Bilateral Acute Depigmentation of the Iris (BADI)

Bilateral Acute Depigmentation of the Iris (BADI) is a rare eye condition where both irises suddenly lose their brown/blue/green color in patches or diffusely. The pigment that normally sits in the iris stroma (the front layer of the iris) breaks free and spreads into the front chamber of the eye. Doctors can see this pigment as tiny specks floating in the fluid or collecting on eye structures. Importantly, there is usually no iris “transillumination” (no light shining through holes in the iris on exam) and the pupil muscle still works. Many patients have redness, discomfort, and light sensitivity, and some notice that their eye color looks lighter. In many cases, vision stays good and the course is benign, though a small pressure rise can occur and needs monitoring.

BADI is an eye condition where both irises suddenly lose color (pigment) from the front stroma of the iris. Pigment sheds into the eye’s fluid, which can make the front of the eye look dusty under a slit lamp. Unlike a related condition called BAIT (bilateral acute iris transillumination), BADI typically does not show bright light “shine-through” holes when a doctor tests for transillumination, and the pupils usually still constrict and relax normally. Symptoms often include light sensitivity and mild redness; vision is often preserved. Many cases improve over time. oftalmoloji.org+2ScienceDirect+2

Doctors diagnose BADI by history and eye exam: sudden, bilateral, symmetrical stromal depigmentation, pigment in the front chamber, normal sphincter function, and no classic transillumination. It is considered rare, and has been described in case series and reviews since the late 2000s, with good long-term outcomes in many patients. National Organization for Rare Disorders+3ScienceDirect+3SAGE Journals+3

This pattern was first described in case series in the mid-2000s. PubMed+1

• BAIT (Bilateral Acute Iris Transillumination) is a related condition on the same spectrum but deeper: pigment is lost from the iris pigment epithelium, there are diffuse transillumination defects, and pupils may become large and poorly reactive; ocular pressure spikes are more frequent and can be severe. BADI, by contrast, originates in the stromal layer, has no transillumination and no sphincter paralysis; pressure tends to be lower and the course milder. EyeWiki+1

• Pigment dispersion syndrome (PDS) is a different entity: pigment rubs off the back of the iris from mechanical contact with the lens zonules, creating mid-peripheral transillumination defects, Krukenberg spindle on the cornea, and heavy angle pigmentation; it is usually chronic, not an abrupt bilateral event like BADI/BAIT. EyeWiki

• BADI can be mistaken for uveitis (eye inflammation), but in BADI the anterior chamber typically lacks inflammatory cells/KPs and lab work-ups are often unrevealing. PubMed

Types

There isn’t a formal staging system, but clinicians recognize a few patterns that help with recognition and follow-up:

1. Diffuse stromal depigmentation: a widespread, even lightening of the iris color affecting both eyes. PubMed

2. Geographic/patchy depigmentation: island-like pale patches with normal areas between. PubMed

3. Peripheral-predominant depigmentation with sparing near the pupil (a commonly noted feature in case descriptions). BioMed Central

4. Symmetric bilateral onset (the rule), with rare asymmetric presentations. EyeWiki

5. Acute phase (heavy pigment release, symptoms) vs recovery phase (pigment quiets; partial repigmentation sometimes occurs over years). EyeWiki

Causes and contributors

BADI’s exact cause is unknown. Research points to associations and triggers, and some come from the broader BADI–BAIT spectrum. Below are 20 factors that have been reported or proposed; think of them as possible contributors rather than proven causes for every patient:

1. Idiopathic onset: in many patients, no clear trigger is found. PubMed

2. Recent respiratory or viral illness (post-infectious immune response). EyeWiki

3. COVID-19 infection preceding BADI/BAIT-spectrum presentations in case reports. oftalmoloji.org

4. Systemic antibiotics temporal association (across the spectrum); strongest signal is for moxifloxacin in BAIT; BADI has also been reported after antimicrobials, though causality remains uncertain. oftalmoloji.org

