Panophthalmitis

Panophthalmitis is a very severe eye infection and inflammation. In this condition, almost every part of the eye is involved. The cornea, conjunctiva, anterior chamber, iris, lens, vitreous, retina, choroid, and the white wall of the eye (sclera) can all be affected. The swelling and infection can also spread to the tissues around the eye in the orbit. Panophthalmitis is not a mild eye problem. It is a true emergency. It can destroy eye tissues quickly, blind the eye, and sometimes can even threaten life if germs spread to the blood. Immediate hospital care is needed.

Panophthalmitis is a severe, vision-threatening infection that inflames every layer of the eyeball and often spreads beyond the eye into the orbit (the tissues around the eye). It can start as an infection inside the eye (endophthalmitis) or arrive through the bloodstream from infections elsewhere in the body. Because it involves the whole globe and nearby tissues, it can progress quickly, cause permanent vision loss, and may even threaten life if not treated immediately. This is a true medical emergency that needs urgent hospital care by an ophthalmologist, often with infectious-disease and ENT support. EyeWikiCleveland Clinic

It is helpful to compare it with endophthalmitis. In endophthalmitis, germs infect the inside of the eye, mainly the vitreous and aqueous parts. In panophthalmitis, the whole eye is inflamed, including the outer coats and often the orbit. Because more structures are involved, pain, swelling, and damage are usually worse and faster in panophthalmitis. Most cases are caused by bacteria. Some cases are due to fungi. Rarely, a mix of different germs can be found. The germs get into the eye through a wound, after surgery, after a severe corneal ulcer, or they travel in the blood from another infected body site.

When the eye becomes infected, immune cells rush to fight the germs. Pus and toxins build up. Blood vessels leak fluid. Pressure inside the eye may go up. The optic nerve and the retina can be damaged. The sclera and the cornea can weaken and even melt or perforate. Nearby orbital tissues can also get inflamed, so the eye may bulge out and the eyelids may be very swollen. Because of all this, vision drops quickly, sometimes to no light perception. This is why rapid diagnosis and urgent treatment are essential.

Below you will find very simple, long explanations of the types, causes, symptoms, and diagnostic tests used to identify panophthalmitis. Each part is written in clear, plain English to help any reader understand this dangerous eye condition.

Types of Panophthalmitis

1. Acute panophthalmitis
   This is the sudden form. It appears over hours to a few days. Pain, swelling, redness, and vision loss happen quickly. It is usually due to aggressive bacteria or severe corneal infection that spreads into and around the eye.

2. Subacute or chronic panophthalmitis
   This is slower. It develops over days to weeks. Pain and redness may be less dramatic at first, but the damage still grows. Certain fungi or less aggressive organisms can cause this pattern, especially in people with weak immune systems.

3. Exogenous panophthalmitis
   “Exogenous” means germs enter from the outside. This happens after trauma (like a cut to the eye), after eye surgery (such as cataract surgery), after intravitreal injections, or after a severe corneal ulcer that perforates and lets germs into deeper tissues.

4. Endogenous panophthalmitis
   “Endogenous” means germs come from the blood. A person has an infection in another part of the body, like a skin abscess, infected heart valve, urinary tract infection, or liver abscess. Germs enter the blood and seed the eye. This type is more common in people with diabetes, IV drug use, long hospital stays, or immune suppression.

5. Bacterial panophthalmitis
   This is the most common type. Germs such as Staphylococcus aureus, Streptococcus species, and gram-negative bacteria like Pseudomonas or Klebsiella can cause very fast tissue destruction. Pseudomonas, for example, can melt the cornea quickly.

6. Fungal panophthalmitis
   This is less common but very serious. Fungi like Candida, Aspergillus, or Mucor can infect the eye. Fungal infections often occur in immunocompromised people, in people with long antibiotic courses, central lines, or after major surgery. Fungal disease can be slower, but it can also invade deep tissues, including blood vessels, and is harder to treat.

7. Polymicrobial panophthalmitis
   Sometimes more than one organism is present. Mixed infections can happen after dirty trauma, farm injuries, or delayed care. Polymicrobial infections can be more destructive and need broad testing and treatment.

