Frequently asked questions (FAQs)

Thygeson Superficial Punctate Keratitis—often shortened to TSPK—is a long-lasting, on-and-off inflammation of the front, clear window of the eye called the cornea. In TSPK, small, slightly raised, gray-white spots form in the top layer of the cornea (the epithelium). These spots are scattered, usually sit near the center of the cornea, and irritate the surface. During a “flare,” people feel strong light sensitivity, a gritty or sandy feeling, tearing, and blurry or fluctuating vision. The condition typically affects both eyes, gets better and worse in cycles, and can last for months or even years with quiet periods in between. It does not usually scar the cornea, and long-term vision is usually preserved, but the symptoms can be very uncomfortable while the spots are active. Doctors diagnose it by looking at the cornea under a slit-lamp microscope and by ruling out infections like herpes or adenovirus. The exact cause is not fully known, but research suggests an immune-related problem, and some patients carry certain HLA (immune system) types more often than the general population. Treatment focuses on soothing the surface, calming the immune inflammation, and preventing steroid side effects when drops are needed. EyeWikiVagelos CollegeBioMed Central

Thygeson Superficial Punctate Keratitis (TSPK) is a long name for a surface problem of the cornea—the clear “window” at the front of your eye. In TSPK, tiny, shallow spots appear on the outermost corneal layer (the epithelium). These spots are not ulcers and they do not go deep. They are like little rough patches on a smooth glass surface. The condition usually affects both eyes, but one eye can bother you more at a time. It tends to come and go in “flares,” with quiet periods in between. During flares, your eyes can feel gritty, watery, light-sensitive, and blurry, but many people still have a healthy cornea between episodes. TSPK does not usually scar the cornea, and most people keep good vision long-term. Doctors believe it is an immune-mediated condition (your body’s defense system becomes over-reactive on the eye surface), not an infection. That is why soothing care and anti-inflammatory treatment help most.

How TSPK behaves and why it matters

TSPK is “benign” in the sense that it rarely leaves scars or causes permanent damage, but it can make day-to-day life hard because of light sensitivity, foreign-body sensation, and fluctuating blur. Flares may last weeks to months and then fade, only to return later. Many people notice their symptoms improve quickly with mild steroid drops, but frequent or long steroid use can raise eye pressure or cause cataract if not monitored. Because of that, doctors often combine artificial tears with steroid-sparing immune drops such as cyclosporine or tacrolimus to reduce relapses and limit steroid exposure. WebEyePMC+1Ajo

Types

Because there is no single official “staging” system used everywhere, it helps to sort TSPK by patterns doctors actually see. These groupings are practical, not rigid.

a) By severity of surface spots

Mild: Few small, coarse epithelial spots; mild irritation and light sensitivity; minimal blur.
Moderate: More spots clustered near the center; clear light sensitivity; tearing and variable blur.
Severe: Many spots, often central; strong photophobia; trouble with reading or screens; may need protective contact lens or stronger anti-inflammatory drops.
(Clinically, the lesions are coarse, discrete, and often central; conjunctiva is usually quiet.) Vagelos College

b) By course over time

Episodic-relapsing: Distinct flares that settle, then recur.
Chronic-persistent: Symptoms never fully clear for long; low-grade activity with frequent spikes.
(Both patterns are well-described; some patients report many years of up-and-down disease.) EyeWiki

c) By response to medicine

Steroid-responsive: Rapid relief with mild topical steroid; relapse when tapering is too fast.
Steroid-dependent: Flares recur whenever steroids stop; needs steroid-sparing agents (cyclosporine/tacrolimus) to maintain control. PMC+1Ajo

d) By age at first diagnosis

Pediatric onset: Children can be affected; immune mechanisms are suspected; management aims to minimize steroid burden.
Adult onset: The more common presentation; same principles apply. BioMed Central

e) By laterality

Bilateral (most common): Both eyes involved, often asymmetrically.
Unilateral (less common or early phase): One eye may flare first, with the other eye joining later. Vagelos College

Causes

No single proven cause explains every case of TSPK. The best way to think about “causes” is as drivers, triggers, and associations that can help the disease appear or flare. Each item below is explained in plain English; together they reflect current evidence and common clinical observations.

