Contact Lens–Induced Giant Papillary Conjunctivitis

ROUTINE — Conjunctiva

Symptoms

Itching (intense, often worse after lens removal).

Mucous discharge.

Contact lens intolerance or increased awareness.

Excessive lens movement on blink.

Clinical Findings

Exam technique

  • Upper lid eversion is mandatory; signs are localized to the upper tarsal conjunctiva.

Tarsal signs

  • Giant papillae (≥1 mm diameter); macropapillae (>2 mm).
  • Cobblestone appearance: discrete, raised, flat-topped fibrovascular papillae.
  • Central vascular tuft within each papilla.
  • Sparing of inferior tarsus (distinguishes from trachoma/vernal).

Lens & lid changes

  • Protein, lipid, or calcium deposits on the lens surface.
  • Mucous strands on the lens or tarsus.
  • High-riding lens (pushed superiorly by papillae during blink).
  • Pseudoptosis (late sign from chronic inflammation and lid edema).

Corneal status

  • Usually normal or mild superior SPK.
  • Any corneal infiltrate mandates culture to rule out microbial keratitis.

Etiology

Mechanisms

  • Mechanical: Repeated friction of the lens edge against the upper tarsus.
  • Immune: Type I and IV hypersensitivity to denatured proteins (lysozyme, albumin) on the lens surface.

Risk factors

  • Extended-wear and hydrogel lenses (higher protein binding than silicone hydrogel).
  • Older lens material and non-daily replacement schedules.
  • Preservative sensitivity (thimerosal, chlorhexidine, BAK).

Non-lens triggers

  • Ocular prostheses, exposed sutures, extruded scleral buckles, or glaucoma shunt tubes.

Red Flags

Persistent GPC despite lens cessation → switch to daily disposables or scleral lenses.

Corneal infiltrate or worsening SPK → rule out microbial keratitis; culture if suspicious.

Bilateral severe symptoms with atopy → systemic allergy workup.

Tarsal scarring or symblepharon → oculoplastic evaluation.

Investigations

Slit lamp

  • Upper lid eversion to document papilla size and tarsal extent.
  • Inspection for lens deposits and mucous strands.

Ocular surface

  • Fluorescein staining for SPK or epithelial defects.
  • Culture of any suspicious corneal infiltrates.

Treatment

Lens management

  • Preferred: Switch to daily-disposable soft lenses.
  • Alternative: Rigid gas-permeable (RGP) or scleral lenses.
  • Hygiene: Use hydrogen peroxide disinfection or preservative-free saline.

Topical therapy

  • Mast cell stabilizer/antihistamine (e.g., olopatadine, bepotastine, ketotifen) BID.
  • Severe cases: Low-potency topical steroid (loteprednol 0.5%, fluorometholone 0.1%) QID × 2 weeks.
  • Rule: No lens wear while on topical steroids.

Steroid-sparing / chronic

  • Topical cyclosporine (0.05% or 0.09%) or Lifitegrast 5%.

Clinical Pearl

GPC is a disease of "lenses and deposits"—switching to daily disposables often resolves what months of mast-cell stabilizers cannot.

Differential Diagnosis

  • Vernal keratoconjunctivitis (VKC)
  • Atopic keratoconjunctivitis (AKC)
  • Gelatinous limbal papillae