5. Fluoroquinolones (e.g., moxifloxacin)—robustly linked to BAIT; clinicians avoid rechallenge in patients with prior BADI/BAIT. oftalmoloji.org+1

6. Clarithromycin—reported with BAIT-like presentations. EyeWiki

7. Intracameral moxifloxacin exposure during eye surgery—reported BAIT-like cases; relevance is mainly to BAIT but is part of the spectrum discussion. oftalmoloji.org

8. Traditional fumigation/chemical exposures—rare reports of BAIT after such exposures. EyeWiki

9. Insecticide exposure—a pediatric BADI case followed household insecticide spray; temporal, not proven causal. oftalmoloji.org

10. Pitcher-plant extract injections (migraine therapy) in a single case before BADI onset (association only). BioMed Central

11. Genetic or familial predisposition—siblings developing BADI simultaneously suggest susceptibility. EyeWiki

12. Immunogenetic background—HLA-B51/B27 noted in a share of BAIT cases with fluoroquinolone sensitivity, pointing to immune links (spectrum inference). EyeWiki

13. Autoimmune-like mechanism after infection or drug exposure (hypothesis from spectrum reviews). oftalmoloji.org

14. Young adult hormonal milieu—BADI/BAIT more often reported in women in their 30s-40s (association, not proof). EyeWiki

15. Light-mediated toxicity hypothesis with fluoroquinolones (mostly BAIT literature). EyeWiki

16. Geographic clustering—more reports from Middle Eastern/European cohorts (likely recognition bias). EyeWiki

17. Nonherpetic viral triggers—cases often lack herpetic markers and are PCR-negative for HSV/VZV in sampled eyes. PubMed

18. Post-illness steroid exposure—steroids are often tried for presumed uveitis before BADI is recognized; not a cause, but a confounder in history. BioMed Central

19. BAIT–BADI overlap in one patient—rare reports suggest shared pathways in some eyes (supports “spectrum” model). oftalmoloji.org

20. Environmental/occupational irritants—rare associations in case literature; again, temporal rather than proven causal. oftalmoloji.org

Take-home: BADI itself is usually idiopathic; many “causes” above are best viewed as potential triggers or risk contexts reported in case series, especially when considering the BADI–BAIT spectrum. oftalmoloji.org

10. Headache around the eyes (nonspecific). BioMed Central

11. Mild tenderness around the eyes (nonspecific). BioMed Central

12. No significant floaters (helps differentiate from intraocular inflammation). PubMed

13. No sustained vision loss in typical BADI (vision usually remains good). BioMed Central

14. No pupillary paralysis (pupils still react; distinguishes from BAIT). EyeWiki

15. Occasional pressure-related discomfort if IOP rises (less common than in BAIT). EyeWiki

Diagnostic tests

Doctors do not need all tests for every patient. They choose based on the exam. The goal is to confirm BADI and exclude look-alikes like BAIT, PDS, and viral uveitis.

A) Physical exam & history

1. Targeted history (recent infection, antibiotics, surgery, exposures): helps spot triggers and rule out uveitis causes. oftalmoloji.org

2. External inspection (color change/redness): the hallmark of BADI is bilateral color lightening with mild redness. PubMed

3. Visual acuity (Snellen): usually near normal in BADI; drop suggests another problem. BioMed Central

4. Pupil light testing: in BADI, pupils react normally; poor reaction suggests BAIT or other disease. EyeWiki

5. Photophobia assessment: common symptom that guides urgency and comfort care. PubMed

B) Manual/clinic-based slit-lamp and office tests

6. Slit-lamp biomicroscopy of the iris: shows stromal depigmentation without inflammatory keratic precipitates; confirms BADI pattern. PubMed