8. Post-traumatic panophthalmitis
   This happens after an open-globe injury or intraocular foreign body. Soil, plant material, or metal fragments can carry virulent bacteria or fungi. Delayed wound closure or lack of prompt antibiotics raises the risk of rapid, severe infection.

9. Post-surgical panophthalmitis
   This follows eye surgery or injection. It is rare, since surgeons use sterile techniques, but it can occur. It often starts as endophthalmitis and then spreads to all coats of the eye if the infection is very aggressive or treatment is delayed.

10. Keratitis-related panophthalmitis
    A severe corneal ulcer can perforate and let germs into the eye. This risk is higher in contact lens-related Pseudomonas keratitis, uncontrolled eyelid disease, dry eye with exposure, or corneal melts due to autoimmune disease or topical steroid abuse.

---

Causes of Panophthalmitis

1. Open-globe trauma
   A cut or puncture lets outside germs enter. Dirty objects and delayed wound cleaning increase risk. Germs multiply quickly and spread through the eye layers.

2. Intraocular foreign body
   A small piece of metal, wood, or plant material lodged inside the eye carries germs. The foreign body also irritates tissues, making infection easier.

3. Post-cataract or other eye surgery infection
   Despite sterile practices, rare infections can occur. If the infection is severe or not caught early, it can extend to panophthalmitis.

4. Post-intravitreal injection infection
   Injections for retinal diseases are common. Rarely, germs from the ocular surface enter during the procedure and cause aggressive infection.

5. Severe bacterial keratitis with perforation
   A deep corneal ulcer can break through, allowing germs to move inward. Pseudomonas ulcers can do this very quickly.

6. Contact lens-related corneal ulcer
   Poor hygiene, overnight wear, or contaminated lens cases can cause dangerous ulcers that may progress to panophthalmitis if not treated promptly.

7. Endogenous seeding from bloodstream infection
   Any severe infection (such as staph bacteremia) can seed the eye, especially in diabetes, IV drug use, cancer, or immune suppression.

8. Klebsiella liver abscess with eye seeding
   In some regions, Klebsiella infections of the liver can spread to the eye. This can cause very destructive endogenous panophthalmitis.

9. Candida bloodstream infection
   People with long hospital stays, central venous catheters, TPN, or prolonged antibiotics can develop fungal seeding to the eye.

10. Mucormycosis (rhino-orbital-cerebral) extension
    In uncontrolled diabetes or immune suppression, Mucor fungi can invade sinuses, orbit, and eye, causing necrotizing panophthalmitis.

11. Severe bleb-related infection
    After glaucoma surgery, a filtering bleb can get infected (blebitis) and progress to intraocular infection and beyond.

12. Severe dacryocystitis spreading to the globe
    Infection in the tear sac can sometimes track toward the eye and worsen a pre-existing corneal problem, increasing risk of deeper spread.

13. Uncontrolled eyelid or ocular surface disease
    Lid margin infections, severe blepharitis, or exposure keratopathy can lead to corneal breakdown and secondary deep infection.

14. Topical steroid misuse on the cornea
    Long or unsupervised steroid use can weaken corneal defenses, making it easier for aggressive bacteria or fungi to penetrate.

15. Chemical or thermal injury to the eye
    Burns damage the surface, reduce natural defenses, and can lead to ulceration and deep secondary infection.

16. Severe dry eye with corneal melt
    In some autoimmune conditions, the cornea can thin and melt, then perforate, letting germs in.

17. Severe gonococcal conjunctivitis
    Neisseria gonorrhoeae can penetrate an intact cornea very fast, especially in newborns or untreated adults, causing deep infection.

18. Herpes keratitis with bacterial superinfection
    A herpetic ulcer damages the cornea. Bacteria then invade and may lead to perforation and deeper infection if not treated.

19. Delayed treatment of endophthalmitis
    If endophthalmitis is not treated promptly or the germ is very virulent, it can extend to panophthalmitis.

20. Systemic immune suppression
    Steroids, chemotherapy, HIV/AIDS, transplant medicines, and uncontrolled diabetes lower defenses, making deep eye infection more likely and more severe.

