Urgent Care Management of Nail Glue (Cyanoacrylate) in the Eye

Begin immediate copious irrigation with sterile saline to remove unpolymerized adhesive, avoid any mechanical manipulation of bonded glue, apply preservative-free lubricants every 2 hours, and arrange urgent ophthalmology consultation for fluorescein examination and ongoing management. 1

Immediate Actions at Presentation

Do NOT Do These Things

  • Never attempt mechanical removal or manipulation of adhesive that has already bonded to ocular tissues – this causes corneal epithelial defects and potentially full-thickness corneal damage 1
  • Do not blindly sweep the fornices with cotton swabs or glass rods – this creates additional mechanical trauma to already compromised tissue 1
  • Do not initiate topical corticosteroids without ophthalmology supervision – steroids mask signs of infectious keratitis and are dangerous when corneal epithelial defects are present 1

What You Should Do First

  • Irrigate copiously with sterile saline immediately to flush out any unpolymerized adhesive before it bonds to ocular tissues 1
  • Apply preservative-free lubricants (hyaluronate or carmellose drops) every 2 hours to maintain corneal hydration and comfort 1
  • Arrange urgent same-day ophthalmology consultation for comprehensive slit-lamp examination with fluorescein staining to assess corneal and conjunctival epithelial integrity 1

Ophthalmology-Directed Management

Once the ophthalmologist examines the eye and identifies corneal epithelial defects:

Infection Prophylaxis

  • Initiate prophylactic broad-spectrum topical fluoroquinolone (moxifloxacin or levofloxacin) four times daily if any corneal epithelial defects are present on fluorescein staining 1

Corneal Protection

  • Consider bandage contact lens placement (thin, high water content, high oxygen permeability) to protect the cornea and provide comfort if epithelial defects are present 1
  • Warn patients that bandage contact lenses increase microbial keratitis risk 10- to 15-fold and they must immediately contact ophthalmology if symptoms worsen 1

Follow-Up Protocol

  • Schedule daily ophthalmologic follow-up to monitor for infectious keratitis (increasing pain, redness, or photophobia) 1

Long-Term Management Strategy

Allow spontaneous separation of bonded adhesive over time (typically 6 weeks or longer) rather than attempting mechanical removal – this is the cornerstone of management once glue has polymerized 1

  • Maintain frequent preservative-free artificial tears if adhesive has bonded to ocular tissues 1
  • Cyanoacrylate exerts minimal thermal, chemical, or toxic effects on the ocular surface and has a very favorable prognosis with conservative management 2

Why This Approach Works

The key distinction is between unpolymerized versus polymerized adhesive:

  • Unpolymerized glue can be flushed away with irrigation 1
  • Once polymerized (bonded), mechanical removal causes more harm than waiting for spontaneous separation 1, 2
  • Visual function returns to normal in all patients managed conservatively, with no persistent tissue damage 2

Common Pitfalls in Urgent Care

  • Attempting to peel or scrape off bonded glue – this is the most common error and causes severe corneal abrasions 1, 3
  • Delaying ophthalmology referral – same-day consultation is mandatory to assess extent of injury 1
  • Failing to provide adequate lubrication – the eye needs every-2-hour drops to prevent desiccation during the healing phase 1
