Iris melanoma is a cancerous growth made from pigment cells (called melanocytes) in the iris, the colored ring at the front of your eye. These melanocytes normally give your eye its color. When a group of them turns abnormal and begins to grow on its own, invade nearby tissues, and has the potential to spread, we call it a melanoma.

Think of your iris as a thin, flexible curtain that opens and closes the pupil to control light. A melanoma can look like a dark or tan spot, a dome-shaped bump, or even a mostly colorless (amelanotic) nodule on that curtain. Some are circumscribed (with clear edges). Others are diffuse (spread out like a stain) and can creep into the eye’s drainage angle where the fluid leaves the eye. If the tumor blocks that drain, eye pressure rises—this is secondary glaucoma.

Iris melanoma is a solid, usually brown or tan lump or patch on the iris. It can be small and well-circumscribed (like a little dome) or flat and diffuse (spreading like paint). Sometimes it pushes or pulls the pupil off-center (called corectopia), rolls the iris edge outward (called ectropion uveae), or creeps into the drainage angle where the eye’s fluid leaves. If it blocks that drain, eye pressure rises and you can develop glaucoma. It may also bleed a little inside the eye (hyphema) or inflame the eye (uveitis). Most iris melanomas stay in the eye, but a few can spread elsewhere, especially to the liver. EyeWikiNature

Not every dark spot is cancer. Many iris spots are nevi (singular: nevus)—the eye’s version of a mole. A nevus is benign (non-cancer), tends to stay stable, and lacks worrisome features. A melanoma shows growth and aggressive behaviors (for example, feeder blood vessels on the surface, seeds of pigment in the front chamber, or distortion of the pupil). An eye specialist uses specific tools to tell them apart and may just watch a suspicious spot over time, because documented growth is one of the clearest signs of melanoma.

Why is this important? Because iris melanoma, although often slower-growing than melanomas deeper in the eye, can invade local tissues (iris, ciliary body, angle) and rarely spread to other parts of the body (especially lymph nodes, liver, lungs). Early recognition and proper follow-up reduce risk and guide the safest treatment.

Types of iris melanoma

Doctors describe iris melanoma in several helpful ways. These labels don’t change what you feel day-to-day, but they matter for diagnosis, monitoring, and treatment choice.

1) By growth pattern (what it looks like on the iris)

Circumscribed (nodular) melanoma
This is a compact bump with clear edges, like a small dome glued onto the iris surface. It may be tan, brown, dark, or (less often) pale. It can lift or distort the iris texture and may have tiny surface vessels feeding it. Easier to measure and photograph over time.
Diffuse melanoma (including ring melanoma)
This one spreads flat and wide along the iris or around the drainage angle, sometimes encircling the inside of the cornea like a ring. Because it’s flat and more sneaky, it’s harder to spot early and more likely to raise eye pressure by blocking the drain (angle), leading to glaucoma.

2) By cell appearance under the microscope (histology)

Spindle-cell melanoma
Tumor cells are long and thin (spindle shaped). These are often less aggressive than other cell types.
Epithelioid-cell melanoma
Cells look rounder and plumper with larger, more abnormal nuclei. Tends to behave more aggressively.
Mixed-cell melanoma
Contains both spindle and epithelioid cells. Behavior is in-between, depending on the mix.

3) By pigment

Pigmented melanoma
Looks brown, tan, or black because it makes melanin. Easier to see.
Amelanotic melanoma
Makes little or no pigment, so it can look pink, gray, or colorless. These can be trickier to diagnose because they don’t stand out by color.

4) By origin

Arising from a pre-existing iris nevus
A benign iris mole that later changes, gains new blood vessels, thickens, sheds pigment, or grows into melanoma.
De novo (from normal iris)
Appears without a known prior mole. It’s simply the first noticeable change.

5) By location and extent

Sectoral (one slice of the iris) versus multifocal (more than one spot).
With angle/ciliary body involvement when the tumor extends into the eye’s drain or the ciliary body (a structure behind the iris). This matters because it can affect pressure and treatment planning.

