Orbital Aspergillosis

Orbital aspergillosis is a fungal infection around or inside the eye socket. The eye socket is also called the orbit. The orbit has the eyeball, the optic nerve, eye muscles, fat, blood vessels, and nerves. The fungus here is usually Aspergillus, a mold found in dust, soil, old buildings, air vents, and decaying plants. We all breathe in Aspergillus spores every day, but most healthy people clear them easily. When the fungus grows in the nose and sinuses, it can press on or invade nearby tissues. The sinuses sit right next to the orbit, so the infection may extend into the eye socket. In some people, the fungus can invade small blood vessels and cut off blood flow, which can damage the optic nerve and threaten vision. Early recognition is important because delayed diagnosis can lead to blindness or spread to the brain. EyeWikiLippincott Journals

Orbital aspergillosis is a serious fungal infection around the eye. The fungus (Aspergillus) usually starts in the nose and sinuses and then spreads into the orbit (eye socket). This can damage the eye, the optic nerve, nearby blood vessels, and even the brain if not treated fast. Best care is urgent antifungal medicine + surgery to clean infected tissue, with close teamwork between ENT, ophthalmology, infectious diseases, radiology, and critical care. Voriconazole is the usual first-choice drug in many cases of invasive aspergillosis; liposomal amphotericin B is a key alternative, and surgical debridement of infected sinus/orbital tissue is often needed. Treatment typically continues at least 6–12 weeks, and longer if the immune system is still weak. PMCNCBIRadiopaedia

How does the fungus reach the orbit?

Most cases start in the paranasal sinuses (especially the ethmoid and sphenoid sinuses) and then extend through thin bone or natural openings into the orbit. Rarely, infection begins inside the orbit itself, for example after surgery or trauma. The infection can behave in two broad ways: it can sit and cause pressure without invading tissue (non-invasive), or it can penetrate tissues and blood vessels (invasive). The invasive form is the dangerous one because vessel invasion causes tissue death, nerve injury, and chance of spread to the cavernous sinus or brain. Lippincott JournalsPMC

Types of orbital aspergillosis

Doctors use “type” to describe how fast the disease grows, how deeply it invades, and what the immune system is like. Here are the main types in plain language.

1. Allergic fungal sinusitis with orbital push (non-invasive)
   In some people with allergies and nasal polyps, fungus becomes trapped in thick allergic mucus in the sinuses. The fungus is not invading tissue; it is sitting in sticky material. The sinus can expand like a balloon and push on the orbit, causing bulging eyes or double vision. On scans, the sinus content often looks very dense on CT and very dark on certain MRI sequences because of heavy metals within the fungal debris. Radiopaedia

2. Fungal ball (aspergilloma) in a sinus with secondary orbital pressure (non-invasive)
   Here the fungus forms a compact clump (a “ball”) inside one sinus, often the maxillary or sphenoid sinus. It does not invade tissue but can erode bone over time and press toward the orbit, causing pain or vision symptoms. Imaging often shows hyperdense sinus material on CT and T2-dark signal on MRI. AJR American Journal of RoentgenologyRSNA Publications

3. Chronic invasive aspergillosis (slow but invasive)
   This type creeps slowly over months. It often affects people who appear otherwise healthy or only mildly immunocompromised. The fungus invades tissues and small blood vessels and can form granulomas (tight immune cell clusters). People may have long-standing sinus pain, slowly progressive eye pain, double vision, or gradual vision loss. MRI often shows very dark T2 signal in the involved area because of metal deposition in the fungal mass. Radiopaedia+1

4. Granulomatous invasive fungal sinusitis (GIFS) with orbital extension
   This is a variant of chronic invasive disease that can appear in immunocompetent people in some regions. The infection forms granulomas, may destroy bone, and can extend into the orbit. It progresses slowly, so symptoms can be subtle at first but become serious if untreated. PMC

5. Acute fulminant invasive aspergillosis (rapid and aggressive)
   This type happens in people who are significantly immunosuppressed (for example, very low white blood cells, transplants, high-dose steroids, or certain cancers). The fungus invades blood vessels quickly, causing tissue death and sudden vision loss. Symptoms can worsen over hours to days. This is a medical emergency. Oxford AcademicPMC