Symptoms of Panophthalmitis

1. Severe, deep eye pain that does not go away and is worse with touch or movement.

2. Rapid loss of vision, sometimes down to only light perception or no light perception.

3. Marked redness of the eye and the whole white part (360-degree redness).

4. Eyelid swelling that can close the eye.

5. Pus or thick discharge from the eye that can be yellow or green.

6. Sensitivity to light (bright light hurts).

7. Tearing and constant watering.

8. Eye feels hard or very tender, and even a light touch is painful.

9. Bulging of the eye (proptosis) or the feeling the eye is being pushed out.

10. Painful or limited eye movements, sometimes the eye does not move well.

11. Headache on the same side as the infected eye.

12. Fever, chills, or feeling very unwell, which may suggest bloodstream infection.

13. Cloudy cornea or a white spot on the cornea that looks like an ulcer.

14. White or yellow fluid level inside the eye (hypopyon) seen by the doctor.

15. Nausea or vomiting, sometimes due to severe pain or raised eye pressure.

Important: These symptoms are a medical emergency. If panophthalmitis is suspected, the person should go to the hospital immediately for urgent eye care.

Diagnostic Tests

Below are the tests commonly used to diagnose and assess panophthalmitis. They help the eye team understand how deep the infection is, which germ is causing it, and whether nearby tissues are involved. Some tests are done at the bedside, some are manual bedside checks, some are lab or pathology tests, two are electrodiagnostic tests, and some are imaging tests.

A) Physical Exam–Based Tests

1. Visual acuity test (bedside vision check)
   The doctor asks you to read letters or count fingers or detect light. This tells how much vision is left. In panophthalmitis, vision is often severely reduced. Tracking this helps the team understand changes over time.

2. External inspection of eyelids and orbit
   The doctor looks for eyelid swelling, redness, skin warmth, and bulging of the eye. This shows if the infection has spread to the orbit, which is common in panophthalmitis and makes the condition more dangerous.

3. Pupil exam (including RAPD check)
   The doctor shines a light to see how the pupils react. A poor reaction or a relative afferent pupillary defect (RAPD) can suggest optic nerve or severe retinal involvement. This is common when the infection is deep and destructive.

4. Ocular motility assessment
   You will be asked to look in different directions. Pain and limited motion suggest inflammation in the orbit or muscle involvement. This supports the diagnosis of panophthalmitis and helps separate it from purely internal infections.

5. Slit-lamp biomicroscopy
   The doctor uses a microscope with bright light to look at the cornea, anterior chamber, iris, and lens. They can see corneal ulcers, infiltrates, hypopyon, and other signs of severe inflammation. This exam guides urgent decisions.

B) Manual Bedside Tests

Safety note: If an open-globe injury is suspected, avoid any pressure on the eye. In that case, some manual tests below are deferred until the eye is stabilized.

6. Fluorescein staining with Seidel test
   A dye drop is placed on the cornea. With blue light, the doctor checks for ulcers and for leaking aqueous fluid (the Seidel sign) that shows a perforation. This is vital in keratitis-related cases.

7. Digital estimation of globe firmness (very gentle, only if safe)
   With eyelids closed, a very gentle touch compares firmness between the two eyes. A very firm, painful eye can suggest raised pressure from severe inflammation. This is not done if perforation is suspected.

8. Retropulsion test (only if no open globe)
   The doctor gently presses on the closed eyelids to feel resistance behind the eye. High resistance and pain suggest orbital inflammation or an abscess. This supports the diagnosis of panophthalmitis with orbital spread.

9. Eyelid eversion and fornix sweep
   The eyelid is gently turned over to look for foreign material, pus, or hidden ulcers. A sterile applicator can sweep the fornix to remove debris and collect samples. This helps find the source and improve hygiene.

C) Laboratory and Pathology Tests

10. Complete blood count (CBC) with differential
    This test looks for high white blood cells and the type of white cells. It supports systemic infection and helps in overall assessment.

11. Inflammatory markers (CRP and ESR)
    These show the level of body inflammation. Very high levels suggest a strong systemic response and are useful to monitor response to therapy.

12. Blood cultures
    Blood samples are taken to grow germs. If the infection is endogenous, the same organism may be found in the blood and eye. Early cultures help target antibiotics or antifungals.

13. Aqueous or vitreous tap for Gram stain and culture
    A small sample from inside the eye is collected by an eye surgeon under strict sterile technique. Gram stain quickly suggests bacteria type. Culture identifies the exact organism and antibiotic sensitivities, guiding precise treatment.