Causes and risk factors

No one “chooses” to get an iris melanoma. We talk about risk factors, not guaranteed causes. Having one or even several risk factors does not mean you will get it; it only nudges risk upward.

Ultraviolet (UV) light exposure to the eyes
Long-term sunlight (especially without sunglasses) may stress melanocytes. UV is strongly linked to skin melanoma and may also contribute to eye melanomas at the surface.
Light iris color (blue/green)
Lighter irises have less natural melanin shielding, so UV penetrates more. This doesn’t “cause” melanoma alone, but risk is a little higher.
Fair skin, red or blond hair
This body type often burns easily in sun and correlates with more melanomas overall.
Older age
Cell errors add up over time, so melanoma risk generally rises with age.
Pre-existing iris nevus (mole)
Most nevi stay harmless, but a small fraction can transform—especially if they grow, sprout feeder vessels, or seed pigment.
Ocular melanocytosis / Nevus of Ota
Extra pigment cells in the eye’s tissues can increase the odds of a uveal melanoma (iris is part of the uvea).
Family history of melanoma
Some families carry genes that make melanoma more likely. That’s a signal to get regular eye checks.
BAP1 tumor predisposition syndrome
A change in the BAP1 gene can raise risk for several cancers, including uveal melanoma.
Prior personal history of melanoma (skin or eye)
Having one melanoma may signal a predisposition, so doctors watch more closely.
Xeroderma pigmentosum (rare)
A genetic condition that limits DNA repair after UV damage, raising melanoma risk.
Immunosuppression (organ transplant medications, advanced HIV, chemotherapy)
A weakened immune system may be less able to clear abnormal cells early.
Intense unprotected UV from welding/arc lights
High-energy light exposure without proper shields stresses eye tissues.
Tanning beds
Deliver strong UV close to your body and eyes; protective eyewear is essential.
Geography with high UV index
Living/traveling where sunlight is very strong increases cumulative exposure.
Frequent outdoor activity without sunglasses
Hours add up; UV hits the eyes even when it’s cloudy.
Previous eye inflammation (uveitis)
Chronic inflammation can change the tissue environment, though the link is not strong—still worth mentioning.
Eye trauma
Trauma doesn’t “cause” cancer, but tissue repair after injury can unmask a lesion or accelerate evaluation that finds it.
Radiation exposure
Radiation can damage DNA. This is a rarer path but theoretically possible.
Multiple atypical skin moles (dysplastic nevus syndrome)
Signals a body that forms unusual melanocytic growths, so eye checks are smart.
Caucasian ancestry
Melanoma of the uvea is more common in people of European descent, likely tied to pigment biology.

Symptoms and signs

Many people feel fine and only learn about an iris lesion during a routine eye exam. Still, here are common ways it can present:

A new dark spot on the iris
Like a freckle or mole that wasn’t there before or is getting bigger.
A dome-shaped bump on the iris
Looks like the iris surface is raised at one point.
Change in eye color (heterochromia)
One iris becomes darker or lighter than the other, or one sector changes shade.
Pupil distortion (corectopia)
The black center (pupil) looks pulled toward the tumor or oddly shaped.
Ectropion uveae
The dark lining at the pupil edge rolls forward onto the iris surface—often a clue to a growing mass behind it.
New visible blood vessels on the iris
Tiny feeder vessels crawling over the spot suggest active growth.
Blurred vision
If the tumor distorts the iris or lens, or if pressure rises, vision can blur.
Glare and light sensitivity (photophobia)
Distortion of the pupil can cause stray light inside the eye.
Eye pain or ache
Usually due to high pressure (glaucoma) or inflammation.
Halos around lights / headaches
Another glaucoma-type symptom when pressure is up.
Red eye
From irritation or bleeding inside the eye.
Recurrent hyphema (blood in the front of the eye)
The tumor can bleed, causing sudden redness, pain, and blurred vision.
Shadow in side vision
If the mass or pressure changes affect peripheral vision.
Watery eye / tearing
Non-specific irritation response.
No symptoms at all
Many lesions are silent; that’s why regular dilated eye exams matter.