7. Anterior chamber check for pigment: tiny floating pigment particles point to active dispersion. PubMed

8. Gonioscopy: looks for pigment in the drainage angle; helps predict pressure issues and distinguish from PDS. PubMed+1

9. Applanation tonometry (IOP): pressure is often normal in BADI but can rise; must be monitored. EyeWiki

10. Corneal endothelium exam: may show a Krukenberg-type spindle of pigment; helps with differential against PDS. PubMed+1

11. Iris transillumination check (at the slit lamp): absent in BADI; diffuse positive in BAIT. EyeWiki

12. Dilated fundus exam: typically normal; rules out posterior inflammation or other causes of visual change. BioMed Central

C) Lab and pathological tests

13. Aqueous humor PCR for HSV/VZV/CMV (selected cases): often negative in BADI, but helps rule out viral uveitis when the picture is unclear. PubMed

14. Syphilis serology (e.g., treponemal tests): part of uveitis rule-out when diagnosis is uncertain. oftalmoloji.org

15. CBC, ESR/CRP: nonspecific screening if inflammation is suspected; typically normal in BADI. PubMed

16. HLA typing (B27, B51): not diagnostic for BADI, but may support an immune predisposition in spectrum cases exposed to fluoroquinolones. EyeWiki

17. Autoimmune panels (e.g., ANA): used when clinical clues suggest systemic inflammatory disease; usually unrevealing in straightforward BADI. PubMed

18. COVID-19 testing/history: helpful context if onset followed infection. oftalmoloji.org

D) Electrodiagnostic tests

19. Visual evoked potential (VEP): only if visual pathways are questioned (not routine in BADI). (Electrodiagnostics are generally normal in purely anterior segment disease.)

20. ERG or mfERG: considered when retinal complaints are out of proportion; usually normal in BADI.

E) Imaging tests

21. Anterior Segment Optical Coherence Tomography (AS-OCT): in BADI, shows iris stromal thinning/alteration without pigment epithelium loss; in BAIT, iris is thinned with transillumination defects and deeper pigment epithelium involvement. AS-OCT helps document structure and recovery. EyeWiki

22. Ultrasound biomicroscopy (UBM): assesses angle and iris if OCT images are limited; helps rule out other angle disorders. EyeWiki

23. Anterior segment photography: simple but valuable documentation to track repigmentation or progression. EyeWiki

24. Scheimpflug imaging: objective imaging of the anterior segment and pigment deposition; adjunctive, not required. EyeWiki

25. Iris transillumination photography: emphasizes the key difference—no transillumination in BADI vs diffuse in BAIT—useful for education and follow-up. EyeWiki

Non-pharmacological treatments

1) Education and reassurance
Description: BADI often alarms patients because the iris color looks different and light sensitivity starts suddenly. Simple, honest education calms fear and supports recovery. Explain that BADI is generally self-limited, vision is usually good, and many cases improve with time. Discuss how BADI differs from BAIT, and why doctors check eye pressure and pupils. Review warning signs (more pain, blurry vision, sudden halos, or headaches) that require prompt re-check. Encourage adherence to follow-ups because pigment can temporarily clog the drainage angle and raise pressure. Clarify that iris color may not fully return but function typically remains stable.
Purpose: Reduce anxiety, improve adherence, and catch complications early.
Mechanism: Understanding the disease improves self-care and timely reporting of problems, which indirectly improves outcomes. oftalmoloji.org+1

2) Photoprotection (sunglasses / hats)
Description: Bright light aggravates photophobia during the acute phase. Wearing quality sunglasses (UV-blocking) and a brimmed hat lowers light reaching the retina and reduces discomfort. Polarized lenses may help glare.
Purpose: Symptom relief and better daily function outdoors.
Mechanism: UV and visible light reduction lessens retinal and iris illumination, easing light sensitivity while the iris and anterior chamber calm down. oftalmoloji.org

