebuild tissue. nutritioncare.org

2. Add vitamin-C-rich foods (citrus, kiwi, bell pepper) to support collagen formation. Office of Dietary Supplements

3. Include zinc sources (meat, seafood, beans, nuts, fortified cereals) for wound healing. Office of Dietary Supplements

4. Stay well-hydrated unless you’re fluid-restricted by your doctors.

5. Eat enough calories—healing burns energy; a dietitian can set targets. PMC

6. Limit added sugars to help control blood glucose during recovery. ScienceDirect

7. Avoid alcohol during healing; it impairs immunity and nutrition.

8. Avoid smoking/vaping; they reduce oxygen to tissues and delay healing.

9. Be cautious with herbal megadoses (garlic, ginkgo, ginseng) pre-op—they may affect bleeding; always clear supplements with your surgeon.

10. Work with a dietitian for a personalized, safe high-protein plan. ESPN

Frequently Asked Questions

1) Is periorbital necrotizing fasciitis contagious?
It’s not spread by casual contact, but the bacteria (especially Group A Strep) can spread person-to-person. Good hand hygiene and not sharing personal items help. CDC

2) How is it different from cellulitis?
Cellulitis is a non-necrotizing skin infection; PNF kills tissue and spreads faster, often with pain out of proportion, blisters, and skin anesthesia. NCBI

3) Do antibiotics alone cure it?
Usually no. Surgery plus antibiotics is the standard because blood flow to dead tissue is gone. Infectious Diseases Society of America

4) How fast does it spread?
It can progress within hours; that’s why urgent care is critical. CDC

5) Will I lose my eye or vision?
Many patients do not, especially with rapid treatment, but some lose vision from ischemia or need extensive reconstruction. Exenteration is rare and last-resort. webeye.ophth.uiowa.edu

6) What imaging test is best?
CT with contrast is fast and shows gas/fluid tracks; MRI is very sensitive but takes longer. Imaging must not delay surgery if NF is strongly suspected.

7) Is the LRINEC score reliable?
It can miss cases; low sensitivity in studies means a low score does not rule out NF. Clinical judgment and early exploration matter most. PMC

8) Why do doctors add clindamycin even with other antibiotics?
It reduces toxin production from GAS and works even when bacteria are not rapidly dividing—useful in NF. PMC

9) What is orbital compartment syndrome and why the rush?
Dangerously high pressure inside the orbit can blind you within hours; lateral canthotomy/cantholysis can save vision. EyeWiki

10) What is hyperbaric oxygen therapy—do I need it?