Immune-mediated surface inflammation. The strongest thread is an overactive immune response in the corneal epithelium, which creates the small elevated spots without a living germ causing them. BioMed Central
Genetic immune background (HLA-DR3 and related types). Some patients carry HLA patterns like DR3 more often than the general population, hinting that their immune systems are primed to overreact at the corneal surface. This is an association, not a destiny. EyeWikiBioMed Central
Post-viral immune “echo.” After a past viral keratitis (such as herpes or adenovirus), the surface immune system may remain irritable, leading to non-infectious relapses that look like TSPK. The active spots in TSPK itself are usually not infectious. WebEye
Dry eye and unstable tear film. A poor tear coating stresses the epithelium and can trigger or worsen surface irritation that looks and feels like a flare. (Dry eye is common and can coexist with TSPK.)
Meibomian gland dysfunction/blepharitis. Oil gland problems in the lids destabilize tears and increase surface friction, provoking symptoms and staining.
Contact lens friction or environment. Regular wear is not a known “cause,” but mechanical friction or overwear can aggravate a sensitive surface; bandage lenses, however, are sometimes used therapeutically to protect the surface during a bad flare. PMC
Ultraviolet (UV) and bright light. Strong light can trigger photophobia and drive people to rub; cumulative UV exposure still irritates a reactive surface.
Dust, wind, smoke, and air pollution. These irritants dry and inflame the epithelium, encouraging micro-injury and symptoms.
Allergy and atopy. Some patients with allergic eye disease have a “hyper-reactive” surface; while TSPK is not allergic keratoconjunctivitis, atopy can worsen comfort and tear stability. StatPearls
Systemic immune activation. Any body-wide immune flare (infection, strong inflammatory illness) can amplify ocular surface sensitivity.
Hormonal and life-stage factors. Tear composition and immune tone change with age, pregnancy, and menopause, which may modulate surface reactivity.
Screen time and reduced blinking. Long, concentrated visual tasks reduce blink rate and dry the corneal surface, making flares more noticeable.
Cold, dry air-conditioning or airplane cabins. Very dry air worsens tear evaporation and surface friction.
Topical medication toxicity. Frequent use of preserved drops (especially benzalkonium chloride) can irritate epithelium and mimic or magnify flares.
Eye rubbing. Rubbing increases mechanical trauma to a fragile epithelium and should be discouraged.
Post-surgical surface stress. Although not a routine cause, any corneal procedure that alters the epithelium–Bowman’s interface may leave the surface more reactive for a time. In vivo confocal studies show sub-basal nerve and anterior stromal changes in TSPK. PubMed
Cold or flu season overlap. Flares sometimes cluster with seasonal viral illnesses, possibly via immune crosstalk, even when no live virus is found on the cornea. WebEye
Psychological stress and poor sleep. Stress hormones and poor sleep quality can worsen pain sensitivity and immune noise, which many patients notice at the surface of the eye.
Rare disease associations. A recent report described TSPK occurring with celiac disease, suggesting shared HLA patterns might link them in some patients; this is rare and needs more study. PubMedCureus
Idiopathic nature. Even after a careful work-up, many cases remain “unexplained,” which is why TSPK is still considered idiopathic and diagnosed mainly by its typical look, symptoms, and course. WebEye