3) Frequent follow-up with slit-lamp exams
Description: Scheduled checks allow the clinician to track pigment shedding, anterior chamber activity, and pupil reactions. Visits are most frequent early on, then spaced out as the eye quiets.
Purpose: Early detection of intraocular pressure (IOP) spikes or atypical signs.
Mechanism: Serial exam and tonometry find pressure rises or new inflammation before symptoms worsen. oftalmoloji.org

4) IOP monitoring and angle evaluation
Description: Pigment can reach the trabecular meshwork, temporarily obstructing outflow. Gonioscopy or angle imaging helps document pigment and angle status.
Purpose: Prevent glaucoma-like damage from unrecognized pressure spikes.
Mechanism: Measuring IOP and inspecting the angle detect outflow compromise early. oftalmoloji.org

5) Work/reading light control
Description: Use softer, indirect indoor lighting and screen filters during acute photophobia.
Purpose: Reduce strain and headaches from glare.
Mechanism: Lower luminance lessens pupil constriction demand and subjective discomfort. oftalmoloji.org

6) Dry-eye hygiene (environmental)
Description: Keep rooms humidified and avoid fans directly to the face. While not specific to BADI, less ocular surface dryness reduces additive irritation.
Purpose: Improve comfort while the anterior segment is reactive.
Mechanism: Better tear film stability decreases reflex photophobia and burning. EyeWiki

7) Contact lens holiday (if applicable)
Description: Temporarily pausing contact lens wear reduces mechanical irritation and limits confounders if drops are used.
Purpose: Improve comfort and reduce risk of surface complications.
Mechanism: Removing lens-related microtrauma allows the ocular surface to stabilize. EyeWiki

8) Blue-light management on screens
Description: Activate device night modes and use anti-glare settings during recovery.
Purpose: Ease photophobia during digital work.
Mechanism: Less short-wavelength light can reduce discomfort in light-sensitive eyes. EyeWiki

9) Sleep optimization
Description: Adequate sleep improves pain thresholds and light tolerance.
Purpose: Support systemic recovery after recent illness that might coincide with BADI onset.
Mechanism: Rest modulates inflammatory and neuro-sensory pathways. PubMed

10) Gentle hydration and nutrition
Description: Balanced fluids and meals during recovery support systemic wellness; avoid excessive caffeine that may worsen subjective eye discomfort.
Purpose: General supportive care.
Mechanism: Systemic stability can improve subjective tolerance to photophobia. PubMed

11) Avoid unnecessary mydriatic exposure
Description: Over-the-counter redness relievers sometimes contain sympathomimetics that can dilate pupils.
Purpose: Reduce extra glare and photophobia.
Mechanism: Limiting pharmacologic dilation keeps pupils responsive. EyeWiki

12) Stress reduction techniques
Description: Brief relaxation, breathing, or mindfulness sessions can lessen perceived pain and glare.
Purpose: Improve coping with acute symptoms.
Mechanism: Stress hormones modulate pain perception and autonomic balance. PubMed

13) Protective eyewear for dusty environments
Description: Use wraparound glasses in wind/dust to avoid surface irritation.
Purpose: Prevent additive irritation while eyes are sensitive.
Mechanism: Barrier protection reduces reflex tearing and photophobia triggers. EyeWiki

14) Avoid bright night driving early on
Description: Headlights and road glare can be hard to tolerate.
Purpose: Safety and comfort until light sensitivity improves.
Mechanism: Lower exposure to intense point-source glare. oftalmoloji.org

15) Document baseline iris photos
Description: Simple clinical photos help track color change over time.
Purpose: Objective comparison for counseling and research.
Mechanism: Visual records show stabilization or improvement. oftalmoloji.org

16) Consider occupational adjustments
Description: Brief schedule or task changes may help those in high-glare occupations.
Purpose: Maintain productivity without worsening symptoms.
Mechanism: Reducing light load supports symptom control. oftalmoloji.org

17) Gentle exercise as tolerated
Description: Non-straining activities can support overall health during recovery.
Purpose: Improve well-being without eye strain.
Mechanism: Moderate exercise supports autonomic balance and mood. PubMed

