What you need to know


Slit Lamp Viewing:

• Diffuse beam • Direct illumination • Medium magnification (16x)

Grading:

  • Position: superior, nasal inferior, temporal
  • Grade 0: None
  • Grade 1: Slight injection of limbal vessels
  • Grade 2: Mild injection
  • Grade 3: Moderate injection
  • Grade 4: Severe injection

 


Incidence:

  • True incidence unknown although common in most lens types. Occurs to some degree with all hydrogel lenses, although may be mild with thin, mid-water hydrogels.

Aetiology:

  • Short-term clinical sign of corneal hypoxia –related to oxygen performance of lens
  • Inflammation (tight lens syndrome)
  • Mechanical irritation (trauma, poor lens fit)
  • Atopic/allergic reaction
  • Solution sensitivity
  • Infection

Symptoms:

  • Often none; depends on cause
  • Possible pain

Signs:

  • Engorged limbal blood vessels with possible subsequent neovascularisation
  • May be localised or full coverage, depending on lens type or aetiology, with conjunctival vessel involvement


What you need to recommend to your patients

Management:

  • Manage if ≥ grade 2 or if ≥ 1 grading scale interval increase or if symptoms occur
  • Cease lens wear until resolution. Refit with higher oxygen performance lens materials (Silicone Hydrogel (SiHy), higher Dk/t hydrogel, rigid corneal lenses (RCL))
  • Reduce wearing time or change to Daily Disposable (DD)
  • Optimise lens fit
  • Remove allergen
  • Change care system

Prognosis:

  • Good – depends on cause
  • Reversible
  • Noticeable “white-eye” difference between SiHy and traditional hydrogels

Differential Diagnosis:

Neovascularisation, superior limbic keratoconjunctivitis (SLK), keratitis, CLARE or tight lens syndrome, uveitis, acute glaucoma, intra-ocular infection

Important Safety Information:

ACUVUE® Contact Lenses are indicated for vision correction. As with any contact lens, eye problems, including corneal ulcers, can develop. Some wearers may experience mild irritation, itching or discomfort. Contact lenses should not be used in case of eye infections or any other eye conditions, or in case of a systemic disease that may affect the eye. For complete information, including contraindications, precautions and adverse reactions, please consult the Instructions for Use or visit our J&J website www.jnjvisionpro.co.uk