Symptoms

Photophobia (light sensitivity): Bright light hurts or forces the eyes to squint because the irritated surface is overloaded by light. Vagelos College
Foreign-body sensation: The eye feels gritty or sandy, as if something is stuck, because the raised spots disturb the smoothness of the cornea. Vagelos College
Tearing: Reflex tears increase to wash the irritated surface, but they often do not relieve the scratchy feeling.
Redness: The eyes can look pink or red during a flare, though the conjunctiva may be surprisingly quiet compared with how uncomfortable the eye feels. Vagelos College
Blurred or fluctuating vision: The cornea must be perfectly smooth to focus clearly; the little bumps scatter light and blur vision.
Halos and glare: Lights at night can look smeared or haloed because of surface scatter.
Stinging or burning: The inflamed surface fires pain signals, especially with wind or smoke.
Dryness feeling: Even with tearing, the surface can feel dry because tears break up too quickly over the rough spots.
Eye fatigue: Reading or screen work becomes tiring because the eye struggles to keep the optical surface smooth.
Headache around the eyes: Squinting from light and eye strain can trigger frontal headaches.
Trouble with small print: Micro-fluctuations in focus make fine tasks harder.
Contact lens intolerance during flares: Lenses may feel scratchy because they ride over the bumps; bandage lenses are sometimes used by the doctor for protection under supervision. PMC
Watery discharge but not thick pus: TSPK is not a typical bacterial infection, so discharge is usually watery rather than sticky.
Better and worse days: Symptoms wax and wane, often improving with rest or treatment and worsening with triggers like wind or screen marathons. EyeWiki
Both eyes involved, often unevenly: One eye may feel worse, but both are usually affected over time. Vagelos College

Diagnostic tests

A) Physical examination at the slit lamp

1) Visual acuity testing (Snellen chart). Measures how clearly you see. In TSPK, vision may drop during flares and improve between episodes.
2) External exam of lids and lashes. Checks for lid margin disease, blepharitis, and debris that could aggravate the surface.
3) Conjunctival assessment. Looks for allergic papillae or follicles; in TSPK the conjunctiva often looks calmer than expected. Vagelos College
4) Slit-lamp biomicroscopy of the cornea. The doctor sees coarse, discrete, slightly elevated gray-white epithelial spots, often central, which is the hallmark of TSPK. Vagelos College
5) Fluorescein staining. A yellow dye highlights surface defects under blue light. TSPK spots may stain faintly or irregularly; the pattern helps distinguish TSPK from herpes dendrites or simple dry-eye dots. EyeWiki
6) Rose bengal or lissamine green staining. These dyes can better outline damaged or unprotected epithelial cells and mucus-deficient areas, adding clues that the process is non-infectious. EyeWiki

B) Office “manual” surface tests

7) Tear film break-up time (TBUT). After fluorescein, the doctor measures how fast the tear film breaks. Fast break-up means poor tear stability, which aggravates symptoms and explains fluctuating blur.
8) Schirmer test (tear quantity). A tiny strip of paper at the lid margin measures tear volume to identify co-existing dry eye.
9) Corneal sensitivity (esthesiometry). A thin filament gently touches the cornea to check nerve sensitivity; normal sensitivity helps argue against active herpes keratitis.
10) Lid eversion to inspect the tarsal surface. Turning the upper lid checks for large papillae that would suggest allergic disease rather than TSPK. StatPearls

C) Laboratory and pathological tests (used selectively to exclude mimics)

11) Herpes simplex virus (HSV) PCR or culture from the corneal surface (if the picture is atypical). This test detects viral DNA or live virus; negative results in a dendrite-like lesion support a non-infectious diagnosis. WebEye
12) Adenovirus rapid antigen/PCR (if acute red eye and follicles raise suspicion). Positive results point to epidemic keratoconjunctivitis rather than TSPK.
13) Bacterial and fungal cultures (when ulcers or infiltrates are present). These are rarely needed in classic TSPK but are vital when infection is possible.
14) Impression cytology. A gentle cellulose paper lifts superficial cells to check for goblet cell loss or metaplasia; this helps characterize surface health, especially in chronic disease.
15) HLA typing in research settings. Sometimes used to explore immune background (e.g., HLA-DR3) in studies rather than for routine diagnosis. BioMed Central

D) Electrodiagnostic tests (usually not required, but noted for completeness)

16) Visual evoked potential (VEP). Measures brain responses to visual patterns; generally normal in TSPK and reserved for unexplained visual loss.
17) Electroretinography (ERG). Tests retinal function; expected to be normal because TSPK is a corneal surface disorder.
18) Electro-oculography (EOG). Assesses retinal pigment epithelium; like ERG, not a routine TSPK test.
(These are listed to be thorough; in typical TSPK they are unnecessary.)

