Colour Spill in Eyes - Ocular Chemical Emergency

This is a true ocular emergency. Colour dyes (fabric dyes, hair dyes, paint, industrial dyes) can cause significant chemical injury to the eye depending on their pH and chemical composition. Speed of response directly determines the prognosis.

Immediate First Aid (Before Hospital)

Start irrigation NOW - do not wait for a medical facility.

Flush immediately with tap water - open the eye as wide as possible and let clean running water flow over it continuously for 15-30 minutes
Head position - tilt the head so the affected eye is lower; turn the head so the water flows from the inner corner outward, avoiding contamination of the unaffected eye
Blink repeatedly during irrigation to allow water to wash under the eyelids
Remove contact lenses before or during irrigation if present
Do NOT rub the eye - rubbing embeds the chemical deeper into corneal tissue
Do NOT use milk, oil, or other home remedies - clean water is best if saline is not available

Seek Emergency Care Immediately

Go to an emergency department or call for help while irrigation is ongoing. Bring the container or label of the dye if possible.

What Happens in the Emergency Department

Assessment

Visual acuity test in all patients
Ocular pH check with litmus paper - goal is pH 7.4 (neutral)
Slit-lamp examination with fluorescein staining after irrigation

Continued Irrigation

1-2 litres of normal saline or Lactated Ringer's solution
A topical anaesthetic (e.g. proparacaine) is instilled first to reduce pain and help the patient cooperate
A Morgan lens may be used to deliver continuous irrigation
Irrigation continues until pH remains at 7.4 for 30 minutes after the last flush
Eyelids are double-everted to check for retained dye particles in the fornices

Grading of Injury (Roper-Hall Classification)

Grade	Cornea	Limbal Ischaemia	Prognosis
1	Clear (epithelial damage only)	None	Excellent
2	Hazy, iris visible	< 1/3	Good
3	Stromal haze, iris detail lost	1/3 - 1/2	Guarded
4	Opaque	> 1/2	Poor

Medical Treatment

Grade 1 & 2: Topical antibiotic ointment for ~1 week; topical steroids and cycloplegics if needed
Grade 3 & 4 (severe): Hospital admission required
- Topical corticosteroids (e.g. fluorometholone 1% or prednisolone 0.5%) for ~1 week to reduce inflammation
- Cycloplegics + mydriatics to prevent pupillary constriction and reduce pain
- Carbonic anhydrase inhibitors (e.g. acetazolamide) for up to 2 weeks if intraocular pressure is elevated
- Vitamin C (ascorbate) supplementation to support collagen synthesis
- Surgical options for severe cases: amniotic membrane patching, anterior chamber paracentesis, or corneal transplant

Key Points About Colour Dyes Specifically

Hair dyes are often mildly alkaline (pH ~9-10) or contain oxidising agents (hydrogen peroxide) - both can damage corneal epithelium
Fabric/textile dyes may contain acid or reactive chemicals that cause coagulative injury
Industrial dyes can be strongly acidic or alkaline
Even "mild" dyes can cause conjunctival inflammation and corneal abrasion; never assume a dye is safe without pH assessment
Alkali-type dyes are more dangerous because they cause liquefaction necrosis and penetrate deeper into the eye; acid-type dyes form a barrier (coagulation necrosis) and tend to cause less deep penetration

Warning Signs Requiring Urgent Escalation

Significant decrease in vision
Severe pain persisting after irrigation
Corneal clouding or whitening
Scleral whitening (limbal ischaemia - a sign of severe injury)
Elevated intraocular pressure

Ophthalmology consultation is mandatory for all significant exposures. Even if the initial injury appears mild, close follow-up is needed because complications (corneal ulceration, glaucoma, corneal perforation) can develop days later.

Can i use eye drops like cipro

Can You Use Ciprofloxacin (Cipro) Eye Drops?

Yes, but only after irrigation - not instead of it.

Here is exactly how ciprofloxacin eye drops fit into the picture:

Role of Ciprofloxacin Eye Drops

Ciprofloxacin 0.3% ophthalmic solution is a fluoroquinolone antibiotic used to prevent or treat bacterial infection. After a chemical/dye splash injures the corneal surface, the damaged epithelium becomes vulnerable to infection - and antibiotic drops help protect it.

When to use them:

After completing full eye irrigation (15-30 min with water/saline)
If there is a corneal abrasion confirmed on examination
As prophylaxis after the chemical injury, especially in contact lens wearers

Typical dose: 1-2 drops, 4 times per day for 7 days

Important Points

Point	Detail
Irrigation comes first	Cipro drops do NOT neutralise or wash out the dye. Do irrigation first, always
Contact lens wearers	Ciprofloxacin is specifically recommended for contact lens wearers because it covers Pseudomonas (a dangerous corneal pathogen)
Do not use as anaesthetic	Cipro does not relieve pain - do not overuse drops trying to numb the eye
Do not use topical anaesthetic drops at home	Proparacaine/tetracaine are used in ED only - repeated home use retards healing and causes corneal scarring
Do not self-prescribe steroids	Steroid drops (like dexamethasone) should only be started under ophthalmologist guidance

What Cipro Eye Drops Will NOT Do

Will not flush the dye out
Will not neutralise the chemical
Will not heal the cornea faster
Will not reduce inflammation from the chemical itself

Bottom Line

Ciprofloxacin eye drops are a reasonable and appropriate antibiotic to use after the eye has been properly irrigated. They help prevent infection in the damaged corneal tissue. However, irrigation is still the single most important step - it must be done first and thoroughly. The patient still needs an ophthalmology review to assess how much damage has occurred.