Diagnostic tests

Doctors don’t rely on one test. They combine what they see, what has changed over time, and what imaging shows. Biopsy is not always needed and can be avoided if the appearance is classic.

A) Physical exam

Targeted medical and ocular history
Your doctor asks about when you first noticed the spot, any growth, changes in vision, episodes of redness or bleeding, glare, family history, sun exposure, and past skin melanoma. This helps estimate risk and shape next tests.
External inspection with penlight
In a dark room, the clinician uses a simple light to spot surface color changes, bumps, or new vessels. It’s quick and safe, and guides more detailed imaging.
Pupil exam (light reflex and shape)
The doctor shines a light to see how your pupils react and whether the pupil is distorted or pulled toward a mass. Corectopia or poor reaction can be clues.
Eye pressure check (applanation tonometry)
A tiny probe gently touches the cornea (after numbing drops) to measure intraocular pressure. A higher reading suggests angle blockage or tumor-related glaucoma.

B) Manual tests

Visual acuity (Snellen chart)
You read letters on a chart. This tells whether your central vision is normal or reduced. A change may reflect pressure effects, lens distortion, or inflammation.
Confrontation visual fields
With one eye covered, you count fingers or see a moving target in the side vision. It screens for field loss that could occur if pressure is high or deeper structures are involved.
Color vision (Ishihara plates)
Measures color discrimination. Major color loss is less typical for iris lesions, but it’s a baseline and can reveal other problems.
Amsler grid
A small grid you look at to see if lines look wavy or missing. Mostly for macula issues, but it’s a simple way to track subjective visual changes over time.

C) Lab and pathological tests

Anterior chamber paracentesis (fluid cytology)
In select cases with repeated bleeding or pigment cells floating, a tiny amount of front-chamber fluid is sampled to look for tumor cells. It’s not routine, used when it will change management.
Fine-needle aspiration biopsy (FNAB) of the iris lesion
A very thin needle samples a small number of cells from the mass. Pathologists look under a microscope for melanoma cells. Because biopsy can seed cells or cause bleeding, it’s done only when absolutely needed.
Histopathology after surgical removal (iridectomy/iridocyclectomy)
If the lesion is removed, a full tissue exam shows cell type (spindle/epithelioid/mixed), growth pattern, mitotic rate, and invasion, which helps predict behavior.
Immunohistochemistry and tumor markers
Stains like HMB-45, Melan-A, S-100, Ki-67 (a proliferation marker), and BAP1 loss testing help confirm melanocytic origin and estimate aggressiveness. In some centers, molecular testing (e.g., GNAQ, GNA11, BAP1, SF3B1, EIF1AX changes) adds prognostic clues.

D) Electrodiagnostic tests

Electroretinography (ERG)
Measures electrical responses of your retina to light. Iris tumors don’t directly damage the retina, but if pressure is high or treatments affect the back of the eye, ERG gives an objective baseline of retinal health.
Visual evoked potential (VEP)
Records the brain’s response to visual stimuli via scalp sensors. It’s rarely required for iris melanoma but can document the visual pathway’s function if vision is unexpectedly reduced.

E) Imaging tests

Slit-lamp biomicroscopy with high-resolution photography
The core eye exam for the front of the eye. A slit-lamp is a microscope with a bright thin beam. It lets the doctor magnify and light-slice the iris to see edges, thickness, color, surface vessels, and tiny pigment “seeds.” Photos create a baseline so any growth can be measured precisely.
Gonioscopy (viewing the drainage angle)
A small mirrored contact lens shows the angle where fluid exits the eye. Doctors look for tumor extension into the angle, pigment dust, or blockage—key reasons why eye pressure may go up.
Ultrasound biomicroscopy (UBM)
A high-frequency ultrasound designed for the front of the eye. It measures tumor thickness, detects hidden parts behind the visible iris, and checks ciliary body involvement. Critical when the lesion is flat or amelanotic.
Anterior segment optical coherence tomography (AS-OCT)
A light-based scan (no radiation) that creates cross-section images of the iris and angle. Great for surface detail and edges; complements UBM (which penetrates deeper).
B-scan ocular ultrasound (standard)
Lower frequency than UBM, better for the back of the eye. Used to ensure there’s no posterior mass and to evaluate the ciliary body if visualization is poor.
MRI of the orbits (with contrast, when indicated)
Provides a 3D look at the eye and surrounding tissues, helpful when planning surgery or if doctors worry about extension beyond the iris. It avoids radiation and shows soft tissue well.