E) Imaging tests

19) In vivo confocal microscopy. A special microscope images corneal layers at very high resolution. Studies in TSPK show abnormalities in subepithelial nerves, Bowman’s layer, and anterior stroma that relate to disease duration, supporting an immune-surface disturbance rather than an active infection. PubMed
20) Anterior segment OCT (AS-OCT). Non-contact light imaging can reveal hyper-reflective epithelial lesions that match the clinical spots and help document change over time. IOVS

Non-pharmacological treatments (therapies and others)

(Each item includes Description → Purpose → Mechanism, in plain English.)

Frequent lubricating eye drops (preservative-free artificial tears)
Description: Use single-use vials several times a day during flares and as needed between flares.
Purpose: Soothe irritation, reduce burning, and smooth the eye surface.
Mechanism: Adds moisture and creates a protective layer over the cornea so the rough spots cause less friction when you blink.
Lubricating gel or ointment at bedtime
Description: A thicker gel or ointment before sleep.
Purpose: Night comfort and morning relief.
Mechanism: Stays longer on the eye, reducing overnight dryness and early-morning scratchy feeling.
Cold compresses
Description: Clean cold pack or chilled eye mask for 5–10 minutes.
Purpose: Calm inflammation and light sensitivity.
Mechanism: Cold reduces surface nerve activity and swelling, easing discomfort.
Sunglasses and brimmed hats outdoors
Description: Wear high-quality UV-blocking sunglasses.
Purpose: Cut glare and photophobia.
Mechanism: Less light entering the eye means the rough surface scatters less light, so you feel more comfortable.
Humidifier and environment control
Description: Use a room humidifier, avoid direct AC or fan air to the face.
Purpose: Reduce dryness triggers.
Mechanism: Moist air slows tear evaporation, keeping the surface smoother.
Screen breaks (20-20-20 rule)
Description: Every 20 minutes, look 20 feet away for 20 seconds.
Purpose: Prevent “staring” dryness with digital use.
Mechanism: Reminds you to blink fully and refresh tears.
Eyelid hygiene
Description: Warm compress + gentle lid massage + diluted lid cleanser if advised.
Purpose: Improve tear quality and comfort.
Mechanism: Healthier oil glands reduce tear evaporation and stabilize the tear film over the rough cornea.
Protective eyewear in dusty/windy settings
Description: Wrap-around glasses or goggles when needed.
Purpose: Prevent irritation from particles and wind.
Mechanism: Shields the ocular surface from drying air and irritants.
Allergen reduction (if you have allergies)
Description: Keep windows closed in high-pollen seasons, rinse hair/face after outdoors, use HEPA filter if helpful.
Purpose: Quiet down background eye inflammation.
Mechanism: Fewer allergens means fewer inflammatory signals on the eye surface.
Contact lens holiday during flares
Description: Pause contact lenses when symptoms flare.
Purpose: Reduce rubbing and friction.
Mechanism: Without a lens, the epithelium can settle and heal more comfortably.
Bandage contact lens (in-office fitting)
Description: A soft, medical contact lens placed by your eye doctor.
Purpose: Short-term protection and comfort in tougher flares.
Mechanism: Acts like a shield so the eyelid slides over the lens rather than the rough cornea.
Scleral lens (specialty fit)
Description: A large rigid lens that vaults over the cornea and holds fluid.
Purpose: For recurrent or stubborn discomfort and glare.
Mechanism: Maintains a pool of tears over the cornea, creating a new smooth optical surface.
Workstation ergonomics
Description: Place screen slightly below eye level; keep it at arm’s length; adjust brightness.
Purpose: Reduce squinting and dryness at work.
Mechanism: Encourages natural blinking and reduces strain that worsens irritation.
Hydration and regular blinking habit
Description: Drink water through the day; practice gentle, full blinks.
Purpose: Maintain a healthy tear layer.
Mechanism: Water supports tear volume; full blinks spread tears evenly.
Smoking cessation and smoke avoidance
Description: Avoid cigarette smoke and smoky rooms.
Purpose: Decrease eye surface irritation.
Mechanism: Smoke contains irritants that inflame the epithelium and destabilize tears.
Cool artificial tear “challenge”
Description: Chill preservative-free vials (not freezing) before use.
Purpose: Extra soothing during flares.
Mechanism: Cool temperature adds mild numbing and anti-inflammatory effect.
Nighttime eye shield or moisture chamber goggles
Description: Lightweight goggles for sleep in very dry rooms.
Purpose: Prevent overnight drying.
Mechanism: Traps humidity around eyes so the surface does not dry out.
Manage systemic triggers (sleep, stress, illness)
Description: Regular sleep, stress-reduction (breathing, mindfulness), treat colds/allergies.
Purpose: Lower flare frequency or intensity.
Mechanism: Calmer immune system → fewer inflammatory surges on the cornea.
Education and flare action plan
Description: Know early signs and steps (tears, cold compress, sunglasses, doctor if needed).
Purpose: Quicker control of symptoms.
Mechanism: Early, consistent steps calm the surface before inflammation escalates.
Follow-up schedule even when quiet
Description: Periodic checks, especially if you use steroid drops at times.
Purpose: Monitor pressure and surface health.
Mechanism: Early detection of treatment side effects and fine-tuning of prevention.