14. Fungal tests (KOH prep, fungal culture, or fungal biomarkers)
    If fungus is suspected, the sample is checked with KOH or other stains, and fungal cultures are done. Sometimes antigen tests or beta-D-glucan help. These tests are essential when Candida, Aspergillus, or Mucor is possible.

15. Molecular tests (PCR, 16S/18S rRNA, or multiplex panels)
    These tests look for germ DNA or RNA. They can be faster, especially if the patient was already on antibiotics or if cultures are negative. PCR helps confirm rare organisms and supports early therapy adjustments.

D) Electrodiagnostic Tests

16. Electroretinography (ERG)
    ERG measures the electrical activity of the retina in response to light. In panophthalmitis, the retina may be severely damaged. A very reduced or flat ERG suggests poor retinal function and limited visual potential. ERG is not urgent in the acute painful phase but can guide prognosis when the eye is stabilizing.

17. Visual evoked potentials (VEP)
    VEP records the electrical response in the brain when the eye sees a visual pattern. If the signal is very weak or absent, it suggests optic nerve or severe retinal pathway damage. Like ERG, VEP is mainly prognostic, not for immediate emergency decisions.

E) Imaging Tests

18. B-scan ocular ultrasound
    This is very useful when the cornea is cloudy and the doctor cannot see in. It shows vitreous opacities, membranes, retinal detachment, choroidal detachment, abscesses, and even foreign bodies. It helps assess how widespread the disease is.

19. CT scan of orbit and sinuses
    CT shows bony walls, orbital fat, muscles, sinuses, and foreign bodies (especially metal). It can detect orbital abscess, air, bone erosion, and sinus disease that may be the source. CT is quick and very helpful in emergencies.

20. MRI of orbit and brain (with contrast when safe)
    MRI shows soft tissues in great detail. It can reveal optic nerve involvement, intracranial extension, cavernous sinus thrombosis, and fungal spread. MRI is especially useful when Mucor or Aspergillus is suspected, because it shows tissue invasion.

Non-Pharmacological Treatments (therapies & other care)

1. Emergency hospital admission. Purpose: immediate monitoring and intervention; Mechanism: brings surgical, imaging, and drug therapy under one coordinated team without delay. EyeWiki

2. Rigid eye shield (not a patch). Purpose: protect a possibly open or friable globe; Mechanism: prevents pressure and further contamination.

3. Head-of-bed elevation. Purpose: ease venous congestion; Mechanism: reduces orbital pressure and discomfort.

4. Strict “no rubbing” and minimal manipulation. Purpose: avoid rupture or extrusion; Mechanism: lowers mechanical stress on inflamed tissues.

Drug Treatments

Important: Exact dosing must be individualized by your treating team based on weight, kidney function, organism, and local protocols. Intravitreal doses below are standard starting points used widely in emergency care.

1. Intravitreal Vancomycin (glycopeptide; 1 mg/0.1 mL as a single intravitreal injection; may repeat per response). Purpose: rapid gram-positive coverage (incl. MRSA). Mechanism: blocks cell-wall synthesis. Notable risks: rare retinal toxicity; HORV has been reported with intracameral vancomycin after cataract surgery, not typical with intravitreal use. NCBI

2. Intravitreal Ceftazidime (third-gen cephalosporin; 2.25 mg/0.1 mL intravitreal). Purpose: strong gram-negative coverage (incl. Pseudomonas). Mechanism: cell-wall inhibition. Risks: allergy, rare retinal irritation. NCBI

3. Intravitreal Amikacin (aminoglycoside; 0.4 mg/0.1 mL as beta-lactam allergy alternative). Purpose: gram-negative coverage when ceftazidime cannot be used. Mechanism: ribosomal inhibition. Risks: retinal toxicity (macular infarction) → now used cautiously. NCBI

4. Intravitreal Amphotericin B (5–10 µg/0.1 mL) for suspected/confirmed fungal infection. Purpose: fungicidal in vitreous. Mechanism: binds ergosterol, creates pores. Risks: retinal toxicity at higher doses; systemic amphotericin has infusion-related and kidney side effects. PMCJAMA Network