Non-pharmacological treatments

Key principle: Only two local treatments actually kill the tumor—precise eye surgery and precise eye radiation. Everything else below supports comfort, safety, or monitoring.

Active surveillance with strict follow-up
Purpose: Safe watch for small, uncertain lesions.
Mechanism: Serial photos, measurements, and scans detect true growth before intervention.
Patient-held photo/size diary
Purpose: Helps you spot change earlier.
Mechanism: Same lighting/angle photos make real growth easier to confirm.
Sun/UV and glare protection
Purpose: Comfort and general eye health (UV link to iris melanoma is not consistent).
Mechanism: Sunglasses/hat reduce light stress and photophobia. EyeWiki
Trauma avoidance & protective eyewear
Purpose: Prevent bleeding or tumor disturbance.
Mechanism: Safety glasses for sport/DIY work.
Plaque brachytherapy (iodine-125, palladium-103, ruthenium-106)
Purpose: Curative local radiation.
Mechanism: A custom “coin” with radioactive seeds sits on the eye wall over the tumor for a few days, delivering a high dose to the tumor and sparing other tissues; excellent local control in iris/iridociliary melanoma. PubMed CentralTermedia
Total anterior-segment plaque (for diffuse/multifocal cases)
Purpose: Treats wide tumor spread across the iris/angle.
Mechanism: Larger plaque covers the anterior segment; studies show good eye and vision preservation. PubMed Central
Proton beam therapy (sector or whole anterior segment)
Purpose: Curative local radiation, especially when a plaque won’t fit or tumor anatomy is tricky.
Mechanism: Charged particles stop at a precise depth (Bragg peak), allowing sharp dose shaping with high local control and eye retention. PubMed CentralPubMedRed Journal
Combined limited iridectomy + adjuvant plaque
Purpose: Remove bulk + sterilize margins when a clean surgical edge is uncertain.
Mechanism: Two-stage approach can yield excellent tumor control. IOVS
Specialist glaucoma care (non-drug strategies first)
Purpose: Slow optic-nerve damage.
Mechanism: Lifestyle/positioning tips, adherence tools, and careful target-pressure planning (medicines and, later, procedures if needed).
Low-vision aids (if vision drops)
Purpose: Maintain independence.
Mechanism: High-contrast lighting, magnifiers, device accessibility settings.
Dry-eye care (non-drug)
Purpose: Comfort with photosensitivity and after surface radiation.
Mechanism: Humidifiers, frequent breaks, preservative-free tears (technically a device/OTC).
Psychosocial counseling & support groups
Purpose: Reduce anxiety; improve adherence to follow-up.
Mechanism: Coping skills and education.
Occupational adjustments
Purpose: Reduce bright-light strain and impact risk.
Mechanism: Screen filters, scheduled breaks, task lighting.
Driving safety review
Purpose: Public and personal safety if vision/fields are affected.
Mechanism: Formal field testing and tailored advice.
Systemic cancer staging & surveillance plan
Purpose: Catch spread early to expand treatment options.
Mechanism: Timed liver imaging and blood tests. JNCCN
Nutrition and sleep hygiene
Purpose: Support immune health and treatment tolerance.
Mechanism: Balanced diet, regular sleep sustains resilience (not a tumor treatment).
Avoid unnecessary intraocular surgery until tumor is controlled
Purpose: Reduce theoretical seeding risk.
Mechanism: Defer elective procedures until after oncologic control.
Contact-lens caution
Purpose: Avoid rubbing/pressure over a raised lesion.
Mechanism: Fit review or temporary pause.
Education on warning signs
Purpose: Prompt reporting if things change.
Mechanism: Knowing when to call improves outcomes.
Second-opinion at an ocular oncology center
Purpose: Confirm plan and access specialized radiation/surgery options.
Mechanism: Multidisciplinary review.