6. Primary orbital aspergillosis (rare)
   In rare reports, the infection is mainly in the orbit itself without obvious sinus disease. It can mimic tumors or inflammatory diseases of the orbit and usually shows invasive features on pathology. ScienceDirect

7. Sino-orbital apex syndrome due to aspergillus
   When fungus extends to the orbital apex (the tight space where the optic nerve and many eye-moving nerves enter the orbit), patients develop severe pain, vision loss, and multiple cranial nerve palsies. This pattern is sometimes called orbital apex syndrome. EyeWiki

8. Cavernous sinus and skull-base involvement
   In advanced disease, the infection may extend to the cavernous sinus or skull base. This can cause facial numbness, multiple nerve palsies, or stroke-like symptoms if the internal carotid artery is affected. Imaging may show hyperdense tissue on CT and T2 hypointensity on MRI. PMC

Causes and risk factors

“Cause” here means what makes a person more likely to get this infection or what opens the door for the fungus. Often several factors stack up together.

1. Chronic sinus disease
   Long-standing sinus blockage gives fungus a safe, moist space to settle and grow. Thick mucus and swollen linings trap spores and make clearance hard. PMC

2. Uncontrolled diabetes
   High blood sugar weakens immune cells and feeds microbes. In diabetes, blood supply to tissues can be poorer, making it harder for the body to fight and heal. PMC

3. Prolonged or high-dose corticosteroids
   Steroids calm inflammation but also suppress white blood cells, lowering the body’s defenses against molds. Oxford Academic

4. Neutropenia (very low neutrophils)
   Neutrophils are front-line fungal fighters. When counts are very low, invasive aspergillosis risk rises sharply. PMC

5. Hematologic malignancy (e.g., leukemia)
   Cancer of the blood and bone marrow, plus chemotherapy, damages immune function, allowing molds to invade. PMC

6. Stem-cell or solid organ transplant
   Transplant medicines suppress immunity to prevent rejection, but this increases mold risk. Oxford Academic

7. Prolonged ICU care or chemotherapy
   Long hospital stays, chemotherapy, and central lines increase exposure and decrease immunity, opening a window for infection. PMC

8. Chronic granulomatous disease (CGD) or other phagocyte defects
   Inherited problems with neutrophil killing allow Aspergillus to survive and spread. Oxford Academic

9. Long courses of broad-spectrum antibiotics
   Antibiotics disrupt normal flora, and some patients become more vulnerable to fungal overgrowth. (This does not cause Aspergillus directly but shifts the balance.) Oxford Academic

10. Allergic fungal sinusitis and nasal polyps
    Allergic mucus and polyps trap spores. Over time, sinus expansion can press into the orbit. Radiopaedia

11. Fungal ball (aspergilloma) in a sinus
    A dense ball of fungus occupied in one sinus can erode bone and push toward the orbit. RSNA Publications

12. Exposure to heavy dust or renovation sites
    Aspergillus spores float in construction dust. Repeated, heavy exposure raises the chance of sinus colonization.

13. Warm and humid climate
    Warm, damp air favors fungal growth and spore load, which increases exposure. Radiopaedia

14. Prior sinus or orbital surgery
    Any operation that alters drainage or exposes bone can create niches where fungus settles if healing is slow.

15. Corticosteroid nasal sprays used incorrectly or excessively
    Topical steroids can thin local defenses if used too often or without guidance, especially in chronically blocked sinuses.

16. HIV infection with low CD4 counts
    Advanced HIV weakens cellular immunity, and molds can take advantage.

17. Long-term oxygen therapy or ventilators with poor air filtration
    Contaminated air increases spore exposure for people already fragile.

18. Severe viral pneumonia treated with steroids
    Major lung infections plus steroids temporarily weaken antifungal defenses and may increase Aspergillus risk in vulnerable hosts. PMC

19. Smoking and second-hand smoke
    Smoke irritates airway linings, reduces mucus clearance, and can slow immune responses, making it easier for fungi to linger.

20. Older age and poor nutrition
    Age-related immune changes and low protein or vitamin intake can reduce healing and lower resistance to invasive infection.