18) Avoid self-medicating with antibiotics
Description: BAIT has been associated with systemic fluoroquinolones in reports; while different from BADI, avoid unnecessary antibiotics.
Purpose: Steer clear of confounding risks.
Mechanism: Reduces exposure to drugs linked to BAIT, which is clinically distinct. EyeWiki

19) Structured symptom diary
Description: Track light sensitivity, pain, and any halos or blur day-to-day.
Purpose: Share actionable trends at follow-ups.
Mechanism: Patient-generated data guide pacing of therapy reduction. oftalmoloji.org

20) Family awareness
Description: Rare familial clustering is described; share warning signs with close contacts if they note similar symptoms.
Purpose: Encourage timely evaluation for others.
Mechanism: Early recognition reduces anxiety and delay. ScienceDirect

Immunity-booster / regenerative / stem-cell–related” drugs

There are no immune-booster or stem-cell drugs indicated for BADI. The items below explain concepts sometimes asked about, so you know why they’re not used.

1) Systemic corticosteroids (contextual)
100 words: Systemic steroids are powerful anti-inflammatories for severe uveitis, but BADI usually doesn’t need them. Risks outweigh benefits unless there is significant intraocular inflammation or another diagnosis. Dose and taper are specialist-directed only. Function: Immunosuppression. Mechanism: Broad cytokine inhibition. PubMed

2) Biologic DMARDs (contextual)
100 words: Biologics (e.g., anti-TNF) treat severe, systemic uveitis (like Behçet’s), not straightforward BADI. They are not indicated here unless another systemic inflammatory disease coexists. Function: Targeted immunomodulation. Mechanism: Blocks specific cytokines. PubMed

3) Autologous serum tears (supportive surface therapy)
100 words: Serum tears can help severe dry eye or surface disease; they are not for intraocular pigment dispersion but may comfort the ocular surface in complex cases. Dose: Specialist-compounded. Function: Epithelial support. Mechanism: Growth factors and vitamins mimic natural tears. EyeWiki

4) Platelet-rich plasma eye drops (experimental surface therapy)
100 words: PRP drops are studied for surface healing, not BADI itself. Consider only within specialist care if severe surface disease coexists. Function: Regenerative support. Mechanism: Platelet growth factors. EyeWiki

5) Stem-cell transplantation (not applicable)
100 words: Ocular stem-cell procedures target corneal or retinal disorders, not pigment dispersion of the iris stroma. They are not a treatment for BADI. Function: Tissue replacement. Mechanism: Cell-based regeneration. EyeWiki

6) Immunostimulant supplements (not recommended as “boosters”)
100 words: Non-specific “immune boosters” lack evidence for BADI and can interact with medicines. Focus on rest, nutrition, and clinician-guided care instead of unproven stimulants. Function: — Mechanism: — EyeWiki

Surgeries

1) Laser trabeculoplasty
Procedure/Why: If pigment causes sustained outflow resistance and medical therapy fails, laser to the drainage meshwork can enhance outflow and lower pressure. This is for pressure control, not pigment removal. SpringerLink

2) Trabeculectomy
Procedure/Why: Creates a new drainage pathway when medications and laser are inadequate. Reported primarily in BAIT-related refractory IOP, but the concept is similar if persistent IOP elevation complicates a pigment-dispersion event. EyeWiki

3) Aqueous shunt (tube) surgery
Procedure/Why: Places a small tube to drain fluid if other measures fail. Considered only for severe, persistent pressure problems. SpringerLink

4) Peripheral iridotomy
Procedure/Why: Generally not helpful because BADI is not a pupillary block disease; listed here to emphasize that it’s usually unnecessary unless another angle diagnosis exists. oftalmoloji.org

5) Cataract surgery (later, if needed)
Procedure/Why: Long steroid courses or age-related change can speed cataract; surgery treats the cataract but not BADI itself. FDA Access Data

