- The image depicits Conjunctival hyperemia with papillary hypertrophy (cobblestoning) on the everted palpebral conjunctiva of the upper eyelid in a patient with vernal conjunctivitis/spring Catarrh/Warm Weather Conjunctivitis.
- It is a chronic form of ocular allergy that can potentially cause severe visual complications.
- It is Type I (IgE mediated) and Type II hypersensitivity response to exogenous allergens.
- Boys are primarily affected and usually from 5 years of age.
Signs include:
- Conjunctival hyperemia with papillary hypertrophy (‘cobblestoning’) reaching 7 to 8 mm in diameter in the upper tarsal plate.
- A thin, copious milk-white fibrinous secretion composed of eosinophils, epithelial cells and Charcot-Leyden granules.
- Limbal or conjunctival ‘yellowish-white points (Horner’s points and Trantas’ dots) lasting 2 to 7 days.
- An extra lower eyelid crease (Dennie’s line).
- Corneal ulcers infiltrated with Charcot-Leyden crystals; or pseudomembrane formation of the upper lid when everted and exposed to heat (Maxwell-Lyon’s sign).
Corneal signs in VKC:
- Shield ulcers
- Vernal plaques
- Subepithelial scarring
- Pseudo-gerontoxon resembles arcus senilus; it has a cupid’s bow outline.
