The diagnosis and follow-up were performed by an expert ophthalmologist through a score based on ocular signs such as little and/or giant papillae, conjunctival hyperemia, keratitis, and Horner-Trantas dots
and on subjective ocular symptoms such as itching, photophobia, foreign body sensation, tearing, and mucous secretion according to the system described by each variable.
Characterised by ptosis, ropy mucous discharge, photophobia, large, non-uniform cobblestone papillae, Horner-Trantas dots, limbal nodules, neovascularisation, corneal shield ulcers, and itching.
Inclusion criteria being large cobblestone papillae, Horner-Trantas dots with any of these [active shield ulcer, macroerosion, limbal stem cell deficiency with conjunctivisation, coarse punctate epithelial keratitis (PEK), conjunctival granuloma, limbal pannus indicating severe annular limbal inflammation] .
In more severe cases there are limbal nodules and Horner-Trantas dots
. In mild cases topical anti-histamine drops and mast cell stabilisers can be used.
A characteristic manifestation of limbal vernal conjunctivitis is the presence of Horner-Trantas dots
, which are white, chalk-like dots composed of eosinophils and epithelial debris located at the limbus.