Drug treatments

Medicines do not shrink iris melanoma itself (that’s surgery or radiation). Drugs mainly control complications (inflammation, pain, glaucoma). Systemic cancer drugs are used only if the disease spreads.

Prednisolone acetate 1% eye drops
Class: topical steroid. Dose: 1 drop 4×/day, then taper.
Purpose: Calm uveitis and surface inflammation.
Mechanism: Blocks inflammatory signals.
Side effects: Higher eye pressure, cataract risk, infection risk.
Atropine 1% drops (or cyclopentolate 1%)
Class: cycloplegic. Dose: 1 drop daily–BID (short courses).
Purpose: Pain relief from iris spasm; stabilizes blood–aqueous barrier.
Mechanism: Temporarily “paralyzes” focusing muscle; widens pupil.
Side effects: Light sensitivity, near-blur; avoid in angle-closure risk.
Timolol 0.25–0.5% drops
Class: beta-blocker. Dose: 1 drop BID.
Purpose: Lower IOP.
Mechanism: Slows fluid production.
Side effects: Low pulse, bronchospasm (avoid in asthma/COPD), fatigue.
Brimonidine 0.1–0.2% drops
Class: alpha-agonist. Dose: 1 drop TID (often BID in practice).
Purpose: Lower IOP.
Mechanism: Reduces production & increases outflow.
Side effects: Dry mouth, fatigue, allergic redness.
Dorzolamide 2% or Brinzolamide 1% drops
Class: carbonic anhydrase inhibitor. Dose: 1 drop TID (often BID).
Purpose: Lower IOP.
Mechanism: Reduces fluid production.
Side effects: Bitter taste, irritation; avoid if sulfa-allergic.
Latanoprost 0.005% at bedtime (or similar prostaglandin)
Class: prostaglandin analogue. Dose: QHS.
Purpose: Lower IOP (use cautiously if eye is inflamed).
Mechanism: Increases outflow.

Purpose: Rapid IOP lowering when drops aren’t enough.
Mechanism: Decreases fluid production.
Side effects: Tingling, fatigue, kidney stones, low potassium; avoid in sulfa allergy.
Pain control (Acetaminophen)
Class: analgesic. Dose: 500–1,000 mg every 6–8 h (max 3 g/day typical adult).
Purpose: Eye ache relief.
Mechanism: Central analgesia.
Side effects: Liver risk at high doses.
Immune checkpoint inhibitors (metastatic disease)
Examples & dosing: Nivolumab + ipilimumab (common combo, e.g., ipi 1 mg/kg + nivo 3 mg/kg every 3 weeks ×4, then nivo maintenance).
Purpose: Treat metastatic uveal melanoma (results are modest compared with skin melanoma).
Mechanism: Releases immune “brakes” (PD-1/CTLA-4).
Side effects: Immune-related inflammation of skin, gut, liver, lungs, thyroid.
Tebentafusp-tebn (KIMMTRAK®) — for HLA-A02:01-positive adults with unresectable or metastatic uveal melanoma*
Dosing: Step-up IV weekly (Week 1: 20 mcg; Week 2: 30 mcg; Week 3+: 68 mcg weekly).
Purpose: Improves survival in metastatic uveal melanoma.
Mechanism: A T-cell receptor bispecific that redirects T-cells to gp100 on melanoma cells.
Key precautions: Cytokine release syndrome highest in first 3 doses—hospital monitoring initially.
Side effects: Fever, low blood pressure, rash, liver test changes. FDA Access Data+1New England Journal of Medicine

Notes: Other targeted/MEK drugs have limited benefit in uveal melanoma; clinical trials are often the best option for systemic disease.

Dietary & supportive supplements

None of these treats melanoma. They may support overall eye/systemic health or treatment tolerance. Always check for interactions, especially if you’re on immunotherapy or glaucoma drops.

