Vernal keratoconjunctivitis (VKC) or Spring catarrh is a recurrent, bilateral, and self-limiting inflammation of conjunctiva, having a periodic seasonal incidence. ==Sign and symptoms== *Symptoms- VKC is characterised by marked burning and itchy sensations which may be intolerable and accentuates when patient comes in a warm humid atmosphere. Associated symptoms include mild photophobia, lacrimation, stringy discharge and heaviness of eyelids. *Signs of VKC can be described in three clinical forms. #Palpebral form- Usually upper tarsal conjunctiva of both the eyes is involved. Typical lesion is characterized by the presence of hard, flat-topped papillae arranged in cobblestone or pavement stone fashion. In severe cases papillae undergo hypertrophy to produce cauliflower-like excrescences of 'giant papillae'. #Bulbar form- It is characterised by dusky red triangular congestion of bulbar conjunctiva in palpebral area, gelatinous thickened accumulation of tissue around limbus and presence of discrete whitish raised dots along the limbus (Tranta's spots). #Mixed form- Shows the features of both palpebral and bulbar types. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vernal keratoconjunctivitis」の詳細全文を読む スポンサード リンク