Common symptoms

1. Deep, boring pain behind the eye
   The pain often starts before visible eye changes. It is deep, constant, and gets worse over days to weeks. Pain is a warning that structures inside the orbit are irritated or compressed. EyeWiki

2. Headache, often around the brow or temple
   The sinuses share walls with the orbit and skull base. Inflammation and pressure there cause dull or throbbing headaches that do not go away with simple pain pills.

3. Nasal blockage or stuffiness
   Many patients have blocked nose, post-nasal drip, or reduced smell. These are clues that the sinuses are involved.

4. Thick or discolored nasal discharge
   Drainage may be yellow-green or brown. Foul odor can appear when fungus and dead tissue collect.

5. Swollen eyelids and puffy tissues around the eye
   Inflamed tissues hold fluid. Lids may look heavy, red, and tender.

6. Red eye (conjunctival injection)
   The white of the eye gets red because nearby vessels are engorged by inflammation.

7. Bulging eye (proptosis)
   Pressure from the sinuses or mass in the orbit pushes the eye forward. This is a key warning sign. Lippincott Journals

8. Double vision
   When eye muscles are inflamed or nerves are affected, the eyes do not move together, and patients see two images.

9. Pain when moving the eyes
   Inflamed muscles hurt on motion. Patients may keep the eye very still to reduce pain.

10. Droopy eyelid or difficulty opening the eye
    If the muscle or nerve that lifts the eyelid is affected, the lid may droop.

11. Reduced or blurred vision
    When the optic nerve is compressed or blood flow is reduced, vision dims. This can be sudden or gradual and may become permanent if not treated quickly. EyeWiki

12. Loss of color brightness (colors look washed out)
    The optic nerve carries color signals. If it is injured, reds and greens look faded.

13. A relative afferent pupillary defect (often noticed by clinicians)
    This is a pupil reaction change that signals optic nerve trouble even before major vision loss.

14. Facial numbness or tingling
    If infection extends to the skull base or cavernous sinus, the trigeminal nerve branches can be affected, causing numbness of the forehead, cheek, or upper lip. PMC

15. Fever and feeling unwell (sometimes mild or absent)
    Not everyone has a fever, especially in chronic cases, but some do, particularly with acute invasive disease. Lippincott Journals

Diagnostic tests — what doctors do and why

Doctors combine history, examination, blood tests, imaging, and tissue diagnosis. The gold standard is biopsy with fungal stains, which shows septate hyphae branching at acute angles typical of Aspergillus. Imaging supports the diagnosis and maps how far it has spread.

A) Physical examination

1. General check and vital signs
   The doctor checks temperature, pulse, blood pressure, and breathing. Fever may indicate active infection. High heart rate or blood pressure changes can reflect pain or stress. The overall look (ill or well) also matters in judging urgency.

2. External eye and eyelid exam
   The clinician looks for redness, swelling, tenderness, bulging, and skin changes. Gentle palpation checks for warmth, firmness, or fluctuation that might suggest abscess.

3. Cranial nerve screening (II through VI)
   The doctor briefly tests vision (II), eye movements (III, IV, VI), lid position (III), and facial sensation (V1/V2). Trouble in these nerves suggests orbital apex or cavernous sinus involvement.

4. Anterior rhinoscopy and sinus tenderness
   With a simple light and speculum, the doctor looks into the front of the nose for polyps, crusts, discharge, and checks for tenderness over the sinuses, which hints at sinus disease next to the orbit.

B) Manual / bedside tests

5. Visual acuity (Snellen chart)
   This is the basic sight test. Any drop from the person’s usual vision is important. Rapid decline, especially with pain, raises concern for optic nerve compromise.

6. Color vision (Ishihara plates)
   Color testing is a sensitive way to pick up early optic nerve dysfunction. Washed-out reds point to nerve injury even if the letter chart is nearly normal.

7. Pupil reactions and the RAPD test
   The swinging-flashlight test looks for a relative afferent pupillary defect (RAPD). If present, it strongly suggests asymmetric optic nerve damage in the painful eye.

8. Eye movement testing (ductions and versions)
   The doctor asks the patient to look in all directions. Painful or limited movements suggest muscle inflammation, apex involvement, or nerve palsy.

9. Confrontation visual fields
   The clinician checks how far the patient can see out to the sides without moving the eyes. Lost or shrunken side vision can mean nerve or chiasm involvement.