Vitamin D3 (1,000–2,000 IU/day): supports immune and bone health.
Omega-3 (EPA/DHA) (≈1 g/day): general anti-inflammatory heart/brain support; can aid dry eye.
Lutein (10 mg/day) & Zeaxanthin (2 mg/day): macular pigment support; antioxidant for the retina.
Vitamin C (500 mg/day): antioxidant; avoid mega-doses pre-op.
Vitamin E (≤200 IU/day): antioxidant; high doses raise bleeding risk.
Zinc (10–20 mg/day): cofactor in antioxidant enzymes; excess upsets copper balance.
Selenium (100–200 mcg/day): antioxidant enzyme support; avoid excess.
CoQ10 (100–200 mg/day): mitochondrial support; may help fatigue.
Magnesium glycinate (200–400 mg HS): sleep/muscle relaxation; keep bowels in check.
Probiotic (per label): gut comfort during systemic therapy; pick reputable brands.
Turmeric/Curcumin (≈500 mg/day): anti-inflammatory; may interact with drugs—ask your team.
Green tea extract (EGCG) (standardized dose): antioxidant; limit if liver enzymes rise.
Milk thistle (silymarin) (per label): popular for liver support; evidence is mixed—doctor approval needed.
Melatonin (1–3 mg HS): sleep aid; discuss if on immunotherapy.
AREDS2-style multinutrient (macular-health formula): optional for general ocular antioxidant coverage (not a melanoma treatment).

Regenerative” approaches

In iris/uveal melanoma, true “regenerative” or stem-cell drugs are not standard care. Below are immune-based or cell-based strategies used or studied for metastatic disease. Many remain clinical-trial territory.

Tebentafusp (TCR-bispecific) — described above; standard for eligible metastatic cases. FDA Access Data
Nivolumab + Ipilimumab (PD-1 + CTLA-4) — standard combo; responses are less frequent than in skin melanoma.
Pembrolizumab (PD-1) — single-agent option; modest activity.
Tumor-infiltrating lymphocyte (TIL) therapy — personalized adoptive T-cell therapy; investigational for uveal melanoma.
Dendritic-cell vaccines — experimental immune priming against melanoma antigens.
Engineered T-cell therapies (e.g., TCR/CAR-T concepts) — early-phase research for uveal targets.

Surgeries

Sector Iridectomy
What: Remove the tumor with a rim of healthy iris.
Why: For small, well-placed nodular tumors without deep extension—goal is cure + iris shape preservation.
Iridocyclectomy
What: Remove a sector of iris and adjacent ciliary body if the tumor extends backward.
Why: Achieve full removal when ciliary body is involved.
Excisional biopsy (when diagnosis is uncertain)
What: Carefully lift and remove a small lesion for definitive pathology.
Why: Avoid over- or under-treating look-alikes.
Glaucoma tube shunt (after tumor control)
What: A tiny tube diverts fluid to lower pressure.
Why: For radiation-or tumor-related glaucoma that resists drops; typically placed after the melanoma is controlled to reduce seeding risk.
Enucleation (eye removal)
What: Remove the eye.
Why: Last resort—very large, recurrent, or painful eyes when vision can’t be saved; modern care aims to avoid this.

Many diffuse or awkwardly located tumors are best treated with plaque or proton radiation instead of cutting. PubMed Central+1

Prevention tips

You cannot fully prevent iris melanoma. These steps focus on general eye safety, early detection, and risk reduction.

Routine comprehensive eye exams (every 1–2 years; sooner if you have an iris spot).
Baseline iris photos if you have a nevus; repeat if anything changes.
Report growth, shape change, bleeding, or new symptoms promptly.
Wear UV-blocking sunglasses and a brimmed hat (comfort & general eye protection; UV link to iris melanoma is not consistent). EyeWiki
Avoid tanning beds (bad for skin, eyes, and eyelids).
Protect your eyes at work and sport (safety glasses).
Don’t rub or press on a raised iris lesion.
Keep systemic diseases controlled (diabetes, hypertension) to support overall ocular health.
If you’re immunosuppressed, keep tight follow-up schedules.
Know your family history and seek specialist advice if uveal melanoma runs in the family.