Drug treatments

Always use medicines under an eye doctor’s guidance.

Low-potency topical corticosteroid (e.g., fluorometholone 0.1%, “FML”)
Class: Corticosteroid anti-inflammatory.
Typical dosage/time: 2–4×/day during a flare, then taper over 2–4 weeks; lowest effective dose for the shortest time.
Purpose: Rapid relief of inflammation, light sensitivity, and blur.
Mechanism: Dials down immune activity on the corneal surface.
Key side effects/risks: Can raise eye pressure or cause cataract with overuse; infection masking. Requires monitoring.
Loteprednol etabonate 0.2–0.5%
Class: “Soft” corticosteroid.
Dosage/time: 2–4×/day during flare; taper.
Purpose: Similar to FML with potentially lower risk of eye-pressure rise in many patients.
Mechanism: Local anti-inflammatory action with rapid inactivation.
Side effects: Possible pressure rise, delayed healing, rare infection masking.
Topical cyclosporine A 0.05–0.1%
Class: Calcineurin inhibitor (immunomodulator).
Dosage/time: 2×/day; onset of benefit in several weeks; maintenance for flare prevention.
Purpose: Steroid-sparing control for recurrent TSPK.
Mechanism: Calms T-cell activity on the ocular surface.
Side effects: Temporary sting/burn; rare redness. No steroid pressure risk.
Topical tacrolimus 0.02–0.1% (drop or ointment; off-label in many regions)
Class: Calcineurin inhibitor.
Dosage/time: Usually 1–2×/day; often as night ointment.
Purpose: Alternative steroid-sparing controller.
Mechanism: Similar to cyclosporine; reduces immune signaling in epithelium.
Side effects: Stinging; rare irritation; monitor with your doctor.
Lifitegrast 5% (where available; off-label for TSPK)
Class: LFA-1 antagonist (anti-inflammatory).
Dosage/time: 2×/day; benefits in weeks.
Purpose: Additional steroid-sparing option when dryness-inflammation mix is strong.
Mechanism: Blocks inflammatory cell adhesion, reducing surface inflammation.