10. Nasal endoscopy (flexible scope)
    An ENT specialist often performs this in-clinic. A thin flexible camera is passed gently through the nose to see the sinus openings. The doctor looks for fungal debris, thick mucus, polypoid tissue, or areas suitable for safe biopsy. Endoscopy guides where to take tissue and reduces blind sampling. PMC

C) Laboratory and pathological tests

11. Complete blood count (CBC) with differential
    This test counts white cells, red cells, and platelets. Low neutrophils (neutropenia) mark high invasive mold risk. It also helps detect anemia or thrombocytopenia due to illnesses or treatments. PMC

12. Blood glucose and HbA1c
    High glucose and poor long-term control (HbA1c) point to diabetes, which worsens outcomes and signals a need for urgent infection control. PMC

13. Serum galactomannan (GM) and β-D-glucan (BDG)
    These are fungal cell-wall markers measured in blood. They help in invasive aspergillosis in high-risk patients, especially with lung disease. In localized sino-orbital disease, they can be negative or only weakly positive, so a negative blood test does not rule out orbital disease. PMCOxford Academic

14. Fungal culture from sinus or orbital tissue
    A sample from endoscopic swab, aspiration, or biopsy can be sent for culture. Culture shows which species is present and helps with drug sensitivity. However, cultures can be slow and sometimes negative even when fungus is present.

15. Histopathology of biopsy with special stains (gold standard)
    A small piece of abnormal tissue from the sinus or orbit is examined under a microscope using GMS or PAS stains. In aspergillosis you see thin, septate hyphae that branch at acute angles (about 45°), and in invasive disease you often see angioinvasion (the fungus inside blood vessel walls). This finding confirms the diagnosis. PMCDermNet®+1

D) Electrodiagnostic tests

16. Visual evoked potentials (VEP)
    Small electrodes on the scalp measure how the visual pathway responds to light patterns. If the optic nerve is damaged by pressure or poor blood flow, the signal becomes delayed or smaller. VEP is useful when the exam is difficult or when vision loss is unclear.

17. Electroretinogram (ERG)
    Electrodes measure the retina’s electrical response to light. If vision loss is from optic nerve disease, the ERG may be normal, helping to localize the problem. If the retina is also affected by ischemia, ERG changes point to combined damage.

E) Imaging tests

18. Contrast-enhanced CT scan of the orbits and paranasal sinuses
    CT shows the bony walls and sinus changes very well. Fungal material often looks remarkably dense (hyperattenuating), sometimes with micro-calcifications. CT also shows bony erosion or expansion that explains proptosis. It can detect air-fluid levels, opacified sinuses, and early extension toward the orbit. CT is fast and widely available, so it is often the first imaging test. AJR American Journal of RoentgenologyRSNA Publications

19. MRI of the orbits and brain with gadolinium
    MRI shows soft tissues, nerves, and vessels in detail. Fungal collections and involved tissues are often very dark on T2-weighted images and show variable enhancement after contrast. MRI helps identify optic nerve edema, apical crowding, muscle enlargement, abscess, cavernous sinus involvement, and brain extension. It is crucial when vision is threatened or symptoms suggest apex or skull-base disease. Radiopaedia+1

20. MR or CT angiography/venography for vessel or cavernous sinus assessment
    When there are signs of cavernous sinus thrombosis, multiple nerve palsies, or concern for internal carotid artery involvement, vascular imaging looks for clots, narrowing, or wall invasion. This matters because vessel involvement raises the risk of stroke and calls for urgent, aggressive management. Imaging may show T2-dark lesions at the skull base in invasive cases. PMC

Non-pharmacological treatments

These are in addition to antifungal drugs. In invasive orbital disease, surgery + antifungals is the cornerstone.