5. Intravitreal Voriconazole (50–100 µg/0.1 mL). Purpose: modern antifungal with good retinal penetration. Mechanism: inhibits fungal ergosterol synthesis (CYP-51). Risks: transient visual disturbances systemically; intravitreal use is generally well tolerated. PMCEyeWiki

6. Systemic Antibiotics (when orbital spread or endogenous source is suspected): examples include IV vancomycin (weight-based), IV ceftazidime 2 g q8h (per EVS), or alternatives such as piperacillin-tazobactam or meropenem based on risk and cultures. Purpose: treat orbital cellulitis/sepsis and distant source. Mechanism: pathogen-specific. Note: In post-operative exogenous endophthalmitis, EVS found systemic antibiotics did not change final vision; in endogenous disease, systemic + intravitreal therapy reduces eye-removal risk. Risks: drug-specific (renal with vanc/aminoglycosides, etc.). NCBI

7. Topical Fortified Antibiotics (adjunct when cornea/bleb/entry wound is infected): vancomycin 25–50 mg/mL alternating with tobramycin 14–15 mg/mL hourly initially. Purpose: sterilize surface and entry tract. Mechanism: very high local concentrations. Risks: surface toxicity/irritation. EyeWikiGlobalRPHAAO

8. Cycloplegics (e.g., atropine 1%, typically 1–3×/day as directed). Purpose: pain relief by relaxing ciliary muscle and preventing synechiae. Mechanism: anticholinergic blockade. Risks: blurred vision, photophobia. NCBI

9. Corticosteroids (adjunct only, with caution): e.g., intravitreal dexamethasone 0.4 mg/0.1 mL or systemic prednisone ~1–1.5 mg/kg/day after infection control starts; avoid in fungal disease. Purpose: dampen the destructive inflammatory cascade. Risks: steroid-induced glaucoma, hyperglycemia, worse fungal growth. NCBIEyeWiki

10. Systemic Antifungals (when fungus suspected/confirmed): examples include IV amphotericin B or voriconazole (oral/IV) chosen by organism, site, and patient factors. Purpose: eradicate bloodstream or extraocular fungal sources and seedings. Mechanism: fungicidal/fungistatic per agent. Risks: amphotericin—renal toxicity; voriconazole—hepatic/visual side effects.

Dietary “Molecular” Supplements

Important: Supplements do not treat panophthalmitis and must never delay surgery or antibiotics. If your doctor agrees and there are no contraindications, these nutrients may support immune function and wound healing during recovery. Stick to safe ranges and avoid megadoses.

1. Vitamin A (e.g., 700–900 mcg RAE/day from diet/supplements combined; avoid exceeding UL without supervision). Function: supports barrier tissues and immune function. Mechanism: regulates epithelial integrity and immune signaling. Caution: fat-soluble—toxicity at high doses. Office of Dietary Supplements+1

2. Vitamin C (typically 75–90 mg/day; many take 200–500 mg/day short term). Function: collagen synthesis, antioxidant support, helps iron absorption. Mechanism: cofactor for collagen enzymes; scavenges oxidants. Caution: GI upset at very high doses. Office of Dietary Supplements+1

3. Vitamin D (individualized; many adults use 600–800 IU/day; avoid >4,000 IU/day unless prescribed). Function: immune modulation, bone/overall health. Mechanism: nuclear receptor signaling. Caution: toxicity at high blood levels. Office of Dietary Supplements+1

4. Zinc (generally 8–11 mg/day; UL 40 mg/day for adults). Function: enzyme and immune function, epithelial repair. Mechanism: cofactor in DNA repair and immunity. Caution: chronic high intake lowers copper. Office of Dietary Supplements+1

5. Selenium (RDA ~55 mcg/day; UL 400 mcg/day). Function: antioxidant enzymes (glutathione peroxidases). Mechanism: selenoprotein activity reduces oxidative stress. Caution: selenosis with excess. Office of Dietary SupplementsThe Nutrition Source

6. Omega-3 fatty acids (EPA/DHA) (food-first: fish; typical supplements 250–1,000 mg/day EPA+DHA if approved). Function: resolve inflammation; support retinal health generally. Mechanism: pro-resolving lipid mediators. Office of Dietary Supplements+1

7. Protein/essential amino acids (food-first; supplements only if intake is poor). Function: tissue repair. Mechanism: substrate for collagen and immune cell proteins.