Hypertonic saline 5% drops/ointment (for morning blur from epithelial edema)
Class: Hyperosmotic.
Dosage/time: Drops in daytime; ointment at night as advised.
Purpose: Improve morning clarity if swelling contributes to blur.
Mechanism: Draws extra fluid out of the corneal epithelium.
Side effects: Temporary sting; not a core anti-inflammatory.
Topical antihistamine/mast-cell stabilizer (e.g., olopatadine, ketotifen)
Class: Anti-allergy.
Dosage/time: 1–2×/day during allergy seasons.
Purpose: Treat co-existing allergies that amplify surface inflammation.
Mechanism: Blocks histamine and stabilizes mast cells.
Side effects: Mild burn; dryness in a few.
Short course of topical NSAID (select cases only, with caution)
Class: Non-steroidal anti-inflammatory.
Dosage/time: Brief, low-frequency course if doctor feels helpful for photophobia; many clinicians avoid routine use on corneal epithelium.
Purpose: Light sensitivity relief.
Mechanism: Inhibits prostaglandins.
Side effects: Potential delayed healing; not for chronic use.
Antibiotic drops (only if epithelial breakdown + infection risk)
Class: Topical antibiotic.
Dosage/time: As directed for short prophylaxis if the surface is compromised.
Purpose: Prevent infection in rare cases with epithelial defects or bandage lens use.
Mechanism: Kills bacteria.
Side effects: Irritation, allergy; unnecessary in typical, intact-epithelium TSPK.
IOP-lowering drops (only if steroid causes pressure rise)
Class: Varies (beta-blocker, alpha-agonist, CAI, etc.).
Dosage/time: As prescribed, short-term until steroid tapered.
Purpose: Protect optic nerve if steroid elevates pressure.
Mechanism: Lowers fluid production or increases outflow in the eye.
Side effects: Depend on class; used under close supervision.

Regenerative,” and “stem cell drugs”

There are no approved systemic “immunity booster” pills, regenerative drugs, or stem-cell drugs for TSPK. Using such products can be unsafe or a waste of money. TSPK is best controlled with local ocular-surface care and topical anti-inflammatory medicines (steroids for short flares and steroid-sparing immunomodulators for prevention). Below are safer, evidence-based immunomodulatory strategies that serve the same goal—calming the local immune response—without unproven “stem cell” claims:

Safer immunomodulatory strategies (instead of “stem cell drugs”)

(Dosage and function described plainly; all require clinician guidance.)

Topical cyclosporine A 0.05–0.1% — 2×/day.
Function: Long-term controller that reduces flares. Mechanism: T-cell down-regulation on the ocular surface.
Topical tacrolimus 0.02–0.1% — 1–2×/day.
Function: Alternative long-term controller when cyclosporine is insufficient. Mechanism: Calcineurin inhibition → less inflammatory signaling.
Loteprednol 0.2–0.5% — Short bursts, then taper.
Function: Fast relief during active flares. Mechanism: Corticosteroid anti-inflammatory with “soft-drug” profile.
Fluorometholone 0.1% — Short bursts, then taper.
Function: Another low-potency steroid option for flares. Mechanism: Reduces epithelial immune activity.
Lifitegrast 5% (where available) — 2×/day.
Function: Steroid-sparing helper in recurrent disease. Mechanism: Blocks LFA-1/ICAM-1 interaction to curb inflammation.
Allergy control (olopatadine/ketotifen) — 1–2×/day in season.
Function: Prevents allergy-driven surface irritation that can “fan the flames.” Mechanism: Antihistamine + mast-cell stabilization.

If you ever see “stem cell eye drops,” “immune booster injections,” or “regenerative pills” marketed for TSPK, treat them as red flags and discuss with your ophthalmologist.

Dietary molecular supplements

(Dosage examples are typical adult ranges; confirm with your clinician, especially if pregnant, nursing, on blood thinners, or with medical conditions.)