1. Urgent endoscopic sinus surgery (debridement).
   Purpose: remove fungal burden, dead tissue, and open drainage pathways.
   Mechanism: lowers microbial load, improves drug penetration and oxygenation, allows repeated cleaning and biopsy. NCBI

2. Targeted orbital debridement (when accessible and vision-saving).
   Purpose: clear focal abscesses or necrotic fat/muscle while trying to preserve structures.
   Mechanism: source control in the orbit without automatically removing the eye. Lippincott Journals

3. Retrobulbar (transcutaneous) amphotericin B injection as an adjunct in selected orbital disease.
   Purpose: deliver high local antifungal levels to the orbit to help halt spread.
   Mechanism: 1 mL injections (often 3.5 mg/mL) into the muscle cone at intervals alongside systemic therapy; evidence is observational but increasingly supportive. Used by specialists only. Lippincott Journalsb-ent.bePMC

4. Repeat endoscopic debridements (“second look”).
   Purpose: remove new necrotic tissue and assess response.
   Mechanism: staged source control reduces relapse and improves drug access. NCBI

5. Reversal of immunosuppression where feasible.
   Purpose: give the patient’s immune system a chance to fight.
   Mechanism: reduce/hold steroids and other immunosuppressants when safe; correct neutropenia with oncology team support. IDSA

6. Tight glucose control (for people with diabetes).
   Purpose: high sugars impair neutrophils and fuel invasive fungal disease.
   Mechanism: insulin protocols and diet to keep glucose near target range. NCBI

7. HEPA-filtered room/clean air precautions in hospital for high-risk patients.
   Purpose: lower airborne spores during recovery.
   Mechanism: high-efficiency filtration and construction dust controls. PMC

8. Sterile saline nasal irrigations after surgery (as directed).
   Purpose: clear debris and crusts, reduce local bioburden.
   Mechanism: isotonic irrigations with distilled/sterile water to avoid contamination. NCBI

9. Eye lubrication and corneal protection.
   Purpose: prevent exposure keratopathy when the eyelids don’t close well.
   Mechanism: frequent ointment/tears, moisture chambers, tape at night.

10. Head elevation and careful pain control.
    Purpose: decrease orbital venous congestion; improve comfort.
    Mechanism: 30–45° bed elevation; avoid heavy cough/strain.

11. Nutrition support (dietitian-guided).
    Purpose: preserve lean body mass and immunity.
    Mechanism: adequate protein and calories; address micronutrient deficits (see food/supplement section below).

12. Monitor for drug toxicity and interactions.
    Purpose: catch liver, kidney, and QT problems early.
    Mechanism: schedule labs and EKGs tied to antifungals; adjust promptly. Pfizer LabelingFDA Access Data

13. Therapeutic drug monitoring (TDM) where appropriate.
    Purpose: ensure antifungal blood levels are in the effective window (e.g., voriconazole).
    Mechanism: measure troughs and titrate dosing (common target ~1–5.5 µg/mL per local practice). DermNet®

14. Sinus/eye protection teaching at home.
    Purpose: reduce re-exposure.
    Mechanism: mold remediation, avoid construction dust, use masks during dusty chores. PubMed

15. Physical/occupational therapy for diplopia or eyelid dysfunction after recovery.
    Purpose: restore function and safety.
    Mechanism: prisms, occlusion therapy, training for ADLs.

16. Psychological support.
    Purpose: reduce anxiety/depression from a sight-threatening illness.
    Mechanism: counseling, peer support.

17. Consider granulocyte transfusions in profound, persistent neutropenia with progressive infection despite therapy (specialist decision).
    Purpose: temporary immune boost.
    Mechanism: donor neutrophils supply phagocytic function for hours–days; limited evidence; risks must be weighed.

18. Consider colony-stimulating factors (G-CSF/GM-CSF) when oncology team recommends.
    Purpose: speed neutrophil recovery.
    Mechanism: stimulates bone marrow to produce neutrophils; adjunct only. IDSA

19. Avoid routine systemic steroids in invasive aspergillosis (they worsen fungal spread), unless treating a separate steroid-responsive condition under specialist guidance.
    Purpose/Mechanism: reduces iatrogenic immunosuppression. IDSA

20. As a last resort: orbital exenteration (removing orbital contents) if infection threatens life and cannot be controlled otherwise.
    Purpose: life-saving source control.
    Mechanism: removes heavily infected tissue; evidence does not clearly show improved survival over conservative strategies when combined care is available, so it’s individualized. Lippincott Journals

Dietary “molecular supplements

Key truth: No vitamin or supplement treats orbital aspergillosis. The only proven treatments are antifungals + surgery + fixing immune problems. That said, good nutrition helps the body recover. Discuss any supplement with your team because azoles interact with many products.