8. Arginine (in some nutrition formulas). Function: wound healing support. Mechanism: nitric-oxide pathway and collagen synthesis.

9. Glutamine (if diet is inadequate). Function: fuel for rapidly dividing immune and gut cells. Mechanism: supports lymphocyte and enterocyte metabolism.

10. Probiotics (strain-specific; ask your clinician, especially if immunocompromised). Function: gut barrier and immune signaling. Mechanism: microbiome modulation.

(Again: these are supportive only and must never delay definitive surgical/antimicrobial care.)

Regenerative / Stem-Cell Drugs

For panophthalmitis, there are no approved “immunity-booster,” regenerative, or stem-cell drugs that treat the eye infection itself. In fact, immunosuppressive or experimental regenerative therapies are not appropriate in acute eye infections. If a patient’s immune system is unusually low (for example, severe neutropenia), doctors sometimes treat the underlying immune deficit—but that is not a direct treatment for panophthalmitis and is only done under specialist care. Here are six context-only items your team may consider for underlying conditions, not for the eye infection itself:

1. Filgrastim (G-CSF) to correct severe neutropenia if present (commonly 5 mcg/kg/day SC; exact dosing varies by indication and product). Function: raises neutrophil counts; Mechanism: stimulates marrow granulopoiesis; Note: not a treatment for eye infection—used when low neutrophils impair any infection control. FDA Access Data

2. Pegfilgrastim (long-acting G-CSF) for chemotherapy-related risk, per oncology guidance. Function/Mechanism: as above. NCBI

3. IVIG only when a patient has a documented antibody deficiency or selected sepsis contexts under specialist protocols (typical replacement 400–600 mg/kg every 3–4 weeks; sepsis use remains debated and patient-specific). Function: provides pooled antibodies; Mechanism: neutralization/opsonization. PMC+1Ejinme

4. Tetanus immunization after perforating trauma—this prevents tetanus, not eye infection, but is critical trauma care. CDC

5. Tight glucose control with standard antidiabetic therapy when indicated (to support overall immunity/wound healing).

6. Optimization of nutrition (protein, vitamins/minerals as above) if malnourished.

Bottom line: none of these are “eye-regenerating” cures for panophthalmitis. The proven pillars are intravitreal therapy, systemic therapy when indicated, and timely surgery. NCBIEyeWiki

Surgeries & Procedures

1. Vitreous tap & intravitreal injection (“tap and inject”)
   What: tiny samples of aqueous/vitreous are taken, then intravitreal antibiotics ± antifungals are injected.
   Why: to identify the pathogen quickly and deliver very high drug levels right where the infection is. NCBI

2. Pars plana vitrectomy
   What: microsurgery to remove infected vitreous gel and membranes.
   Why: reduces microbial and inflammatory load, improves oxygenation, allows better drug distribution, and can improve outcomes in severe cases (especially if presenting vision is only light perception). NCBI

3. Drainage of orbital abscess / sinus surgery (if present)
   What: surgical drainage by oculoplastics/ENT when imaging shows an abscess or sinus source.
   Why: source control—removing pockets of pus is essential for cure. Radiopaedia

4. Evisceration
   What: removal of the contents of the eye while leaving the scleral shell; an orbital implant may be placed later.
   Why: definitive source control when the eye is unsalvageable and infection threatens the orbit or the patient’s health; often preferred for speed and cosmesis when safe (radiology must exclude scleral abscess). EyeWiki

5. Enucleation
   What: complete removal of the entire eyeball including a segment of optic nerve.
   Why: ensures entire globe removal when needed for infection control or other concerns; chosen based on surgeon judgment, imaging, and patient factors. EyeWiki

Prevention Tips

1. Eye protection at work/sports to prevent trauma.

2. Prompt care for any eye injury—open globes are emergencies.

3. Contact-lens hygiene and no overnight wear unless specifically prescribed.

4. Treat eyelid/lacrimal infections early (blepharitis, dacryocystitis).

5. Peri-operative antisepsis (povidone-iodine) and sterile technique for all intraocular procedures (your surgeon’s role). NCBI