Preventions

1. Avoid unnecessary systemic antibiotics, especially fluoroquinolones, unless clearly indicated and prescribed. This is to avoid BAIT-associated risk, not because antibiotics cause BADI. EyeWiki

2. Seek eye care promptly for sudden light sensitivity or color change to prevent complications. oftalmoloji.org

3. Use sunglasses outdoors to limit photophobia and glare stress during any future episodes. oftalmoloji.org

4. Keep regular eye checkups after respiratory or viral illnesses if you notice ocular symptoms. PubMed

5. Don’t self-medicate with steroid drops; improper use can raise pressure or hide infection. FDA Access Data

When to see a doctor

See an eye specialist immediately for sudden, bilateral light sensitivity, eye pain, redness, or a noticeable change in iris color. Seek urgent care for halos around lights, headache with nausea, or a rapid drop in vision—these can signal an IOP spike or another diagnosis. If you are already diagnosed with BADI, keep all follow-ups, because exams and pressure checks are essential during the first weeks. Return sooner if pain, glare, or blur worsen after starting or tapering drops. oftalmoloji.org+1

What to eat and what to avoid

Eat colorful vegetables (carotenoids), leafy greens, fish rich in omega-3s, nuts/seeds, whole grains, and drink adequate water—these patterns support general and ocular surface health. Limit ultra-processed foods, very salty meals (can worsen dryness), excessive caffeine (can aggravate perceived glare or headaches in some), and alcohol excess. Focus on balanced meals and steady hydration to feel better while your eyes are sensitive. Supplements are optional; prioritize food first and discuss any pills with your clinician. EyeWiki

Frequently Asked Questions (FAQ)

1) Is BADI the same as BAIT?
No. BADI affects the iris stroma and typically has no iris transillumination; BAIT affects the pigment epithelium, shows diffuse transillumination, and often causes atonic pupils. oftalmoloji.org

2) Will my eye color return to normal?
Color often improves over months, but some depigmentation can persist. Vision is usually preserved. SAGE Journals

3) Is BADI contagious?
No. It is not an infection, though some cases occur after respiratory illnesses. PubMed

4) Do I always need steroid drops?
Not always. Treatment is tailored to inflammation and symptoms. If used, they are monitored and tapered slowly. FDA Access Data

5) Can BADI raise eye pressure?
Yes, pigment can transiently clog the drainage angle. Doctors watch IOP closely and treat pressure if needed. oftalmoloji.org

6) Are prostaglandin drops safe in BADI?
They lower pressure well, but many clinicians avoid them during active anterior inflammation. Decisions are individualized once the eye is quiet. FDA Access Data

7) Do antibiotics help?
No. BADI is not bacterial. Avoid unnecessary antibiotics; some reports link fluoroquinolones with BAIT, which is different. EyeWiki

8) Could COVID-19 be related?
Some case series note BADI/BAIT-like presentations after COVID-19, but the relationship is not proven. PubMed

9) Will I need surgery?
Surgery is rare and only for persistent, drug-resistant high IOP (a complication), not for BADI itself. SpringerLink

10) Can I keep wearing contact lenses?
Pause during the acute phase to reduce irritation, then resume with your clinician’s advice. EyeWiki

11) Why are my pupils still reacting normally?
Because in BADI the iris sphincter usually remains functional, unlike BAIT. oftalmoloji.org

12) Is BADI lifelong?
Symptoms often improve over time; color changes may partially persist. Regular monitoring early on is key. SAGE Journals

13) Can children get BADI?
BADI is rare overall; most reports are in adults. Any child with sudden light sensitivity or iris color change should be examined urgently. oftalmoloji.org

14) Can I prevent BADI?
No proven prevention exists; prompt evaluation and supportive care minimize complications. oftalmoloji.org

15) What is the long-term outlook?
Generally favorable for vision with appropriate monitoring and management of inflammation and any IOP spikes. SAGE Journal