1. Protein (whey/food-based), 1.0–1.5 g/kg/day as advised.
   Function: supports wound healing, immune cells, and repair.
   Mechanism: supplies essential amino acids for antibodies, acute phase proteins.

2. Vitamin D (often 1000–2000 IU/day if deficient; dose per labs).
   Function: supports innate and adaptive immunity.
   Mechanism: modulates antimicrobial peptides and T-cell responses.

3. Vitamin C (e.g., 200–500 mg twice daily with food).
   Function: antioxidant, collagen formation.
   Mechanism: supports neutrophil function and tissue repair.

4. Zinc (8–11 mg/day; avoid high doses >40 mg/day long-term).
   Function: lymphocyte and neutrophil activity.
   Mechanism: cofactor for immune enzymes; excessive zinc can hurt copper status.

5. Selenium (55–100 mcg/day total intake).
   Function: antioxidant enzymes (glutathione peroxidases).
   Mechanism: limits oxidative injury from infection and drugs.

6. Omega-3 fatty acids (≈1 g/day EPA+DHA if approved).
   Function: supports resolution of inflammation.
   Mechanism: pro-resolving mediators; may help with appetite and weight.

7. B-complex (at RDA levels).
   Function: energy metabolism during illness.
   Mechanism: coenzymes for mitochondrial pathways.

8. Probiotics — avoid or use only with specialist approval if you are immunocompromised.
   Why: rare but real cases of bacteremia or fungemia from probiotics in high-risk patients; discuss first. PMC+1

9. Avoid herbal inducers/inhibitors (e.g., St. John’s wort strongly affects CYP3A4) unless your physicians approve.
   Reason: they can lower or raise azole levels unpredictably (your team will check interactions). U.S. Food and Drug Administration

10. Hydration + balanced, food-first plan from a dietitian.
    Function/mechanism: supports kidneys (important with amphotericin) and overall recovery.

For food safety while immunosuppressed, safe-handling rules matter more than extreme “neutropenic diets”: cook meats/eggs well; avoid unpasteurized foods; wash produce; be careful with buffets/salad bars; and follow your team’s local policy. CDCLeukemia & Lymphoma Society

Immune help” options

There are no approved “stem-cell drugs” or regenerative medicines to boost immunity against Aspergillus. What exists are carefully selected immunomodulators used by specialists on a case-by-case basis:

1. Reduce or stop immunosuppressive drugs (if safe).
   Function: lets your own immunity recover.
   Mechanism: fewer steroid/calcineurin effects → better neutrophil/macrophage action. IDSA

2. G-CSF (filgrastim) / GM-CSF to correct chemotherapy-induced neutropenia.
   Function: speeds neutrophil recovery.
   Mechanism: stimulates marrow; used per oncology protocols. IDSA

3. Interferon-gamma (IFN-γ) — highly selected adjunct.
   Function: boosts macrophage killing.
   Mechanism: cytokine priming; evidence limited to case series/selected hosts. DermNet®

4. Granulocyte transfusions for profound, persistent neutropenia with progressive infection despite therapy.
   Function: short-term neutrophil replacement.
   Mechanism: donor granulocytes circulate for hours–days. Risks and benefits carefully weighed.

5. Good glycemic control in diabetes.
   Function: improves neutrophil function.
   Mechanism: lowers glycation-related dysfunction and vascular compromise. NCBI

6. Nutritional rehabilitation (dietitian-guided).
   Function: maintains immune competence.
   Mechanism: adequate protein, calories, and micronutrients (see above).

Surgeries

1. Endoscopic sinus debridement (FESS).
   Why: remove infected/necrotic sinus tissue, open drainage, get biopsies. First-line surgical step. NCBI

2. Orbital abscess drainage / focal debridement via endoscopic or external approach.
   Why: evacuate pus, reduce pressure on the optic nerve, and remove necrotic pockets. Lippincott Journals

3. Retrobulbar amphotericin B injections (adjunct).
   Why: deliver local antifungal in early/mild-moderate orbital involvement to attempt globe preservation. PMC

4. Optic nerve decompression (rare, selected).
   Why: relieve compressive ischemia at the orbital apex when imaging and exam suggest entrapment.