6. Control diabetes and chronic diseases.

7. Keep vaccinations up to date; assess tetanus status after penetrating injuries. CDC

8. Avoid contaminated water exposure with contact lenses (pools, hot tubs).

9. Do not delay treatment if eye pain/redness/vision loss occurs after surgery or injections.

10. Hand and eye hygiene—don’t touch/rub eyes, especially when irritated.

---

When to See a Doctor

• Immediately for any severe eye pain, sudden vision drop, pus, fever with an eye infection, or symptoms after surgery, trauma, or intravitreal injection. Go to an emergency department with ophthalmology coverage if you can’t see an eye doctor at once. Delays increase the chance of permanent vision loss and the need for eye-removal surgery. NCBI

What to Eat & What to Avoid

What to eat (supportive, not curative):

1. Lean proteins (fish, eggs, poultry, legumes) for tissue repair.

2. Colorful fruits/vegetables for vitamin A/C and antioxidants (citrus, berries, leafy greens, carrots, sweet potatoes). Office of Dietary Supplements+1

3. Healthy fats including omega-3 sources (fish, flax, walnuts). Office of Dietary Supplements

4. Whole grains for steady energy.

5. Hydration (water, broths) to support recovery.

What to avoid (while acutely ill):

1. Alcohol and smoking—they impair healing and immunity.
2. Excess sugar—worsens glycemic control in diabetes.
3. Unpasteurized or raw foods (e.g., raw milk, undercooked meats/sushi) if you’re immunocompromised—reduce infection risk.
4. High-dose, unsupervised supplements, especially vitamin A/D or zinc above the UL—risk of toxicity. Office of Dietary Supplements+2Office of Dietary Supplements+2
5. Herbal products that thin blood (e.g., very high-dose fish oil, ginkgo) before surgery unless cleared by your team.

Frequently Asked Questions

1) Is panophthalmitis the same as endophthalmitis?
No. Endophthalmitis is infection inside the eye; panophthalmitis means infection of all eye coats and often the orbit, which is more severe. EyeWiki

2) How fast can vision be lost?
Sometimes within hours to days. That’s why urgent hospital care is essential.

3) Do I always need surgery?
Not always, but many severe cases need tap & inject, vitrectomy, or eye removal if the globe is unsalvageable to control infection. NCBIEyeWiki

4) What are the first drugs doctors give?
Typically intravitreal vancomycin plus ceftazidime right away; if fungus is suspected, an intravitreal antifungal is added. Systemic antibiotics are added for orbital spread or endogenous sources. NCBI

5) Are steroids safe?
Sometimes—as an adjunct after antimicrobial therapy begins and not for fungal infections. The team weighs risks and benefits carefully. NCBI

6) Can eye drops alone cure this?
No. Intravitreal therapy (inside the eye) is the cornerstone; drops are only adjuncts for surface sources such as corneal ulcers or wounds. NCBI

7) Why do doctors order a CT scan?
To check for orbital abscess, sinus disease, or foreign bodies and to guide surgery. CT is fast and first-line for urgent orbital infection. Radiopaedia

8) If I had a penetrating injury, do I need a tetanus shot?
Doctors will assess tetanus status and vaccinate if needed according to CDC wound guidance. CDC

9) Will I need systemic antifungals?
Only if fungus is suspected/confirmed or there is systemic fungal disease—your team decides based on cultures, imaging, and risk factors. PMC

10) How often are intravitreal injections repeated?
Repeat dosing depends on the organism, response, and protocols; some cases need repeat injections over 48–72 hours. Clinical Microbiology and InfectionNCBI

11) Is there any role for “immune boosters” or stem cells?
No for the eye infection itself. Managing underlying immune problems (like neutropenia) may be necessary but is not a substitute for surgery/antibiotics. FDA Access Data

12) Can the infection spread to the brain?
Untreated orbital infections can spread; that’s another reason urgent, aggressive care is mandatory. Radiopaedia

13) If the eye must be removed, what’s next?
Your team will discuss evisceration vs enucleation and later prosthesis fitting for cosmesis and function. EyeWiki

14) What is the long-term outlook?
Because panophthalmitis is severe, visual prognosis is often poor, especially with virulent organisms or late presentation—but prompt treatment improves outcomes and may prevent life-threatening spread. NCBI

15) How can I prevent this from ever happening again?