Omega-3 fatty acids (EPA/DHA) — ≈1,000–2,000 mg/day combined EPA+DHA.
Function: Supports tear film quality and ocular surface comfort.
Mechanism: Anti-inflammatory lipid mediators that can reduce surface irritation.
Vitamin D — Check level; common maintenance 800–2,000 IU/day.
Function: Immune modulation and general ocular surface health.
Mechanism: Regulates immune responses; deficiency is linked with dry eye symptoms.
Vitamin A (dietary, not high-dose pills unless deficient) — From food; avoid excess supplements.
Function: Maintains a healthy corneal epithelium.
Mechanism: Essential for epithelial growth and mucin production.
L-carnitine — 500–1,000 mg/day.
Function: May lessen osmotic stress on the surface (adjunct in dry eye).
Mechanism: Osmoprotective effect on epithelial cells.
Taurine — 500–1,000 mg/day.
Function: Cellular protection and antioxidant support.
Mechanism: Stabilizes membranes and scavenges oxidative by-products.
Curcumin (with piperine for absorption) — ≈500–1,000 mg/day standardized extract.
Function: Systemic anti-inflammatory support.
Mechanism: Down-regulates NF-κB pathways involved in inflammation.
Green tea catechins (EGCG) — As brewed tea or standardized extract per label.
Function: Antioxidant and mild anti-inflammatory support.
Mechanism: Reduces oxidative stress that can sensitize the ocular surface.
Flaxseed (ALA source) — 1–2 tablespoons ground flaxseed/day or per capsules.
Function: Plant omega-3s that may help tear quality in some people.
Mechanism: ALA converts partly to EPA/DHA; also provides lignans and fiber.
Hyaluronic acid (oral) — Per product label; topical HA tears remain primary.
Function: Extra moisture support; best evidence is for topical use.
Mechanism: Water-binding polymer that hydrates tissues.
Zinc (avoid excess) — ≈8–11 mg/day total from diet/supplements.
Function: Supports epithelial repair and immune balance.
Mechanism: Cofactor in many enzymes for cell growth and healing.

Supplements are helpers, not replacements for medical therapy. Stop any supplement that causes side effects and inform your clinician.

Procedures/surgeries

TSPK almost never needs surgery. When procedures are used, they are usually for comfort or for special situations—not to “cure” TSPK.

Punctal plug insertion
Procedure: Tiny plugs placed into the tear drainage openings.
Why it’s done: Keeps more natural tears on the eye to improve lubrication in very dry patients.
Notes: Reversible and office-based.
Bandage contact lens placement
Procedure: A soft protective lens fitted in clinic.
Why it’s done: Short-term pain relief and smoother blinking during a bad flare.
Notes: Often combined with antibiotic prophylaxis; not a long-term solution.
Scleral lens fitting (specialty contact lens)
Procedure: Custom large lens that holds fluid over the cornea.
Why it’s done: For people with frequent, impactful flares and significant glare who need stable optics.
Notes: Non-surgical but procedural; requires expert fitting and hygiene.
Amniotic membrane placement (self-retaining device or sutured, select cases)
Procedure: A biologic membrane is placed on the eye surface.
Why it’s done: To calm severe surface inflammation or help epithelial healing if the surface is very irritated.
Notes: Rare in TSPK; more common in other surface diseases.
Phototherapeutic keratectomy (PTK) or superficial keratectomy (very rare)
Procedure: Laser or manual smoothing of the very top corneal layer.
Why it’s done: Considered only in exceptional, refractory cases with persistent surface irregularity despite optimal medical care.
Notes: Most TSPK patients do not need this.

Preventions and daily habits

Regular preservative-free tears during at-risk times (travel, AC, heavy screen days).
Sunglasses/hat outdoors to cut glare and UV.
Blink breaks and ergonomic screen setup.
Humidify dry rooms; avoid air blowing into eyes.
Stop smoking and avoid smoky spaces.
Treat allergies promptly to reduce background inflammation.
Maintain sleep, hydration, and stress control.
Pause contact lenses at first sign of a flare.
Keep a flare kit (tears, cold mask, sunglasses) ready.
Regular check-ups if you’ve needed steroid drops in the past.

