Clinical Picture
- 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.

Famous quotes containing the word picture:
“But what now grips his fancy is her face,
And how the cunning picture holds her still
At just that smiling instant when her soul,
Grown sweetly faint, and swept beyond control,
Consents to his inexorable will.”
—Richard Wilbur (b. 1921)