When to see a doctor

Urgently (same day / within 24–48 hours): sudden eye pain, marked vision drop, visible blood in the eye, very high eye pressure symptoms (rainbow halos, nausea), or a rapid change in an iris spot.
Soon (within weeks): a new iris spot, slow growth of a known spot, pupil shape change, new light sensitivity, or family history with any suspicious change.

What to eat (and what to avoid)

Food won’t treat a tumor, but good nutrition supports healing and resilience.

Good to eat

Colorful fruits/veggies (berries, citrus, peppers).
Leafy greens (spinach, kale) for carotenoids.
Oily fish (salmon, sardines) 2×/week for omega-3s.
Nuts/seeds (walnuts, chia, flax).
Whole grains (oats, brown rice).
Lean proteins (beans, lentils, poultry).
Olive oil and other unsaturated fats.
Hydration first (water, herbal teas).
Fermented foods (yogurt, kefir) for gut health.
Spices like ginger/garlic for flavor without excess salt.

Best to limit/avoid

Heavy alcohol (especially if on meds that affect the liver).
Ultra-processed foods and sugary drinks.
Excess salt (blood pressure).
Charred/smoked meats frequently.
Mega-dose antioxidants right around radiation/surgery (ask your team).
Grapefruit products if on medications with known interactions.
High-dose green tea extracts if your liver enzymes are up.
Unverified supplements from non-reputable sources.
Stimulant/herbal blends that spike pressure or heart rate.
Anything your care team specifically flags as an interaction.

Frequently asked questions (with plain answers)

Is an iris freckle the same as melanoma?
No. Freckles/nevi are common and benign; melanoma shows growth or concerning features and needs specialist evaluation. AAO
How dangerous is iris melanoma compared with other uveal melanomas?
On average, iris melanoma tends to be more indolent with lower metastasis rates than choroidal/ciliary body melanomas—but it still can spread, so proper treatment and follow-up matter. Retina Today
How do doctors tell it’s melanoma and not something else?
By slit-lamp exam, gonioscopy, and imaging (UBM/AS-OCT). If still unclear, a biopsy may be done. PubMedPubMed Central
Will I lose my eye?
Modern care aims to preserve the eye. Plaque or proton radiation and conservative surgery control most tumors while keeping useful vision. Enucleation is now uncommon and reserved for extreme cases. PubMed Central+1
What are the most common complications of treatment?
Cataract, dry eye/irritation, and sometimes glaucoma—all treatable. Proton/plaques aim to target the tumor and spare other structures. PubMed Central
Will I get glaucoma?
About a third present with or develop glaucoma due to angle invasion or inflammation; careful pressure control is part of care. EyeWiki
Do I need systemic scans?
Your team usually sets a liver-focused surveillance plan (ultrasound or MRI + labs) because the liver is the most common site if spread happens. JNCCN
Are there pills that cure iris melanoma?
No. Local treatments (surgery/radiation) cure the eye tumor. Pills/infusions are used only if it spreads.
If it spreads, what’s new in treatment?
For eligible patients (HLA-A*02:01), tebentafusp is now a standard option and has improved survival; immune checkpoint combinations are also used, though responses are less frequent than in skin melanoma. FDA Access DataNew England Journal of Medicine
Can I wear contact lenses?
Often yes, but fit must be reviewed; avoid pressure/rubbing on a raised lesion.
Can I have cataract surgery later?
Yes—frequently after tumor control. Timing is coordinated with your ocular oncologist.
Will radiation make me blind?
For iris-targeted plaque/proton therapy, the retina is largely spared; the main risks are cataract and surface irritation, which are manageable. PubMed Central
Is sunlight the cause?
For iris melanoma, a clear UV link hasn’t been proven; still, UV protection is smart for general eye health. EyeWiki
How often will I be seen after treatment?
Commonly every 3–6 months initially, then yearly, alongside liver surveillance—your schedule is individualized. JNCCN
Should I get a second opinion?
Absolutely reasonable—ocular oncology centers offer specialized imaging and radiation planning.
