Kite‑Flying Related Eye Injury (Traumatic Keratoconjunctivitis)

Overview

Traumatic keratoconjunctivitis is an inflammation of the cornea (the clear front window of the eye) and the conjunctiva (the thin membrane that lines the eyelid and covers the white of the eye) that results from a direct mechanical injury. When the injury is caused by a kite‑string—especially a “manja” or “glass‑coated” string used in many Asian kite‑flying festivals—the condition is commonly referred to as a kite‑flying related eye injury (KFR‑EI). The high‑tension string can act like a surgical scalpel, slicing the surface of the eye in a fraction of a second.

Although kite flying is a beloved cultural pastime in many countries (India, Pakistan, Bangladesh, Nepal, Thailand, and parts of the Middle East), eye injuries from kite strings are surprisingly common. A retrospective study from the All India Institute of Medical Sciences (AIIMS) reported 1,748 eye trauma cases over a 5‑year period, with ≈30 %1. Most victims are males aged 10–30 years, but children and even by‑standers can be affected.

Symptoms

Symptoms usually appear within minutes of the injury and can range from mild irritation to severe vision loss. Common manifestations include:

• Acute pain or burning sensation – often described as “sharp” or “stabbing.”
• Redness (hyperemia) – diffuse or localized to the site of impact.
• Photophobia – heightened sensitivity to light.
• Tearing (epiphora) – excessive watery discharge.
• Foreign‑body sensation – the feeling that something is stuck in the eye.
• Blurred or decreased vision – may be transient or persist if the cornea is scarred.
• Swelling of the eyelids (eyelid edema).
• White or grayish opacity on the cornea – visible on slit‑lamp examination.
• Bleeding (hyphema) or subconjunctival hemorrhage – rare but possible with deep lacerations.
• Floating particles or “floater” sensation – if the trauma disrupts the vitreous humor.

Causes and Risk Factors

Primary cause

The injury occurs when a high‑tension kite‑string contacts the ocular surface at high velocity. In many regions, kite strings are coated with:

• Glass powder or crushed metal (manja), creating a micro‑blade effect.
• Adhesive or resin that hardens the string, making it less elastic.
• Electrical wires (rare) used for lighting kites, which can cause both mechanical and electrical burns.

Risk factors

• Age & gender – Young males are the most frequent participants.
• Outdoor location – Open fields, beaches, or rooftops where kites are launched.
• Poor protective equipment – Lack of safety glasses or goggles.
• High‑wind conditions – Increases string tension and speed.
• Use of “manja” strings – The glass‑coated variant raises the risk >10‑fold.
• Inexperience – New flyers may misjudge string trajectory.
• By‑stander exposure – Spectators, especially children, are often hit unintentionally.

Diagnosis

Prompt evaluation by an ophthalmologist is essential. Diagnosis is primarily clinical but may involve several ancillary tests:

History taking

• Mechanism of injury (type of string, speed, angle).
• Time since exposure.
• Previous ocular conditions (dry eye, contact lens wear, prior surgery).

Physical examination

• Visual acuity test – assesses the impact on vision.
• Slit‑lamp biomicroscopy – visualises corneal lacerations, abrasions, and conjunctival involvement.
• Fluorescein staining – highlights epithelial defects; the dye appears green under blue light at the site of injury.
• Seidel test – checks for leaking aqueous humor if a perforation is suspected.

Imaging (when indicated)

• Anterior segment optical coherence tomography (AS‑OCT) – measures depth of corneal injury.
• Ultrasound B‑scan – evaluates posterior segment if the view is obscured.

Treatment Options

Treatment aims to control inflammation, prevent infection, promote healing, and preserve vision.

Immediate First‑Aid (self‑care)

• Do not rub the eye.
• Rinse gently with sterile saline or clean water for at least 15 minutes.
• Cover the eye with a clean, non‑adhesive dressing while seeking medical help.

Medical Management

1. Topical antibiotics – Broad‑spectrum drops (e.g., moxifloxacin 0.5 %) to prevent bacterial infection; used 4–6 times daily for 5–7 days.
2. Topical corticosteroids – Low‑dose prednisolone acetate 1 % to reduce inflammation; taper over 1–2 weeks under supervision.
3. Lubricating eye drops or gels – Preservative‑free artificial tears every 2 hours to keep the ocular surface moist.
4. Pain control – Oral acetaminophen or ibuprofen; consider topical NSAIDs (e.g., ketorolac) if pain is severe.
5. Cycloplegic agents – Homatropine 2 % eye drops to relieve ciliary spasm and photophobia.

Procedural Interventions

• Corneal epithelial debridement – Gentle removal of loose epithelium to allow proper healing.
• Bandage contact lens – Helps protect the cornea, reduces pain, and promotes re‑epithelialisation.
• Suturing or lamellar keratoplasty – Required for deep or large lacerations (>2 mm) to restore structural integrity.
• Amniotic membrane transplantation – Provides a biological scaffold for healing in severe cases.

Follow‑up care

Patients should be reviewed within 24–48 hours, then weekly until the cornea has fully healed (usually 2–4 weeks). Visual acuity and corneal topography are repeated to detect early scarring.

Living with Kite‑Flying Related Eye Injury (Traumatic Keratoconjunctivitis)

Even after successful treatment, patients may need to adapt daily habits while the eye recovers.

• Protect the eye – Wear UV‑blocking sunglasses outdoors for at least 2 weeks.
• Limit screen time – Reduce glare and digital eye strain; use artificial tears if needed.
• Avoid contact lenses – Discontinue use until the cornea is completely healed and cleared by the ophthalmologist.
• Maintain hygiene – Wash hands before applying eye drops; keep pillowcases clean.
• Monitor symptoms – Note any increase in pain, redness, or sudden vision change and report promptly.
• Gradual return to activity – Re‑engage in sports or kite flying only after clearance (usually 4‑6 weeks).

Prevention

Because many injuries are avoidable, public‑health measures and personal practices are crucial.

• Wear protective eyewear – Polycarbonate safety glasses or goggles with side shields whenever handling or flying kites.
• Use non‑coated, low‑tension strings – Opt for cotton or synthetic strings without glass coating.
• Regulate kite festivals – Municipalities should ban glass‑coated “manja” and enforce safety zones away from crowds.
• Educate children and by‑standers – Conduct safety briefings before festivals.
• Maintain safe distances – Keep spectators at least 30 feet (≈10 m) from the flight line.
• Check wind conditions – Avoid flying in gusts >20 km/h that increase string tension.

Complications

If left untreated or inadequately managed, traumatic keratoconjunctivitis can lead to serious sequelae:

• Corneal scarring – Permanent opacity causing reduced visual acuity.
• Corneal ulcer or infectious keratitis – May progress to perforation.
• Endophthalmitis – Intra‑ocular infection, a vision‑threatening emergency.
• Secondary glaucoma – Elevated intra‑ocular pressure from inflammation.
• Dry eye syndrome – Resulting from damage to conjunctival goblet cells.
• Astigmatism – Irregular corneal curvature post‑scar.
• Psychological impact – Anxiety or fear of future eye injury, especially in children.