5. Orbital exenteration (last resort).
   Why: life-saving removal of infected orbital contents when the infection is overwhelming and not controlled by other means. Survival benefit is uncertain; decision is individualized. Lippincott Journals

When to see a doctor immediately

• New or rapidly worsening eye pain, bulging, double vision, droopy eyelid, or any drop in vision.

• Fever or severe headache with one-sided nasal blockage or discharge, especially if you are immunocompromised or have diabetes.

• Numb face, trouble moving the eye, or confusion/drowsiness.
  These are emergencies — go to an emergency department with ENT and ophthalmology support.

What to eat — and what to avoid

1. Eat a balanced, protein-rich diet (eggs, fish/poultry, legumes, dairy if pasteurized) to help healing.

2. Plenty of cooked vegetables and peeled/washed fruits (if immunosuppressed, follow safe-handling rules from your team). CDC

3. Hydrate well (unless on fluid restriction) — protects kidneys, especially on amphotericin.

4. Avoid raw/undercooked meat, fish, eggs; avoid unpasteurized milk/juice. Leukemia & Lymphoma Society

5. Be cautious with salad bars/buffets during chemotherapy or high-risk periods. CDC

6. Avoid grapefruit, pomelo, Seville orange products unless your clinicians say it’s safe — potential azole interactions. Mayo Clinic

7. Limit alcohol — increases liver strain with azoles.

8. Avoid “immune booster” megadoses or unverified herbs — interactions are common. U.S. Food and Drug Administration

9. Discuss probiotics first if you are immunocompromised — rare bloodstream infections can occur. PMC

10. Work with a dietitian if appetite or taste is poor; early support prevents weight/muscle loss.

FAQs

1) Is orbital aspergillosis contagious?
No. You inhale spores from the environment; it does not spread person-to-person.

2) How fast can it damage vision?
Sometimes within hours to days in fulminant cases. Any vision change is an emergency.

3) What is the main treatment?
Antifungal drugs (often voriconazole or liposomal amphotericin B) plus surgery to remove infected tissue. Treatment continues at least 6–12 weeks and longer if needed. PMC

4) Do I always need surgery?
In invasive sinus/orbital disease, yes — debridement improves outcomes and provides tissue diagnosis. NCBI

5) Can local (retrobulbar) amphotericin injections save the eye?
They can help as an adjunct in selected patients when used with systemic therapy and surgery, but they are not a replacement and evidence is mostly observational. PMC

6) How long do scans stay abnormal?
CT/MRI can lag behind; doctors follow symptoms, labs, and serial imaging to decide duration. PMC

7) Why avoid grapefruit?
It can change the levels of many medicines by blocking CYP3A4 in the gut, potentially affecting azole antifungals and other drugs. U.S. Food and Drug Administration

8) Are echinocandins (like caspofungin) first-choice?
They are useful as salvage or in combination, but not routine first-line monotherapy for invasive aspergillosis. Medscape

9) Will I get better without surgery if I just take medicine?
In true invasive disease, outcomes are worse without debridement. Surgery is part of standard care. NCBI

10) Do steroids help the swelling?
No — in invasive aspergillosis, steroids generally worsen infection and are avoided unless there is another compelling indication. IDSA

11) How do doctors confirm it’s Aspergillus and not mucormycosis?
Tissue biopsy with special stains and culture; Aspergillus shows thin septate hyphae with acute-angle branching. Nature

12) What about “stem-cell drugs” to boost immunity?
There are no approved stem-cell drugs to treat this infection. Doctors sometimes use G-CSF/GM-CSF, IFN-γ, or granulocyte transfusions in selected cases. IDSA

13) How do doctors choose between voriconazole and amphotericin?
They weigh site of disease, other illnesses, liver/kidney function, drug interactions, and local experience. Isavuconazole and posaconazole are options when needed. NCBI

14) How will my team prevent a relapse later?
If you need future immunosuppression, they may use secondary prophylaxis and close monitoring. IDSA

15) What can I do right now?
Get urgent care for any red-flag symptoms, take medicines exactly as prescribed, keep all follow-up visits and lab checks, follow food safety and mold-avoidance tips, and ask about drug interactions before adding any new product. CDCU.S. Food and Drug Administration