When to see a doctor (red flags)

Strong light sensitivity, pain, or worsening blur that does not improve within 24–48 hours of using lubricants.
Visible discharge or crusting (possible infection).
You are using or just finished steroid eye drops and develop headache/eye ache or notice halos—these can signal raised eye pressure.
You rely on contact lenses and symptoms escalate quickly.
New systemic illness, fever blister/herpes history, or new medicines, and your eye symptoms change suddenly.
Any sudden drop in vision or one eye much worse than the other.

What to eat and what to avoid

What to eat (and drink):

Water regularly through the day.
Fatty fish (salmon, sardines, mackerel) 2–3×/week for EPA/DHA.
Colorful vegetables (leafy greens, carrots, peppers) for antioxidants and vitamin A precursors.
Nuts and seeds (walnut, flax, chia) for healthy fats.
Citrus and berries for vitamin C and polyphenols.

What to limit or avoid:

Excess alcohol, which dehydrates eyes.
Very spicy or high-sodium meals right before bedtime if they worsen morning puffiness.
Ultra-processed snacks high in trans fats, which may promote inflammation.
Excess caffeine late in the day if it reduces sleep quality.
Supplements without guidance, especially high-dose vitamin A or “immune boosters” making big claims.

Frequently asked questions (FAQs)

1) Is TSPK an infection?
No. TSPK is believed to be immune-mediated, not contagious. That’s why anti-inflammatory and immunomodulatory eye drops help.

2) Will TSPK make me blind?
Very unlikely. The spots are superficial and do not usually scar. Vision may blur during flares but typically returns to baseline when the flare calms.

3) Why does bright light hurt so much?
The rough spots scatter light. This scattering makes even normal light feel harsh. Sunglasses and controlling inflammation reduce this.

4) Do I need steroid drops forever?
No. Steroids are tools for short flares. To prevent repeat flares, many doctors use steroid-sparing drops (like cyclosporine or tacrolimus) long-term.

5) Are artificial tears enough?
Sometimes yes, especially for mild flares. For stronger flares, your doctor may add a short steroid burst and then switch to maintenance immunomodulators.

6) Can I wear contact lenses?
Yes, but avoid lenses during flares. If you need lenses and symptoms persist, a specialist might suggest scleral lenses for comfort and vision.

7) How long does a flare last?
Weeks to months. Good surface care and timely anti-inflammatory treatment can shorten flares and lengthen quiet periods.

8) Do blue-light glasses help?
They can reduce perceived glare for some people at screens, but the key is blinking, hydration, and proper lighting/ergonomics.

9) Can children get TSPK?
Yes, though it’s less common. Pediatric eye doctors use similar principles: lubricants, sunglasses, short steroid courses when needed, and careful monitoring.

10) Will I need surgery?
Almost never. Procedures like punctal plugs or amniotic membrane are for special situations; PTK is extremely rare in TSPK.

11) Are “stem cell eye drops” a good idea?
No. There are no approved stem-cell drugs for TSPK. Stick with proven therapies and discuss anything new with your ophthalmologist.

12) Can stress trigger flares?
Stress does not cause TSPK, but it can worsen symptoms by disturbing sleep, blinking patterns, and immune balance.

13) What if steroid drops raise my eye pressure?
Your doctor will monitor this. If pressure rises, the steroid will be tapered sooner, and pressure-lowering drops may be used temporarily.

14) What if my flare returns when I taper steroids?
This is common. A steroid-sparing plan (cyclosporine/tacrolimus) helps maintain control with fewer steroid bursts.

15) Is there a cure?
There is no once-and-for-all cure, but most people achieve good control with smart surface care and targeted anti-inflammatory therapy.
